First image in post not displaying in post grid

[cmwwebfx]

Here is what I have added to the genesis build I did 2 months ago

function fallback_image() {
global $post, $posts;
  $first_img = '';
  ob_start();
  ob_end_clean();
  $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
  $first_img = $matches[1][0];

  if(empty($first_img)) {
if (preg_match('%(?:youtube(?:-nocookie)?\.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/ ]{11})%i', $post->post_content, $match)) {
    $first_img= 'http://i3.ytimg.com/vi/'.$match[1].'/0.jpg';
}
  //  $first_img = "http://placehold.it/350x150";
  }
  return $first_img;
}

Possibly needs some checking by you first.

Here is my first attempt at cleaning up, but unfortunately it doesn’t seem to work like o our genesis site.

function custom_post_thumb_image($thumb_img_url) {
        if ($thumb_img_url == "") {
         global $post;
        ob_start();
        ob_end_clean();
        $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
        if (!empty($matches) && isset($matches[1][0])) {
        $thumb_img_url = $matches[1][0];
         }
        }
    if(empty($thumb_img_url)) {
if (preg_match('%(?:youtube(?:-nocookie)?\.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/ ]{11})%i', $post->post_content, $match)) {
    $thumb_img_url= 'http://i3.ytimg.com/vi/'.$match[1].'/0.jpg';
}
  }
        return $thumb_img_url;
    }
    add_filter( 'sf_post_thumb_image_url', 'custom_post_thumb_image' );

possibly you might see the issue in the code. Needs fresh eyes I think.

Let me know if you manage to sort it, else I’ll see what I can do for you 🙂
