The easiest way is to extend the Walker_Nav_Menu class rather than the Walker_Class, (as the parent / ID fields are set and often you want to maintain some of the mark-up etc). The main methods are: start_el / end_el – responsible for displaying an element in a list start_lvl / end_lvl – responsible for displaying … Read more
It means that the declaration of the start_lvl method in wp_bootstrap_navwalker should match the declaration of the method in Walker_Nav_Menu. It doesn’t. function start_lvl( &$output, $depth ) { VS. function start_lvl( &$output, $depth = 0, $args = array() ) { Make the arguments match exactly and you should be fine. And you should probably not … Read more
I think the “Featured Post Manager” plugin will be closer to what you’re looking for: http://wordpress.org/extend/plugins/featured-post-manager/screenshots/ The language used is somewhat confusing, and it may not work for custom taxonomies (directories) or custom types (people), BUT you can probably take the code and customize it to work for those classes of things instead, as well … Read more
I would go for custom nav menu walker… //define the custom post type and custom taxonomy define(“MENU_CPT”, “people”); define(“MENU_CT”, “club”); //custom function for selecting posts based on a term function get_posts_by_term($term_id, $post_type=MENU_CPT, $taxonomy=MENU_CT) { $args = array( ‘posts_per_page’ => -1, ‘post_type’ => $post_type, ‘tax_query’ => array( array( ‘taxonomy’ => $taxonomy, ‘field’ => ‘id’, ‘terms’ => … Read more
Here is a much simpler implementation: class UL_Submenu_Walker extends Walker_Nav_Menu { private $hidden = false; function start_lvl(&$output, $depth) { if($depth == 0) { $style = $this->hidden ? “” : “display:none;”; } $output .= “<ul class=\”submenu-“.$depth.”\” style=””.$style.””>”; } function start_el(&$output, $item, $depth, $args) { $class_names = $value=””; $classes = empty( $item->classes ) ? array() : (array) … Read more
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
