Laravel 5.3 date validator: equal to or after start_date
提问by Paul Z.
I'm using Laravel 5.3 to validate start_date and end_date for an event.
end_date should be equal to start_date or the after date. end_date >= start_date
我正在使用 Laravel 5.3 来验证事件的 start_date 和 end_date。end_date 应等于 start_date 或之后的日期。end_date >= start_date
$validator = Validator::make($data, [
'start_date' => 'required|date',
'end_date' => 'required|date|after:start_date',
]);
I tried to use after, but it only works for end_date > start_date.
Of course, I can add custom rule using Validator::extend, but I'd like to know if we can do without adding custom rule.
我尝试使用after，但它仅适用于 end_date > start_date。当然，我可以使用 添加自定义规则Validator::extend，但我想知道我们是否可以不添加自定义规则。
Is there any way to add negative rule or add >= rule?
有没有办法添加否定规则或添加 >= 规则？
Thanks
谢谢

$validator = Validator::make($data, [
'start_date' => 'required|date',
'end_date' => 'required|date|after_or_equal:start_date',
]);
Use after_or_equal
使用after_or_equal

upgarate to 5.4and you can use after_or_equal see https://laravel.com/docs/5.4/validation#rule-after-or-equal
升级到5.4，您可以使用 after_or_equal 参见 https://laravel.com/docs/5.4/validation#rule-after-or-equal

Actually, you can also use after_or_equaland before_or_equalwhen using at least Laravel version 5.3.31. This may help to avoid having to upgrade to a higher Laravel version.
实际上，您也可以使用after_or_equal和before_or_equal至少在使用 Laravel 版本时5.3.31。这可能有助于避免升级到更高的 Laravel 版本。

Be careful when you set a validation rule after_or_equal:nowand date_formatwith a format without hours, minutes or seconds!
当您设置验证规则after_or_equal:now并且date_format格式没有小时、分钟或秒时要小心！
For example:
例如：
$validationRules = [
'my_time_start' => [
'date_format:Y-m-d',// format without hours, minutes and seconds.
'after_or_equal:now'
]
];
Laravel passing all date fields into the strtotime()function.
Including nowstring.
And strtotime('now')will return a unix timestamp with current minutes, hours and seconds.
Laravel 将所有日期字段传递给strtotime()函数。包括now字符串。而strtotime('now')会返回一个Unix时间戳与当前的分钟，小时，秒。
For example, the today date is 2020-05-03.
When you send a date value 2020-05-03into your script, Laravel will pass 2 values into the strtotime()for compare:
例如，今天的日期是2020-05-03。当您将日期值发送2020-05-03到脚本中时，Laravel 会将 2 个值传递strtotime()给比较：
strtotime('2020-05-03'); // always 1588489200
strtotime('now'); // NOT PREVIOUS VALUE, a different value each second, timestamp including current minutes, hour and seconds.
And you will always fail a validation (exclude a 1 second of the day).
并且您将始终无法通过验证（一天中的 1 秒除外）。
To fix it, you should use:
要修复它，您应该使用：
$validationRules = [
'my_time_start' => [
'date_format:Y-m-d',// format without hours, minutes and seconds.
'after_or_equal:' . date('Y-m-d'), // not 'now' string
]
];
