Abstract: This article will introduce how to use the product specification pop-up window selection function in PHP Developer City. First, we need to create a product specification table, and then implement the pop-up window selection function through AJAX and JavaScript. Finally, we need to process the data related to the specification selection in the code behind to achieve complete functionality. This article describes these steps in detail.

1. Create a product specification table
Create a product specification table in the database, including specification ID, specification name and options. For example, the table name could be "specification" and the fields could include "spec_id", "spec_name", and "options".

2. Use AJAX and JavaScript to implement the pop-up window selection function

1. In the product details page, create a pop-up window button and add a click event.
2. After clicking the button, use AJAX to obtain all product specification information from the background, and dynamically generate a specification selection pop-up window.
3. In the specification selection pop-up window, the selection function of radio buttons or check boxes is implemented through JavaScript, and the optional options are dynamically updated according to the user's selection.
4. After the user selects the specification, click the OK button to transfer the selected specification information to the background processing.

3. Background code processing specification selection data

1. After the background receives the specification data selected by the user, it first parses it into an array.
2. Query the database and obtain the corresponding product information based on the specification ID and specification options in the array.
3. Return product information to the front end and update product pictures, prices and other related information.

4. Improve details

1. You can add real-time updates of price, inventory and other information when selecting specifications in the pop-up window.
2. You can use CSS styles to beautify the pop-up window selection interface to make it more beautiful and easier to use.
3. You can add front-end validation to ensure that users select the correct specifications.
