Preface

When I was making a request recently, I found that I entered the correct verification code, but it was prompted that the verification code was wrong

Finally, following the code, we found that if the Model was separately verified before saving, then after the verification is completed, the verification code

will be regenerated and then when we Model save , it will also be performed validate. During verification, the verification code has been regenerated, so it will not match

// 如果这里用到了验证码，就会出问题

$model = new Test();

$model->validate();

$model->save();

// 这样是正确的

$model = new Test();
// 把需要验证的 attribute 放进去，排除验证码字段
$model->validate(array('test1','test2'));

$model->save()

We can look at framework/web/widgets/captcha/CCaptchaAction.php and we can easily find the problem

<?php

class CaptchaAction extends CCaptchaAction 
{
 public function validate($input, $caseSensitive)
 {
 $code = $this->getVerifyCode();
 $valid = $caseSensitive ? ($input === $code) : !strcasecmp($input, $code);
 $session = Yii::app()->session;
 $session->open();
 $name = $this->getSessionKey() . &#39;count&#39;;
 if (!Yii::app()->request->isAjaxRequest) {
  $session[$name] = $session[$name] + 1;
 }

 // 这里会重新生成
 if ($session[$name] > $this->testLimit && $this->testLimit > 0) {
  $this->getVerifyCode(true);
 }
 return $valid;
 }
}
