我正在尝试从数据库中获取用户详细信息并将其放入会话中,以便可以在视图中使用它。我尽我所能,但我一直在收到错误。未定义的可变电子邮件。
MODEL :
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;
} else {
return array();
}
} else {
return array();
}
}
CONTROLLER :
function isLoggedIn()
{
$isLoggedIn = $this->session->userdata('isLoggedIn');
$data['title'] = 'Login';
if(!isset($isLoggedIn) || $isLoggedIn != TRUE)
{
$this->load->view('templates/header');
$this->load->view('users/login', $data);
$this->load->view('templates/footer');
}
else
{
redirect('posts');
}
}
/**
* This function used to logged in user
*/
public function login()
{
$this->load->library('form_validation');
$data['title'] = 'Login';
$this->form_validation->set_rules('username', 'Username', 'required|max_length[128]|trim');
//$this->form_validation->set_rules('password', 'Password', 'required|max_length[32]|');
if($this->form_validation->run() === FALSE)
{
$this->load->view('templates/header');
$this->load->view('users/login', $data);
$this->load->view('templates/footer');
}
else
{
$username = $this->input->post('username');
$password = $this->input->post('password');
$result = $this->user_model->login($username, $password);
if(count($result) > 0)
{
foreach ($result as $res)
{
$sessionArray = array('id'=>$res->id,
'username'=>$res->username,
'email'=>$res->email,
'mobile'=>$res->mobile,
'isLoggedIn' => TRUE
);
$this->session->set_userdata($sessionArray);
$this->session->set_flashdata('user_login', 'Welcome');
redirect('posts');
}
}
else
{
$this->session->set_flashdata('login_fail', 'Email or password mismatch');
redirect('users/login');
}
}
}
查看:
<?php echo $email; ?>
答案 0 :(得分:2)
您正在为用户信息创建会话
尝试获取会话数据:
echo $ this-&gt; session-&gt; userdata('email');
或尝试传递views $ data
中的数据答案 1 :(得分:2)
$ email不起作用,因为写$ email意味着普通变量,但在你的情况下,你必须写如:
<?php echo $this->session->userdata('email'); ?>
答案 2 :(得分:0)
如果您使用的是flashdata,那么您可以使用以下代码获取它:
<强>控制器强>
if (empty($this->session->userdata('UserID'))) {
$this->session->set_flashdata('flash_data', 'You don\'t have access!');
$this->load->view("initialHeader");
$this->load->view("login");
redirect('Login');
}
查看强>
<?php if(!empty($this->session->flashdata('flash_data'))) {
?>
<div class="alert alert-danger">
<?php echo $this->session->flashdata('flash_data'); ?>
</div>
<?php } ?>
如果您使用tmp数据作为会话,请参阅以下代码:
<强>控制器强>
<?php
if (!empty($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, $data));
} ?>
查看强>
<?php if ($this->session->tempdata('permission_error_msg')) { ?>
<b class="login_error_msg"><?php
if (!empty($this->session->tempdata('permission_error_msg'))) {
echo $this->session->tempdata('permission_error_msg');
}
?></b>
<?php } ?>
谢谢。
