Found this interesting question on the Gravity Forms forum:

I’m selling tickets. So each ticket needs to be associated with a name/email/etc…

Basically, the user needs a way to gather a set of data per ordered product/ticket. My first instinct was to simply recommend using the List field. The user could specify the number of tickets and then add/remove however many rows they need.

I kept thinking on it and realized it would be really nice if the number of List field rows increased/decreased automatically based on the number of selected tickets. Here’s a snippet to do just that!

How do I install this snippet?

Just copy and paste the snippet above into your theme’s functions.php file.

Do I need to modify this snippet to work with my form?

You just need to create your own instance of the GWAutoListFieldRows class. You’ll find two examples at the bottom of the snippet. Comment them out and then add your own! All you need to set is the $form_id, the $list_field_id, and the HTML id of your input as the $input_html_id property.

Looking to make all the rows required? Just use our Require All Columns of List Field Snippet and you should be all set!

      Hi John,

      As you may have seen on the documentation, there is a better way to get this functionality in our GP Auto List Field Perk. Snippet support is also only available to active Gravity Perks license holders and even with that instead of using this snippet, we would recommend using our GP Auto List Field Perk.

      Best,

    Hi, This snippet was working great for us until the GF update to 2.5 and then suddenly it stopped working.

    Luckily for me (since I’m not a programmer), it looks like it was a simple fix. GF changed the ID for the quantity field so instead of using:

    ‘input_html_id’ => ‘#ginput_quantity_240_5’

    The ID name is now:

    ‘input_html_id’ => ‘#input_240_5_1’

    Hopefully this helps someone else. Please let me know if there’s anything else that need to change to keep this snippet working with the new version of GF!

    Hi guys, this looks like a great solution to something I’ve been asked to achieve on a company website. We’re a logistics company looking to create a booking form using GF and we wanted a way for the customer to select a number of pallets to be collected and then for the rows below this to ‘open up’ based on the value selected ie 5 pallets would open up 5 rows to be filled in.

    Is there a way to append a text field before the first input field on a row and then have that text field increase in value as the form becomes longer? Probably not explaining this very well!

    ie someone wants 5 pallets collected, 5 rows are ‘created’ below with each pallet number listed as a pre-filled text field followed by the input fields for that row:

    PLT1 ‘Input Field 1’ ‘Input Field 2’ ‘Input Field 3’ ‘Input Field 4’

    PLT2 ‘Input Field 1’ ‘Input Field 2’ ‘Input Field 3’ ‘Input Field 4’

    PLT3 ‘Input Field 1’ ‘Input Field 2’ ‘Input Field 3’ ‘Input Field 4’

    PLT4 ‘Input Field 1’ ‘Input Field 2’ ‘Input Field 3’ ‘Input Field 4’

    PLT5 ‘Input Field 1’ ‘Input Field 2’ ‘Input Field 3’ ‘Input Field 4’

    Thanks for your time Si

      Hello Zoheir, To make this snippet work, all you need to set is the $form_id, the $list_field_id, and the HTML id of your input as the $input_html_id property. These will be within your personal form. So you forms ID will be the form_id. The field id that contains the list will be the list_field_id and the HTML Field ID on your form will be marked as the input_html_id_property;. Hopefully that clears things up.

      Hi Sarmad,

      We don’t have an exact solution to add a product field into List fields, but a workaround would be to use the Nested Forms to handle this. Basically, you’d create a child form that includes your Drop Down Product field in it, and users can add as many entries to that child form. You may want to check out our documentation on Nested Form and how it works.

      Hello Nicholas, thank you for that information. When using the snippet, You just need to create your own instance of the GWAutoListFieldRows class. You’ll find two examples at the bottom of the snippet. Comment them out and then add your own! All you need to set is the $form_id, the $list_field_id, and the HTML id of your input as the $input_html_id property. // EXAMPLE #1: Number field for the "input_html_id" new GWAutoListFieldRows( array( 'form_id' => 240, 'list_field_id' => 3, 'input_html_id' => '#input_240_4' ) );

      // EXAMPLE #2: Single Product Field's Quantity input as the "input_html_id" new GWAutoListFieldRows( array( 'form_id' => 240, 'list_field_id' => 6, 'input_html_id' => '#ginput_quantity_240_5' ) );

      No need to change the code at the top. If you have a Gravity Perks license we would be more than happy to take a deeper dive into your forms. You could drop us a line through our support channel here. Thanks! 😃

    Reading all the comments about how easy this was to implement, I am feeling a right twit because nothing seems to happen.

