Passing GET value show error

There must be something else going wrong with your code. A missing argument error is not a message you get with a view file, but with a controller. With a view file any missing data is displayed in the html as a php error.

is simple , the method want an argument , when the form_validation is false this is the code :

Code:

               $this->load->view('templates/header', $data);
               $this->load->view('templates/menu', $data);

               $this->load->view('documentazione/crea_documentazione_seconda', $data);


               $this->load->view('templates/footer', $data);

and the $id is not isset , but i want know if ther's an alternative way to do this....
