Codeigniter ion auth trying to get the user name of a logged in user in to a string

提问by 1ftw1

Hi team i am new to CI and ion auth and i want to find the best way to get the user name on the logged user and make it a string. I have try this and im getting an error.

嗨，团队，我是 CI 和 ion auth 的新手，我想找到在登录用户上获取用户名并将其设为字符串的最佳方法。我已经尝试过这个，但出现错误。

Object of class CI_Email could not be converted to string

类 CI_Email 的对象无法转换为字符串

This is my Controller

这是我的控制器

 class Dashboard extends CI_Controller {

    function index() {
        $user = $this->ion_auth->user();
        $email = $user->email;  

        $data['email']= $email;
        $data['mainContent'] = 'dashboard_view';
        $this->load->view('template', $data);
    }

and view

并查看

<div id='dashboarWap'>
    <?php echo form_open('dashboard/dashInput'); ?> 

    <?php echo $email; ?>

Any idea on why i am getting this error would be a big help thanks.

关于为什么我会收到此错误的任何想法都会有很大帮助，谢谢。

$this->ion_auth->user()is a DB object.

$this->ion_auth->user()是一个数据库对象。

$this->ion_auth->user()->row();returns the user object which you can query for first_name, number_of_cats_owned, or whatever.

$this->ion_auth->user()->row();返回您可以查询 first_name、number_of_cats_owned 或其他内容的用户对象。

Ion Auth sets the username, email, user id, and last login time in session variables when the user logs in (have a look at ln 683 ish in the ion_auth_model'slogin function.)

当用户登录时，Ion Auth 在会话变量中设置用户名、电子邮件、用户 ID 和上次登录时间（查看ion_auth_model 的登录函数中的 ln 683 ish 。）

The simplest way to get this info is by using CI's session classlike so:

获取此信息的最简单方法是使用CI 的会话类，如下所示：

$username = $this->session->userdata( 'username' );

Of course, I abuse helpers so to make this even simpler I'll normally use a variant of this helper function:

当然，我滥用助手，所以为了让这更简单，我通常会使用这个助手函数的一个变体：

function userdata( $key, $val = null ){
  $ci = &get_instance();
  if ( $val !== null ){
    $ci->session->set_userdata( $key, $val );
  } else {
    return $ci->session->userdata( $key );
  }
}

This gives us a handy (& global scoped) function to call on as needed, wherever needed:

这为我们提供了一个方便的（和全局范围的）函数，可以根据需要在任何需要的地方调用：

$username = userdata( 'username' );

Ion auth already passes any data on logged in user through

Ion auth 已经通过了登录用户的任何数据

$this->data['users'] = $this->ion_auth->users()->result();

You can access user name by doing this

您可以通过执行此操作访问用户名

foreach ($users as $value) {
    echo $value->first_name. " " . $value->last_name;
}
