yii自定义验证

• 自定义验证类

  class BaseModel extends Model {
    public function rules() {
          return [
              ['obj', ContentSecurityValidator::class],
          ];
      }
    public function exec() {
          if (!$this->validate()) {
              return [
                  'errors' => $this->errors
              ];
          }
     }
    public function attributeLabels() {
          return [
              'obj' => '标签',
          ];
      }
  }
  
  /**
  * 自定义验证类
  */
  class BaseValidator extends Validator {
  
       /**
       * 必须要实现该方法
       * @param \yii\base\Model $model
       * @param string $attribute 参数名
       * @return bool
       */
      public function validateAttribute($model, $attribute) {
          $attributeValue = $model->$attribute;//获取$model里面的参数的值
          $attributes = $model->attributes;//获取model里面的参数数组
          $attributeLabels = $model->attributeLabels();//获取model里面的已经设置好参数对应标签
  
      }
  }

• 自定义验证方法

  class BaseModel extends Model {
    public function rules() {
          return [
              ['obj', 'validate'],
          ];
      }
    public function exec() {
          if (!$this->validate()) {
              return [
                  'errors' => $this->errors
              ];
          }
     }
    public function attributeLabels() {
          return [
              'obj' => '标签',
          ];
      }
    /**
     * 自定义方法
     */
    public function validate($attribute) {
          $attributeValue = $this->$attribute;//获取$model里面的参数的值
          $attributes = $this->attributes;//获取model里面的参数数组
          $attributeLabels = $this->attributeLabels();//获取model里面的已经设置好参数对应标签
  
      }
  }
  

• 不刷新，通过切换select的按钮，面对不同场景时，设置某些必填项

  public function rules() {
          return [
              [['email', 'phone'], "requiredValidators", 'skipOnEmpty' => false, 'skipOnError' => false],
          ];
      }
  
      public function requiredValidators($attribute) {
          if ($this->typeId == 'register') {
              $isAttrEmpty = !$this->$attribute || empty($this->$attribute) || $this->$attribute === '' || $this->$attribute == null;
              if ($isAttrEmpty)
                  $this->addError($attribute, $this->attributeLabels()[$attribute] . '不能为空');
          }
      }
  
      public function attributeLabels() {
          return [
              'email'=>'邮箱',
              'phone'=>'手机'
          ]
      }
