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.
<h4>How does it work?</h4>
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.
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>

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/
Thanks anyway

Does not work anymore but...

Silently prevent duplicate Gravity Form submissions.

GravityWP

Visit <a href="https://gravitywp.com/docs/count/" rel="nofollow ugc">GravityWP.com</a> for documentation.
Most simple version of the shortcode (Count and display the number of entries Gravity Forms for a form):
<pre><code>[gravitywp_count formid='']
</code></pre>
Or when you want the total of the values of a number field (display the sum of the values of a number field for all entries a specific Gravity Form):
<pre><code>[gravitywp_count formid='' number_field='']
</code></pre>
The most extensive version of the shortcode (display the total value of a number field from multiple Gravity Forms entries with up to five filters and input for number of decimals, the decimal point notation and the thousand seperator, etc, etc):
<pre><code>[gravitywp_count formid='' formstatus='' number_field='' filter_mode='' filter_field='' filter_operator='' filter_value='' filter_operator2='' filter_field2='' filter_value2='' filter_field3='' filter_operator3='' filter_value3='' filter_field4='' filter_operator4='' filter_value4='' filter_field4='' filter_operator4='' filter_value4='' decimals='' dec_point='' thousands_sep='' is_read='yes' is_approved='yes' is_starred='no' created_by='1' multiply='2' start_date='12/31/2016' end_date='12/31/2017' workflow_step='' workflow_step_status='complete' workflow_step_is_current='true']

GravityWP – Count

This is the first time we developed a freely available plugin on WordPress.org and we are amazed by the very positive comments we got. We developed the plugin because a lot of our clients asked for it, and decided (in the philosophy of Matt) to spend 5% of our time on developing code for the community. We are satisfied by the results thus far, but could really use all the positive feedback and suggestions we could get.

Plugin

Count, filter and display the number of Gravity Forms entries or the total of a number field for multiple entries.
