如何根据服务时间禁用时间段？

Question

我只想根据我的营业时间和阻止或禁用那些时间段计算时间段列表预约。

我已经解决了我的问题，卡在最后一个任务上，请在下面提及。

My Service Duration = 60min.
My Today Busines Hours:
start time - 10:00 AM
end time - 3:00 PM

我已根据我今天的营业时间生成了 15 分钟的时隙列表：

$start = strtotime('10:00 AM');
$end = strtotime('3:00 PM');
for( $i = $start; $i <= $end; $i += (60*15)) 
{
    $slotlist[] = date('g:iA', $i);
}

//output
10:00AM
10:15AM
10:30AM
10:45AM
11:00AM
11:15AM
11:30AM
11:45AM
12:00PM
12:15PM
12:30PM
12:45PM
1:00PM
1:15PM
1:30PM
1:45PM
2:00PM
2:15PM
2:30PM
2:45PM
3:00PM

现在我已经预约了 3 个约会

约会 |开始时间到结束时间

---

Appointment-1 : 10:00 AM to 11:00 AM (根据我的服务时长60分钟)
预约 2：上午 11:15 至下午 12:15
预约 3：下午 1:00 至下午 2:00

---

//array of all appointment start_time
$appointment_start_time = array('10:00AM','11:15AM','1:00PM');

现在禁用那些已经预约的时间段

foreach($slotlist as $single)
{
    if(in_array($single, $appointment_start_time))
    {
        echo "<input name=start_time type='radio' disabled  value='$single' />".$single; echo "<br>";

        $time = $single;                                                
        $event_length = 60-15;          // 60 is time duration                              
        $timestamp = strtotime("$time");                                
        $endtime = strtotime("+$event_length minutes", $timestamp);     
        $next_time = date('g:i A', $endtime);                       

        //calculate between slots (start-end time)
        $start = strtotime($single);
        $end = strtotime($next_time);
            for( $i = $start; $i <= $end; $i += (60*15)) 
            {
                $list2[] = date('g:iA', $i);
            }
    }
    else
    {   
        if(in_array($single, $list2))
        {
            echo "<input name=start_time type='radio' disabled  value='$single' />".$single; echo "<br>";
        }
        else
        {   

            echo "<input name=start_time type='radio'  value='$single' />".$single; echo "<br>";
        }
    }

}

//output
10:00AM -disabled
10:15AM -disabled
10:30AM -disabled
10:45AM -disabled
11:00AM
11:15AM -disabled
11:30AM -disabled
11:45AM -disabled
12:00PM -disabled
12:15PM
12:30PM
12:45PM
1:00PM -disabled
1:15PM -disabled
1:30PM -disabled
1:45PM -disabled
2:00PM
2:15PM
2:30PM
2:45PM
3:00PM

现在要做的最后一个任务， 如何删除那些不符合服务持续时间的时间段，例如：

11:00AM (single slot b/w 2 appointment, cover only 15min)

12:15PM -
12:30PM -(3 slot b/w 2 appointment, cover only 45min)
12:45PM -

Answer 1

试试这个： 1.将第一个时隙与$appointment_start_time[0]比较，如果第一个时隙> $appointment_start_time[0]-60min，则禁用该时隙直到$appointment_start_time[0]。

2.比较 $appointment_start_time[1] 和 $appointment_start_time[0]，如果持续时间 > 2 小时（您的服务持续时间 X 2），禁用 $appointment_start_time[0] 和 $appointment_start_time[1] 之间的时间段

3.比较 $appointment_start_time[2] 和 end-time，如果 end-time-120

两天过去了，我让这件事成为可能

$slottimes = 15;
$duration = 60; 
$business_start = '10:00AM';
$business_end = '3:00PM';

    for( $i = $start; $i <= $end; $i += (60*$slottimes)) 
    {
        $slotlist[] = date('g:iA', $i);

$previoustime = NULL;

foreach($slotlist as $single)

    if(in_array($single, $appstarttime))
