无法让'get_the_title'在函数中工作

Question

I've used this in other functions, but it doesn't seem to work in this particular one...

  <?php
      $page = get_the_title();
      $blogusers = get_users('orderby=display_name');
      foreach ($blogusers as $user) {
        $cpt_count = wpse31443_author_has_custom_post_type( $user->ID, $page );

        if (!empty($cpt_count)) {
          echo '<li>' . $user->display_name . '' . $cpt_count1 . '</li>';
        }
      }
    ?>

If I change $page = get_the_title(); to $page = 'title';then it works, so it's something with get_the_title(); but I'm not sure what because it has worked in other functions.

The most common reason why "get_the_title()" wont work is if it is not in "the loop". Make sure that you call the function from within the loop only. If called from elsewhere, you will need to pass the page/post id to the function.
