How to get previous page url in codeigniter

Question

I need privously visited page url in a variable and to find it inside a controller. is there any way to find it?please help me.By using following code redirect($this->agent->referrer());

i can redirected to the previous page .but I need this inside a variable to check.

Solution 1

try this:

$this->load->library('user_agent');
if ($this->agent->is_referral())
{
    $refer =  $this->agent->referrer();
}

In this way you load user_agent library, check if there is a referral url and then store It into a variable to use It after

Solution 2

It may be helpful

$url= $_SERVER['HTTP_REFERER'];

Have you simply tried: $someVariable = $this->agent->referrer(); ?
