Query posts with get_posts( array( ‘post_type’ => ‘services’, ‘post_status’ => ‘publish’ ) ) Loop through the results with foreach and build your select input. Hook into save_post (add_action(‘save_post’, ‘my_save_meta’) to store the selected value (with update_post_meta).
Because the credit data is saved in the attachment’s post meta, not the main post: $credit = get_post_meta( $post->ID /* Wrong ID! */, ‘credit’, true ); Instead you need to catch the ID of the inserted image: function attach_image_credit( $images ) { $return = $images[0]; // Get the image ID from the unique class added … Read more
You got it quite right, but with a few minor problems. First, please use a uniqe prefix for your functions and values – opacity or meta_save are quite generic and could be used by other authors. Second, the part where you get the meta opacity was missing, I added it for you – just retrieve … Read more

So after @Nicolai found that blurb in the WP source confirming that I can’t use multiple parameters in the orderby if I am ordering by relevance I had to go a different route. However, this route only works if I don’t care for pagination. There probably is a way to put it back, but I’m … Read more
the simple solution would be to paste this snippet of code in your theme’s functions.php file : add_action(‘wp_head’,’keywords_and_desc’); function keywords_and_desc(){ global $post; if (is_single()||is_page()){ if(get_post_meta($post->ID,’my_keywords’,true) != ”) echo ‘<meta content=”‘.get_post_meta($post->ID,’my_keywords’,true).'” name=”keywords”>’; if(get_post_meta($post->ID,’my_description’,true) != ”) echo ‘<meta content=”‘.get_post_meta($post->ID,’my_description’,true).'” name=”description”>’; } } And the just add keywords and description using the built in custom fields on a … Read more
