What are the methods and steps for PHP to implement multi-specification SKU of products?

With the development of e-commerce, multi-specification (SKU) management of products has become an important issue for merchants and developers. an important issue faced. The management of multi-specification SKUs of products can help merchants clearly display the different attributes and options of the products, making it easier for consumers to choose and purchase. This article will introduce a method based on PHP to implement multi-specification SKU of products and provide corresponding code examples.

Database design

Before implementing multiple product specifications SKU, we need to design a suitable database architecture. You can create a table named "products" to store product-related information, including product ID (id), product name (name), product price (price) and other basic attributes. In addition, we can create a table named "product_variants" to store different specifications and options of the product, including specification ID (id), specification name (name), etc. At the same time, you also need to create a table named "variant_options" to store the specific options of the specification, including option ID (id), option name (name), etc.

Database relationship establishment

In order to establish the relationship between products and specifications, we can use an intermediate table to represent this relationship. You can create a table named "product_variant_options" to store the relationship between products, specifications and options. This table includes three fields: product ID (product_id), specification ID (variant_id) and option ID (option_id).

Create product page

Next, we create a product page to display the multi-specification SKU of the product. You can use HTML and CSS to design page layout, and use PHP to obtain and display product information, as well as corresponding specifications and options.

<?php
$product_id = $_GET['id']; // 获取商品ID
// 查询商品信息
$product_query = "SELECT * FROM products WHERE id = $product_id";
$product_result = mysqli_query($conn, $product_query);
$product = mysqli_fetch_assoc($product_result);
?>
<!DOCTYPE html>
<html>
<head>
    <title><?php echo $product['name']; ?></title>
    <style>
        /* 页面样式 */
    </style>
</head>
<body>
    <h1><?php echo $product['name']; ?></h1>
    <p>价格：<?php echo $product['price']; ?></p>
    <form action="add_to_cart.php" method="post">
        <?php
        // 查询商品的规格和选项
        $variant_options_query = "SELECT pv.id as variant_id, pv.name as variant_name,
                                  vo.id as option_id, vo.name as option_name
                                  FROM product_variants pv
                                  JOIN variant_options vo
                                  ON pv.id = vo.variant_id
                                  JOIN product_variant_options pvo
                                  ON pvo.variant_id = pv.id
                                  WHERE pvo.product_id = $product_id";
        $variant_options_result = mysqli_query($conn, $variant_options_query);
        $previous_variant_id = null;

        while ($row = mysqli_fetch_assoc($variant_options_result)) {
            $variant_id = $row['variant_id'];
            $variant_name = $row['variant_name'];
            $option_id = $row['option_id'];
            $option_name = $row['option_name'];

            if ($variant_id != $previous_variant_id) {
                echo "<h2>$variant_name</h2>";
            }

            echo "<input type="checkbox" name="options[]" value="$option_id"> $option_name<br>";

            $previous_variant_id = $variant_id;
        }
        ?>
        <button type="submit">添加到购物车</button>
    </form>
</body>
</html>

Processing form submission

After the user selects the corresponding specifications and options, click the "Add to Cart" button to submit the form. We need to use PHP to handle form submission and add selected specifications and option information to the shopping cart.

<?php
$selected_options = $_POST['options']; // 获取选中的规格和选项
// 处理选中的规格和选项信息，可以将其添加到购物车中

// 重定向到购物车页面
header("Location: cart.php");
exit;
?>

Through the above steps, we can implement a multi-specification SKU management system based on PHP. Merchants can easily manage product specifications and options and provide users with more choices. At the same time, the code sample also shows how to create and use a database to implement the association between specifications and options, and how to process the user's selection and add it to the shopping cart. I hope this article will be helpful in understanding and practicing the methods and steps to implement multi-specification SKUs for products.
