How to extend a module hook from another module?

Question

I want to be able to clone/replicate a node from one language to another on click of a button using a custom module. Basically we have a view which displays all nodes in the system and under the "operations" column, we have Edit, Delete, Clone.

On click of the Clone button, I want to replicate the node (keeping the same exact data values as is except for the language field) to other languages.

I have installed the node_clone and replicate modules to help me, but I am struggling to see how I can create a custom module that can call the hooks in those contrib modules in such a way that I can save the node in different languages automatically instead of click on the "Translate" tab and manually doing it one by one.

I have tried calling the clone_node_save from the Node clone module from my custom module, but that does not work.

How can I extend a module hook in a custom module?

Answer 1

You can use the following code to solve your problem:

//clone the node
$new = clone $node;
//set the node to new
$new->is_new = true;
//unset the nid and the vid
unset($new->nid);
unset($new->vid);
//setting the new language
$new->language = 'fr';
//save the new node
node_save($new);

Reference: Programmatically create a new node from an existing NID

I assume you're triggering the clone using the "clone item" VBO action provided by the node_clone module? If so, have you looked at hook_clone_node_alter()? It gives you the node (and some context data - see clone_action_clone() in clone.module) and lets you change values before the cloned node is saved.

If you are not using the VBO action, and therefore don't have the hook available, you might want to look at clone_action_clone() and copy the relevant code.

I think you don't need the node clone module. Look at this solution from the comment: https://www.drupal.org/node/1069774#comment-4834192 This is actually utilizing the entity translation module's translation handler. Here is the code again:

<?php

$translation = array(
  'translate' => 0,
  'status' => 1,
  'language' => 'sv', // here is the language you're translating to
  'source' => 'en', // here is the source language
);

$node = node_load($nid); // If you've called node_save($node) before, you'll have the node object already and you can omit this
$handler = entity_translation_get_handler('node', $node);    
$values['name_field']['sv']['0']['value'] = $sv_name; // You can write the array like this, I find it easier to read
$handler->setTranslation($translation, $values);
field_attach_update('node', $node);

?>

Create a module with hook_menu and a page callback that holds the snippet above.
