Unknown column 'email' in 'field list'

[eluser]TheFuzzy0ne[/eluser]
$this->email is the email library. It's accessible from both your model and from your controller. When CodeIgniter loads a model, the model imports methods and properties from the CodeIgniter Super Object. If you don't want that behaviour, you can override it.

./system/application/libraries/MY_Model.php

Code:

class MY_Model extends CI_Model {

    function _assign_libraries() { }

}
// End of File: MY_Model.php
// Location: ./system/application/libraries/MY_Model.php

The above code is untested, but should suppress the behaviour you mentioned.
