drupal_alter() example
Tue, 08/03/2011 - 11:49 — egyember
This is a quick article about the drupal_alter() function using pathauto as an example.
In pathauto.inc, there is a drupal_alter('pathauto_alias', $alias, $context) call, so we can implement our own function to alter the alias generated by pathauto.
In our example module we need to create a new function, where the first part of the function name is the module name, "example_module", the second part is the string, "pathauto_alias", used in the drupal_alert call and the third part is the hook name, "alter". Arguments are (for Drupal 6) $data and $context.
/**
* Implementing drupal_alter() hook to override pathauto alias
*/
function example_module_pathauto_alias_alter($data, $context){
// you can do stuff with the data. No return required as $data is passed in by reference.
}
That's it. It is not very complicated. :)
