我正在使用phpexcel，但是从数据库中获取结果我遇到了问题。

我有下一个代码：

    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()
->setFillType(PHPExcel_Style_Fill::FILL_SOLID)
->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, 
                                 GROUP_CONCAT(producten.naam SEPARATOR '\r') as prodNaam, GROUP_CONCAT(producten.id SEPARATOR '\r') as prodID,

                                 INNER JOIN order_details ON order_details.order_id = orders.id
                                 INNER JOIN product_shop_tt ON order_details.product_shop_tt_id = product_shop_tt.id

                                 INNER JOIN shops ON shops.id = product_shop_tt.shop_id 
                                 WHERE orders.status = 1 GROUP BY korisnici.id");

$rowcounter = 2;

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


    $prod_id = $row['prodID'];

   $rez = mysqli_query(
                $kon, 
                "
                SELECT producten.naam as prodNaam

  $leegoed = $row["leeggoed"];

  $list->setCellValue('A'.$rowcounter, $tijd);
  $list->setCellValue('B'.$rowcounter, $row['shopNaam']);


   while($red = mysqli_fetch_assoc($rez)){
        echo $red["prodNaam"] . "<br />"; 
        $list->setCellValue('C'.$rowcounter, $red["prodNaam"]."\r");
        $list->getStyle('C'.$rowcounter)->getAlignment()->setWrapText(true);
   }


  $list->setCellValue('D'.$rowcounter, $ime);
  $list->setCellValue('E'.$rowcounter, $adresa);
  $list->setCellValue('F'.$rowcounter, $gemeente);
  $list->setCellValue('G'.$rowcounter, $telNummer);
  $list->setCellValue('H'.$rowcounter, $email);
  $list->setCellValue('I'.$rowcounter, $leegoed);
  $rowcounter++;
}


$writer = new PHPExcel_Writer_Excel2007($excel);
$writer->save('files/users.xlsx');

在while循环中的$ prod_id中，我得到了产品的所有ID，但因为我在查询中使用GROUP_CONCAT（我使用它，因为我需要在我的excel文件中显示）我不知道单独获取它们，但分组。而现在我无法获得这些产品的数量。

我在数据库中的表格如下：

Order_details表（我需要的数量（ aantal ））

+---+----------+--------------------+----------+--------+
|id | order_id | product_shop_tt_id | leeggoed | aantal |
+---+----------+--------------------+----------+--------+
|180|       87 |                51  |          |    2   |
|181|       87 |                52  |          |    3   |
|182|       88 |                32  |          |    2   |
|183|       88 |                35  |          |    5   |
|184|       88 |                55  |          |    3   |
+---+----------+--------------------+----------+--------+

然后我的product_shop_tt表与order_details表和products表连接：

+--+------------+---------+-------+
|id| product_id | shop_id | price |
+--+------------+---------+-------+
|32|          1 |      20 |  25.8 |
|33|          5 |      20 |  13.6 |
|34|          4 |      18 |       |
|35|         26 |      20 |       |
|36|         27 |      18 |       |
+--+------------+---------+-------+

最后我的产品表：

+--+-------------------------+-------------------------+-----------------+---------+--------+
|id| naam                    | details                 | keywords        | type_id | active |
+--+-------------------------+-------------------------+-----------------+---------+--------+
| 1| Test promjena           | Ovdje idu detalji       | Ovo su keywords |       2 |      1 |
| 4| Test                    | Ovo je opis proizvoda:) | rijec. rijec1   |       2 |      1 |
| 5| ime_proizvoda           | detalji                 | keywords        |       2 |      1 |
|26| neko meso recimo (50gr) |                         |                 |       2 |      0 |
+--+-------------------------+-------------------------+-----------------+---------+--------+

在$ red中我没有取任何东西，因为我的$ prod_id被分组了。如何单独获取产品的所有ID，但我的$ rezOrders查询必须给出相同的结果？

我在excel文件中得到的结果如下（这是我想要的结果）：

+---------------------+-------------------------+-------------------------+------------------+-------------------+----------+----------------+
| Tijd                | Shop                    | Products                | Naam en voornaam | Adres             | Gemeente | Telefoonnummer |
+---------------------+-------------------------+-------------------------+------------------+-------------------+----------+----------------+

+---------------------+-------------------------+-------------------------+------------------+-------------------+----------+----------------+

我要做的是在每个产品旁边写下他的数量，该数量位于order_details表中。

当我更改我的第一个查询GROUB BY order_details.id然后我可以分别从每个产品的order_details获取数量值，但现在我没有在我的excel文件中得到正确的显示。我为每个产品添加了一个新行，但我想在第一张照片上得到它。现在我把它作为休耕 enter image description here

答案 0 :(得分：1)

您的prodId是一个包含"id1\rid2\rid3"的字符串。如果替换所有"\r"的智慧", "并使用SQL IN ()语句而不是=。

替换：

WHERE producten.id = " . $prod_id . "

使用：

WHERE producten.id IN (" . str_replace("\r", ", ", $prod_id) . ")
