通过头文件传递php变量 [英] passing php variables through header

问题描述

我想通过标头传递一个变量。在我的系统中，用户停留在个人资料页面上并点击链接填写并提交表格。提交表单时，页面将重定向到配置文件页面。当我的个人资料页面显示时，会员ID已经丢失，所以它不显示会员详细信息。我想要做的是在重定向发生时传递成员ID。
$ b $ pre $ 函数redirect_to（$ location = NULL）{
if（$ location！= NULL）{
标题（ 位置：{$位置}）;
出口;
}
}


redirect_to（'member_profile.php'）;


我想要做的是这个

  redirect_to的（ 'member_profile.php ID = $ mselcted_memberI？'）; 
  

解决方案

您正在使用单引号 '这将使它成为一个字符串，而是使用。来连接，而不是

  redirect_to的（ 'member_profile.php ID =？' $ mselcted_memberI。）; 
  

另外，您不需要大括号 {} here

  header（Location：$ location）; 
  

I want to pass a variable through header. In my system the user stays on the profile page and click on a link to fill and submit a form. When the form is submitted the page redirect to the profile page. When I the profile page displayed the member id has lost, so it don't display the member details. What I want to do is pass the member id when redirecting happens.

function redirect_to($location = NULL){
    if($location != NULL){
        header("Location:{$location}");
        exit;
    }
}


redirect_to('member_profile.php');

what I am trying to do is this

redirect_to('member_profile.php?id=$mselcted_memberI');

解决方案

You are using single quotes ' which will make it a literal string, instead, concatenate that using a . instead

redirect_to('member_profile.php?id='.$mselcted_memberI);

Also, you don't require braces {} here

header("Location:$location");
