Question

我想为新记录预填充一些字段值。我可以在下面看到硬代码，但我不能从$ lesson数组中提取它们，当我在视图中设置变量时，我无法从隐藏字段中获取它们。在find中我得到了我需要的值，那么我用什么方法从find中提取变量？

      $lesson=$this->set( 'lesson',$this->Lesson->find('first',$options));

       if ($this->request->is('post')) {

         $this->TrequestAmend->create();
   $this->request->data['TrequestAmend']['lesson_id']=6; //I want o set this value to lesson_id found in find first above but how???
               $this->request->data['TrequestAmend']['tutor_id']=2;
                $this->request->data['TrequestAmend']['student_id']=2;



            if ($this->TrequestAmend->save($this->request->data)) {
                $this->Session->setFlash(__('Your Tutor Requested Amended data has been saved.'));
               // return $this->redirect(array('action' => 'displayall'));
            }
            else
            $this->Session->setFlash(__('Unable to add your post.'));
       }

//     view 
echo $this->Form->input($lessonId, array('type' => 'hidden'));
    echo $this->Form->input($tutorId, array('type' => 'hidden'));
   echo $this->Form->input($stId, array('type' => 'hidden'));

Answer 1

$lesson = $this->Lesson->find('first', $options);
$this->request->data['TrequestAmend']['lesson_id'] = $lesson['Lesson']['id'];

$this->set(compact('lesson'));

Answer 2

如果将值设置为模型$this->request->data的{{1}}，则必须确保为此模型创建了表单（我写这个是因为您没有在此处发布此行）。

TrequestAmend

然后，在为其名称创建表单输入时，必须在视图中更改变量。所以这样做：

echo $this->Form->create('TrequestAmend');

就是这样，现在你应该能够预先填写表格了。

首先从find中提取变量
