I am creating a module for users to register for an organization, and am using profile.module as a reference, but I am not sure exactly how they are using hook_user(). In profile_user(), there is a switch statement that calls different other functions depending on the value of $type. These functions are profile_load_profile(), profile_form_profile(), profile_save_profile(), profile_view_profile(), profile_validate_profile(), and profile_categories(). Many of these functions are similar to hooks (such as hook_validate() and hook_form()).

In drupal can anyone tell me how to exclude a node type from the search indexing?

I have read that there is a way in 4.7. Can anyone tell me how? This would be for a custom module.

Thanks...

Thanks very much!

I've installed an epublish module.
I've included stories, pages etc. in the edition.

Now i want a index type of layout wherein i first want to list topics (included in the edition of the publication) based on the category. Clicking on the topic should take the user to detail/abstract that follows index. I've 5 categories that i want to display.

I was able to create index layout by adding new layout.inc file in the epublish folder but i could not group the listing into categories.

How can I achieve this? Can anyone help?

Hi,
I've created a custom node type and I'd like to add another tab to the ones that the admin sees (view & edit).
I gather you use something like:

$items[] = array(
      'path' => 'admin/user/create/retailer',
      'title' => 'add user',
      'callback' => 'search_view',
      'type' => MENU_LOCAL_TASK);

in your node_menu, but I can't get it to work.
Could anyone help? There seems to be no documentation on this.
Cheers,
Toby
