Menu local tasks and hook preprocess

Question

I just want to remove a secondary menu local task from a preprocess function such as

function mymodule_preprocess_menu_local_tasks(&$vars, $hooks) { 
    $vars['secondary'] = '';
}

I'm using D7, sky theme for front-end and seven theme for admin. The above code works in seven but not in sky.

The sky theme page.tpl.php has a variable $secondary_local_tasks which I might be able to remove from hook_preprocess_page(). I also tried this :

function mymodule_preprocess_page(&$vars, $hooks) { 
    $vars['secondary_local_tasks'] = '';
    unset($vars['tabs']['#secondary']);
}

My hook is invoked correctly, but the secondary local task is still rendered to the template. Where local tasks are prepared to be rendered after my hook ?

Answer 1

Finally, I've done with hook_process_page() and removed the variable secondary_local_tasks upon logged-in user role before rendering to the template.

function mymodule_process_page(&$vars, $hooks){
    global $user;
    if(array_key_exists(6, $user->roles) && arg(0) == 'user' && arg(2) == 'edit'){
        $vars['tabs']['#secondary'] = array();
        if(isset($vars['secondary_local_tasks'])){
            $vars['secondary_local_tasks'] = array();
        }
    }
}

I have also tried this from hook_preprocess_page(), but it did not work on the sky theme.

Or use: hook_menu_local_tasks_alter()

Answer 3

You could use hook_menu_alter to remove any menu entry. This would be completely indipendent of the theme.

Just implement hook_menu_alter in a custom module and look at the given menu items with a dubugger or dpm(). Then do something like this:

unset($items['menu/item/to/delete'];
