Questions tagged [drupal-alter]

drupal_alter() is a function that allows modules to alter the data structures used by other modules.

The function is used to invoke the implementation of hook_$type_alter() made from other modules. Such hooks are used to allow third-party modules to alter the data used by a module, and they should replace the custom hooks before used on Drupal 5, where drupal_alter() was not used.
