Assure hooks in a Drupal module are ran before the others.

 / Published in: PHP
 

Sets a module's weight to the lowest number. This assures that your module is ran before all other modules. Userfull if you want your implementation of a hook to be ran first. Add this to your .install file. Replace your_modulename with the name of your module.

  1. function your_modulename_install() {
  2.   switch ($GLOBALS['db_type']) {
  3.     case 'mysql':
  4.     case 'mysqli':
  5.       $weight = db_result(db_query('SELECT MIN(weight) AS weight FROM {system} WHERE status = 1')) - 1;
  6.       db_query("UPDATE {system} SET weight = %d WHERE name  = '%s'", $weight, 'your_modulename');
  7.     break;
  8.     default:
  9.       drupal_set_message(t('Your database type is not supported'));
  10.   }

Nice. How about making sure it's the last one run (warning: untested): $weight = dbresult(dbquery('SELECT MAX(weight) AS weight FROM SYSTEM WHERE status = 1')) +1;

Your db_query syntax is not quite right. "SYSTEM" instead of "{system}". "weight = %s" instead of "weight = %d".

@wimLeers: correct. I've corrected this.

@oadaeh, that is about it. If I need a module to run last, and therefore developed that code, i'll submit it on this site :)
