请在函数中添加此代码。php删除；“类别”；permalink中的文本。

function remove_category( $string, $type ) {
    if ( $type != \'single\' && $type == \'category\' && ( strpos( $string, \'category\' ) !== false ) ){
        $url_without_category = str_replace( "/category/", "/", $string );
        return trailingslashit( $url_without_category );
    }
    return $string;
}
add_filter( \'user_trailingslashit\', \'remove_category\', 100, 2);
