Export .xslx data using Laravel Excel with parameter - laravel

Question

I want to export data from the database to .xlsx using Laravel-Excel.
I want to pass three parameters to query the data and download into excel file.
I already search and read a few examples but still failed to make the excel file to download.
This is my blade file.
#section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-3"></div>
<div class="col-md-6">
<div class="card">
<div class="card-header">Download Report</div>
<div class="card-body">
<div class="col-md-12" style="margin-bottom:15px">
<select class="form-control" name="plant" id="plant">
<option selected value="All">Please Select Plant</option>
#foreach($plants as $plant)
<option value="{{ $plant->id }}">{{ $plant->name }}</option>
#endforeach
</select>
</div>
<div class="col-md-12" style="">
<div class="input-group input-daterange" align="center">
<input type="text" name="from_date" id="from_date" readonly class="form-control" value="<?php echo date("Y-m-d");?>" />
<div class="input-group-addon" >To</div>
<input type="text" name="to_date" id="to_date" readonly class="form-control" value="<?php echo date("Y-m-d");?>"/>
</div>
</div>
<br>
<div class="col-md-12" align="center">
<button type="button" name="search" id="search" class="btn btn-info btn-block">Download</button>
</div>
</div>
</div>
</div>
<div class="col-md-3"></div>
</div>
</div>
<script type="text/javascript">
$(function() {
var date = new Date();
$('.input-daterange').datepicker({
todayBtn: 'linked',
format: 'yyyy-mm-dd',
autoclose: true
});
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$('#search').click(function(e){
e.preventDefault();
var from_date = $('#from_date').val();
var to_date = $('#to_date').val();
var plant = $('#plant').val();
if(plant != 'All')
{
$.ajax({
url:"{{ route('export') }}",
data:{from_date:from_date, to_date:to_date, plant:plant},
dataType:"json",
})
}
else
{
alert('Please Select Plant');
}
});
});
</script>

This is my function at the controller
public function export(Request $request)
{
return (new DetailReportDownload($request->plant,$request->from_date,$request->to_date))->download('Report Details.xlsx');
}
and This is my Export file
class DetailReportDownload implements FromQuery, WithHeadings
{
use Exportable;
protected $plant,$from,$to;
public function __construct(String $from,String $to,String $plant)
{
$this->plant = $plant;
$this->from = $from;
$this->to = $to;
}
public function headings(): array
{
return [
'plandate',
'workcentre',
'partno',
'prodduration',
'totaldowntime',
'planout',
'cumout',
];
}
public function query()
{
return DB::table('plannings')
->select(DB::raw('plandate, workcentre, partno, prodduration, coalesce(sum(downduration),0) as totaldowntime, planout, cumout'))
->join('prodstatuses', 'plannings.id', '=', 'prodstatuses.id')
->leftJoin('downtimes', 'plannings.id', '=', 'downtimes.plan_id')
->whereBetween('plandate', array($this->from, $this->to))
->where('plant_id',$this->plant)
->where('status','Finished')
->groupBy('plannings.id')
->orderBy('plannings.id');
}
}
I wanted to download excel file from parameter given in blade file.
Thanks in advance for any help

Answer 1

create a provider to add below code & register to app.php file
Sheet::macro('styleCells', function (Sheet $sheet, string $cellRange, array $style) {
$sheet->getDelegate()->getStyle($cellRange)->applyFromArray($style);
});
And create class to download data using parameters,
<?php
namespace App\Modules\User\Http\Exports;
use Illuminate\Contracts\View\View;
use Illuminate\Support\Collection;
use Maatwebsite\Excel\Concerns\FromView;
use Maatwebsite\Excel\Concerns\ShouldAutoSize;
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Events\AfterSheet;
/**
* Class ExportUsers
* #package App\Exports
*/
class ExportUsers implements FromView, ShouldAutoSize, WithEvents
{
protected $plannings;
/**
* ExportUsers constructor.
* #param Collection $plannings
*/
public function __construct(Collection $plannings) {
$this->plannings = $plannings;
}
/**
* #return View
*/
public function view() : View {
return view('plannings_list', [
'plannings' => $this->plannings,
]);
}
/**
* #return array
*/
public function registerEvents() : array {
return [
AfterSheet::class => function (AfterSheet $event) {
$this->createStyle($event, 'A1:N1', 9);
$event->sheet->styleCells(
'A1:N1',
[
'font' => [
'bold' => true,
]
]
);
},
];
}
/**
* #param $event
* #param $cell
* #param $size
* #throws \PhpOffice\PhpSpreadsheet\Exception
*/
private function createStyle($event, $cell, $size) {
/** #var AfterSheet $event */
$event->sheet->getDelegate()->getStyle($cell)->getFont()->setSize($size);
}
}
add this code to controller
private function downloadCsv($exportCsvList) {
return Excel::download(new ExportUsers($exportCsvList),
'students.xlsx');
}
