Laravel excel export how to export conditional data? - laravel

Question

I am trying to export partial data from my table not all data, I am using Maatwebsite plugin
I have tried below code in controller
public function report(Request $request)
{
$sdate = $request->query('sdate');
$edate = $request->query('edate');
$report = Report::whereDate('created_at', '>=', $sdate)
->whereDate('created_at', '<=', $edate)
->get();
return Excel::download($report, 'report.xlsx');
}
In this time I am getting empty excel file.
I am able to get all data after creating app/export
like below
app/export/ReportExport.php
public function collection()
{
return Report::all();
}
but how I can I do it in controller ? or how can I sent $report data controller to collection ?

Answer 1

You can use the FromQuery concern provided by the package.
namespace App\Exports;
use App\Report;
use Maatwebsite\Excel\Concerns\FromQuery;
use Maatwebsite\Excel\Concerns\Exportable;
class ReportExport implements FromQuery
{
use Exportable;
public function __construct($start, $end)
{
$this->start = $start;
$this->end = $end;
}
public function query()
{
return Report::query()->whereDate('created_at', '>=', $this->start)
->whereDate('created_at', '<=', $this->end);
}
}
Then from you controller, you can call it
return (new ReportExport($sdate, $edate))->download('report.xlsx');
I have not tested the code. So apologies if I made a mistake. You can refer to official documentation.
There are also other methods of exporting which you can find from the documentation.

Answer 2

you can do it by doing this way.
Step 1: in your controller
bind $request in Report-Export Class. add code in method where you are calling export excel.
return Excel::download(new ReportExport($request), 'report.xlsx');
step 2:
protected $request;
public function __construct($request)
{
$this->request = $request;
}
public function collection()
{
$request = $this->request ;
return User::where('customer_id',$request->cId)->get();
}
