Example:

elgg_unregister_page_handler('friends', 'friends_page_handler');
elgg_unregister_page_handler('friendsof', 'friends_page_handler');

elgg_register_page_handler('editors','theme_editors_page_handler');

 

function theme_editors_page_handler($segments, $handler) {
    elgg_set_context('editors');
    
    if (isset($segments[0]) && $user = get_user_by_username($segments[0])) {
        elgg_set_page_owner_guid($user->getGUID());
    }
    if (elgg_get_logged_in_user_guid() == elgg_get_page_owner_guid()) {
        collections_submenu_items();
    }

    switch ($handler) {
        case 'editors':
            require_once(dirname(dirname(dirname(__FILE__))) . "/pages/friends/index.php");
            break;
        default:
            return false;
    }
    return true;
}

Ok, thanks to both of you.

I did it exactly like you have suggested it. But my handler is routed to the home page. I suppose that something is wrong with the place I have stored the index.php. I put it to '/mod/myplugin/pages/friends/index.php'. And no matter if I am writing:

require_once(dirname(dirname(dirname(__FILE__))) . "/pages/friends/index.php");

or

require_once(elgg_get_plugins_path() . "myplugin/pages/friends/index.php");

It doesn't route to my index.php. Any hints?

I found the bug. It was the usual copy & paste error. ;-)

I copied parts of the code from the original friends_page_handler() function in /engine/lib/users.php, but used in my plugin_friends_page_handler() function another name for the parameter $segments.

Now it works fine.

Thanks again for your help.

It really depends what the users will be doing, but in my experience, database costs are minimal. If you're doing lots of file uploads, pictures, etc, that would end up taking more space really fast.
