wordpress plugin GravityForms differenciate limit submissions for the same module in different pages

I'm trying to figure out a way to differenciate the limit submission for a "shared" form on different pages.

If I activate the built in function "limit submissions" in a form (which is shared on different pages) also the submissions limit is shared. I try to explain better

I have 1 form, with let's say 50 limited submissions.
I use this form on page1, page2, page3
10 users go to page1, and submit the form, and nobody submitted anything on page2 or page3 yet. The remaining allowed submissions in page2 and page3 would be 40.

I need to be able to limit submissions according to the specific pages where the form is used, so in this specific case I need to be able to have 40 submissions left on page1, but still 50 left on the other two pages.

Do you have any suggestion on how I can achieve this? Thanks

Solution

You could try adding a hidden field to capture the embed page with the following merge tag in the default value: {embed_url}

Then add this to your functions.php

add_filter( 'gform_get_form_filter_100', 'limit_by_embed_page', 10, 2 );//replace 100 with your form id
function limit_by_embed_page( $form_string, $form ) {
    $page=array("page1","page2","page3");//replace with name of pages where form is embedded
    for($x=0;$x<count($page);$x++){
        $search_criteria[$x] = array(
            'status'        => 'active',
            'field_filters' => array(
                'mode' => 'all',
                array(
                    'key'      => '2',
                    'operator' => 'contains',
                    'value'    => $page[$x]
                )
            )
        );
            
        $entries[$x] = GFAPI::get_entries($form,$search_criteria[$x]);
        $entries_count[$x] = count($entries[$x]);
        if ( $entries_count[$x] > 50 && strpos($_SERVER['REQUEST_URI'], $page[$x]) !== false) {//change 50 to the # of the page limit
            $form_string = '<p>Sorry, the submission limit for this  has been reached.</p>';
        }
    }   
    return $form_string;
}
