Forms and Databases (Best Practice)

[eluser]jpeffer[/eluser]
I generally use the field names defined within my form validator definition to extract only those fields from the POST. Something like the following:

Code:

// Remove keys from the registration_data array that were not validated
$registration_data = array_intersect_key($registration_data, $this->CI->form_validation->_field_data);

$registration_data is set as the method parameter in my authentication lib. All I then have to do from the controller is simply pass the $_POST array.... done
