Stop! There's a better way.

This snippet is available as a plugin with Gravity Perks, a suite of over 47 premium Gravity Forms plugins!

View Plugin Buy Gravity Perks

We wrote a snippet that will allow you to create a dynamic naming template for your uploaded Gravity Form files. This includes the ability to prepend, append or generate from scratch custom file names. You can use merge tags to include user input in your new file names.

Here are a couple use cases where this snippet might be useful:

  1. Include the name of the submitting user either before or after the file name.
  2. Include an event name in the file name to better categorize which files belong to which events.

For example, given an original file name of mountains.png and a template of {Name (First):1.3}-{Name (Last):1.6}-{filename}, the final image name would be Jordan-Smith-mountains.png

Getting Started

  1. Check requirements
  2. Install the snippet
    • Copy and paste the entire snippet into your theme’s functions.php file.
  3. Configure the snippet
    • Once you have installed the snippet, find the snippet configuration section located at the bottom of the snippet code.
    • Replace the form_id with the ID of your form.
    • Replace the field_id with the field ID of your File Upload field.
    • Replace the template with your custom file name template.

Usage Examples

First and Last Name

new GW_Rename_Uploaded_Files( array(
	'form_id'  => 628,
	'field_id' => 3,
	'template' => '{Name (First):1.3}-{Name (Last):1.6}-{filename}', // most merge tags are supported, original file extension is preserved
) );

In this example, we are prepending the first and last name from the form to easily identify who submitted the file. Most merge tags are supported using this method and the original file extension is preserved.

Form Title Merge Tag

new GW_Rename_Uploaded_Files( array(
	'form_id'  => 12,
	'field_id' => 18,
	'template' => '{form_title}-{filename}', // most merge tags are supported, original file extension is preserved
) );

In this example, we are prepending the title of the form to the filename to quickly identify which form the file was uploaded to.

Static Text

new GW_Rename_Uploaded_Files( array(
	'form_id'  => 628,
	'field_id' => 5,
	'template' => 'static-file-name',
) );

You can use any text you’d like, just make sure to add the {filename} merge tag somewhere in there.

Ignore Extension

new GW_Rename_Uploaded_Files( array(
	'form_id'          => 628,
	'field_id'         => 5,
	'template'         => 'static-file-name',
	'ignore_extension' => true,
) );

By default, this snippet takes the extension into consideration when renaming files. For example, static-file-name.jpg is different from static-file-name.png. You can change this behavior to ignore the extension of a file so in this scenario static-file-name.png would be renamed to static-file-name1.png as there’s already a static-file-name file uploaded.

Parameters

  • form_id (integer) (required)

    Your Form ID. There is no default value.

  • field_id (integer) (required)

    The Field ID of the file upload field. There is no default value.

  • template (string or merge tag) (required)

    This is the template that controls how the file will be rewritten. The value can be either a static string or a merge-tag(s). There is no default value.

You never need to include the file extension in your template. It will automatically be included.

    Hello,

    I’m experiencing an issue with filenames containing UTF-8 characters, such as Persian or Arabic characters. When uploaded, these characters are being replaced with unknown characters. Could you please enhance this code to support UTF-8 characters? Your assistance with this matter would be greatly appreciated.

    Thank you in advance.

    Bonjour Merci pour cette explication et ce code qui fonctionne parfaitement ! Il renomme bien mes fichiers qui sont hébergés sur mon site par contre lors de la validation de mon formulaire gravity form en ligne une notification part vers les intéressés en joignant un fichier zip avec tous les fichiers ! Là mon problème c’est que ces fichiers ne sont malheureusement renommés ! connaissez vous une solution à ce problème ? Il faudrait que la modification du nom se fasse dès que la personne joint sa pièce jointe au formulaire et pas au moment de l’envoie je pense ! merci par avance

    Hi- Thanks for the snippet! The one issue I’m having is that the {filename} merge tag you reference in the examples doesn’t carry over to the new filename, like in the ‘mountains.png’ example above.

    Filename prior to upload: aJ19p_So.pdf

    new GW_Rename_Uploaded_Files( array( ‘form_id’ => 2, ‘field_id’ => 32, // most merge tags are supported, original file extension is preserved ‘template’ => ‘2_{filename}’, ) );

    Resulting filename: 2_filename.pdf

    I feel like I’m missing something really obvious here…

    How can I programmatically populate a hidden field value (based on values submitted on other fields), in a way that the hidden field will be populated and used in the rename template?

    i.e. Field One (ID:1) – user will submit a value Field Two (ID:2, hidden) – my code will calculate this value based on the user submission

    ‘template’ => ‘{Field Two:2} xyz’

    I have tried using different actions and filters with different priority paramters, but to no avail…. please help.

