Storing a request URL

[eluser]WanWizard[/eluser]
Ah, you're right.

I use a modified Session library that only writes the session once, at the end. I sometimes get confused between my code and standard CI, sorry.

You could do

Code:

class MY_Session extend Session
{
    function MY_Session()
    {
        parent::Session();
    }

    function sess_read()
    {
        $result = parent::sess_read();

        if ( $result )
        {
            if ( isset($this->userdata['current_url']) )
            {
                // the previous current_url is now the referer url
                $this->userdata['referer'] = $this->userdata['current_url'];
            }
            // store the current_url
            $this->userdata['current_url'] = current_url();   // assumes you have the url helper loaded
        }
        return $result;
    }
}

This only means that the first page request after a new session record has been created, you don't have a referer. For all subsequent requests, the previous url is now the referer.
