Trigger a module function after a node is saved or updated successfully in the database

Question

I have used this function hook_node_insert() , but it does not help me because this hook runs before the node is actually saved in the database. I am indexing nodes to a third party application whenever a node is inserted, updated or deleted. The application sends request to the node URL, but using hook_node_insert(). It's giving me an invalid document location error because the node is not actually inserted yet.

Is there any hook invoked after a node is saved or updated in the database?

I followed this approach, without success.

function  my_module_node_insert($node) {
  if (!$node->type == 'article' || !$node->type == 'page') { 
    return;
  }
  my_module_do_index($node);
}

You may be able to use Hook Post Action and then use this hook:

function my_module_node_postinsert($node) {
  if(!$node->type == 'article' || !$node->type == 'page' ) 
      return;
  my_module_do_index($node) ; // indexes the node
}

Give it a try and see if it helps!

What you can do then is register a function with Drupal that will get called just about when Drupal is finished with the request. It's actually very simple. You just call drupal_register_shutdown_function() with the name of the function you want to be called. Additionally, you can pass as further arguments whatever it is in your context you want passed to it. It's kinda like subscribing a function to an event.

So now when the request is finishing, we know the node_save() database transaction has completed and we can rely on the data from the database. Using path_load() now will guarantee that the latest path for that node is being loaded.

What you want to use is this function

hook_entity_insert($entity, $type)

This function is called after the hook_node_insert and trigger your my_module_do_index( $node )

Same with the update function use hook_entity_update instead.

Other way to do it could be via hook_cron() and update your index with the cron system.
