PHP Mall Function Tutorial: Implementing Collection and Sharing Functions

PHP Mall Function Tutorial: Implementing Collection and Sharing Functions

In modern e-commerce, collection and sharing functions have become important means to promote product sales and user participation. This tutorial will take you step by step to implement the collection and sharing functions of a PHP-based shopping mall website.

1. Implementation of collection function

1. Create database table

First, we need to create a database table for storing collection product information. You can use the following SQL statement to create a data table named "collections":

CREATE TABLE collections (

id INT AUTO_INCREMENT PRIMARY KEY,
user_id INT,
product_id INT,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP

);

2. Add collection button

In the HTML code of the product details page, add a favorite button. For example:

Collection

3. Add JavaScript code

Use JavaScript to associate the favorite button with back-end logic. For example, you can use the jQuery library to simplify things:

$(document).ready(function() {

$("#collectBtn").click(function() {
    var productId = $(this).data("productid");
    $.ajax({
        type: "POST",
        url: "collect.php",
        data: { product_id: productId },
        success: function(response) {
            if (response.status == "success") {
                alert("商品已成功收藏！");
            } else {
                alert("收藏失败，请稍后再试。");
            }
        }
    });
});

});

4. Create backend collection Processing script

On the server side, create a file named "collect.php" to handle the click event of the collection button. In this file, you can write PHP code to write collection information to the database. The sample code is as follows:

// Connect to the database
$pdo = new PDO("mysql:host=localhost;dbname=db_name", "username", "password") ;

// Get the current user ID (assuming the user is logged in)
$userId = $_SESSION["user_id"];

// Get the product ID parameter sent through the POST request
$productId = $_POST["product_id"];

// Write collection information to the database
$sql = "INSERT INTO collections (user_id, product_id) VALUES (?, ?)" ;
$stmt = $pdo->prepare($sql);
$stmt->execute([$userId, $productId]);

// Return successful response
echo json_encode(["status" => "success"]);
?>

At this point, the collection function has been implemented. After the user clicks the collection button, the collection information of the product will be written into the database.

2. Implementation of sharing function

1. Create database table

Similar to the collection function, we need to create a database for storing shared product information surface. You can use the following SQL statement to create a data table named "shares":

CREATE TABLE shares (

id INT AUTO_INCREMENT PRIMARY KEY,
user_id INT,
product_id INT,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP

);

2. Add share button

In the HTML code of the product details page, add a share button. For example:

Share

3. Add JavaScript code

Use JavaScript to associate the share button with backend logic. The sample code is as follows:

$(document).ready(function() {

$("#shareBtn").click(function() {
    var productId = $(this).data("productid");
    $.ajax({
        type: "POST",
        url: "share.php",
        data: { product_id: productId },
        success: function(response) {
            if (response.status == "success") {
                alert("商品已成功分享！");
            } else {
                alert("分享失败，请稍后再试。");
            }
        }
    });
});

});

4. Create a back-end sharing processing script

On the server side, create a file named "share.php" to handle the click event of the share button. In this file, you can write PHP code to write the sharing information to the database. The sample code is as follows:

// Connect to the database
$pdo = new PDO("mysql:host=localhost;dbname=db_name", "username", "password") ;

// Get the current user ID (assuming the user is logged in)
$userId = $_SESSION["user_id"];

// Get the product ID parameter sent through the POST request
$productId = $_POST["product_id"];

// Write sharing information to the database
$sql = "INSERT INTO shares (user_id, product_id) VALUES (?, ?)" ;
$stmt = $pdo->prepare($sql);
$stmt->execute([$userId, $productId]);

// Return successful response
echo json_encode(["status" => "success"]);
?>

At this point, the sharing function has also been implemented. After the user clicks the share button, the sharing information of the product will be written into the database.

Summary:

This tutorial takes you through the implementation of the collection and sharing functions of a PHP-based mall website. By adding collection and sharing functions, users can easily find their favorite products and share them with others. Through the flexible use of JavaScript and PHP technologies, we can customize and expand according to actual needs. I hope this tutorial will be helpful to your mall website development and user engagement!