    Hello,

    I’m using WPCode and it works when I only put two parts of configurations.

    new GW_Rename_Uploaded_Files( array( ‘form_id’ => 1, ‘field_id’ => 16, // most merge tags are supported, original file extension is preserved ‘template’ => ‘{entry_id}/{filename}’, // Ignore extension when renaming files and keep them in sequence (e.g. a.jpg, a1.png, a2.pdf etc.) ‘ignore_extension’ => false, ) );

    new GW_Rename_Uploaded_Files( array( ‘form_id’ => 1, ‘field_id’ => 22, // most merge tags are supported, original file extension is preserved ‘template’ => ‘{entry_id}/{filename}’, // Ignore extension when renaming files and keep them in sequence (e.g. a.jpg, a1.png, a2.pdf etc.) ‘ignore_extension’ => false, ) );

    But when I put all my code into the snippet, it will show “We encountered an error activating your snippet, please check the syntax and try again.” “Snippet not activated, the following error was encountered: syntax error, unexpected ‘ ‘ (T_STRING), expecting ‘)'”

    I’m not sure is there any problem with my code or it’s the plugin’s problem?

    Thanks for a great plugin. I would like the image the user uploads to be named after the role it is a member of and saved to a folder.

    It should be saved in /wp-content/uploads/company/ and named rolename.jpg . Is this possible?

    I’m using ultimate member, so I’ve tried several different ways like these shortcodes: ‘template’ => ‘{um_display_role}’, ‘template’ => ‘[um_display_role]’, But then only the file name will be um_display_role.jpg.

    If the role is named company, then I want the file to be saved as company.jpg . If the file already exists, I want it to be overwritten and of course only saved in /wp-content/uploads/company/ .

    Can you help me with that?

      Hi Robin,

      The {um_display_role} shortcode wouldn’t work when used as the value for the template parameter. What you can do is to dynamically populate a hidden field on the form with the role of the user and then use the merge tag of the hidden field as the value for the template parameter to rename the file with the user role.

      You can’t have a white space in a filename, because WordPress would replace it with a dash and it will also sanitize any special character including brackets by removing them.

    Hello. This is a great snippet, thanks so much for making it available. I do have one issue, though:

    I am prepending unique identifiers to file names in files uploaded by customers. That part is working great. However, administrators utilize GravityView to access the same form wherein they will occasionally make an edit to other entries. When that happens, even if it’s an edit to a totally unrelated entry, the renamed files get renamed all over again. For example, a file may start out as IMG1000.jpg, it gets uploaded and renamed to unique_identifier_IMG1000.jpg, but then it gets renamed yet again to unique_identifier_unique_identifier_IMG1000.jpg if the administrator edits any entry in the form. Is there a way to prevent this renaming duplication from happening? Thanks in advance for your help.

      Hi Nicola,

      If you want to use the file rename snippet on more than one file upload field and on multiple forms, you only have to set up multiple configurations. You don’t have to duplicate the entire snippet, but just the configuration part which will create multiple instances of the Class. Here is an article on how to apply a class-based snippet multiple times.

      I hope this helps.

    Can anyone think of a way i can get the category slug instead of the category name? This is for a contest entry, so to make a random number, I’m grabbing some mixed up time stamp. ($result = $date->format(‘uYHmids’);)

    ‘template’ => ‘{Category:9}-‘.$result,

    Field 9 on my form is the Post field Category, but i’d prefer to pull in the slug instead Could there be a hidden field on the form maybe that i could use to populate with the category slug once the user fills in the Category field?

    Or any other thoughts?

      That wouldn’t work. The output format for a Date field’s merge tag is set by the Date Format option in the field settings. Change this to yyy-mm-dd and the file will be renamed accordingly. You can’t also have slashes in the file name so this format, yyyy/mm/dd, won’t work.

      Hi Shak,

      That is the configuration for the snippet. You’re to replace or update the value for the template key with the name you want to use to rename the file. If you’ll be getting the name from another field on the form, then you’ll update the ID of the merge tags accordingly.

      I hope this helps.

      Additional info that may be useful – the redirected folder is not in web root — it’s confidential data, so we’re auto-saving it to an external mount — /share (as an example) — I’ve also removed the URL in the upload path redirect code as there won’t be a path that’s accessible from the dashboard or email.

    Hi, This is great, thank you!

    Is it possible to change a merge field to lowercase when assigning the template? something like this:

    ‘template’ => strtolower(‘{:3}’),

    Also, when an image with the same name is uploaded, a number are automatically added. is it possible to add a – before the number so it reads image-1.jpg and not image1.jpg

      Samuel Bassah Staff July 2, 2021 at 10:10 am

      Hi Schalk,

      Changing the merge field to lowercase wouldn’t work like that. The template parameter expects a static value or a merge tag. You’ll have to change the field value to lowercase after submission but before the entry is created so that the merge tag picks up the lowercase value.

