PHPExcel 从数据库转换为 xlsx

Question

我有下一个代码：

    <?php
        require_once 'PHPExcel/Classes/PHPExcel.php';
        include "PHPExcel/Classes/PHPExcel/Writer/Excel2007.php"; 
        session_start();
        include("config.php");
        global $kon;
        ob_start();
        $excel = new PHPExcel;
        $excel->getProperties()->setCreator('Boris Jelic');
        $excel->getProperties()->setLastModifiedBy('Boris Jelic');
        $excel->getProperties()->setTitle('Orders');
        $excel->removeSheetByIndex(0);


        $cols = array('tijd' => 'A', 'shop' => 'B', 'products' => 'C', 'naam' => 'D', 'adres' => 'E', 'gemeente' => 'F', 'telefoonnummer' => 'G', 'email' => 'H', 'leeggoed' => 'I');
        $list = $excel->createSheet();
        $list->setTitle('Users');
        $list->getColumnDimension('A')->setWidth(20);
        $list->getColumnDimension('B')->setWidth(25);
        $list->getColumnDimension('C')->setWidth(40);
        $list->getColumnDimension('D')->setWidth(40);
        $list->getColumnDimension('E')->setWidth(40);
        $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');
        $list->setCellValue('F1', 'Gemeente');
        $list->setCellValue('G1', 'Telefoonnummer');
        $list->setCellValue('H1', 'Email');
        $list->setCellValue('I1', 'Leeggoed');


        //za background
        $excel->getActiveSheet()->getStyle('A1:I1')->getFill()

        ->getStartColor()->setARGB('FFE8E5E5');

        //stavljamo naslove bold
        $excel->getActiveSheet()->getStyle('A1:I1')->getFont()->setBold(true);

        //povecavamo velicinu slova
        $excel->getActiveSheet()->getStyle('A1:I1')->getFont()->setSize(13);


        //moramo prvo uzeti sve orders sa statusom 1
        $rezOrders = mysqli_query($kon, "SELECT 
                                         shops.naam as shopNaam,

                                         INNER JOIN product_shop_tt ON order_details.product_shop_tt_id = product_shop_tt.id

                                         WHERE orders.status = 1 GROUP BY korisnici.id");

        $rowcounter = 2;

        while ($row = mysqli_fetch_assoc($rezOrders)){


           $prod_id = $row['prodID'];
           $prodKol = $row["prodNaam"] . " -- Aantal : " . $row["kolicina"] . "x";
           echo "Product + quantity : " . $prodKol . "<br />";


          //Da uzmemo aantal za taj product


          /*echo "Product i kolicina : " . $redAan["productNaam"] . " - " . $redAan["kolicina"] . "<br />";*/
          $tijd = $row["tijd"];
          $ime = $row["korNaam"] . " " . $row["korPrez"];
          $email = $row["korMail"];
          $telNummer = $row["broj"];
          $gemeente = $row["gemeente"];
          $adresa = $row["adres"] . " " . $row["hn"];

          $list->setCellValue('A'.$rowcounter, $tijd);
          $list->setCellValue('B'.$rowcounter, $row['shopNaam']);
          $list->setCellValue('C'.$rowcounter, $prodKol."\r");

        }


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

我将结果保存在一个 xlsx 文件中，一切正常，但我试图在我的 excel 文件中显示一些不同的内容。

现在我的 excel 文件得到了类似的东西（照片 1）

但我想要这样的东西（照片2）

所以我想做一些类似按商店分组的事情。如果一个用户从同一家商店订购了更多产品，它们都显示在 excel 文件的一行中，而不像现在，它会为每个产品创建一个新行。

已更新 当我将 GROUP_CONCAT(producten.naam SEPARATOR '\r') 添加为 prodNaam 和 GROUP BY korisnici.id 我得到的结果比 excel 文件。与照片 2 完全一样。但是我遇到了下一个问题。我无法获得每个产品的 order_details.aantal 价值，我只能获得每个用户的第一个产品的价值。但是如果我把 GROUP BY order_details.id 然后我得到每个产品的正确 order_details.aantal 值但是然后我得到我的 excel 文件就像照片 1.

Answer 1

一个简单的方法是在 SQL 语句中使用 GROUP BY 和 GROUP_CONCAT。

特别是，按代表 "User" 和 "Shop" 的字段对查询进行分组，而不是简单地选择 producten.naam 作为 prodNaam，使用 GROUP_CONCAT(producten.naam, '\r').

Answer 2

你可以这样做

$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++;
}
