推荐答案
对您发布的早期问题的答案将正确设置car_id。所有你现在需要做的是将它添加到您的表单中add.ctp正确。
Assuming you used the answer to the earlier question you posted you will have the car_id set correctly. All you now need to do is add it to your form in add.ctp correctly.
替换：
echo $this->Form->input('car_id');
使用
echo $this->Form->input('car_id', array('type'=>'hidden', 'value'=>$car_id));
然后，您的表单将正确保存car_id。
Your form will then save the car_id correctly.
