Code

function hierarchical_select_install() {

  // Ensure the Hierarchical Select module runs after the Taxonomy and Content
  // Taxonomy modules! This should not be necessary to do, but apparently some
  // idiot module developer is changing the weight of the Taxonomy module...
  $weight = db_result(db_query("SELECT weight FROM {system} WHERE name = 'taxonomy'"));
  $weight = max($weight, db_result(db_query("SELECT weight FROM {system} WHERE name = 'content_taxonomy'")));

  // Also ensure the Hierarchical Select module runs after the i18ntaxonomy
  // module.
  $weight = max($weight, db_result(db_query("SELECT weight FROM {system} WHERE name = 'i18ntaxonomy'")));

  // Also ensure the Hierarchical Select module runs after the og_vocab module.
  $weight = max($weight, db_result(db_query("SELECT weight FROM {system} WHERE name = 'og_vocab'")));

  // If none of these modules was already enabled, the weight will still be
  // incorrect. Therefore, let's make the minimum weight of Hierarchical
  // Select 15.
  $weight = max($weight, 15);

  // Set the weight one higher than the highest weight we've encountered, so
  // that Hierarchical Select will run after it.
  $weight++;
  db_query("UPDATE {system} SET weight = %d WHERE name  = '%s'", $weight, 'hierarchical_select');
