How to add months dynamically which is stored in database as a header in excel file while exporting using laravel? - laravel

Question

Suppose I have items in database which is stored from an Excel file. All the items should be below the header of the months. I have also stored months from the file in the database. So, I want those months to be the header of those items and it's related records. In simple words, I want the header to be dynamic. This is what I have done.
I have tried many code scripts but nothing works. Like Laravel, Excel etc. Can anyone suggest me a good approach?
public function test(){
$data = Item::where('category_id',7)->get()->toArray();
$data2 = month::all();
$itemsArray[] = ['Category Id','Item Name','Created At','Updated At'];
foreach ($data as $value) {
// dd($value);
$itemsArray[] = array(
'Category Id' => $value['category_id'],
'Item Name' => $value['name'],
'Created At' => $value['created_at'],
'Updated At' => $value['updated_at'],
);
}
// Generate and return the spreadsheet
Excel::create('Items', function($excel) use ($itemsArray) {
// Set the spreadsheet title, creator, and description
$excel->setTitle('Items');
// Build the spreadsheet, passing in the items array
$excel->sheet('Items', function($sheet) use ($itemsArray) {
$cellRange = 'A1:D1';
// $spreadsheet->getActiveSheet()->getStyle('A1:D4')
// ->getAlignment()->setWrapText(true);
$sheet->getStyle($cellRange)->getFont()->setBold( true );
$sheet->getStyle($cellRange)->getFont()->setSize( '15' );
$sheet->setBorder($cellRange, 'thick' );
$sheet->getStyle($cellRange)->applyFromArray(array(
'fill' => array(
// 'type' => PHPExcel_Style_Fill::FILL_SOLID,
'color' => array('rgb' => 'A5D9FF')
)
));
$sheet->fromArray($itemsArray, null, 'A1', false, false);
});
$excel->setCreator('Laravel')->setCompany('Dev505');
$excel->setDescription('Items file');
})->download('xlsx');
}
I need help for getting the actual result.

Answer 1

Akhtar i suggest use to kindly install the Carbon package
https://carbon.nesbot.com/docs/
Try by updating the below code.
$data = Item::where('category_id',7)->get(); // removed toArray()
$data2 = month::all();
$itemsArray[] = ['Category Id','Item Name','Created At','Updated At'];
foreach ($data as $key=>$value) {
$itemsArray[] = array(
'month' => Carbon::now()->addMonth($key)->format('m-Y');
'Category Id' => $value['category_id'],
'Item Name' => $value['name'],
'Created At' => $value['created_at'],
'Updated At' => $value['updated_at'],
);
}

This is the actual code which I have used for excel file. I have solved my problem. Thanks and yeah I am posting this code, if anyone can get help from it.
public function export(){
$data = Category::all();
foreach ($data as $value) {
$value['items'] = Item::where('category_id',$value['id'])->get();
foreach ($value['items'] as $vl) {
$vl['record'] = Record::where('item_id',$vl['id'])->get();
}
}
$data2 = month::pluck('id','month');
foreach ($data2 as $key => $value) {
$m[] = $key;
}
array_unshift($m, 'Categories'); //Insert new element at the start of array
array_push($m, 'Total');
$itemsArray[] = $m;
foreach ($data as $value) {
$itemsArray[] = array(
$itemsArray[0][0] => $value['name'],
// $itemsArray[0][13] => 'Total',
);
foreach ($value['items'] as $val) {
$records_array = [];
$i = 0;
foreach ($val['record'] as $val5) {
$recordval = $val5['value'];
$records_array[$i] = $val5['value'];
$i++;
}
$itemsArray[] = array(
$itemsArray[0][0] => $val['name'],
$itemsArray[0][1] => $records_array[0],
$itemsArray[0][2] => $records_array[1],
$itemsArray[0][3] => $records_array[2],
$itemsArray[0][4] => $records_array[3],
$itemsArray[0][5] => $records_array[4],
$itemsArray[0][6] => $records_array[5],
$itemsArray[0][7] => $records_array[6],
$itemsArray[0][8] => $records_array[7],
$itemsArray[0][9] => $records_array[8],
$itemsArray[0][10] => $records_array[9],
$itemsArray[0][11] => $records_array[10],
$itemsArray[0][12] => $records_array[11],
// $itemsArray[0][13] => 'Total',
);
}
}
// Generate and return the spreadsheet
Excel::create('Items', function($excel) use ($itemsArray) {
// Set the spreadsheet title, creator, and description
$excel->setTitle('Items');
// Build the spreadsheet, passing in the items array
$excel->sheet('Items', function($sheet) use ($itemsArray) {
$cellRange = 'A1:M1';
$sheet->getStyle($cellRange)->getFont()->setBold( true );
$sheet->getStyle($cellRange)->getFont()->setSize( '12' );
$sheet->setBorder($cellRange, 'thin' );
$sheet->getStyle($cellRange)->applyFromArray(array(
'fill' => array(
// 'type' => PHPExcel_Style_Fill::FILL_SOLID,
'color' => array('rgb' => 'A5D9FF')
)
));
$sheet->fromArray($itemsArray, null, 'A1', false, false);
});
$excel->setCreator('Laravel')->setCompany('Dev505');
$excel->setDescription('Items file');
})->download('xlsx');
}
