Support » Plugin: Automatic Featured Image Posts » Not what I expected

  • I am running a photo-blog. I wanted this plugin to grab an image from the post and set it as the featured image. My theme generates thumbnails from the featured image only. So, I have to assign featured image for every post I make.
    This didn’t help me with what I wanted.
    Anyways thank you for the plugin.

  • By the way, I got it worked with this simple script by TOMASZ DZIUDA.

    function auto_featured_image() {
        global $post;
    
        if (!has_post_thumbnail($post->ID)) {
            $attached_image = get_children( "post_parent=$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);
                  }
             }
        }
    }
    // Use it temporary to generate all featured images
    add_action('the_post', 'auto_featured_image');
    // Used for new posts
    add_action('save_post', 'auto_featured_image');
    add_action('draft_to_publish', 'auto_featured_image');
    add_action('new_to_publish', 'auto_featured_image');
    add_action('pending_to_publish', 'auto_featured_image');
    add_action('future_to_publish', 'auto_featured_image');

    This script is very simple – it checks if the specific post has a featured image set and, if the featured image isn’t set, the script checks for the first attached image and sets it as a featured image. This operation is executed for every save or post operation.

    As this instruction is executed on every post displayed, introducing a slight performance hit to your website, they recommend removing the following lines once all the featured images have been generated:

    // Use it temporary to generate all featured images
    add_action(‘the_post’, ‘auto_featured_image’);