      To add a dash when there is an image with the same name, you’ll have to customize the snippet. If you have an active Gravity Perks License, you can get in touch with us via our support form, so our developers can take a look into this.

    I am trying to get the date to appear in the name of the my uploaded file, I tried using the merge tag of {Date:3}, {Date:3.1} (and .2 / .3) and {Date:3:value}, I am not wanting the date to appear as a date of 2/8/2021, but 2021-02-08 would be perfect, this way my client can see images in date order for example.

    Any thoughts?

    Thanks!

    Ken

    Very useful code!

    Is it possible to strip out special characters from the merge tags? I have a PHP function that does that, but can I insert PHP that calls a function inside your code snippet or will it break it?

    BTW I got 3 gravity perks last week, the nested forms rock!

      What you can do is extend our class with your own and then modify the clean function to do any kind of sanitization you want.

      class Your_Rename_Uploaded_Files extends GW_Rename_Uploaded_Files { function clean( $str ) { return $str; } }

    Thanks for this code – it’s been really useful!

    I’ve been having an issue recently where a small number of files renamed using this snippet end up being saved as zero bytes in size.

    There’s no obvious pattern to the affected files themselves, and in some cases the issue affects only a subset of files uploaded along with a single form submission.

    I see no errors in the Apache or PHP logs that could shed light on the problem, and I haven’t been able to reproduce the problem myself. My best guess right now is that renaming is sometimes kicking in before the file uploads have finished, perhaps due to load on the server – is that a possibility?

    If so, is there any way to ensure the uploads are definitely complete before renaming triggers? (Even just a way to ensure the original file isn’t lost would be helpful; I can’t find them in GF’s temporary upload folder.) And if not, can you think of any other explanations?

    Thanks,

      Hi Ben,

      I haven’t experienced such before so I’m guessing this is an issue related to your server. You may want to check out our GP Media Library Perk, which enables the feature to automatically import uploaded files to the WordPress Media Library when the form is submitted. This can help ensure that you don’t lose any uploaded files in case you don’t find them in the GF Temporary upload folder.

      Hi Albert,

      You can get the Current site/blog ID with this get_current_blog_id();, you can then put the snippet configuration inside an if statement to check if the current site id is equal to the ID of the site you want to target. Something like this should work for you.

      if (get_current_blog_id() == 4 ){ new GW_Rename_Uploaded_Files( array( 'form_id' => 628, 'field_id' => 3, 'template' => '{Name (First):1.3}-{Name (Last):1.6}-{filename}' ) ); }

      I hope this helps.

    Thanks for the clear instructions. It’s works on one image. In my form I have more than one image to be renamed. Do I need to use the whole code snippet each time for a new FieldID in the same form? Example Form ID is the same, Field ID changes, and naming works as your above instructions.

    In fact, I’d like to use the snippet once and the rename instruction multiple times and for different forms. Is this possible? Then I just concentrate the renaming functionality in one place.

      Hi Stuart,

      If you want to use the file rename snippet on more than one file upload field, you can create multiple copies of just the configuration. You don’t have to duplicate the entire snippet, but just the configuration part which will create multiple instances of the Class. Here is an article on how to apply a class-based snippet multiple times.

    I have 4 file upload fields per form entry. Each of these 4 upload fields are multi upload.

    I would want file name to be “Postage[EntryID]X” Where entry ID is the form entry ID and X is the upload number, so first upload is 1, then 2 etc.

    How do I go about that (a bit confused because I have multi-upload and multiple fields? Thanks

      Hi Chelsea,

      You can use the {entry_id} merge tag to insert the entry ID into the renamed file, however numbering the files inside a multi-upload field isn’t currently supported.

      What you could do instead is use GF Nested Forms with a Single File upload field inside the Nested Form. You could then use the :count merge tag modifier in a field in the Nested Form to count the number of uploaded files, as shown in this article.

    I have a WP Multisite set up with http://www.mainsite.com/subsite/... format. I have plugins for Gravity Forms and Wp DataTables with Gravity Forms integration. I also have the Gravity Perks installed. My sub-sites are designed for separate use/access by separate clients. The sub-sites each have a number of Gravity Forms that are ‘checklists’ collecting info on different things. A number of the forms are checklists for reviewing documents and they have a file upload field to enable the client to upload a pdf copy of the document that they reviewed.

    Can this snippet be applied to work on a Multi-site set up for a number of different forms each with a file upload field?

    On each form I use the GF Perks Unique ID to create a unique sequential number for each submitted form. Is it possible for the upload file to be include this in the new file name?

    For example a file to be renamed as “XX00123Company Name” where XX00123 is the Unique ID sequential number and Company Name is the value input for a given company name field in the form.

    As I say I will have another separate form for, say, a legal document checklist with another Unique ID, say. “LG001” and, say, a document title name field, say, “Trust Deed” that I would want the file upload to be saves as “LG001_Trust Deed” .

