Our WP Debug is report that 'Function create_function() is deprecated'. Any idea how to rewrite this code to not include create_function ?

 self::register_form_init_scripts( $form, $field_values, $ajax );

            if ( apply_filters( 'gform_init_scripts_footer', false ) ) {
                add_action( 'wp_footer', create_function( '', 'GFFormDisplay::footer_init_scripts(' . $form['id'] . ');' ), 20 );
                add_action( 'gform_preview_footer', create_function( '', 'GFFormDisplay::footer_init_scripts(' . $form['id'] . ');' ) );
            }

• why not just use a anonymous function and call GFFormDisplay::footer_init there? what is the minimum php version you require? – Sisir Commented Sep 17, 2020 at 17:35

You no longer need to use create_function you can instead just use an anonymous function:

add_action( 'gform_preview_footer', create_function( '', 'GFFormDisplay::footer_init_scripts(' . $form['id'] . ');' ) );

Should be:

add_action( 'gform_preview_footer', function() use ($form){
    GFFormDisplay::footer_init_scripts($form['id']);
});
