您可以这样注册自定义分类法：

<?php
// Register custom taxonomy for locations
function mamaduka_register_taxonomy_location() {
    register_taxonomy( \'location\', array( \'post\' ), array(
        \'hierarchical\' => true,
        \'label\' => \'Locations\',
        \'public\' => true,
    ));
}
add_action( \'init\', \'mamaduka_register_taxonomy_location\' );
?>
