Hello teacher, I wrote the code according to your course. The front-end data cannot be submitted to the database, and there are no pop-up prompts. Please correct me.

Answer 1

Your code is too messy, and there is no TP version you downloaded. You can package the entire project and send it to me.

The current version of thinkphp is already 6. You can learn version 6.

According to your question, if the PHP operation is not completed and an error is reported, there will definitely be no pop-up box in the JS code.

Check the php code first to see if there are any errors. F12 of the browser can be viewed.
