How to reset 'set_value' after valid form post - El Forum - 09-27-2009

Hi all,
I've tried searching for an answer on this one, but to no avail. Hope you can help.
I have a form that repopulates itself with 'set_value' when errors were detected via 'form_validation'.
This works fine. But when the post was successful, I want to reshow the same form. Only now I want all the fields to stay blank.
Is there a way of 'resetting' the 'set_value' values?
Code:
<?= form_open('', array('name'=>'reaction', 'id'=>'reaction-form')); ?>
<input type="text" name="name" id="name-field" value="<?= set_value('name', '') ?>" />
<textarea cols="" rows="" name="reaction" id="reaction-field"><?= set_value('reaction', ''); ?></textarea>
<button type="submit" value="ok" >Verstuur</button>

You could redirect() to the same page in order to empty the $_POST data:

Thanks PistolPete
To be honest, this one the options I thought about. But decided not to go that route since I thought it would be considered somewhat of a 'hack':
-> form post -> controller (form check) -> redirect to same controller
My feeling tells me that I should be trying to find a way to handle it all in one controller call. I'm interested to hear your opinion on this.

Redirecting after successful form posts is generally a good idea, and a good, common practice. For one, it prevents double-posting. Nothing hacky about it1
