PHPExcel converting from a database to xlsx

Question

I have next code :

    <?php
        require_once 'PHPExcel/Classes/PHPExcel.php';

        $excel->getProperties()->setLastModifiedBy('Boris Jelic');
        $excel->getProperties()->setTitle('Orders');
        $excel->removeSheetByIndex(0);

        $list->getColumnDimension('F')->setWidth(20);
        $list->getColumnDimension('G')->setWidth(15);
        $list->getColumnDimension('H')->setWidth(40);
        $list->getColumnDimension('I')->setWidth(40);
        $list->setCellValue('A1', 'Tijd');
        $list->setCellValue('B1', 'Shop');
        $list->setCellValue('C1', 'Products');
        $list->setCellValue('D1', 'Naam en voornaam');
        $list->setCellValue('E1', 'Adres');

        $writer = new PHPExcel_Writer_Excel2007($excel);
        if($writer->save('files/users.xlsx')){
            echo "Konvertovan je."; 
        }
   ?>

I save results in an xlsx file, everything works fine, but i'm trying to get a little bit different display of the contents within my excel file.

Now I get something like this withing my excel file(photo 1)

But I would like to get something like this (photo 2)

Thus I want to do something like group by the shops. If one user has ordered more products from the same shop that they all displayed within one row in the excel file, not like now, it is created a new row for each product.

UPDATED When i add GROUP_CONCAT(producten.naam SEPARATOR '\r') as prodNaam and GROUP BY korisnici.id I get than the right result in my excel file. Exactly like op the photo 2. But then I have the next problem. I can't get order_details.aantal value for each product, I get than values for only first product for each user. But if I put GROUP BY order_details.id then I get the right order_details.aantal value for each product but then I get my excel file like on the photo 1.

Answer 1

You can do something like this

$userHolder = '';
$shopHolder = ''; 
while ($row = mysqli_fetch_assoc($rezOrders)){

  if($userHolder != $value['user']){
    $list->setCellValue('A'.$rowcounter, $row['korNaam']);
    $userHolder = $value['user'];
    $shopHolder = '';
  }

  if($shopHolder != $value['shop']){
    $list->setCellValue('B'.$rowcounter, $row['shopNaam']);
    $shopHolder = $value['shop'];
  }
  $list->setCellValue('C'.$rowcounter, $row['prodNaam']);
  $rowcounter++;
}

Answer 2

One simple way to do this would be to use GROUP BY and GROUP_CONCAT in you SQL statement.

In particular, group your query by the fields that represent "User" and "Shop", and instead of simply selecting producten.naam as prodNaam, use GROUP_CONCAT(producten.naam, '\r').
