Add incremental counter in new_rs_slides_renderer_helper

I created some custom variables using new_rs_slides_renderer_helper in a while loop. But as it uses a return, my incremental counter (++$counter) does not work. Is there a way to generate a counter for each gallery image?

    You may use static variable to store index as well as current slider ID (which you can get via $options['id']), similar to how built-in WordPress [gallery] functionality works

    Also, if you're looking for a simple "1 of 10" indicator, you may implement it just via JS

    Hi Dmitry,

    Thanks for the lead! It's an ACF repeater field that I want to add the counter:

    function newrs_add_acf_variable($m, $data, $options) {
    $m->addHelper('gallery_content_description', function() use ($data) {
    $counter = 0;
    while ( have_rows('gallery_content') ) : the_row();
    return ++$counter . get_sub_field('gallery_content_description');
    add_filter('new_rs_slides_renderer_helper','newrs_add_acf_variable', 10, 4);
