Answer 2

param() obtains the entire object, and there are many things in it that are not fields in your data table. You must first print out the data in $data and take a closer look at your code, such as saving the user name. The $data['username'] you submitted is not what you want. You have to find the parameters you need first and then save them.

I don’t understand what your problem is. Isn’t the code for inserting into the database already written in your program?
