In today’s e-commerce era, gift malls have become an important platform for people to purchase gifts. To implement an online gift mall, PHP is a very good technology choice. In this article, we will explore how to implement an online gift mall using PHP.

1. Target functions

Before starting coding, we need to determine the target functions of the mall, that is, what operations users should be able to perform. Specifically, it should have the following functions:

1. User registration and login: Allow users to create an account in the mall, so that they can log in and browse products, create orders, and view order history.

2. Product browsing and search: Allow users to search or browse products in the mall. Users can search for products based on keywords, categories or price.

3. Shopping Cart: When users browse items in the mall, they should be allowed to add items to the shopping cart for purchase at checkout.

4. Checkout: At checkout, users should be able to choose which payment method to use and enter payment information.

5. Order tracking: The mall should save user order history and allow users to view order status and other details.

2. Database design

After determining the target function of the mall, we need to design the database. The following are the basic entities we will use:

1. User (User): Contains fields such as username, password, email address, and payment information.

2. Product: Contains fields such as product name, description, price, category, and quantity in stock.

3. Order: Contains fields such as order total, user ID and order status.

4. Order details (Order_Detail): Contains fields such as product ID, order ID and purchase quantity.

When creating a table, we need to consider the following matters:

1. Encrypt the user password and store it to ensure security.

2. Use foreign key constraints to ensure that only existing products and orders can be added in the order details table. Deleting products or orders will also delete the corresponding order details records.

3. Store the inventory quantity in the product table instead of the order details to ensure that the product quantity is updated correctly.

3. PHP Implementation

After completing the database design, we need to connect it to the PHP project so that it can perform the required operations.

1. User registration and login
To create an account for a user, we need a user registration page that will save the new user's information in the database. To implement user login, we can use an HTML login page to authenticate the user and then redirect them to the homepage of choice.

2. Product browsing and search
In order to apply search on products, we can use form submission. After the user fills out the form, the page will display products that match the search criteria.

3. Shopping cart
To implement the shopping cart, we can save it in the session. When the user adds an item, it is added to the shopping cart and the number of products in the cart is displayed on the page. At checkout, remove items from your cart and create a new order.

4. Checkout
At checkout, we need a checkout page to allow the user to select a payment method and submit payment information. After completing the payment, the mall should generate a new order and update the inventory quantity.

5. Order Tracking
Users can view their order history. Users can access their order details page, which includes information such as items purchased, order number, order amount, and order status.

4. Security

Security is the key to any e-commerce application. Here are important steps to implement security measures:

1. Use appropriate form validation and input filtering to prevent SQL injection attacks, XSS and CSRF attacks, etc.

2. Delete expired data from the session to protect the session from attacks such as CSRF and session hijacking.

3. Use salted hashes to ensure security when storing passwords.

4. Use HTTPS to protect the transmission of sensitive data.

5. Keep error logs to help detect attacks.

In conclusion, if we follow the above steps, implementing an online gift mall using PHP and ensuring security will be a relatively easy task. Whether you are new to e-commerce or an experienced web developer, I hope this article will be helpful to you.
