Question

I’m trying to understand the difference between hook_node_type and hook_nodeapi

I’ve tried to use hook_node_type with the story node and a simple dsm but got nothing.

function mymod_node_story($op, $info){
   dsm($info);
}

Answer 1

hook_node_type is made to hook into when a node type is changed. Fx if you want to allow comments on node type story etc.

hook_nodeapi is used to be able to hook into the different processes that can happen to an actual node, like when a node is saved, when it’s being viewed etc.

There’s not a hook for specific nodes, but instead you usually do something like this.

function module_nodeapi(&$node, $op, $teaser = NULL, $page = NULL) {
  if ($node->type == 'story') {
    switch ($op) {
      case 'load':
      ...
    }
  }
}
