Validating a custom date format in with laravel validator
提问by jacobdo
In my app, the user selects date from a datepicker and the date is then displayed in the input in a format that corresponds user's locale.
在我的应用程序中，用户从日期选择器中选择日期，然后该日期以对应于用户语言环境的格式显示在输入中。
When the form is submitted, I would like to validate the respective date, however, the validator does not know the date format that the date was submitted in.
提交表单时，我想验证相应的日期，但是，验证器不知道提交日期的日期格式。
My question is whether I should mutate the date into Y-m-d before it is passed to validator or is there a way I can tell the Validator the right format to validate in?
我的问题是我是否应该在将日期传递给验证器之前将日期更改为 Ymd，或者有没有办法告诉验证器要验证的正确格式？

The easier option is to use the Laravel date_format:formatrule (https://laravel.com/docs/5.5/validation#rule-date-format). It's a built-in function in Laravel without the need for a custom rule (available in Laravel 5.0+).
更简单的选择是使用 Laraveldate_format:format规则（https://laravel.com/docs/5.5/validation#rule-date-format）。它是 Laravel 中的内置函数，无需自定义规则（在 Laravel 5.0+ 中可用）。
You can do:
你可以做：
$rule['date'] = 'required|date_format:d/m/Y';
or
或者
$rule['date'] = 'required|date_format:Y-m-d';

Laravel Custom Validation Rules
You can define the multi-format date validation in your AppServiceProvider
您可以在您的 AppServiceProvider
class AppServiceProvider extends ServiceProvider
{
public function boot()
{
Validator::extend('new-format', function($attribute, $value, $formats) {
foreach($formats as $format) {
$parsed = date_parse_from_format($format, $value);
// validation success
if ($parsed['error_count'] === 0 && $parsed['warning_count'] === 0) {
return true;
}
}
// validation failed
return false;
});
}
}
Now you can use custom validation rule:
现在您可以使用自定义验证规则：
'your-date' => 'new-format:"Y-m-d H:i:s.u","Y-m-d"'
'your-date' => 'new-format:"Y-m-d H:i:s.u","Y-m-d"'
