指向 你的models 在rules添加上验证规则

 public function rules()
 {
  return [
   [['t_leave_date', 't_days', 't_reason', 't_nickname','t_leave_enddate'], 'required'],
   [['t_leave_date', 't_leave_enddate'], 'safe'],
   [['t_days'], 'number'],
   [['t_reason'], 'string'],
   [['type', 'add_time', 'uid', 'update_time', 'status', 'is_shen'], 'integer'],
   [['t_pickup', 't_nickname', 't_pass'], 'string', 'max' => 20],
   [['t_img', 'reviewer_user', 'audit_user'], 'string', 'max' => 255]
  ];
 }