    As I am using WP Multisite I can See Gravity is already storing the upload files in the gravity form folders under separate site number folders. I would however like to avoid it creating its subfolders for Year and Month of submission. ( I know there is another snippet for defining the path which I ope to use for this)

    How can I apply your snippet on Multisite and for different forms? Am I right in thinking the functions.PHP sits at Network level so I think I need the snippet to take account of the site number to ensure the files are save in the folders for each site?

    I would be grateful for your advice

      Hi Chris,

      This snippet supports GF Unique ID. Simply insert the merge tag for your Unique ID field in the template parameter.

      Instead of installing the snippet Network wide, I suggest using the Code Snippets plugin to manage the snippets on a per-site basis.

    I have a photo upload form where I direct people to name the photos in the order they want them displayed, ex: 1.jpg, 2.jpg etc.

    By default, multiple uploads of 1.jpg and 2.jpg etc will be renamed 11.jpg, 21.jpg etc.

    I thought I could use this function with the Gravity Wiz Unique ID add on to uniquely name the files as 00011-1.jpg etc, but it still adds on numbers to the filename on submission.

    Is there a way to use this function to keep the order without adding on an additional number for duplicate file names?

      Hi David – thanks for the reply. I’m trying to use this solution to uniquely rename uploaded files because users will upload files with the same name. So user1 could upload photo1.jpg and user2 could also upload photo1.jpg.

      I was hoping to use this function with GW’s unique id to rename them but it looks like it renames them but after the default rename that happens when multiple files get uploaded with the same name. So I lose the original name. Does that make sense?

      Well, turns out that GF version was not the issue but rather WP 5.*. I have a function that allows me to specify the upload folder by form id. So when the rename function tried to do it’s thing it was getting all confused because it tried to use the default upload path. Because of this, you can’t use the GFFormsModel::get_physical_file_path function. It actually did nothing due to the incorrect path vs url problem.

      Took me a long time to debug it…but finally did. I fixed it by creating my own $this->_get_physical_file_path function:

      http://snippi.com/s/uu1ctgf

      @Antoone – we’ve needed the admin label (value) for one of our forms as well. We have competitors uploading an .mp3 file to use as part of a performance and need those files renamed to match the division and name of the competitor.

      Here’s what works for us to populate the admin value instead of the field label for the ‘Division’ component of the naming.

      ‘template’ => ‘{Division:2:value}-{Name (First):3.3}-{Name (Last):3.6}’

      Essentially, put :value trailing the field reference.

    Hi I was redirected here from GF. My question relates to a file upload from the front end when and used by non-technical staff. I have a member of staff who generates a pdf file containing the latest information, they will then upload to wp, and when the page is next called in wp it uses the latest pdf file. The issue I have is that when GF uploads the file because one already exists by that name a suffix is added to the file being uploaded, which of course means the wp page does not open the new file. GF suggest that this snippit might do the trick. I’m already a GW client using the Populate Anywhere perp. Thanks Michael

    I’m currently hacking this code to run it for any form that have one or more upload fields. Therefore I modified is_applicable_form & is_applicable_field functions : http://snippi.com/s/9w1f0jc (note : with these hacks, form_id and field_id parameters won’t be used anymore) Seems to work as a POC, but maybe you’d like to refine/correct it ?

    What I’d like also is to set the template parameter so that the field name is added among – say- last name field and original filename. Can I use a “merge tag” like in parameters array or should I hack later, while in the loop ?

      Also, I noticed that my hack has a flaw; the form will be submitted (and confirmation sent) as many times as there are upload fields in the form. Sure have to add some controls to prevent this … any idea ?

      HI David, as mentioned above, I’m facing a problem I cannot solve by myself. If my form contains more than one fileupload field, everything seems to be ok but the confirmation message is sent as many times than there are fields.

      I’ve been trying several combinations, hooking on gform_disable_notification filter with no luck, I’m probably missing something obvious here …

      Basically, what I do is : 1. In the parameters array, I’ve added a “field_nb” parameter (defaulted to 0) 2. In the “is_applicable_form” function, while looping into the fields to find (eventually) fileupload file types, I increment this parameter so that we know how many fields should be treated before sending notification. 3. I tried various combinations I’m to shameful to share here (hooking on gform_disable_notification) with no luck … Basically I just wanted to switch notification for this particular entry off by default and reactivate it (in the ‘foreach’ fields loop) only for the last field. I guess I’ve reached my limit here … help very welcome :)

    This is working great. Just one question to see if this is possible. Would it be possible to change the file name AND convert to uppercase in the process? I have a field in GF that I’ve converted to uppercase before saving in the db. This field is also being used to create a query string that gets passed to the form where the file upload and renaming happens. This query string doesn’t use the uppercase value saved in the database but rather whatever the user put in.