    1) I copied the code snippet to my child functions.php file. 2) I removed the leading <!PHP 3) I configured the inputs:

            'form_id'       => 18,
            'input_html_id' => '#input_18_63',
            'list_field_id' => 32
        ) );
    

    Where 32 is the ID of my list field and 63 the ID of my source number field. The source field appears just above the list field.

    The changes to functions.php saved without errors.

    It seems to have exactly NO effect on my form: the list field still displays the +/- buttons and the value entered in the source number field doesn’t change the number of list field rows.

    I’m probably doing or overlooking something very obvious and stupid. I would appreciate any thoughts/help.

    Hi there,

    I noticed there is a dangerous issue with running this using a vanilla quantity field. If a user accidentally (or on purpose for that matter) enters a huge quantity (2000) it will crash the browser as it tries to render 2000 input boxes. The solution is to enable drop down selection on the quantity field or use a JavaScript input mask to limit the input. It might be worth warning people about that.

    I was also trying to use this snippet with https://gravitywiz.com/better-inventory-with-gravity-forms/ but the stock validation doesn’t seem to work when you combine the two snippets. When combined it still lets you select inputs when there isn’t enough stock and you are using two products on one form. When there is no stock the field disables but a user can still use the submission button. When there is no stock you get the out of stock message displayed correctly and the list input is disabled but the total price acts as if you have one item selected and it allows you to continue to submission. I can’t disable the form because there are other products with stock that need to be sold. I’ve tried setting the default value in the quantity field as 0, I’ve tried setting the default selection as zero. I’ve tried to also set the default value of the product field as zero with a php function rather than gravity forms form GUI. But every time it runs out of stock it defaults the value to 1 unit and allows you to submit.

    I don’t know enough about php coding on WordPress to build this from the ground up. My guess is it is something to do with how the list item is first being called. It defaults to one item when the solution to this issue is to set the starting default as zero. I believe there needs to be an amendment to the “Set Number of List Field Rows by Field Value” snippet.

    Hi, I have just discovered that when I include this code in my functions.php, the Parent Page selector disappears in under Page Attributes when editing a Page. It makes no sense since the snippet should only impact the form, not the page editor. The form itself works fine with the snippet.

    I’m wondering if it has anything to do with the (jQuery) call in the function because there was a second snippet that also causes this error and it also included Javascript.

    https://docs.gravityforms.com/making-a-field-read-only/

    Hello, I’m trying to get this to work, but it shows a 404 error. I’m confused about the input_html_id… If my form id is 63 and my number field is 29, should it be:

    ‘input_html_id’ => ‘#input_63_29’

    Or am I missing something? Do I need to add anything to the field itself?

    I’m trying to use this to count the number of rows in my list field so that I can use conditional logic to show file upload fields. I’m using Slim Image Cropper, which doesn’t allow multiple file uploads, so I need to dynamically show these fields based on how many rows there are in a list field. Unfortunately I can’t say “if there are 4 rows, show 4 file upload fields”, so this is my more complicated workaround.

      Sarah June 11, 2019 at 3:44 pm

      Sorry, I couldn’t reply to my previous comment… I’m aware it sets the rows, I just have further plans for it once I get it to work.

      Problem is, I can’t get this to work. I suspect it’s the $input_html_id…

      Using Example 1, if my form id is 63, my list field id is 16, and my number field is 27, should it be:

      new GWAutoListFieldRows( array( ‘form_id’ => 63, ‘list_field_id’ => 16, ‘input_html_id’ => ‘#input_63_27’ ) );

      Using this gives me a 503 Service Unavailable error…

    Hi, Right now I am using this function as you have describe here and it works perfect. The user enters a number in a field and the same number of rows is shown. But how about this. Before number of rows the user select between 4 different settings as radio buttons and this will then create the number of columns the list field will generate.

    Like this: Order shirts for the team!

    Printing: – None – Name – Number – Name and Number

    Number of shirts:

    If the customer choose “Name” and 8 shirts, the list filed shows 2 columns (Name and size (Dropdown) and 8 rows. If the customer choose “Name and Number” and 4 shorts the list field shows 3 columns (Name, number and size (Dropdown) and 4 rows.

    The Dropdown and number of rows is already in place and is working. Any idea about the conditional columns function?

    Hi David,

    Awesome snippet you have here!

