Date validation in laravel 5
提问by Texas
I have a StartDate field and a EndDate field. Both may start today or in the future. It is possible to have them both start on the same day, including today. I have to make a validation for these. What I've done so far is this:
我有一个 StartDate 字段和一个 EndDate 字段。两者都可能在今天或将来开始。可以让它们都在同一天开始，包括今天。我必须对这些进行验证。到目前为止我所做的是：
'StartDate'=>'required|date_format:Y/m/d|after:yesterday',
'EndDate' => 'date_format:Y/m/d|after:yesterday',
What I don't know how to do is to validate true if both dates are equal as a second condition.
我不知道如何做的是验证两个日期是否相等作为第二个条件。
Anyone can help me, please ?
任何人都可以帮助我，好吗？

EDITThis was a solution up to Laravel 5.3. With Laravel 5.4, a rule after_or_equalwas introduced
编辑这是 Laravel 5.3 的解决方案。在 Laravel 5.4 中，after_or_equal引入了一条规则

I had the same need for my web app. I solved it by creating a custom Requestwith the following rulesmethod :
我对我的网络应用程序有同样的需求。我通过Request使用以下rules方法创建自定义来解决它：
public function rules()
{
$rules = [
'start_date' => 'date_format:Y-m-d|after:today'
];
if ($this->request->has('start_date') && $this->request->get('start_date') != $this->request->get('end_date')) {
$rules['end_date'] = 'date_format:Y-m-d|after:start_date';
} else {
$rules['end_date'] = 'date_format:Y-m-d|after:today';
}
return $rules;
}

This is how you can validate date:
这是您可以验证日期的方法：
'start_date' => 'required|date',
'end_date' => 'required|date|after_or_equal:start_date'

As per my understand I try to prepare custom validation rule which could help you to meet your requirement.
据我了解，我尝试准备自定义验证规则，这可以帮助您满足您的要求。
Current below mentioned rule only check if a start date is before end date.
当前下面提到的规则仅检查开始日期是否在结束日期之前。
<?php
namespace App\Providers;
use Validator;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider{
public function boot(){
Validator::extend('date_after', function($attribute, $value, $parameters) {
return strtotime( $value ) > strtotime( $this->attributes[ $parameters[0] ] );
});
Validator::extend('date_equal', function($attribute, $value, $parameters) {
return strtotime( $value ) == strtotime( $this->attributes[ $parameters[0] ] );
});
}
}
?>
Usage:
用法：
<?php
$inputs = array(
'start_date' => '2013-01-20',
'end_date' => '2013-01-15'
);
$rules = array(
'start_date' => 'required',
'end_date' => 'required|date_after:start_date'
);
$messages = array(
'date_after' => ":attribute must be date after Start Date."
);
$validation = Validator::make($inputs, $rules, $messages);
if( $validation->fails() )
{
echo '<pre>';
print_r($validation->errors);
echo '</pre>';
}
?>
However I did not test that code with my env... but I believe its help you much to meet requirement.
但是我没有用我的环境测试该代码......但我相信它对您满足要求有很大帮助。
Please let me know your further requirement so I can provide specifically solution to your requirement.
请让我知道您的进一步要求，以便我可以针对您的要求提供具体的解决方案。
