Did you know that Gravity Forms supports AJAX? Enabling AJAX means that your forms no longer require a page reload to validate and submit entries.

If you’ve installed Gravity Forms on your website, you may have a number of questions related to AJAX functionality. You may be wondering how to enable AJAX submission and validation for new forms, or you may have encountered an AJAX error, and you’re not sure what to do about it.

We’re going to answer all of these questions (and more) in this post. Keep reading to find out everything you need to know about Gravity Forms AJAX submissions!

What is AJAX?

AJAX stands for Asynchronous JavaScript And XML; it’s a programming technique that allows you to access information from a web server after a page has already loaded.

AJAX allows applications to exchange data with a web server in the background using the built-in XMLHttpRequest object. Using AJAX, it’s possible to update parts of a web page without reloading the entire page.

Enabling AJAX form submission in Gravity Forms is sleek and improves the user experience by not requiring a page refresh.

How to enable Gravity Forms AJAX submission

AJAX is disabled by default on new Gravity Forms. However, you can enable AJAX on new or existing forms in just a few clicks. Here’s how to do it.

Enable AJAX submission on existing forms

The process for enabling AJAX on your existing forms is different depending on which editor you’re using (either the WordPress “Classic” editor or the newer Gutenberg “Block” editor). Let’s take a look at how to enable AJAX for existing forms in both editors.

Enabling Gravity Forms AJAX in the Block Editor

Start by editing the page where your form is embedded. Next, locate the “Gravity Forms” block and click on it to open the Block Settings in the right-hand panel. Now open the “Advanced” settings panel and toggle “AJAX” on.

Enabling AJAX on Forms in the Classic Editor

Still using the WordPress Classic editor? In this case, you’ll need to add a shortcode parameter to enable the AJAX submit functionality.

Start by editing the page where your form is embedded. Now, locate the Gravity Forms shortcode. The shortcode will look something like this (give or take a few parameters):

[gravityform id=”34” title=“true” description=“true”]

To enable AJAX, all you need to do is add ajax=“true” before the closing bracket, like this:

[gravityform id=”34” title=“true” description=“true” ajax=“true”]

That’s it! As you can see, enabling AJAX for existing forms in Gravity Forms is simple. Now let’s take a look at enabling AJAX on new forms when adding them to a page or post.

Enable AJAX submission on new forms

Now let’s look at how to enable AJAX submission when adding a new Gravity Form to a page or post. Once again, the process differs depending on which editor you’re using. 

Block Editor:

Start by navigating to an existing page/post, or simply create a new one. Next, click the ‘+’ icon to add a new block to your page and select the “Gravity Forms” block. If you can’t find it in the block picker, type “Gravity Forms” into the search bar.

After adding the Gravity Forms block to your page layout, select the form you want to embed from the dropdown menu.

Next, open the “Advanced” settings panel on the right and toggle “AJAX” on.

That’s it! Now save the post or page, and you’re done.

Classic Editor:

Start by navigating to an existing page/post, or simply create a new one. Next, click on the “Add Form” button above the editor.

Now, select the form you want to embed from the dropdown menu and check the box that says “Enable AJAX”.

Finally, click “Insert Form” and save your post or page.

As you can see, it’s quick and easy to enable AJAX on new or existing forms! 

Gravity Forms AJAX not working? Here’s what to do

Are you running into problems when trying to submit a Gravity Form using AJAX? It’s not common to encounter errors with AJAX submit, but it can happen due to conflicts or configuration issues with your site or form. Here are a few things that may be causing problems with AJAX submission and how to fix them. 

Check your shortcode for errors 

If your form is embedded using the Gravity Forms shortcode, double check that there are no mistakes, such as a missing double quote, or misspelled words. 

Try disabling Google reCAPTCHA

In the past, Google reCAPTCHA was incompatible with AJAX. Many people would enable reCAPTCHA and then discover that their form wasn’t working properly with AJAX enabled.

This problem was fixed in 2019 when Google released an update that made reCAPTCHA compatible with AJAX. However, it might still be worth disabling it and submitting the form again just to see what happens. If it works when reCAPTCHA is disabled, try using the honeypot field as an alternative anti-spam measure.

Check for JavaScript errors

If Gravity Forms AJAX submit simply isn’t working, check the console for JavaScript errors. If you see an error such as “gform is not defined”, then there’s a high chance that scripts are not being enqueued correctly. This may be due to your theme or plugins causing conflicts.

If you’re not able to debug the issue yourself, enlist the help of a developer or contact Gravity Forms support.

Embed your form using the WordPress editor

If you’ve embedded your forms using a third-party solution, this may cause problems with AJAX submit. Try embedding the form again using the default WordPress editor instead.

Disable caching plugins

If you’re using aggressive caching to speed up your site, this may cause problems with Gravity Forms AJAX submit. Try disabling any caching plugins and testing the form again. If it works, you may need to adjust your caching settings or try a different caching plugin altogether.

Check for plugin or theme conflicts

One of the most common causes of errors in WordPress is different plugins interfering with each other. If none of the solutions above have worked for you, try disabling all plugins except Gravity Forms and switching to one of the default themes. Test your form again and if it works, then you know the problem was due to a plugin or theme conflict.

Gravity Forms AJAX for multi-page forms

Gravity Forms allows you to create multi-page forms (also called multi-step forms). After creating a multi step form, you can embed it on your site and enable AJAX just as you would with a regular form: simply open the block settings, click on the “Advanced” tab and toggle “AJAX” on.

Gravity Forms 2.6 introduces AJAX form saving

With the release of Gravity Forms 2.6 came a new feature – AJAX Form Saving. Now you can save your changes in the form editor without the need for a page refresh! This provides a faster and smoother experience when updating forms.

Here’s a short video clip showing you how it works:
