推荐答案

为什么要为要保存的值添加引号？教义会为你处理这个问题。尝试删除此部分：

Why do you add quotes to the values you are saving? Doctrine will handle this for you. Try removing this part:

$name="'".$this->form->getValue('username')."'";
$message="'".$this->form->getValue('message')."'";
$email="'".$this->form->getValue('email')."'";
$sub="'".$this->form->getValue('subject')."'";

您没有充分利用教义的功能，并充分体现。

You're not utilising the power of Doctrine and forms fully.

例如而不是这样：

$this->form = new ContactForm();

$this->rs = Doctrine::getTable('login')-> find($request->getParameter('id'));

$id=$request->getParameter('id');
$unm=$this->rs['username'];
$msg=$this->rs['message'];
$em=$this->rs['email'];
$sub=$this->rs['subject'];
$this->form->setDefault('id', $id);
$this->form->setDefault('username', $unm);
$this->form->setDefault('message', $msg);
$this->form->setDefault('email', $em);
$this->form->setDefault('subject', $sub);

您可以使用这个：

$this->rs =  Doctrine_Core::getTable('login')-> find($request->getParameter('id'));
$this->form = new ContactForm($this->rs);

您只需通过添加此功能将表单连接到适当的模型：

You only have to "connect" your form to a proper model by adding this function:

public function getModelName()
{
    return 'login';
}    

然后您可以使用 save 方法，以便它自动保存您的对象，而无需创建更新查询。

You could then use the save method on the form so it automatically saves your object without having to create the update query.

还可以看看 sfValidatorFile ，因为它会自动为您创建一个唯一的文件名。

Also have a look at the sfValidatorFile as it will automatically create a unique filename for you.
