Answer 1

post the code for model class and, in your model, change this

$this->db->where('username,$username');

to

$this->db->where('username',$username);

or

$this->db->where("username,$username");// single quote to double quote

in function signupchk($username)

Answer 2

Where is your model class? You can try this:

 <?PHP

    defined('BASEPATH') OR exit('No direct script access allowed');
    class Your_model_name extends CI_Model{
    function __construct ()
    {

        parent ::__construct();

        $this->load->database();
    }


    function signupchk($username)
    {

        $this->db->select('username');

        $this->db->from('users');

        $this->db->where('username,$username');

        $sql = $this->db->get();


        if($sql && $sql->num_rows() > 0)
        {

            return false;

        }
        else
        {
            return true;
        }

    }



    function signup($data)
    {


        $data = array(

            'rusername'=> 'username',

            'rpassword'=> 'password',

            'remail'   => 'email',

            'rphone'   => 'phone',

            'rgender'  => 'gender',

            'rqualify' => 'qualification',

        );

        $sql = $this->db->insert('users',$data);

        return $sql;

    }

    } 
}    
?>

You forget to load your model. Add this line in your insert function:

$this->load->model('Storemdl');
