Question

I have an Codeigniter app (using version 2.1.0) that is writing a transaction to a mysql database. I’m fairly sure that I’ve got a foreign key constraint error occurring, but I can find no way to make CI tell me the specific error. mysql_error() comes back empty.

Can anyone tell me how to get Codeigniter to tell me the mysql error message?

Answer 1

Yes, this is the mysql_error() wrapper.

$this->db->_error_message();

And the mysql_errno wrapper is:

$this->db->_error_number();
