Here is the answer I ended up with: $select_cats = wp_dropdown_categories( array( ‘echo’ => 0 ) ); $select_cats = str_replace( “name=”cat” id=”, “name=”cat[]” multiple=”multiple” id=”, $select_cats ); echo $select_cats; It displays a list of my categories that can be multi-selected as per my question. It’s a hack of wp_dropdown_categories, but it works.
You could use get_categories(). Returns an array of category objects matching the query parameters. Arguments are pretty much the same as wp_list_categories and can be passed as either array or in query syntax. // Fetch parent categories $parent_categories = get_categories( ‘parent=0’ ); foreach ( $parent_categories as $parent_category ) { // Fetch child categories $args = … Read more
Try to do all theme modifications in functions.php whenever possible. It keeps the theme files clean and uncluttered. Here’s an example using the pre_get_posts action: function order_category_archives( $query ) { if ( is_category() && $query->is_main_query() ){ // is_category() can specify a category, if necessary $query->set( ‘orderby’, ‘title’ ); $query->set( ‘order’, ‘ASC’ ); } } add_action( … Read more
very similar approach to the answer by @AndrettiMilas: add_filter(‘wp_list_categories’,’style_current_cat_single_post’); // filter to add the .current-cat class to categories list in single post function style_current_cat_single_post($output) { if( is_single() ) : global $post; foreach ( get_the_category($post->ID) as $cat ) { $cats[] = $cat->term_id; } foreach($cats as $value) { if(preg_match(‘#item-‘ . $value . ‘”>#’, $output)) { $output = … Read more
There is a function called get_category_link() which might be helpful for you. This will be able to generate an appropriate link without having to hard-code it, except for the category name or ID.

As I mentioned in my comment, you can use add_rewrite_endpoint to accomplish this. First, add the endpoint: function wpa_author_endpoints(){ add_rewrite_endpoint( ‘liked-posts’, EP_AUTHORS ); } add_action( ‘init’, ‘wpa_author_endpoints’ ); After flushing rewrite rules (visit your Settings > Permalinks page in admin), author URLs can now be appended with /liked-posts/. Next, add a filter to author_template to … Read more
There are several built-in CSS classes that come with the wp_nav_menu. In your case, you are looking for something like a current category class, which is not included. But we can easily add that to the CSS classes: function wpse_134409_current_category_class($classes, $item) { if ( is_single() && ‘category’ === $item->object && in_array($item->object_id, wp_get_post_categories($GLOBALS[‘post’]->ID)) ) $classes[] = … Read more
Take a look at the source of wp_dropdown_categories(). It uses walk_category_dropdown_tree() to render the output.
