   Hi!

   I was reading the doc about conditional tags and decided to add the is_tree() function to my theme. So, as proposed, I added the snippet 4 to my themes functions.php.

   Looks like:
   

   <?php
   
   if ( function_exists('register_sidebars') )
           register_sidebars(2);
   ?>
   function is_tree($pid) {      // $pid = The ID of the page we're looking for pages underneath
   	global $post;         // load details about this page
   	if(is_page()&&($post->post_parent==$pid||is_page($pid)))
                  return true;   // we're at the page or at a sub page
   	else
                  return false;  // we're elsewhere
   };

   But now on the top of my page I see the text of the added function.
   Seems like I added just a textparagraph. Am I missing something?
   Anyone who can explain to me how to add this function properly to my functions.php?

   any help appreciated,
   cya, piedro

   Functions and other PHP code must be INSIDE the <?php and ?> tags. Anything outside those tags is not PHP, it's treated as normal HTML.

   thx otto!

   Things can be so easy. Works now. What a great relief!
   I think the is_tree function should be included anyway - it's just sohandy for conditional designs ...

   thx again,
   cu, piedro
