   Instead of adding the custom field at the time of creating the post, how do I display a custom field by default on the admin page?

     If you notice, the code above doesn’t have anything related to the custom post types. It only adds to Post and Page „content type”. So you would have to specify the hook for your custom post type.

       Thanks for the reply. Can you help me out on this code.
       add_action(’publish_page’, 'add_custom_field_automatically’);
       add_action(’publish_post’, 'add_custom_field_automatically’);
       add_action( 'save_post’, 'add_custom_field_automatically’ );

       function add_custom_field_automatically($post_ID) {
       global $post;
       if(!wp_is_post_revision($post_ID)) {
       global $wpdb;
       $user_id = $wpdb->get_var("SELECT post_author FROM $wpdb->posts WHERE ID = $post_ID");
       $themename = $wpdb->get_var("SELECT meta_value FROM $wpdb->usermeta WHERE meta_key = 'themeperauthor’ AND user_id = $user_id");
       add_post_meta($post_ID, 'themeperauthor’, $themename, true);
       }
       }
       When the user meta field is changed, I want to automatically delete the custom field value and update with the new one

   I’ve been working on adding some hidden custom fields on post publish/update (by preceding the field name with „_”) but for some reason I have to update the post twice before the wp_postmeta entries are written to the database.

   I’ve tried messing with the priority and experimenting with other action hooks (draft_to_publish, edit_post, etc) but it doesn’t seem to make a difference.

   Any ideas?

   will this work too for custom post types?
   sth like add_action(’publish_custom-post-typ-name’, 'add_custom_field_automatically’);

     Yes, it will.

     One downside to this technique that people should be aware of is that if somebody edits a published post, this hook WILL get fired again on the edit. Therefore, you need to check for the meta before adding it, or to update it, or to do whatever makes the most sense for your use-case.

     If you only want to get your code fired off on the initial publish only, then you can use the transition_post_status hook. This hook works like this:

     
add_action('transition_post_status','example',10,3);
function example($new, $old, $post) {
// $new is the new post status ('publish')
// $old is the old post status ('draft')
// $post is the complete Post Object (so use $post->ID for the ID, etc)
}


     Then, in here you can do a check for something like this:
     
if ($new == 'publish' && $old != 'publish')


     To have your code only used when the post status actually transitions to publish from whatever it was before. This hook is fired at the same time as the {$status}_{$post-type} hooks are, so the operation of them is basically the same.
