Drupal: automatically add menu items when new nodes are added

Question

can I automatically add a menu item when I add a node to the page in Drupal?

In other words, can I associate a menu parent with a node content-type, and then automatically add the children if new nodes are added ?

thanks

Answer 1

You can do it with Rules on Drupal 7. This module: http://drupal.org/project/menu_rules adds some actions to rules. One of them is to create a menu item for a node. You select: Event: Create a node | Update a node Condition: Content type is "your content type" Action: Update a menu item for node (there is a checkbox to create the menu item if it doesnt exist)

Answer 2

There's also the Menu Position module that allows to put content under specific menu entries, depending on their content type, their language and taxonomy. It also has a small API to add other criteria.

Answer 3

Yes.

I am sure there is a module do to something like that, but you could also create your own.

There are two ways you could go about it.

You could use hook_menu() to query for the items you want and return the correct menu structure. You would need to also make sure the menu cache is rebuilt on a node save using hook_nodeapi(). See henricks' comments below about why this is a bad idea

Alternitivly you could use hook_nodeapi() to add custom menu items with menu_link_save().

Edit

hook_menu should return an array of menu items, often these are pretty static however there is nothing wrong with these arrays being dynamically generated.

So you can query the node table to get a list of nodes you want, loop through these items and dynamically create an array which contains the correct menu items.

very roughly:

function example_menu() {
  $result = db_query('select * from node where ...'); // put in your own select items and where clause
  $menu = array();
  while ($row = db_fetch_object($result)) {
    $menu['my_path/' . $row->nid;] = array(
      // See hook menu docs for what to put here.
    );
  }
  return $menu;
}
