如何在场景中设置安全或允许空的验证码？

Question

我想在类似下面的代码的场景中设置安全或允许空验证码。

var date  = new Date();
var month = new Array();

month[0] = "January";
month[1] = "February";
month[2] = "March";
month[3] = "April";
month[4] = "May";
month[5] = "June";
month[6] = "July";
month[7] = "August";
month[8] = "September";
month[9] = "October";
month[10] = "November";
month[11] = "December";

[month[n-3],month[n-2], month[n-1], month[n]]

但它不起作用，我收到了这个错误。

 public function rules() {
        return [
            [['verifyCode'], 'safe', 'on'=>'admin'],
        ];
    }

并且this page也没有帮助我。

试试这个。添加规则：

[['verifyCode'], 'captcha', 'skipOnEmpty' => true, 'on'=>'admin']

在控制器中，当创建实例时：

$model->scenario = 'admin';
