How to implement the promotional activity management function of PHP development ordering system

With the rapid development of the Internet and the gradual increase in people's demand for convenient and fast consumption methods, Many restaurants have begun to choose to adopt ordering systems to improve their service quality and competitiveness. In the ordering system, the promotion management function is a very important part, which can help restaurants achieve marketing goals and attract more customers. This article will introduce how to implement the promotional activity management function of the food ordering system developed in PHP.

1. Determine the needs
Before starting development, you first need to clarify the specific needs for promotional activity management. Generally speaking, the promotional activity management function mainly includes the following aspects:

1. Creation of promotional activities: Administrators can create various promotional activities as needed, including different types of activities such as full discounts and discounts. When creating, you need to fill in the name of the promotion, start and end time, participation conditions, discount methods and other information.

2. Display of promotional activities: The current effective promotions need to be displayed in the front desk ordering system to facilitate customers to understand and participate in the activities.

3. Participation in promotional activities: During the ordering process, customers can actively choose to participate in corresponding promotional activities and enjoy corresponding discounts.

4. Management of promotional activities: Administrators need to manage the created promotional activities, including editing, deleting and other operations, as well as checking the participation status of promotional activities.

2. Database design
Before starting to develop the promotion function, it is necessary to design the database and determine the corresponding data table structure. Generally speaking, you need to create the following tables:

1. Promotional activity table: record the basic information of promotional activities, including activity name, start and end time, participation conditions, etc.

2. Dishes list: Record information about various dishes, including dish names, prices, etc.

3. Promotional activity associated dish table: used to record the dish information included in each promotional activity.

4. Promotional activity participation record table: used to record each customer's participation in promotional activities, including customer ID, promotional activity ID, etc.

3. Functional implementation
After the database design is completed, you can start writing PHP code to realize the promotion management function. The specific steps are as follows:

1. Create a promotion: The administrator logs in to the backend system, enters the promotion management page, clicks the New Promotion button, fills in the relevant information of the promotion, and saves it to the database.

2. Display promotion activities: On the home page or menu page of the front desk ordering system, query the effective promotion activities in the database based on the current time and the start and end time of the promotion activities, and display them.

3. Participate in promotional activities: During the ordering process, customers can choose to participate in corresponding promotional activities. When a customer chooses to participate in a promotional activity, the corresponding participation record is saved in the promotional activity participation record table.

4. Manage promotional activities: Administrators can edit, delete and other operations on created promotional activities. In the backend system, query the promotional activity information in the database and provide corresponding management functions.

4. Security considerations
During the development process, attention needs to be paid to considering the security of the promotional activity management function to avoid some potential security risks. Specific suggestions are as follows:

1. Data verification: When users enter data, perform legality verification to prevent malicious input or SQL injection attacks.

2. Permission management: For the promotion management function, permissions should be controlled. Only administrators have the right to create, edit and delete promotions.

3. Data encryption: Sensitive information, such as customers’ personal information, etc., should be encrypted to ensure data security.

Summary:
Through the design of MySQL database and the writing of PHP code, the promotion management function of the ordering system can be realized. Combining the creation, display, participation and management functions of promotional activities can effectively improve the restaurant's service quality and customer satisfaction. At the same time, security considerations should be paid attention to during the development process to improve the security and stability of the system and provide users with a better experience.
