Every time a new node is published within a single content type, I wish to extract (not remove) all the images out from that node's body and save the URL(s) of the images in the database. I will then use the URLs to make a slideshow of the images on a separate node.

I have three questions:

  1. Which hook runs right before a node is published?
  2. What's the best way of saving those URLs in the database?
  3. Which Drupal function do I use to retrieve those URLs from the database?

Which book runs right before a node is published?

  • hook_node_update($node) The hook is invoked after the node is inserted/updated in the node table

What's the best way of saving those URLs in the database?

  • It totally depends upon your needs, Simply you will have to save in database in your own table(s).

Which Drupal function do I use to retrieve those URLs?

  • For the third question, I meant retrieving the saved URLs from the database. Sorry if I wasn't clear on that. But thanks for the hook and the advice to save them to a separate database - I'll look into that. – john010117 Jun 15 '11 at 16:51

    The first question was before the node is saved so the hook is [hook_node_presave[(api.drupal.org/api/drupal/modules--node--node.api.php/function/…) also, the hook_node_update isn't called while you insert a node. – tostinni Jun 15 '11 at 16:57
