Question

I’m creating a module that let’s your users add feeds.
So i want my code to provide tabs that can be overwritten at the theme layer.

I thought this could be done with the hook_menu:

$items['tab_add_feed'] = array(
  'title' => 'Add Feed',
  'page callback' => 'xml_parser_add_feed',
  'access callback' => 'user_access',
  'access arguments' => array('manage own feeds'),
  'type' => MENU_LOCAL_TASK,
);

something like the above.
But I’m using it on the front side of the site.

How can i add tabs or links on top of my page the drupal way?

//edit

There are none tabs present at the moment, maybe i have to make them visible?

fixed it by adding <a href="xml_parser/add_feed">add feed</a> to the main page callback function
But this is ugly, hard coded and not theme-able. waiting for a better solution.

//edit

This is the code i am using now

function xml_parser_menu() {
    $items = array();

    $items['xml_parser'] = array(
            'path' => 'xml_parser',
            'title' => t('Feed'),
            'description' => t('Add/edit feeds'),
            'page callback' => 'xml_parser_manage_overview', 
            'access callback' => 'user_access', // get user access
            'access arguments' => array('manage own feeds'), // check user if premission is set
            'type' => MENU_NORMAL_ITEM,
            'menu_name' => 'primary-links', // add to primary menu
    );

    $items['xml_parser/add_feed'] = array(
            'path' => 'xml_parser/add_feed',
            'title' => 'Add Feed',
            'page callback' => 'xml_parser_add_feed',
            'access callback' => 'user_access',
            'access arguments' => array('manage own feeds'),
            //'access' => user_access('maintain own subscriptions'),
            'type' => MENU_LOCAL_TASK,
    );
    return $items;
}

I think the name of the item would be something like ‘user/%/add_feed’, with the % argument being the user id. Also, the access callback is spelled incorrectly, should be user_access. This should create a tab for a user on the user profile page. You could also do node/%/add_feed to add a tab to a node.

While developing this module, you may find it useful to also use this:

function mymodule_init() {
   cache_clear_all();
   menu_router_build();
}

Until you get the menu straight.

If you want to just add an arbitrary tab to a page to add a feed, it would probably be an autonomous menu or a themed link. I would need to know more about the context of the feeds you are trying to provide and how users are subscribing.