    It works well for me, but the problem is that even if I set the min/max for the number input, people are still able to type in any number they went before submission, and if they add 5000 let’s say, the form will then automatically produce 5000 lines… this would take 30-50 sec for my pc to process, on other computers it could take longer or even freeze the browser…

    So is there anyway I could limit the number of rows? For instance, the list would only create 400 rows, no more, even if people type 5000 in the number field…

    Let me know what you think. Thank you!!

    Hi David,

    First off, this is a great snippet and one that’s really helped me out – so thank you!

    However, I have an issue :-(

    When I implement the script, I get the dreaded: Warning: Cannot modify header information – headers already sent by

    Looking at the line in the error, it seems to be from the styles. If I remove that, it then errors again on the closing script tag (line 123)

    I’ve tried two methods to implement this: 1) Directly in the function file and removing the opening <?php tag as per your trouble shooting 2) Setting it as a stand alone file and called in via the functions file

    Any help to fix this would be ace!

    Thanks in advanced

      Hi Ian, this might be a theme/plugin conflict. Are you using WC GF Product Add-ons? If so, it calls the gform_pre_render filter much earlier than expected which is probably what is causing this issue.

      I recommend picking up a copy of Gravity Perks and getting early access to the GP Auto List Field perk. It is a nicer version of this snippet with a super clean UI.

      There are a couple options, both of which are designed to make sure the output_scripts() function is not called before the page is being rendered. The first is to make sure the wp_head action has already been called before outputting the script. The second is to call on the output_script() on a different filter that WC GF Product Add-ons isn’t calling early.

    4. ian
      ian May 17, 2017 at 2:04 pm

      I guess calling before wp_head would be the better/easier option?

    Two questions. 1. Is it possible to make this work with the Drop-Down field type of the Quantity field? Seems to only work if I use the Number field type. 2. If I can only use the Number field type how do I get the up and down arrows to show up like in your example?

    This is a great option. Similarly though it would be useful to have a merge field option that would offer a count of the rows. This eliminates the need for a user qty field. Instead qty is calculated based on the number of rows.

    To add more complexity and offer the solution I am trying to accomplish I would like to get counts based on the values entered into a column. As your example notes I am gathering information for an activity reservation. Part of the refined data I need is the total number of attendees and the number of attendees under 13 years old.

    I am trying to limit form entries based on values entered into a number field in each form. For example, this form is used for event registrations and we need to limit entries based on the numbers attending (each school registration is one entry form). If school A is bringing 8 people and school B is bringing 2 people, we need the form to stop allowing entries once it gets to 300.

    This code is not working correctly. The main/only different between the two forms is the entry field is a quantity and the one I would like to use is a number field.

      Hi Joe, with the current snippet the only way to do this is to specify a hidden field as the “input_html_id” parameter and set the default value of this field to “3”.

      The only issue is that this snippet automatically disables the add/remove buttons for each row. To disable this you can remove line 37.

    Hey David,

    Thanks for posting this snippet. All I needed was the ability to set a minimum number of rows in the list field so I added a number field and hid it with CSS; works better than nothing. :)

    One thing I did notice is that once activated the snippet is throwing the following error:

    Uncaught ReferenceError: jQuery is not defined

    Removing the snippet removes the error.

    Any suggestions on getting that cleared up. Or maybe… just maybe… you’d post a snippet on how to set minimum rows without having to use a number field. Sort of like the option we have already for “Maximum Fields” (wishful thinking).

      Syrehn June 6, 2016 at 5:06 pm

      Hey David,

      Sorry had another question. In theory shouldn’t we be able to comment out line 37 and use css for nth-child to selectively show/hide the + or – for certain rows? Something like :nth-child(-n+4) {display:none;} to hide the selectors for the first 4 rows (assuming we have 5 set rows)?

      I tried testing this and it doesn’t actually work, it hides everything. Is this something to do with how the list field works or how the snippet makes rows load?

      Just curious because it would be awesome to be able to disable the “remove this row” icon on all rows that we are using the snippet to generate (i.e. 5), as well as disable the “add another row” on all rows except the last row we use the snippet to add.

      If we could get something like this to work it would mean that users could add more rows and remove rows those rose but never remove more than we initially set with the hidden field.

    2. David Smith
      David Smith Staff June 6, 2016 at 5:28 pm

      I see the issue with the jQuery is caused by the code not taking AJAX-enabled forms into consideration. This snippet is going to receive a rewrite at some point so I am going to hold off on addressing this until that time.

