First off, you should not register functions loose in functions.php because you cannot remove them (using remove_action). It can also cause debug errors since WP may not yet be stable. By using a hook you are making sure WP is stable enough to run your code, and what you need to use has been loaded. … Read more
The parameter fallback_cb will be used when the user has no menu assigned to your theme_location. It should be a function that returns a string, but you can use __return_false() to suppress any output: wp_nav_menu( array( ‘theme_location’ => ‘primary’, // No menu available: no output. ‘fallback_cb’ => ‘__return_false’ ) ); You should always declare the … Read more
Admin menu & submenu separators After going over it and extending the core API to allow main menu separators in custom positions, I did a quick run through core menu files, dumped the hell out of everything’s that in there and found a solution that allows to use the core API also for custom submenu … 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
The Starkers theme setup is hooked to after_setup_theme, at a priority of 10. So you basically have to wrap the unregister function inside another function (child themes functions.php file) and add it later than the parent themes setup function, so it gets first added by the parent and later on removed by the child. function … Read more
Use is_main_query() to modify only the main query so menu will stay not affected. Try This: add_action( ‘pre_get_posts’, ‘fteh_pre_get_posts’ ); function fteh_pre_get_posts( $query ){ if( !is_admin() && $query->is_main_query() && isset( $query->query_vars[‘type’] ) ) $types = explode( ‘,’, $query->query_vars[‘type’] ); $query->set( ‘post_type’, $types ); return $query; }
If you look in the wp_nav_menu() function, you see the items are written by walk_nav_menu_tree(), which calls Walker_Nav_Menu to do the work (unless you specified your own walker class). This class contains a method start_el() that is called for each menu item. In this function, you see that the classes are filtered through nav_menu_css_class and … Read more
I’m going against the majority on this one 🙂 Yes, it can be a good idea to strip it down. Personally I’m keeping only the current-xxx type classes and replacing them with active, and active-parent (for active parent or ancestor items). Why? around the web, active has became the standard class for active menu items … Read more
That function just registers new menus. If you want to create a custom type of menu, you need to create your own extended menu walker that would do something custom or activate any other functionality. If you would like to have the top pages listed (in a menu or other situation), you can use wp_list_pages … Read more
Another option is to toggle the CSS Classes checkbox under screen option, WP Admin > Appearance > Menus, and attach the icon to a CSS class. And add your icons using psuedo selectors to the CSS class.
