php中header跳转使用include包含解决参数丢失问题
在一个项目中遇到的问题,当用户登录成功时,用header跳转到首页,一直都是错,无法跳到你要的页面。最终度娘了许久才找到解决方法,这里分享给大家。
有同事反映,最近上线的几款游戏海外注册载入不了样式文件,需要紧急修复。
注册程序统一走单一入口,,核心判断是checkip处,只需要在未实名认证的模板程序处做一个game_id的判断即可。因为太过肯定、急于下班的心理,再加上大家催促的紧张,一下子就蒙了,犯了两个错误:一是game_id的判断位置提前了,导致后面的很多变量没有传到目的页面;二是没有理解header跳转和include包含的涵义,直接用了header做跳转。
header跳转后的页面,不能继承上一页的变量等元素,举例说明:
a.php文件
$userEname = "crystal"; $userCname = "程程"; //your code ................................ header("location:b.php"); //your code ..................
如果在b.php文件里引用$userEname,你猜结果是什么?此时的$userEname = null。如果用include包含b.php的话,就能避免$userEname为空的问题了。
以上所述就是本文的全部内容了,希望大家能够喜欢。
