    I have a Wordpress theme and I am trying to change how it outputs the post images.

    I am here is my code I am trying in functions.php

    add_filter( 'post_thumbnail_html', 'my_image_func', 10, 7);
function my_image_func($html, $post_id ) {
  $url = wp_get_attachment_url($post_id); // Grab the current image URL
    $html = "<div style='background: url(\"$url\"); ></div>";
    return $html;
  }
    PHP:

    But for some reason $url turns up empty

    Can anyone point me in the right direction on how to fix this?
