As the Codex says, this is the code block to query for only the Top Label categories — the parents. With this, I used the PHP function count(). <?php $args = array( ‘parent’ => 0, ‘hide_empty’ => 0 ); $categories = get_categories( $args ); echo count( $categories ); ?>
Yes, and you’re quite close to it. Just use the $postarr parameter of this filter: add_filter( ‘wp_insert_post_data’ , ‘wpse128138_wp_insert_post_data’, 99, 2 ); function wpse128138_wp_insert_post_data( $data, $postarr ) { // run this only for posts if ( ‘post’ != $postarr[‘post_type’] ) return $data; foreach( $postarr[‘post_category’] as $category_id ) { if ( is_wp_error( $category = get_category( $category_id … Read more
Probably your hosting server has a different and older version of php so this syntax is not supported. The above syntax is implemented in PHP 5.4. You have to do it like this: $category = get_the_category($id); echo $category[0]->slug; Source: https://bugs.php.net/bug.php?id=45906
Notice that you don’t need echo to display the result, since echo=1 is the default settings of wp_get_archives(). As @PieterGoosen explained, the wp_get_archives() function doesn’t support the exclude parameter. But we can use _exclude_terms, the custom parameter of the wp_get_archives() function, to exclude posts with some given terms. Here’s an example: /** * Exclude terms … Read more
The following code will do it. Please change the ‘filter’ text in the below code to whatever filters taxonomy name you have set. if(is_category() ){ $thiscat = get_queried_object_id(); $filter_tax = array(); $args = array( ‘category’ => $thiscat ); $lastposts = get_posts( $args ); foreach ( $lastposts as $post ){ setup_postdata( $post ); $terms = get_the_terms( … Read more
If by “main” category you mean the category that is used to create the permalink, the default is to use the category with the lowest ID. You can access the post also with an URL that contains another category, but the rewrite_canonical() function will kick in and redirect you to the “canonical” URL with the … Read more
You can do something like this: function category_has_parent($catid){ $category = get_category($catid); if ($category->category_parent > 0){ return true; } return false; } and use it like this: if (category_has_parent(’22’)){ //true there is a parent category }else{ //false this category has no parent } Update: to check the other way around (if a category has children) you … Read more
Why hack apart what’s already there? If you remove the built in taxonomies, you’ll end up creating hiccups in core code that expect them to be there! You’re much better off just editing your theme file(s), or filtering out categories on the front-end (ask if you need help on that). For example, in your theme’s … Read more
Sounds like you are looking for the functionality of WordPress 3.0 Menus Subpanel. In Dashboard go to ‘Appearance’ then ‘Menus’ and you can create a page that will show the posts from a specified category.
The way i’d do it: First – create a page in the wp admin. Then create a file like mypage.php. Save it in your theme and a the top of it, add this to tell wordpress that this is a custom page template: <?php /* Template Name: Custompage */ get_header(); ?> Note: it’ll also already … Read more
