问题
If two modules implement the same hook in Drupal, does the system have a way to define which order the hook functions are called, or is it just luck of the draw/alphabetical ordering? Or something else? Or does my question show I misunderstand hooks in some fundamental way that makes me look dumb?
回答1:
The order is determined based on the weight setting for the module in the system table. If two modules have the same weight, the order is alphabetical.
回答2:
Take a look at module weight in database, or use http://drupal.org/project/moduleweight
