Can someone help me on how to use Trigger in Codeigniter?

A trigger works on the database side. For example, you can use a trigger to move a record from table_A to table_B on update/delete (on some event). There are plenty of tutorials/ write-ups on this, please read one of them. Here is one, http://www.mysqltutorial.org/mysql-triggers.aspx
