echo '<td width="50%" valign="top"><strong>' . $row['name'] .

'<br><a href="added.php?id="' . $row['P_id'] . '">Add to Cart</a></td>';

}
有问题的元素是
$row['P_id']
P_id 的背景信息：
- 它是 products 表的主键
- 我什至无法呼应它的价值？

按照要求 ：）
$query = "SELECT * FROM products WHERE prodGroup='$prodGroups[0]'"; // GET PRODUCTS FROM FIRST PRODUCT GROUP
$result = mysql_query($query);
编辑
$query = "CREATE TABLE products (
P_id INT AUTO_INCREMENT NOT NULL KEY,
name VARCHAR(128) NOT NULL,
price DECIMAL(5,2) UNSIGNED NOT NULL,
descr TEXT,
imgName VARCHAR(50),
stock INT UNSIGNED NOT NULL DEFAULT '0',
prodGroup VARCHAR(128) NOT NULL
)";
