working with Laravel 10 backend and I have following dropdown for select zone name and existing system show some zone name from table. but I need show –select zone– as the default value of the dropdown when the page load.
zone.blade.php
<form action="{{request()->fullUrl()}}" id="zoneSubmitForm" class="pb-1">
<div class="">
<select class="js-select-custom min-w-200 h-35" name="zone_id" id="selectZone">
@if(count($zones)>0)
@foreach($zones as $key =>$zone)
<option value="{{$zone->id}}"
{{request('zone_id') == $zone->id ? "selected" :""}} data-show-shield="{{ in_array($zone->id, $safetyAlertZones) ? 'true' : '' }}">{{$zone->name}}</option>
@endforeach
@else
<option selected disabled>{{translate("zone_not_found")}}</option>
@endif
</select>
</div>
</form>
<script>
$('#selectZone').on('change', function () {
$('#zoneSubmitForm').submit();
});
</script>
ZonemanageController
public function fleetMap(?Request $request, $type = null)
{
$zones = $this->zoneService->getBy(relations: ['tripRequest.safetyAlerts']);
$safetyAlertZones = $zones->filter(function ($zone) {
return $zone->tripRequest->contains(function ($tripRequest) {
return $tripRequest->safetyAlerts->where('status', PENDING)->isNotEmpty();
});
})->pluck('id')->toArray();
$safetyAlertCount = $this->safetyAlertService->getBy(criteria: ['status' => PENDING])->count();
if (array_key_exists('zone_id', $request->all()) && $request['zone_id']) {
$zone = $this->zoneService->findOne(id: $request['zone_id']);
} else {
$zone = count($zones) ? $this->zoneService->findOne(id: $zones[0]->id) : null;
}
$safetyAlertLatestUserRoute = $safetyAlertCount > 0 ? $this->safetyAlertService->safetyAlertLatestUserRoute() : 'javascript:void(0)';
$safetyAlert = $this->safetyAlertService->findOneBy(criteria: ['status' => PENDING], relations: ['sentBy'], orderBy: ['created_at' => 'desc']);
$safetyAlertUserId = $safetyAlert?->sentBy?->id ?? null;
// Calculate center lat/lng
$latSum = 0;
$lngSum = 0;
$totalPoints = 0;
$polygons = $zone ? json_encode([formatCoordinates(json_decode($zone?->coordinates[0]->toJson(), true)['coordinates'])]) : json_encode([[]]);
if ($zone) {
foreach (formatCoordinates(json_decode($zone?->coordinates[0]->toJson(), true)['coordinates']) as $point) {
$latSum += $point->lat;
$lngSum += $point->lng;
$totalPoints++;
}
}
$centerLat = $latSum / ($totalPoints == 0 ? 1 : $totalPoints);
$centerLng = $lngSum / ($totalPoints == 0 ? 1 : $totalPoints);
if ($zone) {
$data = $this->fleetCommon($type, $zone, $request->all());
$drivers = $data['drivers'] ?? [];
$customers = $data['customers'] ?? [];
$markers = $data['markers'];
return view('adminmodule::fleet-map', compact('drivers', 'customers', 'zones', 'safetyAlertZones', 'safetyAlertCount', 'safetyAlertLatestUserRoute', 'safetyAlertUserId', 'type', 'markers', 'polygons', 'centerLat', 'centerLng'));
}
$drivers = [];
$customers = [];
$markers = json_encode([[]]);
return view('adminmodule::fleet-map', compact('drivers', 'customers', 'zones', 'safetyAlertZones', 'safetyAlertCount', 'safetyAlertLatestUserRoute', 'safetyAlertUserId', 'type', 'markers', 'polygons', 'centerLat', 'centerLng'));
}
how could I select as default value –select zone– when blade file load the zone name?
