Question

我在创建购物车时遇到了麻烦。如何进行输出，以便当我单击产品表上的“添加购物车”按钮时，它将显示在购物车上？

//Product List
<?php 

    $query = "SELECT * FROM products";
    $exec = mysqli_query($connection, $query);

    while ($row = mysqli_fetch_array($exec)) {
      $product_id = $row['product_id'];
      $product_name = $row['product_name'];
      $product_quantity = $row['quantity'];
      $product_price = $row['sell_price'];


   ?>
      <tr>
          <td class="text-center"><?php echo $product_id; ?></td>
          <td><?php echo $product_name; ?></td>
          <td><?php echo $product_price; ?></td>
          <td><?php echo $product_quantity; ?></td>
          <td class="text-center">
            <div class="btn-group">
              <a href="add_sales.php?action=add&product_id=<?php echo $product_id; ?>"  class="btn btn-xs btn-info" data-toggle="tooltip" title="Select">
                <span class="fa fa-shopping-cart"></span>
              </a>
            </div>
          </td>
      </tr>
      <?php } ?>

    if (isset($_GET['product_id'])) {

      $prod_id = $_GET['product_id'];

      $selectProd = "SELECT * FROM products WHERE product_id = $prod_id";
      $execProd = mysqli_query($connection, $selectProd);

      while ($row = mysqli_fetch_array($execProd)) {

        $prod_name = $row['product_name'];
        $prod_price = $row['sell_price'];
        $quantity = $row['quantity'];

Answer 1

当您提交表单，URL查询参数（如果表单具有GET方法）或请求正文参数（POST方法）时，您的input元素都没有name属性（我认为））无法获得，你无法抓住＆＃34;提交订单的人的行为。如果您添加它们并处理表单提交（例如if isset($_POST['order'])，您可以INSERT将订单导入数据库并从数据库表中呈现购物车。同时查看{ {3}}以避免SQL注入。
