In Laravel 9, verify that two time fields span cannot exceed 3 months

1. The request parameters are as follows, you need to ensure that the shipping_at_gmt_end cannot exceed the shipping_at_gmt_start for 3 months. as shown in Figure 1

Figure 1

{
    "filter": {
        "shipping_at_gmt_start": "2024-02-08T16:00:00.000Z",
        "shipping_at_gmt_end": "2025-02-08T17:00:00.000Z"
    }
}

2. Use closure to customize the verification rules, based on Carbon. After adding SHIPPING_AT_GMT_START for 3 months before comparing with SHIPPING_AT_GMT_END, if SHIPPING_AT_GMT_END is still later than Shipping_at_gmt_start adds the value after 3 months, and the verification fails.

'filter.shipping_at_gmt_start' => 'date',
'filter.shipping_at_gmt_end' => [
	'date',
	'after_or_equal:filter.shipping_at_gmt_start',
	function ($attribute, $value, $fail) use ($params) {
		$startDate = Carbon::parse($params['filter']['shipping_at_gmt_start'])->addMonths(3);
		$endDate = Carbon::parse($value);
		if ($endDate->isAfter($startDate)) {
			$fail('交运时间结束与交运时间开始的跨度不可超过3个月');
		}
	},
],

3. When the Shipping_AT_GMT_START does not exist, the error is reported: undefined array key \”Shipping_at_gmt_start\”, if SHIPPING_AT_GMT_START does not exist, then SHIPPING_AT_GMT_END is not validated. as shown in Figure 2

Figure 2

'filter.shipping_at_gmt_start' => 'date',
'filter.shipping_at_gmt_end' => [
	// 如果交运时间开始不存在，则不验证，防止报错：Undefined array key "shipping_at_gmt_start"
	'exclude_without:filter.shipping_at_gmt_start',
	'date',
	'after_or_equal:filter.shipping_at_gmt_start',
	function ($attribute, $value, $fail) use ($params) {
		$startDate = Carbon::parse($params['filter']['shipping_at_gmt_start'])->addMonths(3);
		$endDate = Carbon::parse($value);
		if ($endDate->isAfter($startDate)) {
			$fail('交运时间结束与交运时间开始的跨度不可超过3个月');
		}
	},
],

4. When “SHIPPING_AT_GMT_START”: “2024-01-31T16:00:00.000Z”, “Shipping_at_gmt_end”: “2024-05-01t16:00:00.000z” The verification is successful. When “SHIPPING_AT_GMT_START”: “2024-01-31T16:00:00.000Z”, “Shipping_at_GMT_END”: “2024-05-01T16:01:00.000z” Validation failed. in line with expectations. 2024-01-31 After adding 3 months, its value is 2024-05-01, because 2024-04 is only 30 days.
