The base paradigm in WordPress is The Callback Handler. Actions, filters, widgets, metaboxes and so on … everything runs by registering specific callback handlers for some triggers. This is not always the most elegant way, but the one every beginner must learn, so stick to that paradigm, whenever you’re not sure what to do. So … Read more
Assuming that you have custom Nav Menus implemented properly: Registering nav menu Theme Locations: register_nav_menus( array( ‘parent_page’ => “Parent Page”, ‘page_a’ => “Page A”, ‘page_b’ => “Page B”, //etc ) ); Calling wp_nav_menu() correctly: wp_nav_menu( array( ‘theme_location’ => ‘page_a’ ); …then you can use the has_nav_menu() conditional to determine if a Theme Location has a … Read more
Okay, the problem was in my interpretation of the filter. I was under the impression that this filter could be used for all images in a post, as they’re all considered attachments in the db (post type – attachment), but it’s actually reserved for the Featured Image/Post Thumbnail. Nowhere in the examples I looked through … Read more
wp_enqueue_script is not going to work in a shortcode, this is because of the loading order. You could use wp_register_script and then you could wp_enqueue_script in you shortcode function like this example: // Front-end function front_end_scripts() { wp_register_script( ‘example-js’, ‘//example.com/shared-web/js/example.js’, array(), null, true ); } add_action( ‘wp_enqueue_scripts’, ‘front_end_scripts’ ); Then you use this in your … Read more
I had the same problem, but with a newer version of WordPress (3.7.1). On pages with custom taxonomies of custom posts, the wp_nav_menu was not shown. The solution below worked for me. in functions.php of the theme: add_action( ‘pre_get_posts’, ‘my_pre_get_posts’ ); function my_pre_get_posts($query) { if ($query->get(‘post_type’) === ‘nav_menu_item’) { $query->set(‘tax_query’,”); } }
There is a workaround to hide this automatically created submenu. In the past I’ve used it quite often, but lately I have returned to leaving it as is (or renaming it, as m0r7if3r suggested). Also note, that aside your main question, you have switched the positions of the menu_slug and function arguments in add_menu_page, see … Read more
If you create an admin theme plugin from the Codex steps, you will notice it says not to insert stylesheets as per above – although the above will work. If you place the following inside your admin theme file, it will serve the same purpose, but uses the wp_enqueue_styles approach: function add_admin_theme_styles() { wp_register_style($handle=”mytheme-theme-admin-styles”, $src … Read more
I can’t come up with good quote, but as far as I understand from chatter – pointers are not considered public (available for use outside core) for version 3.3 So essentially there is no API to use yet.
<?php $args = array( ‘taxonomy’ => ‘product-type’, ‘hierarchical’ => true, ‘title_li’ => ”, ‘hide_empty’ => false ); ?> <ul> <?php wp_list_categories( $args ); ?> </ul> You can use the wp_list_categories function also for taxonomies. http://codex.wordpress.org/Template_Tags/wp_list_categories
You could use this simple function call which returns either TRUE or FALSE depending on if $children is an empty array or not. /** * Check if given term has child terms * * @param Integer $term_id * @param String $taxonomy * * @return Boolean */ function category_has_children( $term_id = 0, $taxonomy = ‘category’ ) … Read more
