WordPress 技巧：获取 Term 的分类模式

WordPress 竟然没有一个根据 $term_id 获取分类模式 taxonomy 的函数，那就自己写一个：

function get_term_taxonomy($id){
	$term	= get_term($id);

	return ($term && !is_wp_error($term)) ? $term->taxonomy : null;
}

这样在其他代码中就方便调用了，并且还处理了返回是 WP_Error 的情况。 😁

哪一天如果 WordPress 自己也支持了？那就加上 function_exists 的判断：

if(!function_exists('get_term_taxonomy')){
	function get_term_taxonomy($id){
		$term	= get_term($id);

		return ($term && !is_wp_error($term)) ? $term->taxonomy : null;
	}
}

好，非常完美，加入 WPJAM Basic，下一版本上线的时候，就有该函数了。
