Php 模型场景yii上的验证规则冲突

我有如下模型的验证规则

public function rules()
{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    //post of step 1
    if (isset($_POST['yt0']))
    {
        return array(
                array('EmailAddress,', 'required','message' =>  Yii::t('message', 'USERNAME_REQUIRED')),
                array('Password,', 'required','message' =>  Yii::t('message', 'PASSWORD_REQUIRED')),
                array('confirmPassword,', 'required','message' => Yii::t('message', 'CONFIRM_PASSWORD_REQUIRED')),
                array('Password','length', 'max' => 100, 'min' => 6, 'tooShort' => Yii::t('message', 'PASSWORD_LENGTH')),
                array('confirmPassword', 'compare', 'compareAttribute'=>'Password','message' => Yii::t('message', 'PASSWORD_COMPARE')),
                array('EmailId,', 'required','message' => Yii::t('message', 'EMAILID_REQUIRED')),
                array('EmailId','email','message'=>Yii::t('message', 'EMAILID_VALID')),
                array('chapterCode,', 'required','message' => Yii::t('message', 'CHAPTERCODE_REQUIRED')),
                array('verifyCode,', 'required','message' =>Yii::t('message', 'VERIFYCODE_REQUIRED')),
                array('verifyCode', 'captcha', 'allowEmpty'=>!CCaptcha::checkRequirements(),'caseSensitive'=>true,'message' =>Yii::t('message', 'VERIFYCODE_INCORRECT') ),
                array('EmailAddress', 'unique','className'=>'User','attributeName'=>'EmailAddress','message'=>Yii::t('message', 'EMAILID_UNIQUE')),
                array('PersonId', 'unique','className'=>'User','attributeName'=>'PersonId','message'=>"Person already exists."),

这里的

yt0

是注册页面上提交按钮的名称，因此对于注册，将应用

yt0

的规则，并且我有另一个更改密码的表单，因此在该页面上，我只需要三个字段，更改密码的提交按钮是

savecontact

，但是会应用savecontact规则，但是注册按钮规则冲突，因此注册时的验证无效。这是正确的方法来纠正上述规则吗？请提供任何建议。…

虽然这可能有效，但您的做法是错误的。 您应该使用

场景

来执行此类任务

首先，您可以为不同的表单声明场景：

class User extends ActiveRecord
{
    const SCENARIO_LOGIN = 'login';
    const SCENARIO_SIGNUP = 'signup';
    const SCENARIO_UPDATE = 'update';
}

定义场景后，您可以告诉您的模型使用哪些属性进行大规模分配，并对特定场景应用验证

class User extends ActiveRecord
{
    const SCENARIO_LOGIN = 'login';
    const SCENARIO_REGISTER = 'register';
    const SCENARIO_UPDATE = 'update';

    public function scenarios()
    {
        return [
            self::SCENARIO_LOGIN => ['username', 'password'],
            self::SCENARIO_REGISTER => ['email', 'username', 'password'],
            self::SCENARIO_UPDATE => ['email', 'username', 'password'],
        ];
    }
}

完成后，您可以选择添加验证规则或使用gii生成的默认规则

class User extends ActiveRecord
{
    const SCENARIO_LOGIN = 'login';
    const SCENARIO_REGISTER = 'register';
    const SCENARIO_UPDATE = 'update';

    public function scenarios()
    {
        return [
            self::SCENARIO_LOGIN => ['username', 'password'],
            self::SCENARIO_REGISTER => ['email', 'username', 'password'],
            self::SCENARIO_UPDATE => ['email', 'username', 'password'],
        ];
    }

    public function rules()
    {
        return ArrayHelper::merge([
            ['email' => 'email', 'message' => Yii::t('message', 'wrong email format')],
            [['email', 'password', 'username'] => 'email'],
            ['username', 'exist', 'on' => self::SCENARIO_LOGIN], // this will apply only on login
            // other rules
        ], parent::rules());
    }
}

现在您已经完成了模型场景和规则，是时候正确使用它们了

前往控制器并使用以下场景实例化模型：

public function actionLogin()
{
    $model = new User(['scenario' => User::SCENARIO_LOGIN]);

    if($model->load(Yii::$app->request->post())) {
        // $model will have username and password even if email is in the form since it is using
        // User::SCENARIO_LOGIN
        $model->validate(); 
        // will validate only username and password even if email is in the form
        // will also use the username exist validator
        // do your stuff
    }
}

public function actionRegister()
{
    $model = new User(['scenario' => User::SCENARIO_REGISTER]);

    if($model->load(Yii::$app->request->post())) {
        // $model will have username, password and email
        $model->validate(); 
        // will validate email, username and password but will not use the
        // username exist validation rule since it has the `'on' => self::SCENARIO_LOGIN`
        // do your stuff
    }
}
