对于一个学校项目,我试图用MySQL只用MySQL创建一个购物车.为此,我有一个名为index.php的目录.这是一个包含产品的表格,每个产品后面都有一个按钮,可以将商品添加到购物车中.

唯一的问题是我无法使链接正常工作.

    <?php
    session_start();
    include 'connect.php';
    $qry = "select * from products";
    $result = mysqli_query($connect, $qry);

    echo "<table class='catalogue'>";
    echo "<tr><th>ID</th><th>Code</th><th>Name</th><th>Description</th><th>Image</th></th><th>Price</th><th>Buy</th></tr>";

    while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {

        echo "<tr><td>";
        echo $row['id'];
        echo "</td><td>";
        echo $row['product_code'];
        echo "</td><td>";
        echo $row['product_name'];
        echo "</td><td>";
        echo $row['product_desc'];
        echo "</td><td>";
        echo $row['product_img_name'];
        echo "</td><td>";
        echo $row['price'];
        echo "</td><td>";
        echo "<input type='submit' value='Add' href='cart.php?id=['id']'/>";
        echo "</td></tr>";
    }

    echo "</table>";
    ?>

cart.php看起来像这样.

    <?php
session_start();
require 'connect.php';
require 'item.php';
$result = mysqli_query($connect, 'select * from products where id='.$_GET['id']); …
