Targeting specific menu with wp_nav_menu_items

1 Views

Hey! I have added a wp_loginout() to my header using a snippet in my functions.php: 

    add_filter('wp_nav_menu_items', 'add_login_logout_link', 10, 2);
function add_login_logout_link($items, $args) {

        ob_start();
        wp_loginout('index.php');
        $loginoutlink = ob_get_contents();
        ob_end_clean();

        $items .= '<li>'. $loginoutlink .'</li>';

    return $items;
}

The thing is that it shows the login link in every one of my three menues:

    function register_main_menus() {
   register_nav_menus(
      array(
         'primary-menu' => __( 'Primary Menu' ),
         'secondary-menu' => __( 'Secondary Menu' ),
         'footer-menu' => __( 'Footer Menu' ),
      )
   );
};

I would like to target the wp_nav_menu_items filter to only include the login link in the primary menu. Ideas? Thanks in advance

  2. Please modify your code with the following code
    You forgot to add condition if ($args->theme_location == 'primary-menu') this condition check if menu is primary menu or not.

    add_filter('wp_nav_menu_items', 'add_login_logout_link', 10, 2);
function add_login_logout_link($items, $args) {
    if ($args->theme_location == 'primary-menu') {
        ob_start();
        wp_loginout('index.php');
        $loginoutlink = ob_get_contents();
        ob_end_clean();
        $items .= '<li>' . $loginoutlink . '</li>';
        return $items;
    }
}

function register_main_menus() {
   register_nav_menus(
      array(
         'primary-menu' => __( 'Primary Menu' ),
         'secondary-menu' => __( 'Secondary Menu' ),
         'footer-menu' => __( 'Footer Menu' ),
      )
   );
};

  3. Actually, I am fairly new to WordPress development, and am trying to fully understand the documentation.
    I find that there are so many ways to skin a cat, and some are a lot more complicated than others.
    in the case of the above, the probem is solved much easier than previous described;

    add_filter('wp_nav_menu_items', 'add_login_logout_link', 10, 2);

    the wp_nav_menu_items hook is actually dynamic and you can simply add in between wp_nav_menu__items to target the specific menu.
    example;

    add_filter('wp_nav_primary-menu_menu_items', 'add_login_logout_link', 10, 2);

    if you inspect the wp-includes/nav-menu-template.php you can verify this fact.
