The second-hand recycling website developed in PHP realizes the function of viewing historical orders for users

With the growth of the second-hand recycling market and the increase in user transaction volume, a fully functional second-hand recycling website has become more and more important. In order to improve the user experience, we can increase the usability and convenience of the website by implementing the user's historical order viewing function. This article will introduce how to use PHP development to implement this function and provide corresponding code examples.

1. Design database table structure

First, we need to design the database table structure to store information related to user orders. Suppose we need to store information such as order number (order_id), user ID (user_id), order status (status), and order amount (amount). We can design a table named orders.

The structure of the orders table is as follows:

CREATE TABLE orders ( order_id INT PRIMARY KEY AUTO_INCREMENT, user_id INT, status VARCHAR(20), amount DECIMAL(10,2) );

2. Create order page

After the user generates an order on the second-hand recycling website, we need to save the order information into the database. On the same page where the order is generated, we can add a "View Historical Orders" button to jump to the historical order page.

Add the following HTML code on the order generation page:

查看历史订单

3. Develop the historical order page

On the historical order page, we need to extract data from the database Get all the historical orders of this user and display them.

First, create a file namedhistory_orders.phpand add the following PHP code:

 0) { echo ""; echo ""; while ($row = mysqli_fetch_assoc($result)) { echo ""; } echo "
订单编号
订单状态
订单金额
".$row['order_id']."
".$row['status']."
".$row['amount']."
"; } else { echo "没有历史订单."; } // 关闭数据库连接 mysqli_close($conn); ?>

4. Test the function

After completing the above code, place thehistory_orders.phpfile in the same directory as other pages, and ensure the correctness of the database connection information.

Now, on the second-hand recycling website, when users click the "View Historical Orders" button, they will be redirected to the historical order page and display all their historical order information. If there is no historical order, the corresponding prompt message will be displayed.

By implementing the user's historical order viewing function, we can improve the user experience of the second-hand recycling website and increase users' trust and convenience in the website. The above example code can be used as a starting point for developing this feature, which you can modify and extend according to your specific needs. Hope this article helps you!
