Question

Drupal 6. What is the proper way to execute drupal_add_js only when specific content_type is being created?

I have some jQuery code that needs to execute only to control some form elements in a specific content_type creation.

I already have a module, which has a different name from the content_type. Is this a problem? Can I still hook onto the form? If so, what is the correct way to generate the hook to the specific node/add/content_type?

Edit: this is only needed for the creation, not the view.

Edit 2: code that’s not working at the moment:
file: testmod.module

function testmod_form_node_type_form_alter(&$form, &$form_state) {
   if ($form['#node_type']->type == 'testnode') {
     drupal_add_js(drupal_get_path('module', 'testmod') . '/new_msg.js');
   }
}

Answer 1

There are probably a few ways to do it but I’d use a form_alter hook:

function mymodule_form_node_form_alter(&$form, &$form_state) {
  if (!isset($form['#node']->nid) && $form['#node']->type == 'my-type') {
    drupal_add_js('my-file.js');
  }
}
