Hi @ejaganece

I hope you are doing well today.

Could you export your form, upload it to google drive or dropbox and share a link in your next reply?

We would like to test import of that form on our lab site.

Kind Regards,
Kris

Hi @ejaganece

Thank you for sharing the form!

I checked it and the form itself seems fine – there’s nothing wrong with its settings and configuration and appears to be working fine on my end.

What you may try would be to enable “Prevent page caching on form pages” and/or “Load form using AJAX” options in form’s “Behavior” settings as those would help mitigate any duplication issues possibly related to some kind of caching on site or server.

But if that doesn’t help, let me ask additionally:

– are you seeing those multiplied submissions on “Form -> Submissions” page or is it only that you’re getting multiple e-mail notifications about same submissions?

– if it’s the first case – are you absolutely sure that those are multiplied single submissions and not just form submitted multiple times (by user or some bot) with just the same data?

Kind regards,
Adam

Hi @ejaganece,

I hope you are doing well today!

You can use the following code snippet as mu-plugin, just make sure to change “email-1” on line 17 with the name of the field you want to restrict.

You can find more information below on how to use mu-plugins.

Hi @ejaganece

I checked the shared code and it seems that we didn’t notice that it’s actually already a bit old. It’s a custom code and not any official “add-on” (even though made by us) and such codes are not updated often. In this case it seems that due to the changes in the plugin since the code was created, it is no longer correctly working.

I sincerely apologize for our mistake.

That being said, I gave it a shot and came up with a bit simpler code. Please remove the one we’ve shared earlier and instead add this one the same way:

<?php 

add_filter( 'forminator_custom_form_submit_errors', 'check_form_duplicate_submission_data', 99, 3 );
function check_form_duplicate_submission_data( $submit_errors, $form_id, $field_data_array ) {
	
	$form_ids = array( 2245, 123 ); // form IDs - one or more; if more - separate numbers with commas
	$fields_ids = array( 'phone-1' ); // IDs of fields to check, one or more, if more - separate with commas
	
	if ( !in_array( $form_id, $form_ids ) ) {
		return $submit_errors; // just bail out and skip checks
	}
	
	
	foreach( $field_data_array as $key => $value ) {
		$field_name = $value['name'];
		if ( in_array( $field_name, $fields_ids ) ) {
			
			$entries = Forminator_Form_Entry_Model::select_count_entries_by_meta_field( $form_id, $field_name, $value['value'], '*' );
						
		
			if ( $entries ) {
				$submit_errors[][$field_name] = 'Duplicated entry';
			} 
		}
	}

	return $submit_errors;
}

Note that you’ll need to configure form IDs (form ID is the same number you can see in form shortocode) and IDs of fields to be checked in these lines:

$form_ids = array( 2245, 123 ); // form IDs - one or more; if more - separate numbers with commas
$fields_ids = array( 'phone-1' ); // IDs of fields to check, one or more, if more - separate with commas

Here you can also configure custom error message:

$submit_errors[][$field_name] = 'Duplicated entry';

Adam
