Repopulating HTML select after failed form validation

[eluser]frist44[/eluser]
I have a helper function that I don't have access to right now, but it takes a default value like the above. You could just send it to the post value as selected.

echo form_dropdown('fieldname', array( 1 => 'Value 1', 2 => 'Value 2'), $this->input->post('fieldname'));
