I'd like this code to only run inside the admin area as it is resorting the items on the public side admin bar too.

  /* Reorder Admin Menu to put "Pages" at the top */
  function menu_order_filter($menu) {
  $content_menu = array('edit.php?post_type=page');
  array_splice($menu, 2, 0, $content_menu);
  return array_unique($menu);
  add_filter('custom_menu_order', create_function('', 'return true;'));
  add_filter('menu_order', 'menu_order_filter');

There is very little overhead to assigning couple of filters on hooks that simply won't fire on front end.

In general it would be something like this:

add_action('init', 'admin_only');

function admin_only() {

    if( !is_admin() )

    // filter assignemnts and such go here

Also create_function() is not recommended for performance and some other reasons. It is better to use more modern Anonymous Functions, but for cases like this WordPress provides ready-made __return_true() function.

  • Sorry i'm more of a copy/paste hacker at the moment. How would i modify my above code to use __return_true()? Thanks. – agileapricot Dec 21 '10 at 13:32
  • @firefusion simply replace create_function('', 'return true;') with '__return_true' – Rarst Dec 21 '10 at 13:38

    You could just hook onto admin_init instead of init and you'll not need that is_admin() check. – t31os Dec 21 '10 at 13:47
  • @t31os yep - that will work too. I just usually have giant wrapper running on init and it is more convenient to keep both admin and non-admin stuff in there. – Rarst Dec 21 '10 at 13:53
  • anonymous functions only work in PHP 5.3+. I'd be curious to know more about the disadvantages of create_function – onetrickpony Dec 21 '10 at 14:09

use the Hook admin_init and later hooks, the init-Hook comes realy ealier as only the admin. But it is important, when you use li18n-functions or AJAX, than it is better you use init.

if ( ! is_admin() ) {
     echo "You are viewing the theme";
} else {
     echo "You are viewing the WordPress Administration Panels";
