    验证规则

    1、内置验证规则

       [['sex', 'partner_id'], 'integer'],
       [['partner_id', 'camp_id',], 'required'],
       [['created_at', 'pics'], 'safe'],
       [['name'], 'string', 'max' => 16],
      [['interest', 'quota'], 'number'],
       [['path'], 'unique'],
      ['email', 'email'],
      ['website', 'url', 'defaultScheme' => 'http']; #说明:CUrlValidator 的别名, 确保了特性是一个有效的路径.
      ['username', 'unique', 'targetClass' => 'ackendmodelsUser', 'message' => '用户名已存在.'],
      [['file'], 'file', 'skipOnEmpty' => true, 'extensions' => 'png, jpg'],
     

    2、正则验证规则

    //默认值
    ['status', 'default', 'value' => self::STATUS_ACTIVE],
    //区间
    ['status', 'in', 'range' => [self::STATUS_ACTIVE, self::STATUS_DELETED]],
    //正则
    ['mobile','match','pattern' => '/^1[3456789]{1}d{9}$/','message'=>'请输入正确的手机号'],
    ['name', 'match','not'=>true, 'pattern' => '/^[0-9]+/','message'=>'不能全为数字或以数字开头'],

    3、过滤

        ['desc', 'filter', 'filter' => function ($value) {
                    if (empty($value)){
                        return null;
                    }
                    //过滤特殊字符
                    return Str::purify($value);
                }],

    filter(CFilterValidator )-----过滤验证方法:
    实例:

    ['name', 'test', 'message'=> '请填写姓名']
    public function test($object, $attributes) {
    if($this->name != '张先森') {
    $this->addError($object, $attributes['message']);
    }
    }

    //去空格

    ['username', 'password', 'repassword', 'captcha', 'age', 'sex', 'phone','email'], 'filter', 'filter'=>'trim', 'on'=>'register'],

    4、验证码

      ['yzm', 'captcha'],

    5、适用场景(自定义场景、或方法)

     ['shop_id', 'required','on'=>self::SCENARIO_ADMIN_CREATE],

    6、比较

      ['quota', 'compare', 'compareValue' => 9999.99,'type'=>'number', 'operator' => '<='],//
    [['discount','payment','pay_method'],'default','value'=>0],
     
    ['status', 'compare', 'compareValue' =>$this->oldAttributes['status'],'type'=>'number', 'operator' => '>=','message'=>'状态不能回撤'],//新修改的状态必须大于原有的状态
    数值大小
    ['age', 'compare', 'compareValue' => 30, 'operator' => '>=']; #说明:compareValue(比较常量值) - operator(比较操作符) #说明:CCompareValidator 的别名,确保了特性的值等于另一个特性或常量.
    
    

    7、时间

      ['uptime', 'date','format'=>'yyyy-MM-dd', 'timestampAttribute'=>'uptime'],

    8,条件唯一(比如同一个班级身份证必须唯一)

     ['name', 'required', 'message' => '请选择门店!'],
            ['shop_id', 'required', 'message' => '请输入菜品名称!'],
            ['name', //只有 name 能接收错误提示,数组['name','shop_id']的场合,都接收错误提示
             'unique', 'targetAttribute'=>['name','shop_id'] ,
             'targetClass' => 'modelsDishes', // 模型,缺省时默认当前模型。
             'comboNotUnique' => '选择的门店内,该菜品名称已经存在!' //错误信息
            ],
    
    //自定义函数
       ['name', 'check','on'=>['create']],//定义规则,在create场景中对name进行check方法验证,下面是方法的定义函数
    public function check($attribute,$params){
        if (empty($this->shop_id)) {
            return $this->addError($attribute,'请选择门店!');
        }
        $dish=Dishes::findOne(['name'=>$this->name,'shop_id'=>$this->shop_id]);
        if($dish){
            $this->addError($attribute, '该菜品名称已存在!');
        }else{
            $this->clearErrors($attribute);
        }
    }

     默认值

    ['updated_at','default','value'=>time(),'on'=>[self::SCENARIO_ADD],'skipOnEmpty'=>false],
                ['updated_at','editUpdatedAt',on'=>[self::SCENARIO_ADD],'skipOnEmpty'=>false],
