Form submitted
No entry in the database
The image attached describes the problem that I am facing.
I can’t find any problem in the code stated below. Is there any problem with the SQL connection? Kindly state what should I do to solve this problem. I have sent this to my friends as well and they also can’t connect it to the database.

Here are some tips to debug your application:
(1) Open a terminal and manually run database connection part and fire a query using cursor.execute() like select and check whether it runs:
(2) Print query in console in every condition part like,
in if – elif condition every part (you can use logging instead of print as well)
After getting whole query you can manually fire it in python cursor.execute() and check what happens or you can directly fire in mysql query runner (PHPMyAdmin).
This way you will also get whether your function receives submitted data or not.
If you are using pycharm of vscode you should definitely use debugger and breakpoints to solve this issue.
Make sure you have installed
pip install mysql-connector-pythonand not
pip install mysqlbecause the former does not have connector module try to make the connection first then go about debugging further.