    Thanks!

    Hi,

    when creating directories by using “/” on the templates there is a case that is not handled correctly by version 2.5. As our website serves German and international audiences, our field names are like “Company / Firma”. This leads to a mere tag like “{Company / Firma:1}” and the slash within the brackets is also interpreted to crate a directory – but should not.

    Do you see chance to make the script in this regard bullet-proof? It would be great!

      I tried to add a slash to create subfolder but it did not work. Is it because a slash only works between {fields}?

      What I did:

      {Markenname:7} – {entry_id}/Logo/{filename} and {Markenname:7} – {entry_id}/Pictures/{filename}

      Any idea?

    Hi, I have so many forms on my site, many of which have file uploads that I would like to customize filenames for. Is there a way to configure this for ALL forms, instead of applying to specific forms?

    Thanks in advance.

      This is not currently supported. The primary hold-up right now is that you must specify the field ID which typically is not the same across multiple forms.

    I don’t understand how this is working, I must missing something.

    Where does {Name (First):1.3}-{Name (Last):1.6 come from, how can I relate this to my form? is this the name of the input field? what does 1.3 and 1.6 relate too?

      Hi Dan, they are merge tags that you will need to manually enter. At a minimum a merge tag must include the field ID (and input ID for multi-input fields). The merge tag for a field of ID 1 could be as simple as {:1}. The merge tag for the first name input of a field with ID 2 would be {:2.3} where 2 is the field ID and 3 is the input ID.

    Hi,

    First, thanks for that great snippet. I install it and its works great.

    But, after i added it, there was a strange hitch. The gravity forms can not export records of the forms to the file. Instead it displays them on the browser.

    Do you know this problem? How do I fix it?

    Great snippet David! This will come very handy for an ongoing project. I’m scratching my head regarding two things 1. the implementation; In the instructions it is mentioned to copy and paste the entire snippet into the theme’s functions.php file. That means even the php opening tag? 2. Would this snippet work with multiple upload files in a form? Exemple adding to the configuration array ‘field_id’ => 5, 22, 35

    Is there a way to have the renaming script pull the ‘value’ instead of the ‘label’ for each of the fields reference in the script?

    The front-end option needs to be descriptive so the person uploading the file has clarity, but the back-end label can be abbreviated to keep filenames short to make life easy for the admin.

      Hi Thad, unfortunately, this is not possible without significant customization. You would need to save two versions of the filename but, by default, GF only allows one value for this field.

Now implementing the same plugin/form on another host – Flywheel – and while the files save as part of the form process, the snippet renaming doesn’t work.

    Is there something I need to check on my Flywheel host that might be keeping this snippet from working?

    So for each upload (multiple forms, multiple upload fields), the number should increment up by 1. This would allow for easy sequencing and finding files after upload. Using Woocommerce and Gravity forms addon to accomplish this. Uploads are for custom art to be added to products.

    David,

    Another very helpful bit of code! One wrinkle: for my use case, cleaning with sanitize_title_with_dashes() wasn’t quite perfect, as it was clobbering case in the value of the selected merge tag. To get around this, I just added a new “uppercase” argument, default false, that would apply strtoupper() before returning from clean(). Since mixed case doesn’t matter for me here, this worked out just right.

    I published my changes here:

      I don’t see why it would have issues on any mobile or other device.

      Hey Erik, pretty sure this is happening in the clean() method. You can overwrite this method with your own like so: http://snippi.com/s/drwp4vh Note that you would now instantiate an instance of your custom class (which extends the base class) when initializing this functionality.

      Then the code is set as active the upload is successful in WP and DropBox but without any name.

      I can provide you with admin access if needed. I believe if we can get the WordPress upload to work the DropBox upload will be correct as well.

      I would add a Hidden field to your form and copy the value from your Reference Code field via the gform_save_field_value filter to the Hidden field with any formatting changes you would like to see. Then use the Hidden field merge tag in the rename template.

      You can actually set the path in the template so long as it’s in the root is the uploads folder. If you’d like us to take a look at your specific filter usage, pick up a copy of Gravity Perks and drop us a line via support.

    Hey David!

    I’m about to put this fabulous snippet into place. (yet another thank you to you!) I have 3 forms, each with a few upload fields. (the forms started as one and were duplicated so several field numbers are the same, in case this looks confusing)

    My forms and their fields are:

    Form 16: Upload fields: 47, 49, 50, 52, 167, 169 Form 18: Upload fields: 47, 49, 50, 52, 167 Form 19: Upload fields: 47, 49, 50, 52

    I’m following along with the tutorial you put here: https://gravitywiz.com/documentation/apply-class-based-snippet-different-forms/

    My question is this: I’m only guessing at the best way to do this, but my thinking is that it’s better coding if I set this up to run through all the different fields within, say, form 18 then move onto the next form and its fields rather than (1) form 18, field 47 (2) form 19, field 47 (3) form 18, field 49 (4) form 19, field 49… etc..

