How do populate AND re-populate a form?

[eluser]RS71[/eluser]
Have you looked at the User guide?

Havent tried but it could be something like this:

Code:

<?php echo form_dropdown($birthday_day_field, $birthday_day_options, set_value($birthday_day_field, (isset($databasevalue->fetch)) ? $databasevalue->fetch : ''), $birthday_day_params); ?>

(the set_value part and its second param)
