我读到关于闪存数据的堆栈溢出仅在下一个服务器请求之前有效，因此我为几个消息显示制作了新的闪存数据。下面是我的代码
这是我的控制器控制器
public function login(){
$this->form_validation->set_rules('username','Username','required');
$this->form_validation->set_rules('password','Password','required|min_length[5]');
if($this->form_validation->run() == TRUE){
$username= $this->input->post('username');
$password= $this->input->post('password');
$this->load->model('Auth_model');
$user = $this->Auth_model->get_login();
if ($user == 0) {
//echo "<script>alert('wrong username');</script>";
$this->session->set_flashdata("msg","Username does not exists");
redirect("auth/login");
}
else{
print_r($user['username']);
if($username == $user['username'] && $password == $user['password']){
$this->session->set_flashdata("success","You are logged in");
$_SESSION['user_logged'] = TRUE;
$_SESSION['username'] = $user['username'];
redirect("user/dashboard","refresh");
}
else {
//echo "<script>alert('wrong password');</script>";
$this->session->set_flashdata("msg","Password does not match.");
redirect("auth/login");
}
}
}
$this->load->view('login_v');
}
模型
public function get_login(){
$username = $this->security->xss_clean($this->input->post('username'));
$password = $this->security->xss_clean($this->input->post('password'));
$this->db->select('*');
$this->db->from('users');
$this->db->where(array('username' => $username));
$query = $this->db->get();
$user = $query->row();
if ($this->db->affected_rows() != 1) {
return false;
}
else {
$data = array(
'user_id' => $user->user_id,
'username' => $user->username,
'password' => $user->password
);
//print_r($data);
//$this->session->set_userdata($data);
return $data;
}
}
看法
<?php if(isset($_SESSION['success'])) {?>
<div class="alert alert-success"><?php echo $_SESSION['success']; ?></div>
<?php } ?>
<?php echo validation_errors('<div class="alert alert-danger">', '</div>'); ?>
<?php $this->session->flashdata('msg');?>
<form action="" method="POST">
<div class="form-group">
<label for="username">Username</label>
<input type="text" class="form-control" name="username" id="username">
</div>
<div class="form-group">
<label for="password">Password:</label>
<input type="password" class="form-control" name="password" id="password">
</div>
<div>
<button class="btn btn-primary" name="login">Login</button>
</div>
</form>
我要显示
$this->session->set_flashdata("msg","Username does not exists");
但我的 if else 只是做重定向，但注释的脚本标签工作正常。
如何使“味精”工作？
提前致谢。
