<p>如何檢查資料庫中是否已存在給定時間段內特定使用者的工作時間。因此,當工作時間與給定日期和時間重疊時,函數應傳回 true。我試過了,但這不起作用。 </p> <pre class="brush:php;toolbar:false;">function checkExistingWorkingHours($user_id, $start_date, $start_time, $end_date, $end_time) { // dd($user_id . " " . $start_date . " " . $start_time . " " . $end_date . " " . $end_time); $startDateTime = Carbon::parse($start_date . ' ' . $start_time); $endDateTime = Carbon::parse($end_date . ' ' . $end_time); $overlapExists = WorkingHour::where('user_id', $user_id) ->where(function ($query) use ($startDateTime, $endDateTime) { $query->where(function ($query) use ($startDateTime, $endDateTime) { // Check for overlap where the start_datetime is between existing start_datetime and end_datetime $query->where(function ($query) use ($startDateTime, $endDateTime) { $query->where('start_date', '=', $startDateTime->format('Y-m-d')) ->where('start_time', '<', $endDateTime->format('H:i')) ->where('end_date', '=', $startDateTime->format('Y-m-d')) ->where('end_time', '>', $startDateTime->format('H:i')); })->orWhere(function ($query) use ($startDateTime, $endDateTime) { $query->where('start_date', '<', $startDateTime->format('Y-m-d')) ->where('end_date', '=', $startDateTime->format('Y-m-d')) ->where('end_time', '>', $startDateTime->format('H:i')); }); })->orWhere(function ($query) use ($startDateTime, $endDateTime) { // Check for overlap where the end_datetime is between existing start_datetime and end_datetime $query->where(function ($query) use ($startDateTime, $endDateTime) { $query->where('start_date', '=', $endDateTime->format('Y-m-d')) ->where('end_date', '>=', $endDateTime->format('Y-m-d')) ->where('start_time', '<', $endDateTime->format('H:i')); })->orWhere(function ($query) use ($startDateTime, $endDateTime) { $query->where('start_date', '<=', $startDateTime->format('Y-m-d')) ->where('end_date', '>=', $endDateTime->format('Y-m-d')); }); }); })->exists(); return $overlapExists; }</pre> <p>當我使用以下資料測試函數時,它說存在重疊,即使沒有重疊。 </p> <p>檢查現有工作時間(1, 2023-06-01, 00:15, 2023-06-01, 03:00);</p> <p>資料庫中的值是 2023-06-01 03:30 到 11pm。 </p>

嘗試使用這個

$start = Carbon::parse($start_date . ' ' . $start_time)->stratOfDay();
$end = Carbon::parse($end_date . ' ' . $end_time)->endOfDay();
$overlapExists = WorkingHour::where('user_id', $user_id)->whereBetween('your column',[$start , $end])->exists();

根據geertjanknapen的評論回答:

$period = CarbonPeriod::create("$start_date $start_time", "$end_date $end_time");
$start = Carbon::create("$to_check->start_date $to_check->start_time");
$end = Carbon::create("$to_check->end_date $to_check->end_time");


if ($period->overlaps($start, $end)) {
    return redirect()->back()->withInput()->with('error',"Time is overlapping!");
