Sending user back to referrer

[eluser]rdjs[/eluser]
There were a couple of small typos in the code above. Nothing major but thought I would clarify to save confusion. Also current_url() was added in version 1.7 and would work nicely here:

To set the referrer in the flashdata:

Code:

$this->session->set_flashdata('referrer', current_url());

And to retrieve the referrer data

Code:

redirect($this->session->flashdata('referrer'), 'refresh');
