从a.php向b.php传递参数的控制有关问题

从a.php向b.php传递参数的控制问题~
a.php里面有一个form表单,表单指向action="b.php",然后是通过post提交的。b.php里是接收这些表单里的数据(只有两个数据,都是字符串类型),然后向数据库里执行INSERT操作,然后通过header("Location:a.php")返回a.php页面。
问题就是:
我如何确保b.php只能通过a.php的表单提交来访问,而禁止其它一切访问方式?
比如检测表单的变量是否存在?

------解决方案--------------------
判断 $_SERVER['HTTP_REFERER'] 即可
