$_GET is disabled by default by CI.

Just use get rid of the query string and use slash notation:

Code:
&lt;?=anchor('main/edit/'.$row->id, 'Edit data');?&gt;

Grab the data in your controller by using $this->uri->segment(3)

The id value is also passed to your edit function automatically by CI, you dont need to worry about the uri->segment, unless you're using some obscure route.

Code:
function edit( $id )    //$id = value from uri->segment passed by CI

{

     //edit stuff goes here...

}
