Redirect with Errors

[darktangent]

In the ordercontroller override i need to redirect to a page with errors. But when a redirect the errors are lost.

 

Like when i am at step 1 of the controller i need to go back to the cart page. But if i redirect using

 

$this->errors[] = 'There is an erro';
Tools::redirect('/index.php?controller=order');

 

The errors get lost. I think prestashop generates a new http request in the redirect. what should i do so that i can step back to step no. 0 and keep the errors?

 

Thanks
