Answer 1

View:

<form action="<?=site_url('controller_name/function_name);?>" method="get">
    <input type="text" name="temp">
    <input type="submit"/>
</form>

Controller

class controller_name extends CI_Controller{

   function function_name(){
      echo $this->input->get('temp');
   }

}

Answer 2

parse_str($_SERVER['QUERY_STRING'],$_GET);

ONLY worked for me after I added the following line to applications/config/config.php:

$config['uri_protocol'] = "PATH_INFO";
