PHP mall development skills: Design product details pages and recommended product functions

Introduction:
With the rapid development of e-commerce, more and more companies have begun to build their own online malls. As the core component of an online mall, the design of product detail pages and recommended product functions has become particularly important. This article will introduce some PHP mall development techniques to help developers design product details pages that attract users and effective recommended product functions.

1. Design the product details page
The product details page is an important page for users to understand product details. A good product details page should clearly display the basic information, specifications, picture display, product description and user reviews of the product.

1. Use the database to store product information
   First, we need to create a product table in the database, including product ID, product name, product price, product description, product pictures and other fields. By querying the database, product information is dynamically displayed on the product details page.

<?php
// 连接数据库
$connection = mysqli_connect("localhost", "username", "password", "database");

// 查询商品信息
$query = "SELECT * FROM products WHERE id = 1";
$result = mysqli_query($connection, $query);
$product = mysqli_fetch_assoc($result);

// 展示商品信息
echo "商品名称：" . $product['name'];
echo "商品价格：" . $product['price'];
echo "商品描述：" . $product['description'];
// 等等...
?>

2. Picture display
   In the product details page, displaying product pictures can attract the user's attention. Use HTML and CSS to implement image display functions.

<div class="product-image">
    <img src="<?php echo $product['image']; ?>" alt="商品图片">
</div>

3. Specification parameter display
   Some products have different specifications and parameters. We can store the specification parameters in the database and display them on the product details page.

<?php
// 查询规格参数
$query = "SELECT * FROM spec_params WHERE product_id = 1";
$result = mysqli_query($connection, $query);
while ($param = mysqli_fetch_assoc($result)) {
    echo $param['param_name'] . "：" . $param['param_value'];
}

2. Design the recommended product function
The recommended product function can provide users with personalized recommendations and increase the possibility of users purchasing. Here are some ways to implement the recommended product feature.

1. Recommendation based on user behavior
   By analyzing the user's historical purchase records, browsing records and search records, we can recommend related products based on the user's interests.

<?php
// 获取用户ID
$user_id = $_SESSION['user_id'];

// 获取用户浏览记录
$query = "SELECT * FROM view_logs WHERE user_id = $user_id";
$result = mysqli_query($connection, $query);

// 提取浏览记录中的商品ID
$product_ids = [];
while ($log = mysqli_fetch_assoc($result)) {
    $product_ids[] = $log['product_id'];
}

// 根据浏览记录推荐相关商品
$query = "SELECT * FROM products WHERE id IN (" . implode(',', $product_ids) . ")";
$result = mysqli_query($connection, $query);
while ($product = mysqli_fetch_assoc($result)) {
    echo $product['name'];
    // 等等...
}
?>

2. Recommendation based on product similarity
   In addition to recommending products based on user behavior, we can also recommend related products based on product similarity. For example, the collaborative filtering algorithm is used to calculate the similarity between products and find other products that are highly similar to the user's favorite products for recommendation.

<?php
// 获取用户喜欢的商品ID
$user_id = $_SESSION['user_id'];
$query = "SELECT * FROM like_logs WHERE user_id = $user_id";
$result = mysqli_query($connection, $query);
$product_ids = [];
while ($log = mysqli_fetch_assoc($result)) {
    $product_ids[] = $log['product_id'];
}

// 根据商品相似度推荐相关商品
$query = "SELECT * FROM products WHERE id IN (
    SELECT product_id FROM product_similarity WHERE source_product_id IN (" . implode(',', $product_ids) . ")
)";
$result = mysqli_query($connection, $query);
while ($product = mysqli_fetch_assoc($result)) {
    echo $product['name'];
    // 等等...
}
?>

Conclusion:
Designing an attractive product details page and effective recommended product functions are crucial to a successful online mall. By rationally using the database to store product information and dynamically displaying it on the product details page, and making personalized recommendations based on user behavior and product similarity, we can improve the user experience and increase the user's likelihood of purchasing.
