Add custom subnav to buddypress userprofile tab \'favorites\'

Oke I stuck with my initial setup in which blogposts are separated from geodirectory. I now made a custom subnav ‘blogposts’ to the ‘favorites’ tab in the following way:

function setup_favorite_blogs_subnav() {

$parent_slug = ‘favorites’;

bp_core_new_subnav_item( array(
‘name’ => ‘Blogs’,
‘slug’ => ‘blogs’,
‘parent_slug’ => $parent_slug,
‘parent_url’ => trailingslashit( bp_loggedin_user_domain() . $parent_slug ) ,
‘screen_function’ => ‘show_my_favorite_blogs’,
));

}

add_action( ‘bp_setup_nav’, ‘setup_favorite_blogs_subnav’ );

function show_my_favorite_blogs() {
add_action( ‘bp_template_title’, ‘subnav_title’ );
add_action( ‘bp_template_content’, ‘subnav_content’ );
bp_core_load_template( apply_filters( ‘bp_core_template_plugin’, ‘members/single/plugins’ ) );
}

function subnav_title() {
echo ‘My favorite posts’;
}

function subnav_content() {
//Present a query here that fetches the user’s favorite blogposts and display them accordingly
}

I put this in my functions.php

Thanks anyways guys!
