PHP購物車陣列

因此，我設置了我的購物車，以使用GET功能接收有關添加的每個項目的特定信息。但是，在讀取數據庫的實現中，如果添加另一個項目，這些值將會變得相同。如果我添加椅子1，然後再次椅子1，它增加了椅子1的總數，說有2椅子1的。但是，如果我再添加椅子2，則會有一個新的條目，但具有所有椅子的價值。PHP購物車陣列

陣列輸出

Array ([0] => Array ([item_id] => 2 [quantity] => 1) [1] => Array ([item_id] => 4 [quantity] => 7))

採購項目區

數據庫：

<?php 
include_once('config/database.php'); 
include_once('object/chair.php'); 
$database = new Database(); 
$conn = $database->getConnection(); 
$chair = new Chair($conn); 
$chair->id = $_GET['detailsid']; 
$stmt = $chair->readDetails(); 
while($row = $stmt->fetch(PDO::FETCH_ASSOC)){ 
?>

添加到購物車：

<div class="addtocart"> 
       <!--<div class="button"> 
       Add to cart 

       </div>--> 
       <div class="button"> 
       <form id="form1" name="form1" method="post" action="cart.php?detailsid=<?php echo $row['ID'];?>"> 
      <input type="hidden" name="pid" id="pid" value="<?php echo $row['ID'];?>"/> 
      <input type="submit" name="button" id="button" value="Add to Shooping Cart"/>   

        </form>

車溫控功能：

error_reporting(E_ALL); 
ini_set('display_errrors', '1'); 
include_once 'includes/db_conx.php';

     $_SESSION["cart_array"] = array(1 => array("item_id" => $pid, "quantity" => 1));

顯示處理將項目添加到'$ _SESSION ['cart_arrray']' – Fabricator

的代碼請顯示$ _SESSION [「cart_array」]的代碼 - 它可能會在下面創建一個新項目而不是合併數量，因爲數組鍵是diff – rubberchicken

好的沒問題 –

更新：

一個可能的修復可能是細節ID添加到會話陣列像這樣：

if (!isset($_SESSION["cart_array"]) || count($_SESSION["cart_array"]) < 1) 
{ 
    $_SESSION["cart_array"] = array(1 => array("item_id" => $pid, "quantity" => 1, "details_id" => $_GET['detailsid'])); 
} 
else 
{ 
    foreach ($_SESSION["cart_array"] as $each_item) 
    { 
     $i++; 
     while (list($key, $value) = each($each_item)) 
     { 
      if ($key == "item_id" && $value == $pid) 
      { 
       array_splice($_SESSION["cart_array"], $i - 1, 1, array(array("item_id" => $pid, "quantity" => $each_item['quantity'] + 1, "details_id" => $_GET['detailsid']))); 
       $wasFound = true; 
      } 
     } 
    } 
    if ($wasFound == false) 
    { 
     array_push($_SESSION["cart_array"], array("item_id" => $pid, "quantity" => 1, "details_id" => $_GET['detailsid'])); 
    } 
}

然後顯示購物車使用時該值代替$_GET一個：

$chair  = new Chair($conn); 
$chair->id = $each_item['details_id']; 
$stmt  = $chair->readDetails();

您正在使用提取的$_GET['detailsid']椅子的細節 - 這將永遠是每個迴路編號相同：

$chair  = new Chair($conn); 
$chair->id = $_GET['detailsid']; 
$stmt  = $chair->readDetails();

如果這是$item_id代替你獲取正確的椅子的細節？

是的，我有點想了很多，但我不知道如何通過除GET以外的變種。該ID是sql文件中每個項目的唯一標識符。雖然$ item_id僅適用於購物車中的每件商品，因此您可以刪除每件商品。當「添加到購物車」按鈕被擊中時，ID被作爲正在發送給detailid。 –

您能否將詳細信息與其他詳細信息一起添加到購物車陣列中？'array_push（$ _ SESSION [「cart_array」]，array（「item_id」=> $ pid，「quantity」=> 1，「detailsid」=> 99））;' –
