Work around. if (is_page( ‘pagename’ ) || in_array(“5”, $post->ancestors)) { wp_nav_menu( array( ‘container_class’ => ‘subnav’, ‘menu’ => ‘visit’ )); } 5 being the ID of the page in question. So while this is a bit more work, needing and if / if:else statement for each page, it will scale to allow as many child / … Read more
You do not need a callback function at all. You could display (yet another) custom edit screen, but if the custom post type is set up correctly you should be able to reach it simply by pointing to http://yourdomain.com/wp-admin/post.php?post=9999&action=edit where 9999 is any post ID that corresponds to a post of said type. Hence you … Read more
In general it should not be a big problem. The built of the menu could be slow, so your best option here is to cache the menus with transient. if ( !get_transient( ‘first_menu_transient’ ) ) { ob_start(); // do not directly output the menu // build the menu $first_menu = ob_get_contents(); ob_end_clean(); echo $first_menu; set_transient( … Read more
Well you just need to run a foreach loop over your $children but WordPress has a build in function for this already called wp list pages. For example: $children = wp_list_pages(‘title_li=&child_of=”.$post->ID.”&echo=1’); if ($children) echo ‘<ul>’ . $children . ‘</ul>’; There is a full reference and examples here: http://codex.wordpress.org/Function_Reference/wp_list_pages
Use has_nav_menu to check if a location has been assigned a menu or not <?php if ( has_nav_menu( $location ) ) { echo “Also in this section”; } ?> http://codex.wordpress.org/Function_Reference/has_nav_menu For more advanced checks you’ll need to do a call to wp_get_nav_menu_items and process the items it returns to see if any of them are … Read more
The easiest and most clean way to solve that problem is using a specialised object. First create a class that can hold extra information: class Menu_Page { public $extra=””; public function render() { print $this->extra; } } Now create an object from that class … $page = new Menu_Page; $page->extra=”Hello World!”; … and register its … Read more
Creating a custom Walker is a valid way to solve this, and is the first thing that crossed my mind, but it is not strictly necessary. It is possible to pull this off with filters, albeit by mildly abusing one of them 🙂 Proof of concept: function insert_image_wpse_130477($item_output) { remove_filter(‘walker_nav_menu_start_el’,’insert_image_wpse_130477′); $prepend = apply_filters(‘my_item_prepend’,”); return $prepend.$item_output; … Read more
Insert the URL of the page as the $menu_slug argument. Also note that user levels are deprecated, you should pass a capability instead. function add_custom_link() { add_submenu_page( ‘edit.php?post_type=cpt_custom’, ”, ‘Pending Posts’, ‘edit_posts’, ‘edit.php?post_type=cpt_custom&post_status=pending’, ” ); } add_action(‘admin_menu’, ‘add_custom_link’);
Okays.. i’ve solved this in my own way. i have added the following function in functions.php file class ik_walker extends Walker_Nav_Menu{ //start of the sub menu wrap function start_lvl(&$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) { $output .= ‘ </ul> … Read more
I use this functions. First of all, you have to add some custom class to your menu item (allow class input in Screen options, it’s not visible by default). function mark_menu_item_as_active($classes, $item) { if( in_array(‘my-custom-class’,$classes) && ( is_category(‘my-category’) /* OR …*/ ) ) { $classes[] = ‘current-menu-item’; } return $classes; } add_filter(‘nav_menu_css_class’, ‘mark_menu_item_as_active’, 10, 2); … Read more
