You can extend it, but the class definition and any code that uses it, can’t run outside of the admin area. Wrap your class in this conditional: if ( is_admin() ) { … } If you are trying to use this on the frontend or other non-Admin areas, do not do that. Generally, classes WordPress … Read more
After some testing I found the best way is to use a walker. For this example lets say that this is the code that calls our menu wp_nav_menu([ ‘container’ => false, ‘theme_location’ => ‘right-side-top-menu’, ‘walker’ => new Menu_Middle_Logo() ]); Now for our walker, there isn’t an easy way to determine which of the parent menu … Read more
I would recommend using get_pages() rather than wp_list_pages() for this purpose. The get_pages() function will return an array of objects of Pages, and you can use the array data to build your own HTML list. e.g.: <?php // Wrap in a function, for later output; function wpse47989_list_pages() { // Get an array of pages using … Read more
Your code doesn’t because the global $post refers to the post/page being viewed (if there is one…). What is passed with nav_menu_css_class is a menu item – this is a particular post type. Among its properties are: object which stores: the post type if the link refers to a post the taxonomy if the link … Read more
You can try the !is_admin() so your code would be: function wpse31748_exclude_menu_items( $items, $menu, $args ) { // Iterate over the items to search and destroy if ( !is_admin() && is_user_logged_in() ) { $registerpage = get_page_by_title( ‘Register’ ); $loginpage = get_page_by_title( ‘Login’ ); foreach ( $items as $key => $item ) { if ( $item->object_id … Read more
You can use the wp_get_nav_menu_object to retrieve the menu as an object, which you can subsequently establish the length of. Like this: $wpse140949_menu = wp_get_nav_menu_object( ‘your-menu-name-or-slug’ ); $tabcount = $wpse140949_menu->count; You can the use this on your call to wp_nav_menu: wp_nav_menu ( array ( ‘menu_class’ => ‘item-‘ . $tabcount, …. ));
You can try to skip the CategoryThumbnailWalker and use instead the list_cats filter. Here’s an untested example: add_filter( ‘list_cats’, ‘wpse_149898_list_cats’, 99, 2 ); wp_list_categories(array( “child_of” => get_queried_object_id(), “depth” => 1, “hide_empty” => false, “hierarchical” => 1, “orderby” => “name”, “pad_counts” => 0, “post_type” => “projects”, “show_count” => 0, “show_option_none” => “”, “taxonomy” => “project-category”, “title_li” … Read more
If all of it is your own code then it would be reasonable to just implement that as part of walker. If you need to add a filter while third party walker runs you could probably: Add it at wp_nav_menu_args hook, checking if walker is set to that: add_filter( ‘wp_nav_menu_args’, function( $args ) { if … Read more
Okays.. i’ve solved this in my own way. i have added the following function in functions.php file class ik_walker extends Walker_Nav_Menu{ //start of the sub menu wrap function start_lvl(&$output, $depth) { $output .= ‘<div class=”dropdownContain”> <div class=”dropOut”> <div class=”triangle”></div> <ul>’; } //end of the sub menu wrap function end_lvl(&$output, $depth) { $output .= ‘ </ul> … Read more
I’m not sure if this is what you’re after. You can use $this to reference the current walker instance. class YPE_custom_navwalker extends Walker_Nav_Menu { public function start_lvl(&$output, $depth=0, $args=array()) { $items = wp_get_nav_menu_items( $args->menu->term_id ); echo $this->get_number_of_root_elements( $items ); parent::start_lvl(&$output, $depth,$args); } }
