How to set default status to custom post type

1 comment

1. Hook wp_insert_post_data filter to force a post status to be set as incomplete before it can be set as published. With the following code only a post that is set as incomplete can be saved:

   add_filter( 'wp_insert_post_data', 'prevent_post_change', 20, 2 );
   
   function prevent_post_change( $data, $postarr ) {
       if ( ! isset($postarr['ID']) || ! $postarr['ID'] ) return $data;
       if ( $postarr['post_type'] !== 'product' ) return $data; // only for products
       $old = get_post($postarr['ID']); // the post before update
       if (
           $old->post_status !== 'incomplete' &&
           $old->post_status !== 'trash' && // without this post restoring from trash fail
           $data['post_status'] === 'publish' 
       ) {
           // set post to incomplete before being published
           $data['post_status'] = 'incomplete';
       }
       return $data;
   }
