代码点火器 - 登录在 if 部分中不起作用

Question

当我输入数据时，我的登录不起作用，它将始终恢复为登录视图...我创建它，所以如果我输入数据，它会转到前面/主页，但不知何故，if in 函数登录不起作用，并且总是将其更改为其他...

控制器：登录.php

class Login extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->library(array('session', 'form_validation'));
$this->load->helper(array('url', 'form'));
$this->load->model("Member_model");
}
public function loginMember() {
$this->form_validation->set_rules('username','Username','required');
$this->form_validation->set_rules('password','Password','required');
if ($this->form_validation->run($this) == FALSE) {
$this->load->view('front/login');
} else {
//enter username and password
$username = $this->input->post('username');
$password = $this->input->post('password');
$this->load->model('Member_model');
$member = $this->Member_model->checkLogin($username, $password);
if ($member) {
$id_member = $this->Member_model->get_member_id_from_username($username);
$member    = $this->Member_model->get_member($id_member);
//set session variables
$_SESSION['id_member']   = $member->id;
$_SESSION['logged_in']   = true;
$_SESSION['username']    = $member->username;
//redirect
redirect('Member/profile');
} else {
print_r('User doesnt exist');                
}
}
}
//logging out of a user
public function logoutMember() {
if (isset($_SESSION['logged_in']) && $_SESSION['logged_in'] === true) {
foreach ($_SESSION as $key => $value) {
unset($_SESSION[$key]);
}
redirect('Member/Login');
}
}

}

控制者：成员.php

public function profile() {
if (isset($_SESSION['user_logged']) && $_SESSION['user_logged'] !== true) {
$this->session->set_flashdata("error","Please login first to view");
redirect('Member/Login');
} else{
$this->load->view('front/home');
}
}

型号：Member_model.php

public function checkLogin($username, $password) {
$this->db->select('password');
$this->db->from('member');
$this->db->where('username', $username);
$hash = $this->db->get()->row('password');
return $this->verify_password_hash($password, $hash);
}
public function get_member_id_from_username($username) {
$this->db->select('id');
$this->db->from('member');
$this->db->where('username', $username);
return $this->db->get()->row('id');
}
public function get_member($id_member) {
$this->db->from('member');
$this->db->where('id', $id_member);
return $this->db->get()->row(); 
}
private function hash_password($password) {
return password_hash($password, PASSWORD_BCRYPT);   
}

private function verify_password_hash($password, $hash) {
return password_verify($password, $hash);   
}

查看：登录.php

<form method="post" action="<?php echo site_url('Login/loginMember'); ?>" >                        
<input class="text" type="text" id="username" name="username" placeholder="Your username"><br>
<input class="text" type="password" id="password" name="password" placeholder="Your password">
<input type="submit" value="Login">
</form>
<p>Don't have an Account? <a href="<?php echo site_url('Member/Register'); ?>"> SignUp NOW!</a></p>

我认为问题出在这段代码中：

if ($this->form_validation->run($this) == FALSE) {
$this->load->view('front/login');
} else {
//enter username and password
$username = $this->input->post('username');
$password = $this->input->post('password');
$this->load->model('Member_model');
$member = $this->Member_model->checkLogin($username, $password);
if ($member) {
$id_member = $this->Member_model->get_member_id_from_username($username);
$member    = $this->Member_model->get_member($id_member);
//set session variables
$_SESSION['id_member']   = $member->id;
$_SESSION['logged_in']   = true;
$_SESSION['username']    = $member->username;
//redirect
redirect('Member/profile');
} else {
print_r('User doesnt exist');                
}
}

因为，在我输入数据后，它会打印出用户不存在......即使我输入的数据看起来就像数据库中的数据。

在成员控制器中更改 if 条件。您忘记了其中的"="。

if ($_SESSION['user_logged'] == FALSE)

并检查您的会话变量是否存储数据。
