Laravel with Maatwebsite - php

Question

I want to change the name of the column heading.
How do you do?
This is the code in the controller:
public function excelterima($nm_perusahaan){
if($user = Auth::user()->admin == 2){
$users = Mstbeasiswa::select('NO_ANGGOTA', 'NM_ANGGOTA', 'GOLONGAN', 'NPK', 'CABANG', 'NM_ANAK', 'NM_SKL', 'id')
->where('flag_terima', '1')
->where('NM_PERUSAHAAN', $nm_perusahaan)
->orderBy('id', 'asc')
->get()->toArray();
//work on the export
Excel::create($nm_perusahaan, function($excel) use ($users){
$excel->sheet('sheet 1', function($sheet) use ($users)
{
$sheet->fromArray($users);
ob_end_clean();
});
})->download('xlsx');
return redirect('/beasiswaditerima');
}else{
return redirect('/home');
}
}
output current:

By default the fromArray() method of LaravelExcelWorksheet instance will auto-generate the heading for you based on the given array keys. In order to disable this auto-generation, you need to pass false to the fifth parameter (the $headingGeneration). Here's the fromArray() method signature for your reference:
public function fromArray($source = null, $nullValue = null, $startCell = 'A1', $strictNullComparison = false, $headingGeneration = true)
You can use the row() method to add a custom heading. Using your code example, now the code should look like this:
$users = Mstbeasiswa::select('NO_ANGGOTA', 'NM_ANGGOTA', 'GOLONGAN', 'NPK', 'CABANG', 'NM_ANAK', 'NM_SKL', 'id')
->where('flag_terima', '1')
->where('NM_PERUSAHAAN', $nm_perusahaan)
->orderBy('id', 'asc')
->get()
->toArray();
Excel::create($nm_perusahaan, function ($excel) use ($users) {
$excel->sheet('sheet 1', function ($sheet) use ($users) {
// Set your custom header.
$sheet->row(1, ['COL1', 'COL2', 'COL3', 'COL4', 'COL5', 'COL6', 'COL7', 'COL8']);
// Set the data starting from cell A2 without heading auto-generation.
$sheet->fromArray($users, null, 'A2', false, false);
});
})->download('xlsx');
Or you can actually just keep the fromArray() method calling, but later replace the auto-generated header with row() method like so:
$excel->sheet('sheet 1', function ($sheet) use ($users) {
$sheet->fromArray($users);
// Replace the header, but this should come after fromArray().
$sheet->row(1, ['COL1', 'COL2', 'COL3', 'COL4', 'COL5', 'COL6', 'COL7', 'COL8']);
});
Hope this help!