    Or would it matter at all either way?

I tried a static filename also just to be sure it wasn’t an error with the merge tags. are you able to reproduce?

      i am slightly closer to getting this to work, the first issue is that i noticed that is_callable(array( ‘GFFormsModel’, ‘get_phsyical_file_path’) returns false so the code halts before it even gets a chance to do anything. this is because there is a typo on in the method name (s and y the wrong way around)

      ive addressed this and wrapped the GFFormsModel::get_physical_file_path in a function in case it is prone to change (it was in a number of places in your class)

      unfortunately it still doesn’t rename the files as expected but that should make it a bit easier to troubleshoot. my next step will be to look for any more typos, as i had presumed the code provided above had been tested

      David Smith Staff November 19, 2016 at 10:49 am

      Hi Ben, thanks for pointing out the typo. I was actually the person who committed that new method (get_physical_path) to Gravity Forms and I committed it there with the typo as well. Everything was working for a bit because the typo was in GF and the snippet. One of my GF coworkers must of fixed the typo there causing the snippet to break again. I’ve updated the typo here and confirmed that everything is working.

      I also tried with the gform_upload_path and this worked without issue for me. Here’s the exact code I used (code).

    4. ben
      ben November 18, 2016 at 7:53 am

      i can confirm its working now with the typos ammended. i am facing a separate issue now which is that the gform_upload_path_XX filter no longer works (it does work but it negates the file renaming) i assume this is because of the order the hooks.filters are firing. When i try to use your code in conjunction with the upload path filter the files are moved to the correct destination but they keep their original file names. not sure what the workaround for this is as i cant find any ref to the order in which the GF filters and hooks fire

    Hey David – I have a similar question as the person in this last comment. I’d like to take the Last & First names of the person filling out the form (any of the forms on our site) and have a folder created where the files will land. (in my case it’ll be a bucket on S3)

    Please forgive me if it’s in poor taste to link to someone else’s code but I just found this: https://gravitywp.com/tutorial/custom-upload-path-gravity-forms/ I tried hard to find your renaming snippet the person above is talking about but couldn’t locate it.

    Any chance you can pass on a handy little snippet that would do this? Grab info from a certain field or merge tag, go to ‘some-user-defined-spot’ and make a folder there?

    Seriously, if you have something like this kicking around, you’ll be my hero forever.

    Hey David

    Thanks again for another great snippet.

    Just wondering if you have any idea on how to change the upload path as well.

    I’ve tried this snippet of yours that I found but it doesn’t seem to work with the file renaming snippet:

    add_filter( ‘gform_upload_path’, ‘change_upload_path’, 10, 2 ); function change_upload_path( $path_info, $form_id ) { $path_info[‘path’] = ‘/home/public_html/yourdomainfolder/new/path/’; $path_info[‘url’] = ‘http://yourdomainhere.com/new/path/’; return $path_info; }

    Do you have any ideas?

    Hi David, it’s me again, this time I have a problem: I’ve installed the latest version of GF 2.1.0.1 and downloaded your raw code version 1.4, but the renaming doesn’t seem to work. Here is what I uploaded a file named “02logo(1).stl” and click download file button in the gravityview custom content: “wp-content-uploads-gravity_forms-1-7e38ba7731a19dd489bc64977595aeff-2016-11-02logo1.stl” It’s quite a long name, and it’s supposed to be like “ff3dm-02logo(1).stl”, because the template is: ‘template’ => ‘ff3dm-{filename}’ So I’m confused why it’s not working, I have added another snippet “Customizing the Multi-File Merge Tag”, does that affect the output result? Thanks!

      I also installed GF 2.1.0.1 and the renaming does not work anymore. It was working well with GF 2.0.7.15, so GF has changed something that breaks the code… :( Hope David you have an idea on how to resolve this, your code is so useful! :) Thanks,

    This code always seems to go true on the check for GFFormsModel being uncallable. Not sure why. Running lates GF. Weird thing is I’ve seen it work one out of 25 times. :(

    This code is not working on forms created with the latest version of Gravity Forms (2.0.7). I’ve tried it on multiple private sites and it does not rename the file. On forms that were created with previous versions it does work however (2.0.3.5).

    Added the snippet to functions.php, changed the variables under #Configuration, and… nothing. Files are not renamed. Looking through the GF log (GF Plugin Logging Addon), I don’t see any attempt to rename. (Not sure if it should show up there.)

    I’m using merge tags, but also tried with just text appended, and that didn’t work either.

    I’m using custom upload path script as well, and tried removing that as well.

