Yii min 日期验证规则

问题描述

如何在模型中添加最短日期验证规则?

How can I add a minimum date validation rule in a Model?

示例:

我有一列 dt_ini 作为 DATE，我需要在创建时将输入限制为 D+7.

I have a column dt_ini as DATE, which I need to restrict the input as D+7, on create.

如果今天是:2012 年 10 月 1 日

If today is: october 1st, 2012

创建的最短有效日期为:2012 年 10 月 8 日.

the minimum valid date on create would be: october 8th, 2012.

否则，我会抛出一个验证错误:您的日期必须至少距现在 7 天.

Otherwise, I would throw a validation error as: Your date must be at least 7 days from now.

我期望的代码是这样的:(这没有经过测试，可能不会工作)

The code I would expect is something like this: (this is NOT tested, and probably won't work)

    public function rules(){
      return array('dt_ini', 'date', 'minDate' => '+7'),
    }

谢谢.

推荐答案

创建自定义有效规则如下:

Create custom valid rule as follows:

class YourModel extends CActiveModel
{
    // some....

    public function rules(){
      return array('dt_ini', 'dateValid', 'minDate' => '+7 day', 'on' => 'create');
    }

    public function dateValid($attribute, $params)
    {
        $valid=null;
        $today = date('Y-m-d', time());
        if(isset($params['minDate']))
            $valid = date('Y-m-d', strtotime($params['minDate'])); //+7 day

        if( !is_null($valid) )
        {  //for increamental date
            if($this->dt_ini >  $valid || $this->dt_ini < $today )
                $this->addError($attribute, 'enter error message');
        }
    }
}
