Form Helper - set_value()

I have a form setup using the CI Form Helper, mainly the set_value() feature.

The same view file with the form is used for creating new "pages", as well as editing pages, ill use the page_title as an example input from my form.

PHP Code:

<input type="text" id="page_title" name="page_title" value="<?php echo set_value('page_title', @$settings->title); ?>" /> 


So initially, that works fine..

• If editing a page, then $settings->title will be set and the value will be the page title
  
• If creating a new page, it will be empty
  
• If creating a new page, and the validation fails, the value will be the previously populated value
  

I also have it setup so if you select the Create another page checkbox, then it will load the form again, allowing you to re-populate the fields and create another page.

The question I have is, when you populate the values in the field, hit submit, and the page is successfully created, how can I have the form loaded, with the values then being empty?
