将此代码添加到函数中。php，

add_action( \'init\', \'build_taxonomies\', 0 );  

function build_taxonomies() {

  register_taxonomy( \'category\', \'post\', array(
        \'hierarchical\' => true,
        \'update_count_callback\' => \'_update_post_term_count\',
        \'query_var\' => \'category_name\',
        \'rewrite\' => did_action( \'init\' ) ? array(
                    \'hierarchical\' => false,
                    \'slug\' => get_option(\'category_base\') ? get_option(\'category_base\') : \'category\',
                    \'with_front\' => false) : false,
        \'public\' => true,
        \'show_ui\' => true,
        \'_builtin\' => true,
