You could create a very simple walker, like this one. To detect the current item, inspect $item->current. It is TRUE for the current item only. I wouldn’t add a class, but deactivate the useless link completely, because it doesn’t have to be clickable anyway. Example: class One_Line_Walker extends Walker { public function walk( $elements, $max_depth … Read more
Count the level 0 elements in a static variable in the method and add an extra class if you hit the third. Sample code: function start_lvl(&$output, $depth) { static $column = 1; $indent = str_repeat(“\t”, $depth); if ($depth > 0) { $output .= “\n$indent<ul class=”subsubmenu”>\n”; } else { $column += 1; $extra = 3 === … Read more
We could rewrite: wp_list_comments( array( ‘callback’ => ‘bootstrap_comment_callback’, )); with the null walker parameter: wp_list_comments( array( ‘walker’ => null, ‘callback’ => ‘bootstrap_comment_callback’, )); which means we are using the default Walker_Comment class: wp_list_comments( array( ‘walker’ => new Walker_Comment, ‘callback’ => ‘bootstrap_comment_callback’, )); The Walker_Comment::start_el() method is just a wrapper for one of these protected methods: … Read more
I do this using jQuery (since it doesn’t necessarily need to be in the TEXT (for screen readers, etc.) – just another option…: jQuery(document).ready(function() { jQuery(‘ul#nav li’).has(‘ul’).addClass(‘parentul’); }); Then for that “parentul” class I put in a background image of an arrow and position it to the right > …
Frankly, I’d just use a single menu and then apply a CSS class (in the backend) to the navigation element you want the to be. It’s simple enough to add a CSS class in the Menu editing pane, and that solves a lot of your difficulties since you can just check for the presence of … Read more
I stumbled across this article, I think it could be of tremendous use to you. It helped me understand it a lot better. I believe there was a question on here in which (I think) @Rarst answered that linked to it, but I can’t seem to find it. If someone can find it and edit … Read more
Your my_extended_walker class is OK, but when you call the wp_nav_menu function use the items_wrap parameter. wp_nav_menu( array( ‘items_wrap’ => ‘<p>%3$s</p>’, ‘walker’=>new my_extended_walker() ) ); The start_lvl is used for children elements.
I searched and read about the walker class. I ran tests, I played around with the code and I finally understood. I hope this can be helpful to others too. You’ll need to implement the walker class for this. Here is a simple example. $defaults = array( ‘theme_location’ => ‘primary’, ‘container’ => ‘ul’, ‘menu_class’ => … Read more
Call wp_get_nav_menu_object to get a menu object, which will give you the count of items for that menu. Example: // Get menu object $my_menu = wp_get_nav_menu_object( ‘your-menu-name-or-slug’ ); // Echo count of items in menu echo $my_menu->count; Hope that helps.
If I understand the problem setup correctly, you could try to do the break and widget class counting within the wp_nav_menu_objects filter. Here’s an updated example, it’s rather expanded because of the extra debug part: add_filter( ‘wp_nav_menu_objects’, function( $items, $args ) { // Only apply this for the ‘primary’ menu: if( ‘primary’ !== $args->theme_location ) … Read more
