I'm willing to override a value before it get saved in database. The same value is already overriden by commons_trusted_contacts module using hook_node_presave.

So my custom module hook_node_presave get overriden by commons_trusted_contacts_node_presave.
How do I let drupal know that he need to run my custom hook_node_presave after other hook node presave or to not override that single field value.

Below line being overridden :

$wrapper->group_content_access->set(OG_CONTENT_ACCESS_PUBLIC);

The order of a module's hook invocation is determined by its weight. In Drupal 7 this set in the weight column in the system table.

This can be updated through SQL query by setting your module's weight to the heaviest (last) value.

# Update with the appropriate values for your install
drush sqlq "UPDATE {system} SET weight = [your_preferred_weight] WHERE type = 'module' AND name = '[your_module_name]"'

Or using a module like Modules weight if you need a UI.

See the Drupal.org documentation for more info..

  • Thanks for pointing doc that helped me to come out with the answer bellow by using hook_module_implements_alter. Switching hook order was what I was looking for. – funkyD Sep 7 '16 at 9:40

Thanks for pointing drupal.org documentation, It's was helpfull.

I ended up using hook_module_implements_alter which better suited to my situation than changing the module weight.

So I've changed the order in which my hooks are triggered than changing module weight.

/** * Implements hook_module_implements_alter */ function glue_site_module_implements_alter(&$implementations, $hook) { if (($hook == 'node_presave') && isset($implementations['my_module'])) { //dpm($implementations, 'before'); $module = 'my_module'; $group = array($module => $implementations[$module]); unset($implementations[$module]); $implementations = $implementations + $group; } }

Reading Adjusting module weight: what are the risks and things to look out for? also helped me to understand behavior of changing module weight.
