Steps to implement the product search keyword association function in PHP Developer City

With the development of Internet technology, the field of e-commerce is developing more and more rapidly. As an important function of e-commerce platforms, the product search function is crucial to improving user experience. The product search keyword association function can further enhance the user experience and provide more intelligent and convenient search results.

Below, we will introduce in detail how to search for keywords and associate functions based on the product in the PHP developer city. The implementation steps are as follows:

1. Database design and preparation
   First, you need to design A database table used to store products, including fields such as product ID, product name, product description, etc. In this table, we also need to add a field specifically used to store search keywords. At the same time, we need to prepare some commonly used search keywords, which will be used for keyword association.
2. Create input box and association list
   In the page, create an input box for users to enter keywords, and create an association list to display related search keywords. Use HTML and CSS to beautify the input box and association list, and add corresponding event listeners.
3. Request back-end data through AJAX
   Use AJAX technology in JavaScript to initiate a request to the back-end to obtain associated keyword data related to the keywords entered by the user. The path of the request should be agreed with the backend developer, and the keywords entered by the user need to be passed to the backend as request parameters.
4. Back-end data processing
   In the back-end, after receiving the keyword parameters passed by the front-end, based on this keyword, the associated associated keyword data is queried from the database. You can use the LIKE keyword of the SQL statement to perform fuzzy matching. Return the query results to the front end in JSON format.
5. Front-end data analysis and display
   After the front-end receives the association keyword data returned by the back-end, it parses the data and displays the parsed data in the association list. You can use JavaScript DOM operations to dynamically add list items.
6. Lenovo Keyword Click Event
   When the user selects an associated search keyword in the Lenovo list, the keyword needs to be filled in the input box and the search function is triggered. This can be achieved by listening to the click event of the list item.
7. Search function implementation
   When the user clicks the search button or presses the Enter key after entering the keyword, the search function needs to be triggered. This can be achieved by listening to button click events or input box enter events through JavaScript.
8. Search result display
   Queries relevant product information from the database based on the keywords entered by the user, and displays the query results to the user. You can use PHP language to perform database queries, and use HTML and CSS to display search results pages.

Through the above steps, we can easily implement the keyword association function in the PHP mall to improve the user's search experience. Of course, this is just a basic implementation step, and specific functions and styles can be expanded in more complex and rich ways to meet the needs of different malls.
