Custom Post Type Archive in Sub Folder

2 comments

1. Unlike page templates, WordPress doesn’t look in subdirectories for post template pages. The base function used for locating such templates is locate_template() (see source), which looks in the root directory of your theme (and parent theme).

   (On the other hand get_page_templates() searches sub-directory).

   You can use template_include filter (which filters the absolute path to your template) to change the template used:

   add_filter( 'template_include', 'wpse119820_use_different_template' );
   function wpse119820_use_different_template( $template ){
   
      if( is_post_type_archive( 'entry' ) ){
          //"Entry" Post type archive. Find template in sub-dir. Look in child then parent theme
   
          if( $_template = locate_template( 'my-sub-dir/archive-entry.php' ) ){
               //Template found, - use that
               $template = $_template;
          }
      }            
   
   
      return $template;
   }
   

2. As explained by @StephenHarris, the template loader does not do this by default.

   While Stephen’s answer looks fine to me, I was working on one before he posted and it is a bit different. I used the archive_template hook and generated the template name using get_queried_object.

   add_action(
     'archive_template',
     function($template) {
       $path = pathinfo($template);
       if (!empty($path['filename'] && 'archive' === $path['filename']) {
         $pg = get_queried_object();
         if (!empty($pg->name)) {
           $t = locate_template('archive/'.$pg->name.'.php');
           if (!empty($t)) {
             $template = $t;
           }
         }
       }
       return $template;
     }
   );
   

   It is rough code. It may be buggy.