      You should be able to hide specific rows with CSS. Here’s an example for hiding the 3rd row: .gfield_list_group:nth-child(3) td.gfield_list_icons { display: none }

    3. Syrehn
      Syrehn June 9, 2016 at 3:20 pm

      Hi David,

      Awesome to hear that the snippet will be getting an update at some point. It’s incredibly useful!

      Thanks for posting your CSS, I went back and looked and discovered that I had written it wrong (put the :nth-child in the wrong spot, derp). Working like a charm now. Users can effectively add more rows and remove them but they can’t remove more than the 5 I pre-defined with the snippet. :)

    Hey,

    Thank you very much for the code, works great! I have one issue, I am trying to dynamically pull all product fields from the gravity form and list the fields inside a foreach loop. For the most part this works but it seems to instantiate the listfield ids depending on how many there are on the page. Im assuming this is because the class is being declared inside a foreach loop and it outputs the javascript each time? Below is the code I am using, any help would be great!

    Thanks David for this outstandingly useful snippet of code. I’m coding a golf registration site for a local non-profit radio station and this was perfect for use in numerous areas. I had one form where the team leader could register their team and then choose to send an email out to the other team members telling them to register themselves with their team. Last year, I just used some logic to show up from one to three email fields and then used those to send a form email.

    This year, the new radio station manager wanted to make those emails a little more personal, so I needed to gather the people’s names as well as their email address. So, I figured a list field. But, I needed to have one less than the number of people in their team – they can register a team with less than four and accept others from our registrants. So, if they had three people registering with their team, the leader needed to send out two emails.

    That would have worked great with your previously mentioned modification, but that wouldn’t work here because I was also using the snippet in six or seven other list fields.

    So what did I do? I created a hidden calculated field that took one away from the number in their team and used that field to feed the snippet rather than the actual dropdown. Worked like a charm.

    BTW, thanks David for your help on this tournament last year. That code you wrote that allowed them to choose their team name from a dynamically populated dropdown is working great again this year.

    Cheers mate.

      Awesome, James! Glad I could help. The easiest way to do this is to create to “versions” of the class. You can give the class a different name for your modified version that will handle subtracting one from the count. And then keep the original version for other list fields.

      Hi Lawrence, you can use two stances but the list fields would need to be different. You can use GP Copy Cat to copy the quantity from both fields to a single field so that both fields can effectively update the same list field. Whichever field is modified last will take precedence.

      Hi Harry, the demo is running the latest version of Gravity Forms and appears to be working fine. Yes, you will need the “input_html_id” parameter. It will be the HTML id of whatever input should trigger the row count to change. In the example above it is the ID of the Quantity input.

    What I’m trying to achieve is to have dynamic entry fields so users can personalise their desired product, as the idea is for them to be able to order any number of any given product and be able to personalise each of them with something different.

    Therefore is there a way to make the list fields required and also to limit the number of characters a user can enter into these fields?

    So, the last time I posted I was having problems with a jQuery conflict. I fixed that and all was right with the world.

    Recently my client decided they would rather the purchase order I’m using Gravity Forms for to be able to be added to a shopping cart, so I’ve got the Gravity Forms addon for WooCommerce. I read a comment here about this snippet not working with the WooCommerce quantity field – not sure if that was the only issue with this snippet. I’m not using the WooCommerce quantity field, I’m using the GF quantity field. I actually just installed the WooCommerce addon, and chose the previous form that was working properly as the WooCommerce product. Now, the form displays fine but the list rows do not auto-populate. Looks like the functions are not being called any longer. Do I need to place this script somewhere other than functions.php or modify it in some way?

The option to add new rows for the user disappears as it should, but entering a value into the Single Product Name Quantity field does not auto-populate any rows.

    The code was added from the downloaded code snippet, after watching the video on installation – all done correctly.

      If you’ve already deactivated all other plugins it is most likely a theme issue. You can step through the files of the theme and try disabling them until the error goes away to help pinpoint which file is generating the error. As a first step though, I would just set the theme to a WP default theme to confirm the issue is originating in the current theme.

    Hello, I was wondering if you could help me underatand PHP better from the code above. There is a call to output_script, which is done inside of the prerender function, and the prerender is attached to the add_filter for gform_pre_render.

    The output_script function contains javascript code without being echoed or placed inside of a string.

    I ran a test script to see what this would do:

    Hello World

    with and without the function call to HelloWorld(); The html is only output if HelloWorld is called.

    Why is that not a PHP error? It looks like the html code is ignored, but when wrapped in a function is output only when the function is called. It looks like it is ignoring the text placed outside of the template tags.

