Stop! There's a better way.

This snippet is available as a plugin with Gravity Perks, a suite of over 33 premium Gravity Forms plugins!

Are you interested in adding a quick pre-submission confirmation page to your forms where users can preview their entered data before it is submitted? Gravity Forms does not provide any way to do this by default; however, with a bit of custom code and a few simple form configuration instructions, you’ll have pre-submission confirmations working like magic!

One of the big things missing from the our old Simple Pre-submission Confirmation Snippet was support for Gravity Form merge tags. With some recent changes to Gravity Forms, supporting this in HTML fields became a lot easier.

  1. The Code
  2. The Form

Let’s dig in!

Step 1: The Code

The following code can be copied and pasted into your theme’s functions.php file.

This code provides the ability to use Gravity Form merge tags in an HTML field on the final page of your form, allowing users to preview their data before submission. Since you can now use merge tags, there is no need for the old shortcode method from the previous version of this snippet.

Step 2: The Form

With the code in place, it’s time to configure the form. The first thing we’ll need to do is add a page at the end of the form for the pre-submission confirmation. You can do this using the Page Break field type.

Next add an HTML field from the “Standard Fields” section. I renamed my HTML field “Confirmation”. Your page should now look something like this:

Pre-submission Confirmation Page Configuration

Go ahead and select the HTML field for editing. The “Content” setting of this field now supports all merge tags like {Name (First):4}, {Question:5}, and even more advanced merge tags like {all_fields}. How about that!

You can see exactly what this content generates by submitting the demo form here.

The previous version of this snippet allowed you to put content inside a [gform_preview] shortcode and only display that content if a specified value exists. We’ve dropped support for that in favor of using Gravity Forms default conditional shortcode

Summary

Let me know how this new code works out for you!

The Saved Forms add-on by soulseekah has been updated to work with this snippet. Make sure you get the latest version of the Saved Forms add-on.

    Hi, This is exactly what I was looking for but I have a few questions. I have a build your own gift box form and I am using this so the customer can preview all the products they have selected before they add to cart.

    1 – Can its how each products price and the total at the bottom. At the moment it is only showing total price. 2 – Can a customer edit their products, delete some and then the option to add more. 3 – How can I edit the style of the form to look like my Product page? I have used the same Custom CSS Class as the Product page but is not changing the look of it.

      Hi Brenda,

      1) You should be able to do this with our GP eCommerce field Perks and some customization to the Order Summary markup snippet.
      2) No, it’s currently not possible for a user to edit the field values on the Preview Submission page. To edit the values, a user will have to navigate back to the page with the value they want to change.
      3) You may want to check out this documentation from Gravity forms on editing the style and designs: https://docs.gravityforms.com/design-overview/

      Best,

    • Brenda says

      1 – I tried this and it caused my site to shut down so I clearly do not have the proper knowledge for this. Is there anywhere I can get the exact process to add the amount of each product in the summary?

      2 – I then need to add this to the form saying ‘Please press pervious in the bottom right hand corner, this will bring you back to the product page where you can deselect and change your products choice’. Can you let me know how I can add that?

      3- I add the css that I used on the product page but it didn’t change any of the design of it.

    • Samuel Bassah says

      Hi Brenda,

      1) Please refer to our article on snippet troubleshooting for details on installing our snippets.
      2) You can add the text within an HTML field on the last page of the form. The same page as the HTML field that has the all_fields merge tag.
      3) Here is an article on how to add CSS to a WordPress Website. If you’re a Gravity Perk License holder, you can get in touch with us via support form so we can take a closer look at your setup and assist you further.

      Best,

    Hello, I have a Gravity forms with a lot of fields and I would like to display a specific field on a specific page of my website. For example : on my home page : I would liket to display field number 1, 2 and 3 (ID field) and on an another page I would like to display only the field with ID 7. I tried this shortcode : [gravityform id="1" title="false" description="false" ajax="true" tabindex="1" field_values="check=First Choice,Second Choice" field_id=7] but it is not working. Any idea ? Thank you so much for you rhelp

  3. ANTONIS T. says

    Hi David, i want to use this nice plugin. i want το customize the preview by using the individual field merge tags. Μy guestion is , is it possible, the preview not to be all in one line. I want like a letter, with spaces between the field merge tags, and is some cases to be in one line down. (such as thanks/apology letter for example) I will not use labels

    thank a lot Antonis

    • David Smith says

      Hi Antonis, if you’re using the individual merge tags, you will need to use HTML

      <

      p> and
      tags to add space between the fields as desired.

    • ANTONIS T. says

      thanks for your help i really appreciate, one more question…very important for the form i want to create with gravity…

      the Submission Preview is it possible to be in the same page with the fileds, and not in a separate page? so the users dont have do press button for next page (in order to make changes in the forms) .

  4. Daniel Lott says

    Hi David I have a long complicated form with various fields being displayed depending on what the user has input in other fields etc. Some of the these hidden fields have default values in. How can I preview ONLY the fields that are visible? Ive tried the snippet you linked to but that didnt work. Thanks

    Hi on my review page (which looks great now thanks) the customer only wants certain sections i.e. the customers personal details to be shown I am using a paged form how do i go about doing this thanks in advance Alistair

    Reply

    • David Smith says

      Hi Alistair, you can customize your preview by using the individual field merge tags rather than the {all_fields} merge tag. Alternately, you can customize the {all_fields} markup and exclude specific fields via the All Fields Template plugin.

    • Alistair Mckenzie says

      Thanks David, I’am slowly getting there with the below, I presume I need to wrap in divs or spans so i can style manually but the main thing is how do i tell it if the field is empty don’t show

      Name: {Name:6.3}, {Name:6.6}, Date of Birth: {Date of Birth:7}, Sex: {Sex:5}, Marital Status: {Marital Status:8}, Email: {Email:10}, Telephone: {Telephone:11}, Address: {Address:37.1}, {Address:37.2}, {Address:37.3}, {Address:37.4}, {Address:37.5}

    I am using this addon for my submissions page, and it works great, but one small issue I have is when listing the merge tags in the HTML block in a list format, there are gaps where the merge tags that were not selected are.

    My temporary fix is placing each merge tag in its own HTML block, and setting the visibility conditions accordingly. But this is preventing me from placing a “Copy To Clipboard” button on the summary page

    Hi there, i’ve been using this for a long time, and it worked great!!

    but now it seems to be broken with gravity forms 2.3! (https://www.gravityforms.com/gravity-forms-v2-3-released/)

    –> the submit and back buttons don’t seem to work anymore, nothing happens when i click on them.

    do you experience the same problems with gravity 2.3? or should it be working? would be great if you can help.

    greetings from austria

    Hello. I’m not sure of the correct terminology, but I’m trying this snippet and I’m experiencing a difficulty: When I use a field with a sub-value, the pre-submission confirmation shows the entire field. For example I’m trying this:

    “Hello, how’s the weather in {Address (City):4.3}?” Which should return the info from Address Field Value 4, sub-value 3 (City):

    “Hello, how’s the weather in Portland?

    But what I’m getting is this:

    “Hello, how’s the weather in 123 1st St, Portland, OR 97086, USA?”

    So it’s displaying the entire contents of the Address field. Any idea on how to fix this?

    Thanks.

    Hi I’m using your snippet to make a pretty pre-submission page. Everything works fine, but when using a “Option field” it won’t display value AND price in notification mail when the order has been submitted. Please take a look here: https://prnt.sc/gjoyk3 It does display the value and price on the pre-submission page but I would like to transfer these values to mail as well. Can you help me doing that? Thanks Andreas
