Question

我是CI的新学员，并且在我的项目中关注这个CI简单登录库(see here)，除了我想在数据库表中添加更多字段之外，这个简单库的一切都很好用，如何创建和获取新添加的字段？

此库的来源仅包含'id'，'username'，'email'和'password'字段，如果我想在'address'等字段中添加，并使其可用于创建用户{ {1}}并在视图中获取$this->simplelogin->create('user', 'user@mail.com', 'password', 'address', true);

感谢。

您可以更改：

添加属性

private $ address_field ='address'; //数据库中的地址

//确保您的数据库中必须包含字段address

长葛功能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!
    }

长葛函数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;
    }

在登录功能中更改第106行：

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

我担心没有简单的方法可以做到这一点

你需要将库Simplelogin.php修改为类似的东西请记住，您需要将地址字段添加到表
