Query custom post type only if it contains another custom post type

2 comments

1. I finally found a workaround for this, here it goes :

   I used “get_user” with a “has_custom_post_type” function to query every user with at least one article written and then added the link to their blog CPT by adding “/blog/display_name” in the href.

   Here goes the code

   <?php
   $blog_url = get_bloginfo('home');
   $users_number = 0;
   $blogusers = get_users('orderby=registered&order=DESC');
       foreach ($blogusers as $user) {
        $cpt_count = has_custom_post_type( $user->ID, 'article' );
     if (!empty($cpt_count) ) {
       $users_number ++;
       if ($users_number <= 5) {
         echo '<li><a href="' . $blog_url . '/blog/' . $user->user_nicename . '">Le blog de ' . $user->display_name . '</a></li>';
       }
     }
   }
   ?>
   

   Thanks to everyone for your help.

2. I haven’t tested this, but in my head it works perfectly! What we do is put add a pre_get_posts filter in our functions file then get the current user. IF user isn’t registered, drop out. IF the number of user posts isn’t greater than 0, drop out. IF we’re not on the post type archive, drop out. IF all 3 conditions are true, we’ll replace our default blog articles with the users.

   function user_posts_filter($query){
       $userID = get_current_user_id();
   
       if($userID != 0 && count_user_posts($userID) > 0 && is_post_type_archive('blog')){
           $query->set('post_type', 'articles');
           $query->set('author', $userID);
       }
   }
   add_action('pre_get_posts', 'user_posts_filter');
   

   Hopefully it works for you!
