Hi. I want to take the ID's from a list of repeater images and put them into wordpress standard gallery shortcode:

<?php echo do_shortcode('[gallery ids="194"]');?>

but how do I get each image's ID?

Thanks

Dear Sam,

The image field stores the image URL, so it is not possible to get it directly via get_post_meta. You would have to do it the round way, like this:

function prefix_get_img_ids($post_id) {
 $images = (array) get_post_meta($post_id, 'wpcf-rep-field', false); // cast to array in case there is only one item
 $ids = array();

 global $wpdb;
 
 foreach($images as $img) {
  $query = "SELECT ID FROM {$wpdb->posts} WHERE guid='$img'";
  $id = $wpdb->get_var($query);
  $ids[] = $id;
 }

 return $ids;
}

Please let me know if you are satisfied with my answer and if I can help you with any other questions you might have.

Regards,
Paweł
