Create Custom Taxonomies In WordPress

Taxonomies groups your content into specific categories. For example, you have tutorials on WordPress, WooCommerce and Drupal on your website. You can group them into topics like:

WordPress Tutorials
WooCommerce Tutorials
Drupal Tutorials

Creating a taxonomy on a WordPress website is easy. Just use the code below in your functions.php file and you are good to go:

addaction( 'init', 'createcwhierarchicaltaxonomy', 0 );
//create a custom taxonomy name
function createcwhierarchicaltaxonomy() {
$labels = array(
'name' => _x( 'Topics', 'taxonomy general name' ),
'singularname' => x( 'Topic', 'taxonomy singular name' ),
'searchitems' => _( 'Search Topics' ),
'allitems' => _( 'All Topics' ),
'parentitem' => _( 'Parent Topic' ),
'parentitemcolon' => _( 'Parent Topic:' ),
'edititem' => _( 'Edit Topic' ),
'updateitem' => _( 'Update Topic' ),
'addnewitem' => _( 'Add New Topic' ),
'newitemname' => _( 'New Topic Name' ),
'menuname' => _( 'Topics' ),
);
// taxonomy register
registertaxonomy('topics',array('post'), array(
'hierarchical' => true,
'labels' => $labels,
'showui' => true,
'showadmincolumn' => true,
'query_var' => true,
'rewrite' => array( 'slug' => 'topic' ),
));
}
