Validation question

[eluser]chobo[/eluser]
I was doing some validation with the validation class and I was just wondering where do the variables that you are testing get stored? Currently, I validate the variables and then retrieve them from the post array like this:

Code:

$this->input->post('somefield', true);

Does retrieving the variables using CI's input->post class get the validated variables, or unfiltered ones directly from the form?

Thanks!
