[SOLVED] IT DOES NOT WORK when you are referring to an inexisting location. e.g. when you copied the code from somewhere else, or you haven’t created your menu or location yet in the dasboard. e.g. remove “, ‘theme_location’ => ‘primary’” from the following code: wp_nav_menu( array( ‘container’=> false, ‘menu_class’=> false, ‘menu_id’=> ‘ia_toplevel’, ‘theme_location’ => ‘primary’ … Read more
Using a custom Walker, the start_el() method has access to $depth param: when it is 0 the elemnt is a top one, and we can use this info to maintain an internal counter. When the counter reach a limit, we can use DOMDocument to get from full HTML output just the last element added, wrap … Read more
From class Walker_Nav_Menu: function start_lvl( &$output, $depth = 0, $args = array() ) Your child class must use the same signature: three arguments, the first one passed by reference. Every difference will raise the error you got. Note that $args defaults to an empty array, but you get an instance of stdClass, not an array. … Read more
You can achieve this using the wp_nav_menu_items hook. Let’s have a look at the following piece of code which shows the login/logout link on the primary menu location. add_filter( ‘wp_nav_menu_items’, ‘wti_loginout_menu_link’, 10, 2 ); function wti_loginout_menu_link( $items, $args ) { if ($args->theme_location == ‘primary’) { if (is_user_logged_in()) { $items .= ‘<li class=”right”><a href=”‘. wp_logout_url() .'”>’. … Read more
Method 1 You can add a constructor to your custom Walker to store some additional exclusion arguments, like: class custom_nav_walker extends Walker_Nav_Menu { function __construct( $exclude = null ) { $this->exclude = $exclude; } function skip( $item ) { return in_array($item->ID, (array)$this->exclude); // or return in_array($item->title, (array)$this->exclude); // etc. } // …inside start_el, end_el if … Read more
Hi @Tom, If I understand your question correctly you don’t so much need to know how to add a link to the menu (it seems you already know that) but instead need to learn how to get your link to redirect correctly, right? Redirecting to an External URL from an Admin Menu Item If so … Read more
Menu by itself is a taxonomy in WP. It means that you can find all menus in wp_terms table, by running following query: SELECT * FROM wp_terms AS t LEFT JOIN wp_term_taxonomy AS tt ON tt.term_id = t.term_id WHERE tt.taxonomy = ‘nav_menu’; Menu item is custom post type in WP. They are stored in wp_posts … Read more
wp_get_nav_menu_items would appear to be exactly what you require. It returns an array of menu objects.
The function wp_nav_menu takes an argument of fallback_cb which is the name of the function to run if the menu doesn’t exist. so change you code to something like this: function wp_nav_menu_no_ul() { $options = array( ‘echo’ => false, ‘container’ => false, ‘theme_location’ => ‘primary’, ‘fallback_cb’=> ‘fall_back_menu’ ); $menu = wp_nav_menu($options); echo preg_replace(array( ‘#^<ul[^>]*>#’, ‘#</ul>$#’ … Read more
I was also looking for a solution for this and I found simple one. This is what you need to place into the URL field: /index.php/internal-site-name It works just fine! Best Regards Chris
