验证规则冲突的警予模型场景

Question

我有一个模型，具体如下

public function rules() 
{ 
    // NOTE: you should only define rules for those attributes that 
    // will receive user inputs. 
    //post of step 1 
    if (isset($_POST['yt0'])) 
    { 
     return array(
       array('EmailAddress,', 'required','message' => Yii::t('message', 'USERNAME_REQUIRED')), 
       array('Password,', 'required','message' => Yii::t('message', 'PASSWORD_REQUIRED')), 
       array('confirmPassword,', 'required','message' => Yii::t('message', 'CONFIRM_PASSWORD_REQUIRED')), 
       array('Password','length', 'max' => 100, 'min' => 6, 'tooShort' => Yii::t('message', 'PASSWORD_LENGTH')), 
       array('confirmPassword', 'compare', 'compareAttribute'=>'Password','message' => Yii::t('message', 'PASSWORD_COMPARE')), 
       array('EmailId,', 'required','message' => Yii::t('message', 'EMAILID_REQUIRED')), 
       array('EmailId','email','message'=>Yii::t('message', 'EMAILID_VALID')), 
       array('chapterCode,', 'required','message' => Yii::t('message', 'CHAPTERCODE_REQUIRED')), 
       array('verifyCode,', 'required','message' =>Yii::t('message', 'VERIFYCODE_REQUIRED')), 
       array('verifyCode', 'captcha', 'allowEmpty'=>!CCaptcha::checkRequirements(),'caseSensitive'=>true,'message' =>Yii::t('message', 'VERIFYCODE_INCORRECT')), 
       array('EmailAddress', 'unique','className'=>'User','attributeName'=>'EmailAddress','message'=>Yii::t('message', 'EMAILID_UNIQUE')), 
       array('PersonId', 'unique','className'=>'User','attributeName'=>'PersonId','message'=>"Person already exists."), 
       array('FailedLoginCount', 'safe'), 
     ); 
    } elseif (isset($_POST['yt1'])) 
    { 
     return array(
       array('EmailAddress,', 'required','message' => Yii::t('message', 'USERNAME_REQUIRED')), 
       array('Password,', 'required','message' => Yii::t('message', 'PASSWORD_REQUIRED')), 
       array('FailedLoginCount', 'safe'), 

     ); 
    }elseif (isset($_POST['savecontact'])||$this->memBelongsto==0) 
    { 
     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'),'except'=>'datavalid'), 
       array('EmailId','email','message'=>Yii::t('message', 'EMAILID_VALID'),'except'=>'datavalid'), 
       array('FailedLoginCount', 'safe'), 

     ); 
    }else{ 
     return array(
       array('EmailAddress,EmailId, Password', 'required'), 
       array('PersonId, ActiveFlag, FailedLoginCount', 'numerical', 'integerOnly'=>true), 
       array('EmailAddress, Password', 'length', 'max'=>100), 
       array('confirmPassword,', 'required','message' => Yii::t('message', '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('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('FailedLoginCount', 'safe'), 
     ); 
    } 
} 

验证规则和这里yt0是yt0规则将被应用提交注册页面上，因此对注册按钮的名字，我有另一种在该页面上更改密码的表单我只需要三个字段，更改密码的提交按钮是savecontact，但会应用savecontact规则，但注册按钮规则冲突，因此注册验证无效。是否正确的方式正确的规则如上任何建议请......

虽然这可能工作，你是在做错误的方法。 您应该使用scenario来执行这些类型的任务。

首先，您可以为不同的形式申报的情况：

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

当你与定义的场景进行，你可以告诉你的模型是什么属性，使用大量的任务和特定的应用验证场景。

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'], 
     ]; 
    } 
} 

现在你已经完成了，你可以选择添加验证规则或使用由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，你与你的模型场景和规则进行，时间要正确地使用它们。

头到控制器，并使用情景实例化你的模型：

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 
    } 
}
