   Hi,

   I try to retrieve the content before the <!--more--> tag of a page.

   I use a custom query and I created a specific function in my functions.php file.

   Here is my custom query in my index.php page

   <?php
   		$arg = array('post_type'=>'page','post_parent'=>5, 'showposts'=>1, 'orderby'=>'rand', 'post__not_in'=>array(36));
   		$randomService = new WP_Query($arg);
   			while($randomService->have_posts()) : $randomService->the_post();
   		?>
   <!-- this is the function supposed to display the stuff -->
   <?php the_page_excerpt(150); ?>
   
   <?php endwhile; ?>

   and this is the function in my functions.php file

   function the_page_excerpt($length) {
   	global $more;
   	if ($pos=strpos($post->post_content, '<!--more-->')) { $more = 0; the_content(''); }
   	else { $page_excerpt = $post->post_content; echo substr(strip_tags($page_excerpt),0,$length).'&nbsp;...'; }
   }

   But nothing displays... and if I add these lines in my index.php:

   global $more;
   	if ($pos=strpos($post->post_content, '<!--more-->')) { $more = 0; the_content(''); }
   	else { $page_excerpt = $post->post_content; echo substr(strip_tags($page_excerpt),0,200).'&nbsp;...'; }

   It works...

   So, what is wrong with the function in my functions.php file?

   Thanks a lot for your help!

   did you put the functions.php code at the very top?

   Thanks for your response.

   I tried to put my code at the very top of the functions.php file but it changes nothing.

   Any idea is welcome!
