Loads a module include file.
Examples:
// Load node.admin.inc from the node module.
module_load_include('inc', 'node', 'node.admin');
// Load content_types.inc from the node module.
module_load_include('inc', 'node', 'content_types');
Do not use this function to load an install file, use module_load_install() instead. Do not use this function in a global context since it requires Drupal to be fully bootstrapped, use require_once DRUPAL_ROOT . '/path/file' instead.
$type: The include file's type (file extension).
$module: The module to which the include file belongs.
$name: (optional) The base file name (without the $type extension). If omitted, $module is used; i.e., resulting in "$module.$type" by default.
The name of the included file, if successful; FALSE otherwise.
function module_load_include($type, $module, $name = NULL) {
if (!isset($name)) {
$name = $module;
}
if (function_exists('drupal_get_path')) {
$file = DRUPAL_ROOT . '/' . drupal_get_path('module', $module) . "/{$name}.{$type}";
if (is_file($file)) {
require_once $file;
return $file;
}
}
return FALSE;
