You are using the wrong function. Try: $thiscat = $wp_query->get_queried_object(); var_dump($thiscat); I don’t know exactly what you want to do with this information but you will get an object (stdClass) with ~15 items in it. You should be able to find what you need.
You can use pre_get_posts action to exclude categories from search query. function wcs_exclude_category_search( $query ) { if ( is_admin() || ! $query->is_main_query() ) return; if ( $query->is_search ) { $query->set( ‘cat’, ‘-22, -21’ ); } } add_action( ‘pre_get_posts’, ‘wcs_exclude_category_search’, 1 ); You should paste this code in your theme’s functions.php file.
Try adding this code to functions.php file: add_action(‘pre_get_posts’, ‘ad_filter_categories’); function ad_filter_categories($query) { if ($query->is_main_query() && is_home()) { $query->set(‘category_name’,’news, uncategorized’); } } category_name is the slug or the nicename of the category. Add a comma separated list of the categories you wish to include.
In addition to the answer by Tim, one can always use a proper tax_query. All the build in tag and category parameters gets converted to a proper tax_query before being passed to the WP_Tax_Query class to build the JOIN clause for the SQL query. I use a tax_query in almost all applications as it gives … Read more
You can get ID from slug quite easily: $category = get_category_by_slug( ‘clients’ ); wp_list_categories(‘child_of=”.$category->term_id);
Add this code to your functions.php file and it will remove the parentheses and surround the post count with a span with a class to easily style it. function categories_postcount_filter ($variable) { $variable = str_replace(‘(‘, ‘<span class=”post_count”> ‘, $variable); $variable = str_replace(‘)’, ‘ </span>’, $variable); return $variable; } add_filter(‘wp_list_categories’,’categories_postcount_filter’); ++Bonus In the archive widget, if … Read more
Here is a code I used to do it: // make category use parent category template function load_cat_parent_template($template) { $cat_ID = absint( get_query_var(‘cat’) ); $category = get_category( $cat_ID ); $templates = array(); if ( !is_wp_error($category) ) $templates[] = “category-{$category->slug}.php”; $templates[] = “category-$cat_ID.php”; // trace back the parent hierarchy and locate a template if ( !is_wp_error($category) … Read more
This should work: add_action( ‘init’, ‘wpa12742_init’ ); function wpa12742_init(){ add_rewrite_rule( ‘category/(.+?)/(\d{4})/?$’, ‘index.php?category_name=$matches[1]&year=$matches[2]’, ‘top’ ); add_rewrite_rule( ‘category/(.+?)/(\d{4})/page/(\d+)/?$’, ‘index.php?category_name=$matches[1]&year=$matches[2]&paged=$matches[3]’, ‘top’ ); } EDIT On second thought, that’s not enough, since you’ll get caught by redirect_canonical(). Add this too: add_filter( ‘term_link’, ‘wpa12743_term_link’, 10, 3 ); function wpa12743_term_link( $link, $term, $taxonomy ){ if(‘category’ != $taxonomy && !preg_match( ‘@^\d{4}$@’, get_query_var(‘year’) … Read more
This “feature” has been in WP for quite a while. You can disable it by installing this small plugin: http://wordpress.org/extend/plugins/category-checklist-tree/
I know this question is quite old but since there is no answer yet an there are many similar questions on the WordPress support forums, I’ll better share my findings and maybe help someone. The issue of disappearing menu may be caused by code in plugin or theme incorrectly modifying global $wp_query object using pre_get_posts … Read more
