yii的rules验证规则

• 图片验证

  public function rules() {
          return [
              [['id'], 'integer'],
              [['id'], 'required'],
              [['files'], 'file', 'maxSize' => 50 * 1024 * 1024, 'maxFiles' => 10, 'mimeTypes' => ['image/*', 'audio/*', 'video/*']],
          ];
      }

• 场景验证

    public function rules() {
          return [
              [['username','password'],'required','on'=>'login']
          ]
   }
  
    public function exec(){
  
      $this->scenario = "login";
       if (!$this->validate()) {
              return [
                  'errors' => $this->errors,
              ];
          }
   }    

• 对指定字段规定范围验证

  public function rules() {
          return [
             ['week', 'in', 'range' => [1,2,3,4,5,6,7]]
  ];
