One of the darker corners of the code. 🙂 Here is my take: add_filter(‘nav_menu_css_class’, ‘discard_menu_classes’, 10, 2); function discard_menu_classes($classes, $item) { return (array)get_post_meta( $item->ID, ‘_menu_item_classes’, true ); }
add_menu_page(); as far as I can tell does not work with screen_icon or the default CSS parameters. The $icon paramater only takes 2 options, an url or div (well 3 if you leave it empty), so that leaves you with these options: Hard-code the link to the icons which are located in wp-includes/images/wpicons.png. This is … Read more
Think I worked it out!! I did a print_r on each $menu_item and saw there’s an array key called menu_item_parent in there. So I changed this: foreach ( (array) $menu_items as $key => $menu_item ) { $title = $menu_item->title; $url = $menu_item->url; $menu_output .= ‘<option value=”‘ . $url . ‘”>’ . $prefix . $title . … Read more

Yes, this is possible by adding a custom link to the menu assigning it any url (for this example I just added #) then click add to menu. Once it’s on the menu open it and remove the url you assigned and save. If you don’t put the url initially WordPress won’t let you add … Read more
Assuming that you have custom Nav Menus implemented properly: Registering nav menu Theme Locations: register_nav_menus( array( ‘parent_page’ => “Parent Page”, ‘page_a’ => “Page A”, ‘page_b’ => “Page B”, //etc ) ); Calling wp_nav_menu() correctly: wp_nav_menu( array( ‘theme_location’ => ‘page_a’ ); …then you can use the has_nav_menu() conditional to determine if a Theme Location has a … Read more
wp_nav_menu() indeed tries a lot to provide you with a menu, and fallback_cb is only executed when nothing else works. From the code: If menu is provided and refers to an existing menu (looked up via wp_get_nav_menu_object(), which accepts an id, slug or name), this will be the menu Otherwise, if theme_location is set to … Read more
Put the following in your functions.php class SH_Last_Walker extends Walker_Nav_Menu{ function display_element( $element, &$children_elements, $max_depth, $depth=0, $args, &$output ) { $id_field = $this->db_fields[‘id’]; //If the current element has children, add class ‘sub-menu’ if( isset($children_elements[$element->$id_field]) ) { $classes = empty( $element->classes ) ? array() : (array) $element->classes; $classes[] = ‘has-sub-menu’; $element->classes =$classes; } // We don’t … Read more
Have you tried using the before or link_before parameters in your array arguments when declaring your wp_nav_menu function? Note: use after or link_after for the opposite effect. Example, wp_nav_menu( //normal arguments here….etc ‘before’ => ‘<span class=”arrow”></span>’, //or ‘link_before’ => ‘<span class=”arrow”></span>’, ); From the Codex: $before (string) (optional) Output text before the of the link … Read more
