yii prompts an error when entering the correct verification code

When making a request, I found that the correct verification code was entered, but the verification code error was prompted.

Finally, following the code, we found that if the Model is validated separately before saving, the verification code will be regenerated after the verification is completed. Then when we Model save, we will also perform validate verification. During verification, the verification code has been regenerated, so it will not match.

Problem discovery:

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;
        }        
        // 這里會重新生成
        if ($session[$name] > $this->testLimit && $this->testLimit > 0) {
                    $this->getVerifyCode(true);
        }
                return $valid;
    }
}
// 如果這里用到了驗證碼,就會出問題$model = new Test();

$model->validate();

$model->save();
// 這樣是正確的$model = new  Test();
// 把需要驗證的 attribute 放進去,排除驗證碼字段
$model->validate(array(&#39;test1&#39;,&#39;test2&#39;));
$model->save()
