我正在使用phpexcel，但是我通過從數據庫獲取結果而遇到問題。從數據庫中獲取結果
我有下面的代碼：
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 producten ON producten.id = product_shop_tt.product_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,

);
/*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"];

$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);

$list->setCellValue('G'.$rowcounter, $telNummer);

$rowcounter++;
}
$writer = new PHPExcel_Writer_Excel2007($excel);
$writer->save('files/users.xlsx');
在$ PROD_ID在while循環，我得到一個產品的所有的ID，而是因爲我在查詢（使用GROUP_CONCAT我使用它，因爲我需要在這樣的顯示器我的excel文件）我沒有單獨獲取它們，但分組了。現在我無法獲得這些產品的數量。是
我的數據庫中的表如下：
ORDER_DETAILS表（有數量（aantal），我需要）
+---+----------+--------------------+----------+--------+
|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 |
+---+----------+--------------------+----------+--------+
這與ORDER_DETAILS表連接的，那麼我product_shop_tt表和產品表：
+--+------------+---------+-------+
|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 | |
+--+------------+---------+-------+
而最後我的產品表：
+--+-------------------------+-------------------------+-----------------+---------+--------+
|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 |
+--+-------------------------+-------------------------+-----------------+---------+--------+
In $ red我不抓取任何東西，因爲我的$ prod_id是分組的。我如何分別獲得產品的所有id，但是我的$ rezOrders查詢必須提供相同的結果？
結果，我在我的Excel文件得到如下（這是導致我想）：
+---------------------+-------------------------+-------------------------+------------------+-------------------+----------+----------------+
| Tijd | Shop | Products | Naam en voornaam | Adres | Gemeente | Telefoonnummer |
+---------------------+-------------------------+-------------------------+------------------+-------------------+----------+----------------+
| 2015-08-15 14:11:56 | Bakkerìj Van Hecke | Test promjena | Borís Jelic | Krijgsgraat 130 | Gent | 486386069 |
| | neko meso recimo (50gr) | | | | | |
| | buffon | | | | | |
+---------------------+-------------------------+-------------------------+------------------+-------------------+----------+----------------+
| 2015-08-15 14:11:14 | Lidl | prod1 | Mesanovic Maida | Krihuisstraat 130 | Brussel | 486742185 |
| | | prod2 | | | | |
+---------------------+-------------------------+-------------------------+------------------+-------------------+----------+----------------+
我試圖做的是未來將要寫入每個產品的他數量位於order_details表中。
當我在第一次查詢GROUB BY order_details.id中更改時，我可以分別從每個產品的order_details中獲取數量值，但現在我無法在我的Excel文件中獲得正確的顯示。我爲每個產品獲得一個新的行，但我想要像第一張照片一樣。現在我將它作爲休耕地 
是否'$行[ 'PRODID']'包含正確的價值？您在SELECT語句中未選擇字段「prodID」。 –
@ mario.klump我的不好。是的是的。在代碼中，我只是沒有複製它。問題是一樣的。 – Boky
嘗試''echo出所有的SQL查詢並通過phpMyAdmin運行它們。如果他們工作，那麼問題可能在於您設置或連接變量的方式。 – Tim
