我在 YII 中制定了以下验证规则，不知何故正则表达式似乎不起作用：
Yii 模态中的规则：
public function rules()
{
return array(
array('password, email, username, password_confirmation', 'required'),
array('password','match', 'pattern'=> '/^[a-zA-Z]'w{5,20}$/','message'=>"{attribute} should contain only alphanumeric and underscore."),
array('email_conf', 'numerical', 'integerOnly'=>true),
array('username, email, login_source', 'length', 'max'=>150),
array('email','email'),
array('password, password_confirmation', 'length', 'min'=>6, 'max'=>200),
array("password", "compare", "compareAttribute" => "password_confirmation"),
array('fb_id', 'length', 'max'=>100),
// The following rule is used by search().
// @todo Please remove those attributes that should not be searched.
array('id, username, email, password, login_source, fb_id, email_conf', 'safe', 'on'=>'search'),
array("password_confirmation, email_conf", "safe")
);
}
在上面的代码中，我关心的行如下：
array('password','match', 'pattern'=> '/^[a-zA-Z]'w{5,20}$/','message'=>"{attribute} should contain only alphanumeric and underscore."),
正则表达式是这样的，它将只接受字母作为第一个字符和特殊字符
不会被接受，空格也不会被接受。
现在不知何故，即使我使用了正确的 YII 语法(检查一下如何在 YII 中使用正则表达式(
正则表达式似乎不起作用.
我为这种模式创建了一个简单的PHP文本案例：
<?php
if (isset($_POST['submit'])) {
$holder = $_POST['regex'];
$regrex = preg_match('/^[a-zA-Z]'w{5,20}$/', $holder);
if ($regrex) {
echo "Match";
}
else {
echo "Not match";
}
}
?>
<form action="" method="post" >
<input type="text" name="regex"><br><br>
<button type="submit" value="submit" name="submit">Submit</button>
</form>
正则表达式工作得很好！，那么即使我正确遵循 YII 语法，YII 中有什么问题？
编辑：
视图文件中的相应标签如下所示：
<div class="">
<?php echo $form->labelEx($model,'password'); ?>
<?php echo $form->passwordField($model,'password',array('size'=>50,'maxlength'=>50)); ?>
<?php echo $form->error($model,'password'); ?>
</div>
特纳利。
编辑：控制器代码 ：
public function actionCreate()
{
$model=new User;
// Uncomment the following line if AJAX validation is needed
// $this->performAjaxValidation($model);
if(isset($_POST['User']))
{
$username = $_POST['User'];
if(isset($username['email'])) {
$record=User::model()->find(array(
'select'=>'*',
'condition'=>'email=:email',
'params'=>array(':email'=>$username['email']))
);
}
if($record===null){
$model->attributes=$_POST['User'];
$model->password = crypt($model->password,'salt');
$model->password_confirmation = crypt($model->password_confirmation,'salt');
//$model->password = $model->password;
if($model->save()){
// confirm mail send
$confirm_record=User::model()->find(array(
'select'=>'*',
'condition'=>'email=:email',
'params'=>array(':email'=>$username['email']))
);
$to = $username['email'];
$subject = 'Confirm your Account';
$htmlBody = "Welcome and thank you for registering at Aaskar Pet Resort!<br>";
$htmlBody .= "Your account has now been created and you can log in by using your email address and password by visiting our website.<br>";
$htmlBody .= "<p><a style='text-decoration:none;' href ='".Yii::app()->request->hostInfo.''.$this->createUrl('site/confirmed',array('id'=> base64_encode($confirm_record['id'])))."'>Confirm your account</a></p>";
$htmlBody .= "<p>Upon logging in, you will be able to access other services including reservation for your pets, booking services and editing your account information.</p>";
$htmlBody .= "<p>Thanks,<br>Aaskar Pet Resort</p>";
$headers = "MIME-Version: 1.0" . "'r'n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "'r'n";
$headers .= 'From: <donotreply@purplefront.net>' . "'r'n";
$sent = mail($to, $subject, $htmlBody, $headers);
if($sent){
$message = $this->dynamicStatus('create_success');
Yii::app()->user->setFlash('success', $message);
$this->redirect(array('site/index'));
}
//Yii::app()->user->setFlash('success', 'Account has been created');
//$this->redirect(array('site/index'));
}
}else{
$message = $this->dynamicStatus('email_exist');
Yii::app()->user->setFlash('error', $message);
}
}
$this->render('create',array(
'model'=>$model,
));
}
这也是上面关于 pastebin 的代码链接，以防万一它有帮助：

为什么password参数 safe(( 仅用于search场景？
array('id, username, email, password, login_source, fb_id, email_conf', 'safe', 'on'=>'search'),
您可能需要检查 from 使用的模型方案。为什么不尝试使这些对所有方案都是安全的：
array('id, username, email, password, login_source, fb_id, email_conf', 'safe'),

从您的控制器/操作代码中，我看到在您获取密码字段后立即执行密码加密。但是您错过了针对上述模型规则的验证。因此，如果您想进行验证，请在加密之前进行：
$model->attributes=$_POST['User'];
$model->validate(); // validation is performed
$model->password = crypt($model->password,'salt');
$model->password_confirmation = crypt($model->password_confirmation,'salt');
...
// comment one or another of the following lines:
$model->save(); // again validation is performed
$model->save(false); // no validation is performed when saving AR
如果要使用已加密的密码在save()中转义验证，请执行以下操作：$model->save(false); 。
