Relationship between two tables?

Question

PHP

There are users and settings tables.
The users table has an id column with auto-increment
How to make it so that when adding a record to the users table, a record with the same id is created in the settigns table at the same time?
Previously, I used the fact that creating a record in one of the tables, I recognized the last_insert_id, and then created a record in another table substituting this id. But did I do it right? How to implement it more correctly?

Answer 1

the trigger on the users table on insert will not approach?

Answer 2

What is the purpose of the record? Well, when you receive a request to save the settings, then write it down (an upsert-analogue in mysql, like on duplicate key), and substitute the defaults.
