I believe you want get_queried_object. If you have set your static front page and blog page from wp-admin->Settings->Reading then get_queried_object will give you information about the page you chose rather than about the posts in the Loop. Be aware that get_queried_object will return very different types of information depending on the kind of page you … Read more
Nav menus are also generated by a WP_Query, so in your pre_get_posts callback function you need to check if the $query you’re altering is the main query. The easiest way to do this would probably be to do this right at the beginning of the function: if ( ! $query->is_main_query() ) return $query; Also note … Read more
To get the current role of the user $current_user = wp_get_current_user(); if ( !($current_user instanceof WP_User) ) return; $roles = $current_user->roles; //$roles is an array After getting role set page ids which you want to show according to roles (for example) if($roles==’administrator’){ $args=array(’21’,’22’,’23’); } or if($roles==’subscriber’){ $args=array(’24’,’25’,’26’); } you can use parse_query filter hook to … Read more
You could use a custom walker or just filter the menu title. It depends on the position you need for your extra content: Should it appear before or inside the link? Example with a walker Update: Actually, this cannot work: the parent function creates the <li, so you have to copy and adjust the whole … Read more
This is what I went with in the end. Although it only will work correctly if you are using a depth of one: class Bar_List_Walker_Page extends Walker_Page { public $count; public $running_count; function __construct() { $this->count = 0; $this->running_count = 0; } function start_el(&$output, $page, $depth, $args, $current_page) { global $post; extract($args, EXTR_SKIP); $css_class = … Read more
add_filter( ‘wp_get_nav_menu_items’, ‘nav_remove_empty_category_menu_item’, 10, 3 ); function nav_remove_empty_category_menu_item ( $items, $menu, $args ) { global $wpdb; $nopost = $wpdb->get_col( “SELECT term_taxonomy_id FROM $wpdb->term_taxonomy WHERE count = 0” ); foreach ( $items as $key => $item ) { if ( ( ‘taxonomy’ == $item->type ) && ( in_array( $item->object_id, $nopost ) ) ) { unset( $items[$key] … Read more
Log queries As the question says “it doesn’t happen always”, it’s hard to tell what’s really going on. When you can’t see what happens (query in background) and don’t know when it happens, then it’s best to log it. The logger On activation, the plugin will try to create a log directory named ‘nav_log’ in … Read more
This is the slimmed down version of a plugin settings page that I’m working on. Put it in a file and include it in your plugin. Searching on Google for add_options_page, register_setting, add_settings_field etc. will lead you to the codex entries of WordPress with further descriptions. The code of the options page below will render … Read more
add_filter( ‘wp_page_menu’, ‘your_custom_menu_item’, 10, 2 );
It is not intuitive but get_terms will do it, if I understand what you need. var_dump(get_terms( ‘nav_menu’)); If you look in the *_term_taxonomy table you can see why. The menus are stored as a taxonomy named nav_menu. This won’t get you things like page menus, only the intentionally created menus.
