在 foreach 循环内按开始时间对数据进行排序

Question

我想对 foreach 循环内的开始时间数据进行排序。

这是我的控制器代码：

private function getPatientList($search = null)
    {
        return Appointment::select('id', 'hospital_id', 'patient_id', 'serial_no', 'doctor_schedule_detail_id')
            ->whereHas('patient', function ($query) use ($search) {
                $query->select('id', 'name', 'mobile_no', 'gender');
                if ($search) {
                    $query->where(function ($q) use ($search) {
                        $q->where('name_hash', hash('sha256', $search))
                            ->orWhere('mobile_no_hash', hash('sha256', $search));
                    });
                }
            })->where('doctor_id', auth()->user()->doctor->id)
            ->where('hospital_id', auth()->user()->doctor->current_hospital_id)  
            ->where('status', '!=', 'Cancelled')
            ->whereDate('reporting_time', date('Y-m-d'))
            ->orderBy('reporting_time')->get()
            ->groupBy('doctor_schedule_detail_id')->all();
    }

型号中：

public function doctorScheduleDetail()
    {
        return $this->belongsTo(DoctorScheduleDetail::class);
    }

预约有 doctor_schedule_detail_id 列以及与 doctor_schedule_details 表的关系。在 doctor_schedule_details 表中有 start_time 列。

我认为：

@foreach ($appointments as $doctorScheduleId => $appointmentsGroup)
        
    <div class="row row-cards patient-list mb-3">
        <h4 class="mb-0"><span class="">Slot {{ $loop->iteration }}</span> [{{ date("g:i A",
            strtotime($appointmentsGroup[0]->doctorScheduleDetail->start_time)) }} - {{
            date("g:i A", strtotime($appointmentsGroup[0]->doctorScheduleDetail->end_time)) }}]</h4>
        @foreach ($appointmentsGroup as $appointment)
            <div class="col-sm-6 col-lg-3">{{ $appointment?->patient?->name }}</div>
            --------
        @endforeach
    </div>
@endforeach

在这里，我循环遍历分组数据。我想根据 $appointmentsGroup[0]->doctorScheduleDetail->start_time 进行排序 - 它位于第一个 foreach 中。

我该怎么做？

我试过了，但没用

private function getPatientList($search = null)
    {
        return Appointment::select('id', 'hospital_id', 'patient_id', 'serial_no', 'doctor_schedule_detail_id')
            ->whereHas('patient', function ($query) use ($search) {
                $query->select('id', 'name', 'mobile_no', 'gender');
                if ($search) {
                    $query->where(function ($q) use ($search) {
                        $q->where('name_hash', hash('sha256', $search))
                            ->orWhere('mobile_no_hash', hash('sha256', $search));
                    });
                }
            })->where('doctor_id', auth()->user()->doctor->id)
            ->where('hospital_id', auth()->user()->doctor->current_hospital_id)  
            ->where('status', '!=', 'Cancelled')
            ->whereDate('reporting_time', date('Y-m-d'))
            ->orderBy('reporting_time')->get()
            ->groupBy('doctor_schedule_detail_id')
            ->map(function ($appointmentsGroup) {
                return $appointmentsGroup->sortBy(function ($appointment) {
                    return strtotime($appointment->doctorScheduleDetail->start_time);
                });
            })
            ->all();
    }

Answer 1

您已将排序应用于每个组内的约会，而不是对组本身进行排序。

因此，您可以做的是，分组后，根据与每个组中第一个约会关联的

doctorScheduleDetail

的 start_time 对组进行排序。

也渴望加载

doctorScheduleDetail

。

private function getPatientList($search = null)
{
    $appointments = Appointment::with('doctorScheduleDetail')
        ->select('id', 'hospital_id', 'patient_id', 'serial_no', 'doctor_schedule_detail_id')
        ->whereHas('patient', function ($query) use ($search) {
            $query->select('id', 'name', 'mobile_no', 'gender');
            if ($search) {
                $query->where(function ($q) use ($search) {
                    $q->where('name_hash', hash('sha256', $search))
                        ->orWhere('mobile_no_hash', hash('sha256', $search));
                });
            }
        })
        ->where('doctor_id', auth()->user()->doctor->id)
        ->where('hospital_id', auth()->user()->doctor->current_hospital_id)  
        ->where('status', '!=', 'Cancelled')
        ->whereDate('reporting_time', date('Y-m-d'))
        ->orderBy('reporting_time')
        ->get()
        ->groupBy('doctor_schedule_detail_id');

    $sortedAppointments = $appointments->sortBy(function ($appointmentsGroup) {
        return $appointmentsGroup->first()->doctorScheduleDetail->start_time;
    });

    return $sortedAppointments->all();
}
