laravel 如何验证跨越午夜的两个值之间的时间(15：00 > 时间 > 01：00)

我终于找到了解决办法.

我使用命令"php artisan make:rule CrossMiddNightTimeValidation"创建了一个规则

在创建的文件中

<?php

namespace App\Rules;

use Illuminate\Contracts\Validation\Rule;

class CrossMidnightTimeValidation implements Rule
{
    private $starting_time,$end_time;

    public function __construct($starting_time, $end_time)
    {
        $this->starting_time = $starting_time;
        $this->end_time = $end_time;

    }

    /**
     * Determine if the validation rule passes.
     *
     * @param  string  $attribute
     * @param  mixed  $value
     * @return bool
     */
    public function passes($attribute,  $value)
    {
        return ($value >= $this->starting_time && $value <= now()->endOfDay()->format('H:i'))
            || (($value >= now()->startOfDay()->format('H:i') && $value <= $this->end_time));
    }

    /**
     * Get the validation error message.
     *
     * @return string
     */
    public function message()
    {
        return 'Invalid Time (out of the shift time).';
    }
}

为了我的规则.

public function rules()
    {
        $shift = Shift::find($this->shift);
        $rules = [
            'date' => 'required|date|date_format:Y-m-d',
            'shift' => 'required|exists:shifts,id,user_id,' . auth()->id(),
            'attendance' => 'required|array',
            'attendance.*.employee_id' => 'required|exists:employees,id,user_id,' . auth()->id(),
        ];
        if ($shift->across_midnight) {
            foreach ($this->attendance as $key => $value) {
                $rules['attendance.' . $key . '.time_in'] = [Rule::requiredIf($this->has('attendance.' . $key . '.present')), 'date_format:H:i', 'nullable', new CrossMidnightTimeValidation($shift?->starting_time, $shift?->leaving_time)];
                $rules['attendance.' . $key . '.time_out'] = [Rule::requiredIf($this->has('attendance.' . $key . '.present')), 'date_format:H:i', 'nullable', new CrossMidnightTimeValidation($shift?->starting_time, $shift?->leaving_time)];
            }
        }
        else {
            foreach ($this->attendance as $key => $value) {
                $rules['attendance.' . $key . '.time_in'] = [Rule::requiredIf($this->has('attendance.' . $key . '.present')), 'date_format:H:i', 'nullable', 'before_or_equal:attendance.' . $key . '.time_out', 'after_or_equal:' . $shift?->starting_time];
                $rules['attendance.' . $key . '.time_out'] = [Rule::requiredIf($this->has('attendance.' . $key . '.present')), 'date_format:H:i', 'nullable', 'before_or_equal:' . $shift?->leaving_time, 'after_or_equal:' . $shift?->starting_time];
            }
        }
        return $rules;
    }
