Description

Filter the name of the session cookie GPNF uses for a given form

Usage

add_filter( 'gpnf_cookie_name', 'my_custom_function' );

Parameters

• name string

  Default session cookie name GPNF has generated.

• form_id string

  Parent form ID that the nested form belongs to.

Examples

Append Post ID to GPNF cookie name

This example shows how you might use this filter to alter the session cookie name. By default GPNF’s cookies are named gpnf_form_session_xx where xx is the form’s ID. Here we append the post ID as well to ensure that a form could exist on multiple pages with independent child entries.

add_filter( 'gpnf_cookie_name', function ( $name, $form_id ) {
	$id = get_the_ID(); // Get the current ID from WP
	$id = ( $id ) ? $id : url_to_postid( $_SERVER['HTTP_REFERER'] ); // Check referrer for the ID in AJAX calls
	if ( $id ) {
		$name = sprintf( '%s_%s', $name, $id );
	}
	return $name;
}, 10, 2 );

Since

This filter is available since Gravity Forms Nested Forms 1.0-beta-8.68.
