Redirection after finishing placing the order

Hi

I have a question about the checkout workflow.
I have website for printing office, and I'm using Hikashop (which is, by the way exellent) to configure products and online orders of printing.
Everything is doing great, and I have it almost completed (YEAH!!!)
Now, at the end of checkout proces I want to display custom joomla article with module to upload file for printing.
Instead, I'm getting thank U note at the end.

Which file (listing) should I edit to achieve this?

I'm using hikashop essential on joomla 2.5.

It seems that there is no such option in checkout workflow (and I tried them all). Or maybe I'm missing some?

I also checked forum for such issue, but couldn't find similiar threads that could help me.

Hi,

You can try to edit the view "checkout/after_end" and set a redirection to a Joomla article.
Or in the payment plugin set a return url, or edit the file "..._end.php" in the plugin folder to change the exit page.

Hi.
I'm kind a new to php. Are this the right lines?

$app =& JFactory::getApplication();
$app->enqueueMessage( JText::_('THANK_YOU_FOR_PURCHASE') );

Yes, and instead of these lines you can use:
