我正在尝试根据场景添加验证码验证,我首先从数据库中检索失败尝试次数。我正在使用checkattempts()
函数。根据结果,我在视图中显示验证码,并在控制器中添加场景条件,如下所示。
在LoginForm模型中:
public function rules()
{
return [
[['username', 'password'], 'required', 'on'=>'loginpage'],
[['username', 'password'], 'required', 'on'=>'withCaptcha'],
[['reference_url'], 'safe'],
[['verifyCode'], 'captcha', 'skipOnEmpty' => true,'on'=>'withCaptcha'],
['username','email', 'on'=>'loginpage', 'message'=> 'Please enter a valid email address'],
['password', 'validatePassword', 'on'=>'loginpage'],
['password', 'validatePassword', 'on'=>'withCaptcha'],
];
}
public function checkattempts($uname)
{
$user = \frontend\models\User::findByEmail($uname);
$ip = $this->get_client_ip();
if($user){
$data = (new Query())->select('*')
->from('login_attempts')
->where(['ip' => $ip])->andWhere(['user_ref_id' => $user->id])
->one();
if($data["attempts"] >=3){
return true;
}else{
return false;
}
}
return false;
}
SiteController.php控制器中的
public function actionLogin() {
if (!\Yii::$app->user->isGuest) {
return $this->redirect(Yii::$app->getUrlManager()->getBaseUrl() . '/../../');
}
$model = new \common\models\LoginForm();
$model->scenario = 'loginpage';
$captcha = false;
if(Yii::$app->request->post()){
$post_variables =Yii::$app->request->post('LoginForm');
if ($model->checkattempts($post_variables['username'])) {
$model->scenario = 'withCaptcha';
$captcha = true;
}
}
if ($model->load(Yii::$app->request->post()) && $model->validate()) {
$model->login(); print_r($model->getErrors()); exit;
} else {
return $this->render('login', [
'model' => $model, 'captcha' => $captcha,
]);
}
在我的login.php视图中:
<?php if($captcha) { ?>
<?= $form->field($model, 'verifyCode')->widget(Captcha::className(),
['template' => '<div class="captcha_img">{image}</div>'
. '<a class="refreshcaptcha" href="#">'
. Html::img('/images/imageName.png',[]).'</a>'
. 'Verification Code{input}',
])->label(FALSE); ?>
<?php } ?>
在我的控制器中,当我在$ model-&gt; login()函数中打印模型错误时,即使验证码正确,它也会在每次都给出以下错误。
Array ( [verifycode] => Array ( [0] => The verification code is incorrect. ) )
为什么每次都失败了。代码中是否有任何错误?
