Define administrative paths.
Modules may specify whether or not the paths they define in hook_menu() are to be considered administrative. Other modules may use this information to display those pages differently (e.g. in a modal overlay, or in a different theme).
To change the administrative status of menu items defined in another module's hook_menu(), modules should implement hook_admin_paths_alter().
An associative array. For each item, the key is the path in question, in a format acceptable to drupal_match_path(). The value for each item should be TRUE (for paths considered administrative) or FALSE (for non- administrative paths).
Note: this list is generated by pattern matching, so it may include some functions that are not actually implementations of this hook.
function hook_admin_paths() {
$paths = array(
'mymodule/*/add' => TRUE,
'mymodule/*/edit' => TRUE,
);
return $paths;
}
