How to use PHP Developer City to realize the product classification display function on the homepage

With the rapid development of e-commerce, more and more merchants choose to open their own online malls online. For mall developers, a mall system with complete functions and easy operation is very important. Among them, the product classification display function on the homepage is an important part of the mall system.

This article will introduce how to use the homepage product classification display function in the PHP developer city system. The following are the specific implementation steps:

1. Design the database table structure
In order to realize the product classification display function, you first need to design the database table structure. Generally, three tables can be designed: product classification table, product table and association table. The product classification table stores the classification information of the products, including category ID, category name, etc.; the product table stores the detailed information of each product, including the product ID, product name, product price, etc.; the association table is used to record the relationship between the product and the product category. Association relationships generally include product IDs and category IDs.

2. Develop back-end management function
In the mall system, a back-end management function is needed to facilitate merchants to manage products and product classifications. You can use PHP to develop a backend management system, including two modules: product classification management and product management. In the commodity classification management module, the function of adding, deleting, modifying and checking the commodity classification can be realized; in the commodity management module, the function of adding, deleting, modifying and checking the commodities can be realized.

3. Develop the homepage category display function
On the homepage of the mall, each product category and the products under it need to be displayed. You can use PHP to develop a public function through which product classification and product information can be obtained and displayed on the homepage. The specific implementation steps are as follows:

1. Query the product classification table, obtain product classification information, and display it on the classification column on the homepage;
2. Query the association table to obtain the corresponding information for each category Product ID;
3. Query the product table, obtain product details, and display them under the corresponding category on the homepage.

4. Implement the click-to-jump function of product classification
In the product classification column on the homepage, users can click on each category to enter the product list page under that category. You can pass the category ID parameter through the URL, and then query the product table based on the category ID on the product list page to obtain all product information under the category and display it on the page.

The above are the basic steps to implement the product classification display function on the homepage in the PHP developer city system. Of course, the specific implementation method still needs to be adjusted and improved according to specific needs. Hope this helps developers!
