在MySQL表中操作单个产品

Question

我正在开发一个小订单购物车，目前我已经实施了MySQL来显示数据库中的产品。我希望这些产品能够拥有自己的图像，并将其组织成3个独立的桌子，用于开胃菜，主菜和甜点。

目前，我有一个包含所有商品的表格，我不确定如何在所选商品旁边添加图片。

这里显示：

这是我的代码：

<?php

session_start();

$page = 'index.php';

mysql_connect('localhost','root','') or die(mysql_error());
mysql_select_db('cart') or die(mysql_error());

if (isset($_GET['add'])) {
    $quantity = mysql_query('SELECT id, quantity FROM products WHERE id='.mysql_real_escape_string((int)$_GET['add']));
    while ($quantity_row = mysql_fetch_assoc($quantity)) {
        if ($quantity_row['quantity']!=$_SESSION['cart_'.(int)$_GET['add']]) {
            $_SESSION['cart_' . (int)$_GET['add']] +='1';
            header('Location: ' . $page);

    }
}
header('Location: ' . $page);

}

if (isset($_GET['remove'])) {
    $_SESSION['cart_'.(int)$_GET['remove']]--;
    header ('Location: ' . $page);

}

if (isset($_GET['delete'])) {
    $_SESSION['cart_' . (int)$_GET['delete']]='0';
    header ('Location: ' . $page);
}



function products() {
    $get = mysql_query('SELECT id, name, description, price FROM products WHERE quantity > 0 ORDER BY id ASC');
    if (mysql_num_rows($get) == 0) {
        echo "There are no products to display.";
    }
    else {
    echo "<center>\n";
    echo "  <table border=2 width=40% cellspacing=5 cellpadding=10 bgcolor=cyan cols=2>\n";
    echo "      <tr>\n";
    echo "      <th>View</th>\n";
    echo "      <th>Dish</th>\n";
    echo "      <th>Description</th>\n";
    echo "      <th>Item Price</th>\n";
    echo "      </tr>\n";
    while ($get_row = mysql_fetch_assoc($get)) {

    ?>
    <tr>
        <td> <a href="ice.png"</a> </td>
        <td> <?echo '<p>'.$get_row['name']?> </td>
        <td> <?echo $get_row['description']?> </td>
        <td> <?echo '&pound'.number_format($get_row['price'],2).'<br><br> <a href="cart.php?add='.$get_row['id'].'">Add</a></p>';?> </td>
    </tr>
    <?
    } 
    echo "</table>\n";
    echo "</center>\n";
}
}

您可以向具有产品类型的表添加字段。 因此，您将能够使用条件执行3个单独的查询。 例如"SELECT id, name, description, price FROM products WHERE quantity > 0 AND type LIKE 'desert' ORDER BY id ASC"等等