    Here’s the configuration code for this page: http://georgiawatercolorsociety.com/national-exhibition-form/

    new GW_Rename_Uploaded_Files( array( ‘form_id’ => 2, ‘field_id’ => 38, ‘template’ => ‘{Name (Last):1.6}-{Name (First):1.3}-{Title:7}-{filename}’ ) ); new GW_Rename_Uploaded_Files( array( ‘form_id’ => 2, ‘field_id’ => 39, ‘template’ => ‘{Name (Last):1.6}-{Name (First):1.3}-{Title:16}-{filename}’ ) ); new GW_Rename_Uploaded_Files( array( ‘form_id’ => 2, ‘field_id’ => 78, ‘template’ => ‘{Name (Last):1.6}-{Name (First):1.3}-{Title:24}-{filename}’ ) );

    Hello David,

    We are currently only able to access a forms uploaded images after the form entry has been exported to CSV.

    Within the WP admin area, when trying to view the image uploads within each entry, its as if the correct file path hasn’t been written yet. When we try to view the upload it says “image not found”.

    Do you have any idea what might ve wrong?

      I don’t know when it happens, ’cause it is a public form, where people upload their images.

      There is a list of the latest uploaded files: 20160827_193354.jpg Brinotto-di-Anna-3.jpg Brinotto-di-Anna-2.jpg Brinotto-di-Anna-1.jpg IMG-20160630-WA0000.jpg IMG-20160914-WA0001.jpg 10888803_875536422497426_7774155400995582800_n.jpg 20160809_0736000.jpg 20160805_103636.jpg 20160731_200337.jpg

      I’m having a similar issue in that the renaming is not always occurring when the file is uploaded. Seems that the renaming does not take place anymore, except for sporadic occasions where it does work.

      The original filename is maintained unaltered.

      We also have this process linked to a Dropbox upload into a shared folder.

    We’re having an issue where our users are managing to upload empty PDF files. After looking in the gravity forms logs it appears users are getting to page 2 of a 3 page form, uploading the file, than coming back several hours later to submit it. We’re using this script to rename the uploaded PDF file. I was wondering if your script could be causing these empty PDF files. I’m assuming the file in the temp directory is gone by the time the user comes back and your script could be creating a blank file with the new name in the downloads folder.

    The website is an intranet which requires a google login from the companies domain so it’s not easy to share the page with you.

      It seems unlikely. This code is not run until the final submission is being processed. Best way to test is to figure out the exact steps to recreate and then remove the code and see if you can still recreate the issue.

    I’m trying to rename uploaded files but having issue with special characters. For example:

    Visitor would use form to upload their image title, first and last name, and a category so that the image name would end up being:

    Category[Firstname_Lastname]Image_Title.jpg

    But I’m getting:

    CategoryFirstname-LastnameImage-Title.jpg

    It’s stripping the “[” and “]” characters and using dash instead of underscore to replace spaces in image title.

    How can I fix this in the code? The format is very important as the images are ran through another program that requires this format.

      Finally gave up. Tried creating an plugin but the WP version of the sanitize_file_name() method seems to be called first time and I can’t seem to change that. Tried overriding it with a new add_filter in functions.php. No good. Created a plugin that is first in the list (before GF loads) and still no go. I had to resort to simply removing the [ and ] characters from the formatting.php file and make the file immutable (to keep WP from overwriting it for now). Time to move on to other things and come back to this later.

    The dynamic fields are listed in the confirmation email but the file name does not get changed.

    The dynamic filling of the fields happens in gform_pre_submission. Could it be that gform_pre_submission is run after this snippet ?

    Or do you know a solution to get dynamically filled fields into the filename as well ?

      // inside get_template_value $template = str_replace( array(‘{filename}’, ‘{ext}’, ‘{date-ymd}’), array($filename, pathinfo($filename, PATHINFO_EXTENSION), date(‘Y-m-d’)), $template );

      // call to class array element ‘template’ => ‘Resume-{Name (Last):3.6}-{Name (First):3.3}-{date-ymd}.{ext}’

      You can use PHP in the template name when you define it. Example:

      'template' => '{filename}-' . date( 'Y-m-d' )

      This would not strip the 2016 from the middle of the filename per your example but it will append the date to the end of the filename.

    1. David Smith

      Where are you using the multi-file field merge tag? This will largely dictate the format. The issue is that by default, it is provided as a JSON encoded string of the files names. This is where the square brackets are coming from.

    Hello, the snippet is working well!

    However I have a small issue. If anybody uses a forward slash ( / ) in a ‘single line text field’ the renamer truncates the name stopping at the slash.

    EXAMPLE:

    ‘Gordon/Langley’ becomes ‘Langley’ ‘Gordon/Langley/v2’ becomes ‘v2’

    Is there anyway of ignoring the forward slash?

      Hey Gordon, thanks for your patience. We’ve added support for stripping all slashes from the filename before the file is renamed.

