让用户在登录后回到上一页？ [英] Take user back to previous page after logging in?

问题描述

相应的功能如下所示：

  function signin（）
 {
 if（！empty（$ this-> data））
 {
 //句柄登录
 ... 
 //保存登录到会话
 $ this-> Session-> write（'Account'，$ data [Account]）; 
 //重定向到上一页
 ??? 
} 
} 
 
 function signout（）
 {
 //删除登录
 $ this-> Session-> delete '帐户'）; 
 //重定向到上一页
 ??? 
} 
  

如果用户转到 accounts / signin 它首先检查表单是否提交 if（！empty（$ this-> data））如果是，它会记录它们，if不是它呈现登录形式。如果他们成功登录，我想将他们重定向到他们在登录页面之前的页面。

最好的方法是什么？

编辑：

我认为我无法使用常规http引荐来源网址，因为将始终是登录页面，因为他们去 / signin ，然后提交登录表单。因此，在提交表单的地方，引荐来源始终为 / signin 。我想重定向到他们之前的地方。这是否有意义？

使用隐藏的 < input> 字段，用于保存初始引荐来源网址，并与登录数据一起提交。

I have a controller called Accounts, with the views signin and signout.

The corresponding functions look like this:

function signin()
{
    if (!empty($this->data)) 
    {
        //handle login
        ...
        //save login to session
        $this->Session->write('Account',  $data["Account"]);
        //redirect to previous page
        ???
    }
}

function signout()
{
    //delete login
    $this->Session->delete('Account');
    //redirect to previous page
    ??? 
}

If the user goes to accounts/signin it first checks to see if the form is submited if(!empty($this->data)) if yes, it logs them in, if not it renders the signin form. If they do succesfully log in, I want to redirect them to the page they were at before the signin page.

Whats the best way to do that?

Edit:

I do not think I can user a regular http referrer because technically the referrer will always be the signin in page because they go to /signin, then submit the sign in form. So at the point where the form is submited the referrer is always /signin. I want to redirect to where they were before that. Does that make sense?

Use a hidden <input> field that holds the initial referrer and gets submitted with the login data.
