How to use PHP to develop the dine-in ordering function of the food ordering system?

The ordering system is a system widely used in fast food restaurants, restaurants and other catering establishments. It can improve efficiency, reduce missed orders, facilitate customers, and improve the image of the restaurant. PHP is a widely used server-side scripting language. Using PHP to develop a food ordering system can improve the stability, scalability and security of the system. This article introduces how to use PHP to develop the dine-in ordering function of the food ordering system.

1. Overview

Dine-in ordering means that when a customer dines in a restaurant, after ordering a dish, the waiter will record it and pass the dish information to the chef. An ordering method in which the customer's order generates dishes and delivers the dishes to the customer's table. The main issues that need to be considered when developing a dine-in ordering system include front-end display, dish structure, order data process and payment.

2. Front-end display

The front-end display of the dine-in ordering system is mainly divided into two parts: the ordering menu and the shopping cart. The ordering menu needs to be classified according to dish categories, and labels are set for each category to facilitate customers to find and select dishes. Each dish can display the dish name, picture, price, taste and other information. Customers can set the number of dishes by clicking the " " and "-" buttons. Generally speaking, the shopping cart needs to display the list, quantity and subtotal price of the selected dishes, and also supports operations such as modifying the quantity and deleting dishes.

3. Dish structure

The dish structure mainly refers to the data structure of the dishes and the classification method of the dishes. The data structure of a dish generally includes dish ID, name, picture, price, taste, description and other information, which will be stored in the database. The classification of dishes is generally divided into large categories and small categories. The large categories can be cuisines, ingredients, functions, etc., and the small categories can be hot dishes, cold dishes, soups, etc. It is recommended to abstract the dish structure and classification method into a data model to facilitate subsequent expansion and maintenance.

4. Order data process

The order data process mainly includes the steps of cashier placing orders, kitchen preparation, waiters delivering meals, etc. In the ordering process, you can query the dish information and generate an order by connecting to the database. After the order is generated, the order-related information is stored in the database, including order ID, order time, payment amount, table number and other information. The production process needs to query the dish information from the database according to the order information and make the dishes, and deliver the prepared dishes to the corresponding tables. The food delivery process needs to match the customer's order information with the kitchen production information to ensure that the dishes delivered to the table are consistent with the customer's order.

5. Payment

The payment link is one of the most important links in the dine-in ordering system, and the security and convenience of the payment process need to be ensured. Payment methods generally include cash payment, POS machine payment, WeChat/Alipay payment, etc. WeChat/Alipay payment requires the use of a third-party payment platform. The payment link needs to record information such as payment amount, payment status, payment time, etc., and at the same time, it is necessary to ensure the consistency of data interacted with the front end.

6. Summary

The development of dine-in ordering system needs to consider front-end display, dish structure, order data process and payment, among which payment is one of the most important links. System development can be carried out with the help of PHP and related frameworks and components. The dine-in ordering system can improve the efficiency of customer ordering, reduce the workload of waiters, reduce the rate of missed orders, and increase the image of the restaurant.
