Try the code....... 

<?php 

class UsersController extends AppController { 

    public function update($id = null) { 
     if ($id) { 
      if ($this->request->is('post')) { 
       $this->User->id = $id; 
       $this->User->save($this->request->data); 
      } else { 
       $this->set('user', $this->User->find('first', array('conditions' => array('id' => $id)))); 
      } 
     } 
    } 

}

@burzum我找到了解決我的問題，在模型updateAll（）在模型中可用的方法使用這個我有更新表的行。

public function update($id) 
    { 
     if(isset($_REQUEST['update'])) 
     { 
      $this->User->id=$id; 
      if($this->User->updateAll(array('User.fname'=>"'".$_REQUEST['fname']."'",'User.lname'=>"'".$_REQUEST['lname']."'",'User.email'=>"'".$_REQUEST['email']."'"),array('id'=>$id))) 
       echo '<script>alert("update successfully")</script>'; 
      else 
       echo '<script>alert("failes to update ")</script>'; 
     } 
     else 
     $this->set('user',$this->User->find('first',array('conditions'=>array('id'=>$id)))); 
    }
