Form input fields +form_validation required but not equal to default???

Hi,

so i am using this to make some form fields

Code:

<?php echo form_label('fname').form_input('fname','fname');?>

and form_validation

Code:

$this->form_validation->set_rules('fname', 'fname', 'trim|required');

1/ Now because i already have fname as text value the validation passes, how do i fix this?
2/ How do is set already filled in values?? set_value???

regards,
