从 cakePHP 中的 auth 获取引荐来源网址

我的主页上有一个链接，只有登录后才能访问。但是，如果单击此链接，我想在登录页面上显示自定义错误消息（自定义“Message.auth”）。

即我想要（伪代码）

if (referer == '/users/reserve'){
    Message.auth = 'Please log in to reserve tickets';
}
else {
    Message.auth = 'Please log in to access that page';
}

我应该把这段代码放在哪里？

原文

I have a link on the main page that is only accessible if they are logged in. However, if this link is clicked, I want to show a custom error message on the login page (a custom 'Message.auth').

i.e. I want (pseudo code)

if (referer == '/users/reserve'){
    Message.auth = 'Please log in to reserve tickets';
}
else {
    Message.auth = 'Please log in to access that page';
}

Where would I put this bit of code?

如果您在登录视图中输出了身份验证闪存消息，那么这应该可以工作：

// login action of users_controller.ctp
if ($this->Session->check('Auth.redirect')
 && $this->Session->read('Auth.redirect') == '/users/reserve') {
  $this->Session->write('Message.auth', 'Please log in to reserve tickets');
}

Provided you have auth flash messages being output in the login view, this should work:

// login action of users_controller.ctp
if ($this->Session->check('Auth.redirect')
 && $this->Session->read('Auth.redirect') == '/users/reserve') {
  $this->Session->write('Message.auth', 'Please log in to reserve tickets');
}
