    Hi, I’m trying to set the last image of any post as featured, actually I have found a php function but it takes the first image of the media library not from my post. I am not a coder, could someone please help me to edit the function so that i can accomplish this?

    function auto_set_featured() {
global $post;
$has_thumb = has_post_thumbnail($post->ID);
if (!$has_thumb)  {
$attached_image = get_children( "post_parent=$post->ID&post_type=attachment&post_mime_type=image&numberposts=1" );
    if ($attached_image) {
        foreach ($attached_image as $attachment_id => $attachment) {
            set_post_thumbnail($post->ID, $attachment_id);
        }
    }
}
}
add_action('the_post', 'auto_set_featured');
add_action('save_post', 'auto_set_featured');
add_action('draft_to_publish', 'auto_set_featured');
add_action('new_to_publish', 'auto_set_featured');
add_action('pending_to_publish', 'auto_set_featured');
add_action('future_to_publish', 'auto_set_featured');

    Thanks for your time

  • Hi @zenitg9
    Although there may be much better way to do this.
    but you try this code.

    
function auto_set_featured() {
	global $post;
	$has_thumb = has_post_thumbnail($post->ID);
	if (!$has_thumb)  {
		$attached_image = get_children( "post_parent=$post->ID&post_type=attachment&post_mime_type=image&numberposts=1" );
		if ($attached_image) {
			$thumb_flag = 0;
			foreach ($attached_image as $attachment_id => $attachment) {
				$attachment_array_size =  sizeof($attached_image);
				// If it is last thumb image of attachment array.
				if( $attachment_array_size == ( $thumb_flag +1) ){
					set_post_thumbnail($post->ID, $attachment_id);
				}
				$thumb_flag++;
			}
		}
	}
}
add_action('the_post', 'auto_set_featured');
add_action('save_post', 'auto_set_featured');
add_action('draft_to_publish', 'auto_set_featured');
add_action('new_to_publish', 'auto_set_featured');
add_action('pending_to_publish', 'auto_set_featured');
add_action('future_to_publish', 'auto_set_featured');
