获取会话并将数据插入数据库然后删除会话

Question

我想将显示数据产品中的数据插入数据库idk它是怎么做的

此产品是从下面的其他形式显示的

否则我必须通过按钮或表格发送？ 像这样将数据添加到数据库

id 名称 数量

1 pd01 2

2 pd03 2

cart.php

if(!empty($_GET["action"])) {
switch($_GET["action"]) {
     case "save":
        if(!empty($_SESSION["cart_item"])) {
            
            foreach($_SESSION["cart_item"] as $k => $v) {
             
      <!== HERE! i want to insert when get session from button BtnSave
                 then remove session   ==>             
            }
        }
    break;
------------------------
<?php
if(isset($_SESSION["cart_item"])){
    $total_quantity = 0;
    $total_price = 0;
?>  

<?php       
    foreach ($_SESSION["cart_item"] as $item){
        $item_price = $item["quantity"]*$item["price"];
        ?>
                <tr>
                <td><img src="<?php echo $item["image"]; ?>" class="cart-item-image" /><?php echo $item["name"]; ?></td>
                <td><?php echo $item["code"]; ?></td>
                <td style="text-align:right;"><?php echo $item["quantity"]; ?></td>
                <td  style="text-align:right;"><?php echo "$ ".$item["price"]; ?></td>
                <td  style="text-align:right;"><?php echo "$ ". number_format($item_price,2); ?></td>
                <td style="text-align:center;"><a href="index.php?action=remove&code=<?php echo $item["code"]; ?>" class="btnRemoveAction"><img src="icon-delete.png" alt="Remove Item" /></a></td>
                </tr>
                <?php
                $total_quantity += $item["quantity"];
                $total_price += ($item["price"]*$item["quantity"]);
        }
        ?>
    <td colspan="5"><a id="BtnSave" href="index.php?action=save&code=<?=$item["code"];?>&=<?= $item["name"];?>">Save!</a> </td>

代码是通过“form action=add”提交的，很长idk有必要向您展示

它可以正常添加到表上

我从某处得到这段代码并向左插入数据 提前谢谢你的回答

cart.php

------
<?php
    $product_array = $db_handle->runQuery("SELECT * FROM tblproduct ORDER BY id ASC");
    if (!empty($product_array)) { 
        foreach($product_array as $key=>$value){
    ?>
    <div class="product-item">
            <form method="post" action="index.php?action=add&code=<?php echo $product_array[$key]["code"]; ?>">
            <div class="product-image"><img src="<?php echo $product_array[$key]["image"]; ?>"></div>
            <div class="product-tile-footer">
            <div class="product-title"><?php echo $product_array[$key]["name"]; ?></div>
            <div class="product-price"><?php echo "$".$product_array[$key]["price"]; ?></div>
            <div class="cart-action"><input type="text" class="product-quantity" name="quantity" value="1" size="2" /><input type="submit" value="Add to Cart" class="btnAddAction" /></div>
            </div>
            </form>
        </div>
        
            </form>
        
    <?php
        }
    }
    ?>
