in relational database design the typical practice would be to include in payments table schema the foreign key of the users table.  just a thought.


but i'll answer the question you asked. in the crud for one table you would use callbacks to synchronize the corresponding attribute in the other table.


the documentation covers how to set up callbacks.


in the callback you would use codeigniter's active record classes to do the work.


see the codeigniter documentation if you are not familiar with those classes.
