查看無法正確顯示

Question

我現在正在學習Cake並且正在關注IBM's tutorial。我已經從蛋糕網站成功完成了博客教程。
我的問題是，Register視圖不顯示。不是顯示錶單，而是立即執行register()操作，檢查表單參數是否爲空的條件總是失敗，所以我總是無法註冊用戶消息。

CTP的文件看起來像這樣（它不使用傭工）：

<form action="https://stackoverflow.com/users/register" method="post"> 
<p>Please fill out the form below to register an account.</p> 
<label>Username:</label><input name="username" size="40" /> 
<label>Password:</label><input type="password" name="password" size="40" /> 
<label>Email Address:</label><input name="email" size="40" maxlength="255" /> 
<label>First Name:</label><input name="first_name" size="40" /> 
<label>Last Name:</label><input name="last_name" size="40" /> 
<input type="submit" value="register" /> 
</form> 

而且register()動作是：

function register() { 
    if (!empty($this->params['form'])) 
    { 
     if ($this->User->save($this->params['form'])) 
     { 
      $this->flash('Your registration infomration was accepted.', '/users/register'); 
     } 
    } 
    else 
    { 
     $this->flash('There was a problem with your registration', '/users/register'); 
    } 
} 

Answer 1

嘗試：

function register() { 
    if (!empty($this->data)) { 
     $this->User->create(); 
     if ($this->User->save($this->data)) { 
      $this->flash('Your registration infomration was accepted.', '/users/register'); 
     } else { 
      $this->flash('There was a problem with your registration', '/users/register'); 
     } 
    } 

} 

最大的區別是使用$this->data而不是$this->params[form]，並加入$this->User->create();。另外else語句應該與if（用戶保存）閃存保存，否則閃存不保存。
