Yukarıdaki cart.php güncellenmiş kod ve sorgu. Eğer sorgu altında fark ederseniz, bir süre döngü vardır. Şu anda ise döngü mükemmel dkb tablo için sayfa1.php gelen ürün olan kurulur. Bu döngü bu, kaydetmek tekrar ekran ve yönetmek ecah madde Adet Adet, resim, isim, fiyat ve seçenekleri kaldırın, bunları görüntüleyebilir ve onlara kullanıcının seçtiği gibi birçok ürün tekrar edecek bir şekilde ayarlanır. Peki kurmak alanları ve tasarım arabası görüntülenen bilgiler tablolar DKB ve dbl yukarı çekin alır sayfa2.php gelen kalemlerinden oldukça işe değil. Sorun şu anda Sepete sayfa2.php gelirken şöyle dbl tabloda tasarım, çünkü aynı madde adı üç kez tekrarlar olmasıdır.
INSERT INTO `dbl` (`id`, `price`, `variety`, `description`) VALUES
(1, 20.30, 'Small Tray', 'Serves 6 to 8 people' ),
(1, 25.90, 'Medium Tray', 'Serves 12 to 15 people'),
(1, 30.90, 'Large Tray', 'Serves 18 to 21 people'),
(136, 0.00, 'Small Tray', '', 'small'),
(136, 0.00, 'Medium Tray', '' ),
(136, 0.00, 'Large Tray', ''),

$result = mysql_query("SELECT * FROM .... LEFT OUTER JOIN .... WHERE") // This is the query we have discussed in this forum.
while($row = mysql_fetch_array($result))

foreach ($row['dkb_id'] as $variety) {
echo"<div>".$variety['variety']. $variety['price3'] . "</div>";
// the vriety and price3 field will display three times as in table dbl has three prices and three variety. It is correct to use a foreach loop for in this case?}
echo"<div>remove</div>";
// end of foreach loop inside the else statement
}// end of if else statement
}// end of while loop
?>
Yani son görüntü ve arama için illüstrasyon ve bir nihai ürün olarak mevcut Yani istenen bakalım, aşağıdaki gibidir.
while($row = mysql_fetch_array($result))
{
if (table cdkb) {
[1]qyt image name price remove
1 --- marina $18.90 remove?
}end of if statement
Else table dkb {
1]qyt Image Name Price Remove
1 --- marina Small Tray $18.90 remove?
Medium Tray $30.24
Large Tray $35.90
} // end of else statement
}//end of while loop
Bana bu konuda nihai elini ver.
