Yii2框架自定义验证规则操作示例

class AbcModel extends Model
{
  public $aaa;
  public $bbb;
  public $bbb;
  /**
   * 验证提交的form表单
   *
   * @return array
   */
  public function rules()
  {
    return [
      // 自定义验证
      [['aaa', 'bbb', 'ccc'], 'customValidationCityCode'],
    ];
  }
  public function customValidationCityCode($attribute, $params)
  {
    if (!isset($this- $attribute)
      || empty($this- $attribute)
      || !is_array($this- $attribute)
    ) {
      $this- addError($attribute, "值为空或不存在或类型不符合.");
      return;
    }
  }
}
