get_term_children returns an array or an object (WP_Error) and you are treating it like a string when you try to feed it to substr. I am not sure what you are trying to do with that line of code but in general you need to check that you are dealing with an array and not … Read more
WordPress add “current-menu-item” class for the active menu item, you could check if this class is set and the set the option for that item be selected. class Walker_Nav_Menu_Dropdown extends Walker_Nav_Menu { function start_lvl($output, $depth) { } function end_lvl($output, $depth) { } function start_el($output, $item, $depth, $args) { // Here is where we create each … Read more
Found that I was including the Bootstrap.min.js from the footer.php and this caused the issues. When the URL was wrong in functions.php then the js called from Footer made the menu show correct but then gave a console error for the incorrect URL called in functions.php, while when both were called correctly they clashed.

I use this navwalker <?php class wp_bootstrap_navwalker extends Walker_Nav_Menu { public function start_lvl( &$output, $depth = 0, $args = array() ) { $indent = str_repeat( “\t”, $depth ); $output .= “\n$indent<ul role=\”menu\” class=\” dropdown-menu\”>\n”; } public function start_el( &$output, $item, $depth = 0, $args = array(), $id = 0 ) { $indent = ( $depth … Read more

Test for … $item->object=”custom” This is used for custom links only. $item->object is always the post type or the item type (category for example). Not sure what happens when someone registers a custom post type named custom 🙂
I have found a working solution. It’s a plugin called Advanced Menu Widget. I had to add a widget area into my theme but I can live with that, for now. It works!
My solution uses the Walker_Nav_Menu and a custom class and is mostly hacked together from this post: How do I dynamically populate wp_nav_menu from a custom taxonomy? Solution: //define the custom post type //could use “page” or “post” as well. define(“MENU_CPT”, “action”); //custom function for selecting posts based on a page parent (ne’ term_id) function … Read more
All of the methods are being overridden when you load your own walker, but typically you would extend another Walker which works a bit like “filtering” or “pluggable functions”. Take a look at this very simple walker from another question: class my_extended_walker extends Walker_Nav_Menu { function start_lvl(&$output, $depth = 0, $args = array()) { $output … Read more