    So now that I know that it just outputs the javascript code inline whereever the function is called in the PHP code, it is not obvious to me why that would be executed within a gform_pre_render. How do you know that the gform_pre_render code (output_script javascript code) will output at all in the body of the html document without looking at the context, ie. the gravity forms source code. and what the source intends to do with the raw vanilla javascript. Couldn’t the script be output with the register_init_script hook as well?

    In looking at the register_init_script hook, it seems that it uses the script placed inside of the string and passed off to the GFFormDisplay::add_init_script call.

    Thanks for your help, Masoud

      David Smith Staff July 8, 2015 at 8:16 pm

      Hi Masoud,

      Where the script is output is at least in some part personal preference. By using the gform_pre_render as the hook that then triggers the output_script() method, I know the script will always be output immediately before the form content.

      The gform_pre_render filter will always be called before the form is output because Gravity Forms calls this filter before outputting any form.

      The reason I am about to output the script directly to the page without echoing it or capturing it in a string is because in the function, I exit PHP with a closing PHP tag: ?>. Anything after this tag will be interpreted as raw output and be output to the page immediately.

      At the end of the function, I re-enter PHP with an opening <?php tag.

      Does this help? Happy to expound on any point. :)

    Hi David,

    Almost the snippet I’m looking for. I’d like to keep the field repeatable, but set it up so that it initially displays \maybe 10-12 rows. (That should be enough for most of my customers.) I see that I can use a hidden field to set the number of initial rows, but how do I modify so that the + and – buttons stay and the user can add more fields if necessary?

    Hey this is awesome! One question: is there a way to do this without relying on another field for the input.

    So I just want to set a minimum of 3 list fields without relying on someone selecting 3, or inputting 3 into another box I want the form to start with 3 list fields. I’ve looked around the web and this is the closest thing I can find to something similar. Unfortunately I’m not good enough with php to hack together what I need from your snippet!

      Hi Tony, your comment got lost. Sorry about that. You can try adding a Hidden input to the form with the number of rows you want. It still relies on another field; however, this fact is obfuscated from the user.

    Hi David,

    Thanks for this great snippet. I would love to use it but my situation is slightly different from the examples and I’m not sure how to change it (or if I can).

    On my website the “list row” only appears if there is a quantity set to at least 2 (explanation : if the quantity is set to 1, then it’s a simple contact form. when it’s set to 2 or more, an “additional guest(s) info” list row appears). I would like the number of rows to increase automatically, but it means that for a quantity set to 3, I would only need 2 rows, for 4 : 3 rows, and so on…

    Can I do this with your snippet, and what exactly should I edit in it in order to achieve that ?

    My second question : I would like to add this snippet on all my forms (about 20 of them). Is there a quick and easy way to do that (‘form_id’ => all ??) or do I have to add a snippet for each form with a different form_id each time?

    Thanks in advance, Grace

      Sure think, Kuldeep. You’ll see the “EXAMPLE #1” and “EXAMPLE #2” at the bottom. You only need one of these. Remove the other. On the remaining example, you will…

      1. Update the form_id to the ID of the form that contains your List field.
      2. Update the list_field_id to the ID of the List field on your form. You can find this by hovering over the List field in the form editor (example).
      3. Update the input_html_id to the HTML ID of the field whose value should control how many List field rows are added. The HTML ID will follow this template: #input_{form_id}_{field_id}.

      Does this help?

    Hi David, First, thanks for all the great info on this site. I’m wondering if you have an idea on how to fix my problem. I have an event form, very much like the one used in this demo, but instead of just name and email, I need to gather a lot of other data about the extra attendees too, like job title, phone, etc. The problem is that I can’t get GF to wrap this info onto the next line and all the fields are getting squished together in that one line. Any idea how I can get them to wrap, or a better way to handle these fields? Thanks so much for any advice you can give me!

      Hi Laura, glad you’re finding Gravity Wiz to be a useful resource. It is possible to customize the output of the List field inputs; however, it isn’t super straightforward. There is the gform_column_input_content hook that will allow you to modify the markup of the individual inputs but they’d still be output in the table-based markup which makes styling the List field with CSS very difficult.

      The more comprehensive (and more laborious) hook is the gform_field_content filter. This will allow you to basically rewrite ALL of the markup of the list field.

      Unfortunately, this isn’t a simple solution and will require some trial and error to get right.

