1.18.x module.inc module_load_include($type, $module, $name = NULL)
1.17.x module.inc module_load_include($type, $module, $name = NULL)

Loads a module include file.


  // 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 Backdrop to be fully bootstrapped, use require_once BACKDROP_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.

Return value

The name of the included file, if successful; FALSE otherwise.:
