在PHP會話中存儲乘數變量並使用循環顯示全部

-1

我希望通過存儲來自ORDER頁面的訂單值並將其顯示在CART頁面上來保存產品。這裏是兩個頁面編碼。任何人都可以幫助我嗎？這是爲wordpress主題。在PHP會話中存儲乘數變量並使用循環顯示全部

訂購頁面

<?php 
session_start(); 
/* 
TEMPLATE NAME: Order Page 
*/ 


$git_product_id = $_GET['git_product_id']; 
$git_required = $_GET['git_required']; 
$git_action = $_GET['git_action']; 

if ($git_product_id != "" && $git_required != "" && $git_action != ""){    
    ?> 
     <form action="" method="POST" class="add-form"> 
      <label> 
       <?php 

        switch($git_required){ 

         case "name" : 
          // showing Name 
          echo "Account Name:"; 
         break; 

         case "url" : 
          // showing url 
          echo "Web Url:"; 
         break; 

        }; 
       ?> 
      </label> 
      <input type="text" name="git_required" value="" /> 
      <input type="hidden" name="git_product_id" value="<?php echo $git_product_id; ?>" /> 
      <input type="hidden" name="git_action" value="add" /> 
      <input type="submit" value="Add to cart" class="add-to-cart-button" /> 
     </form>

} else { 

    echo "Sorry an error took place.";

當您回顯產品詳細信息時，刪除$ product周圍的單引號 – Raad 2013-02-18 12:58:26

您需要向帖子中添加更多詳細信息。 - 什麼不工作？它顯示什麼或什麼都沒有？ - 是否顯示任何錯誤？ - 您是否使用現有的購物車組件？添加這個名字可以幫助那些有經驗的人幫助你。 – youcantseeme 2013-02-18 12:59:09

@ youcantseeme：請檢查主張。我已經共享了訂單頁面和購物車頁面的編碼。 – Nur 2013-02-18 14:06:12

你寫$_SESSION['cart']['$product']...而是你應該寫$_SESSION['cart'][$product]...沒有「輪$產品...

說明：'$product'不是$產品的價值，但只有字符串$產品：

$product = 5; 
var_dump($product);  // -> int(5) 
var_dump("$product");  // -> string(1) "5" 
var_dump('$product');  // -> string(8) "$product"