    Looking at the screencast again. Yeah it isn’t exactly embedding the child form’s fields directly to the parent form. Some queries: 1. Is it possible to tweak your nested forms plugin so that the inputs are directly embedded? Looks like it allows child form to be filled on pop up after clicking a button. Clearly, the entries are then shown in a table within the parent form.

    1. Say one of the child forms had 30-40 quantity input fields then the parent form will show 30-40 columns based entries right?

    2. Any possibility of rearranging the child form entries within the parent form in a grid format. Would like a grid format of child form entries before the parent form submission stage and after in the final parent form entry view.

      Please let me know how that is possible. I do not have a published URL for the form yet. I believe the the nested form field/feature can do this better instead of the list field? But would need to replicate the nested form based on a number entered, like your demo here. Probably need some clever JS and your handy nested form feature. Please let me know if you still have this. I’m willing to purchase the feature and would greatly appreciate your support on implementing the above.

      It sounds like what you’re wanting to do is “embed” the nested form into the “parent” form. This is not currently possible and presents a number of complications. Gravity Forms will eventually release a field group repeater but until then, the modal nested form approach is the only solution I have.

      Hi David,

      Yeah but your “GP Nested Form” plugin seems to do that right, that is if nesting = embedding? http://www.screencast.com/t/p7sAHutMVfG

      If I replicate a nested form (in the parent form) for the times specified in a number field then I can achieve what I want right? Please let me know if you can provide this. Is the GP Nested Form ready for public now? I could try to use that. Appreciate your helpful responses.

      In regards to embedding the form directly into the parent form, this is not currently possible and presents a number of complications. Gravity Forms will eventually release a field group repeater but until then, the modal nested form approach is the only solution I have.

      The parent form will only show the field data that have been configured to display in the field settings for the Nested Form field. You can opt to show all the fields from the Nested Form; however, this will not look great. Also to be clear, the field input is not shown on the parent form, only the data submitted for that field from the child entry.

      I do have plans to make the Nested Form field output templatable so you could configure how everything displays. For the time being, this is not possible.

      The best way for you to get familiar with what this plugin can do for you is to give it a shot. I’m happy to offer you a 30 day refund so you can give it a try and see if it will work for you. :)

The second one (named a different class) is not being registered and both list fields are running from the same class even though I named them two separate classes. Do I also need to change the name of the function?

      Hi Stephen, what do you mean you named them two separate classes? You should just be able to create two instances of the same class. If you look at the bottom of the snippet code, you will see how I’ve created two instances of the class and just pass different parameters for each instance.

    I’m just playing around with this solution a bit more, and noticed that if the Quantity field is left empty or set to 0, the List field still shows up. In a scenario where you’re selling different ticket types, I think it would make sense to hide those fields until the user inputs 1 or more inside the Quantity field.

    Any ideas on where to start with that? Unfortunately the default conditional logic doesn’t appear to work with Single Products set to Quantity.

    Thanks again!

    1. Corbin
      Corbin January 22, 2014 at 11:39 am

      Looks like I solved the issue. I spoke to Gravity Forms helpdesk and they said that conditional logic is available for separate quantity fields.

      So if you require the List fields to be hidden until something is input, just setup your product field and inside that product field settings set the quantity field to hidden, then add a separate Quantity field (in Pricing Fields), then set the List field to conditional show if Quantity is not null (ie leave value empty). Then just a matter of changing the ‘input_html_id’ in GWAutoListFieldRows().

      Thanks again for this, combined with https://demos.gravitywiz.com/better-pre-submission-confirmation/ this thing purrs like a kitten. Such a great alternative to having to setup a clunky ecommerce plugin.

    This is awesome, and is getting pretty close to something I need badly, which is to allow a user to create an undetermined number of posts from a front end form.  I often use custom post types to customize client sites, and basically I want a way to make each row of of the list field into a custom post type, and potentially make each column cell within the row into a post meta field.

    So as an example, if a user came to a form that let them enter things they had that they wanted to sell, and there were a list field for “phones” that they had to sell, then they could 1) enter the number 3 for how many phones they had to sell, and using this code they would get 3 list field rows, 2) then they enter all the required info in the list field columns (model number, manufacturer, condition, color, etc) and 3) upon submitting the form 3 new posts of the the custom post type “Phones for Sale” would be created (using the custom post type add-on).   I have never quite figured out a good way to do this yet, but I have wanted to do so on at least 4 different projects.  Please let me know if you move in the direction of connecting the list field to post fields or else hacking together repeating groups of post fields.
