I have done a complete answer on this a while ago on SO. You can see the complete post here. For the sake of WPSE users, I have copied my answer from that post. I have not edited it, this post was originally about adding and displaying a nav menu to the footer, but the … Read more
As @toscho said, you can call the walker class with parameters as you did: new BEMwalker( ‘mobile’ ) The constructor of BEMwalker will take the arguments (like any other function or method in PHP) so you can access the parameter(s) via $this: class BEMwalker extends Walker_Nav_Menu { private $classes; public function __construct( $classes=”” ) { … Read more
Walker_Nav_Menu isn’t what you would use for this. Instead, use the wp_get_nav_menu_items filter. Before we start, you need some way of allowing the code to identify which is the menu item/page that you wish to be the parent of the list of posts. You can do this with a CSS class – give the parent … Read more
Apparently custom nav menu walkers are not supported though they were supposed to be. I’m surprised this only has been discovered now. However, there is an easy fix for you to get them to work. Just add this to your theme: add_filter( ‘wp_nav_menu_args’, function( $args ) { if ( isset( $args[‘walker’] ) && is_string( $args[‘walker’] … Read more
It’s pretty easy then… And it works exactly how it should… You register menu ‘footer ‘ – there’s a space at the end (so you have two locations defined ‘primary’ and ‘footer ‘). And then you use it as ‘footer’ – without that space. There is no such location defined anywhere 😉
Walker_Nav_Menu is the core class to handle navigation menus. You can use it to handle your navigation menu, or you can create your own children class that extends this class. If you decide to use your own class, then you must pass an instance as an argument when you use wp_nav_menu() class myWalkerClass Extends \Walker_Nav_Menu … Read more
Use the wp_nav_menu_objects filter to adjust the menu items using whatever conditions you like. The filter will receive and return an array of the menu items.
I had to do this too, but didn’t find a quick and easy way. Since jQuery is available in the wp admin, I used that to select all the delete links and trigger the click event on them: jQuery(‘#menu-to-edit’) .find(‘.submitdelete’) .trigger(‘click’);
The items are set up in wp_nav_menu(). There is a useful filter you can use: ‘wp_nav_menu_objects’. It offers the items as $sorted_menu_items and the arguments of the wp_nav_menu() call as $args. From wp-includes/nav-menu-template.php::wp_nav_menu(): $sorted_menu_items = apply_filters( ‘wp_nav_menu_objects’, $sorted_menu_items, $args ); So … hook into this filter, store the data somewhere, return the $sorted_menu_items unchanged and … Read more
On the wp_list_pages docs, it states that: If a given custom post type is hierarchical in nature, then wp_list_pages() can be used to list the member of that custom post type. Based on your code, the CPT that you are attempting to use with wp_list_pages() is not hierarchical. Therefore, two solutions: 1. Change the Custom … Read more
