Php 将用户信息传递到codeigniter中的视图

我试图从数据库中获取用户详细信息，并将其放入会话中，以便在视图中使用。我已经尽了我所能，但我总是出错。未定义的变量电子邮件

型号：

function login($username, $password)
    {
        $this->db->select('authTbl.id, authTbl.password, authTbl.username, authTbl.email, authTbl.mobile');
        $this->db->from('users as authTbl');
        $this->db->where('authTbl.username', $username);
        $this->db->where('authTbl.isDeleted', 0);
        $query = $this->db->get();

        $user = $query->result();

        if(!empty($user)){
            if(verifyHashedPassword($password, $user[0]->password)){
                return $user;

您正在为用户信息创建会话

尝试获取会话数据：

echo$this->session->userdata（'email'）

---

或者尝试在视图$data中传递数据

您正在为用户信息创建会话

尝试获取会话数据：

echo$this->session->userdata（'email'）

或者尝试在views$data中传递数据，如果您使用的是flashdata，则可以使用以下代码获取：

控制器

if (empty($this->session->userdata('UserID'))) {
            $this->session->set_flashdata('flash_data', 'You don\'t have access!');
            $this->load->view("initialHeader");
            $this->load->view("login");
            redirect('Login');
        }

<?php 
if (!empty($data)) {
            $this->session->set_userdata('permission_error_msg', $data);
            $this->session->mark_as_temp('permission_error_msg', 10); // For 10 Seconds
            $this->load->view('dashboard', array($title, $data));
        } ?>

查看

$email将不起作用，因为写$email意味着普通变量，但在您的情况下，您必须这样写：

<?php echo $this->session->userdata('email'); ?>
