Question

I’m new learner in CI and follow this CI simple login library (see here) in my project, everything is work pretty fine with this simple library except of if I want to add some more fields in the database table, how can I create and fetch the new added field?

This library is origin come with ‘id’, ‘username’, ’email’ and ‘password’ fields only, how if I want to add in field such as ‘address’, and make it usable in create a user $this->simplelogin->create('user', '[e-mail]', 'password', 'address', true); and fetch $this->simplelogin->get_data_user('address'); in view?

Thanks.

You can change:

• Add property

  private $address_field = ‘address’; // address in database

//Make sure that in your database must have the field address

Changge function create():

function create($user = '', $email = '', $password = '', $address = '', $auto_login = TRUE) 
{
        // Check data is set
        if ($user == '' || $password == '' || $email == '')
            return FALSE;

        // Email or User already exists | Probably will not need to check the `address`
        $this->CI->db->where($this->user_field, $user);
        $this->CI->db->or_where($this->email_field, $email);
        $query = $this->CI->db->get($this->user_table);
        if ($query->num_rows() > 0)
            return FALSE;

        // Create user into the database
        $data = array($this->user_field=>$user, $this->email_field=>$email, $this->password_field=>crypt($password, $this->salt), $this->address_field=>$address);
        if (!$this->CI->db->insert($this->user_table, $data))
            return FALSE;

        // Automatically login to created account
        if ($auto_login) {        
            $this->CI->session->sess_destroy();
            $this->CI->session->sess_create();
            $this->CI->session->set_userdata(array('username'=>$user, 'email'=>$email,'address'=>$address));
        }

        return TRUE; // Created!
    }

Changge function get_data_user():

function get_data_user($param = 'username') { // default is get session username
        $sess = $this->CI->session->userdata($param);
        if (!$sess)
            return '';

        return $sess;
    }

Change line 106 in login function:

$this->CI->session->set_userdata(array('username'=>$row[$this->user_field], 'email'=>$row[$this->email_field],'address'=>$row[$this->address_field])); // Set session data
