<p>This plugin adds silent duplicate detection to the popular <a href="http://www.gravityforms.com/" rel="nofollow ugc">Gravity Forms</a> WordPress plugin. The goal is to prevent Gravity Forms from creating multiple entries when an impatient user double-, triple, or full-on secret-combo-move-clicks his/her mouse when submitting a form. No modifications to your forms is necessary, it just works.</p>
<h4>How does it work?</h4>
<p>The plugin prevents duplicate submissions in two ways: first, a small bit of JavaScript is loaded into the page that disables the submit button(s) on form submit. Second, the plugin creates a cryptographic hash of the form data upon submission. This unique hash is compared to a hash stored in a PHP session (if available) and, if a matching hash is found, the form data is altered to simulate a failing honeypot condition. Like with all failed honeypots, Gravity Forms will skip saving the data or sending any notifications but the form will appear (to the user) to have been submitted successfully.</p>
<p>Plugin development can be tracked on the project’s Github Page: <a href="https://github.com/buckii/gravity-forms-duplicate-prevention" rel="nofollow ugc">https://github.com/buckii/gravity-forms-duplicate-prevention</a></p>


Gravity Forms Duplicate Prevention

This is a great plugin! We've had issues with forms that allow users to upload files; if the files were fairly large (and the website was on a slower server) the form would take a bit longer to process.  This plugin helped stop duplicate submissions when the user was getting impatient and pressing the submit button multiple times.  Thanks a bunch!



Great plugin!

This one works now : https://wordpress.org/plugins/gf-prevent-duplicates/

Does not work anymore but...

Silently prevent duplicate Gravity Form submissions.

<p>Provides an Advanced Custom Field which allows a WordPress editorial user or administrator to select a Gravity Form as part of a field group configuration.</p>
<p><strong>This plugin does not have any effect on the frontend of the website. It does not output the form, nor does it modify the output of existing forms. The plugin only adds a custom ACF field type for use in an ACF field group.</strong></p>
<p>Full documentation can be found in the <a href="https://github.com/SayHelloGmbH/acf-gravityforms-add-on/" rel="nofollow ugc">plugin’s GitHub Repository</a>.</p>
<h3>Development</h3>
<p>Version 1.3.2 added a plain HTML filter to the output of the field. This filter is not applied to fields in ACF version 4.</p>
<pre><code>apply_filters('acf-gravityforms-add-on/field_html', string $field_html, array $field, string $field_options, string $multiple)

Advanced Custom Fields: Gravity Forms Add-on

It does what it's supposed to do, and it does it well. A great plugin for selecting a Gravity Form in your ACF fields. Thanks Danny!

Works Perfectly!

Gets the job done

Finally something we can load with Composer. Thank you @DannyvanHolten!

Finally!

For days I’ve been having issues with addons for Gravity Forms where they suddenly stopped showing the fields. Only title and description. The native GF fields worked fine, but any third party ones stopped working. Fields I confirmed were not compatible: Gravity Perks Nested Forms and Slim Image Cropper for Gravity Forms.

I’ve been going through code looking for a solution and googling results. I identified that the fields were not using the right class. They were all using “GF_Field”, the basic class. They should have been using “GF_Field_Nested_Form” for example. The cause was that Gravity Forms was being called too early by this plugin. And that was caching forms before all the plugins have loaded and registered their fields.

There’s a pull request which fixes the problem but it has not been released. That was submitted in 2018. It's the end of 2019 and has not been pushed as a release.

I uninstalled this plugin and replaced the Forms ACF field with a number input where you manually enter the form id. Everything is suddenly working.

Don't combine this plugin with third party GF extensions.