      Gordon October 17, 2016 at 7:01 am

      Hey David – I finally added you new code – works great, thanks so much!! I edited it slightly so the forward slash ( / ) is not just deleted but replaced with a dash ( – ).

      function remove_slashes( $value ) { return stripslashes( str_replace( ‘/’, ‘-‘, $value ) );

      Thanks a million!!

    Hi, thank you for your great snippet, it really works wonders, I just have one question though, if I were trying to apply a different renaming profile, how would I do that without having the functions conflicting with each other?

    Any help will be greatly appreciated.

    Hi

    Many thanks for this code i was pointed here from GF Support, this is renaming the file with my desired template style, but i need to access the new file name from with in gform_after_submission hook, is this possible, i have managed to work out to some extent but i am only received the original file name not the updated one?

    Many thanks in advance

      The file is renamed prior to submission (via the gform_pre_submission hook). The $entry passed to the gform_after_submission hook should have the renamed file. Could you send me a [pastie](http://pastie.org] of your custom code?

    Hello

    I can’t figure out a ‘usage example’ that includes all the user input from my form in the file name, renaming the file completely – based on all the user data. Could you explain.

    1. David Smith
      David Smith Staff June 4, 2015 at 6:40 pm

      The idea is that you can use GF merge tags to generate the filename based on the submitted data. In the example above, we have a Name field so we get the first and last name merge tags to generate the file name: {Name (First):1.3}-{Name (Last):1.6}-{filename}. Based on this, could you elaborate on what you don’t understand? I’ll be happy to clarify further.

      Thanks David

      I got it figured… I used this {:1}-{:7}-{:9}-{:8}-{:4}-{:5} and it gave me the results I wanted.

      I have a another question though, do you know how to automatically transfer the uploaded renamed file into the media library. I’ve managed to change the path so the file goes in the upload folder byt I’m having to use the plugin ‘Add from server’ to manually process the file. Many thanks, Gordon

    Hi, I’m using this snippet! thank you very much!

    I would like to set the filename depending on the userID that uploads it. Would that be possible?

    I get the ID using

    $current_user = wp_get_current_user(); $current_user_id = $current_user->ID;

    But i don’t know how to include it into the array.

    Thank you!

      Hi Albert, Gravity Forms supports most user meta (including the user ID) via the {user:prop} merge tag. Try: {user:ID} in your file name template.

    Hi David Smith, Thanks for this nice and helpful snippet. Its really works fine for me. But one great things to be noted that, when i edit an entry and delete older file then upload a new file, it does not rename the file. Its remain in the original file name. Please check it. However your other snippet like date population is working when edit and update an entry. Thanks again.

      Hi Tarequl, you are correct. This only applies to submissions made via the front-end. If enabling this in the back-end proves a popular need, I’ll definitely consider adding support for that. In the meantime, you can manually edit the file name before uploading in the backend.

      I would like to second the request for this to work from the back-end (entry editor) too. I have encountered a use case where this would be extremely helpful.

    This was very helpful for a site I’m working on today.

    Yet, I am having an odd issue and not sure why. When the files gets moved from the directory to the Media Library, for some reason the file name ends up being displayed like “?attachment_id=7089” rather than the actual title. You can see a screenshot of it here, and as you can see, the file title and URL show a full name, but the filename does not.

    At first, I thought it was because your code did not include an explicit reference for the guid in the $attachment, however even after adding it, this value does not update in the database.

    Any ideas?

      Hm, I’m not sure, Adam. This snippet doesn’t move the file to the WP Media Library so there is a chance of a conflict between this snippet and whatever you’re using to do that.

    Two questions. Is this for image uploads or just file uploads? Does this strip trailing spaces. For example someone puts a space after their first name in the field.

    I have problems with new images overwriting old ones with the same file names, the -1 or whatever isn’t appended.

    Thanks!

      Hi Deborah, this is for the File Upload field specifically but may also work with the Post Image field. It does automatically strip spaces. I just tested locally and the auto-incrementer for duplicate file names is working on my end. If you upload images with the same name via WP media uploader, does it auto-increment the name?

    2. Deborah Carney
      Deborah Carney January 7, 2015 at 6:43 am

      The problem I think comes when files are uploaded via different forms and then get dumped into the same folder as other images from other forms. They don’t get the 1 or whatever added on upload. So I end up with image.jpg getting uploaded and overwritten in the year/month directory. Since they get uploaded to a separate GF directory first during image upload or file upload, when they get moved to the general folder it causes issues.

  119. Erik
    Erik December 7, 2014 at 8:02 pm

    Very grateful for this one. This is also useful to help prevent file names from being guessed. For example, under certain conditions (mobile device), Gravity Forms will increment image uploads with file names such as image1.jpg, image2.jpg, image3.jpg, etc. There is no longer a risk of the customer who uploaded image49 manually modifying the file name to see image[1-48], because now I can make the file name more elaborate.
