以前我使用OpenServer并使用CodeIgiter开发了一个小型登录应用程序，一切都运行良好。但后来由于某些原因我将服务器更改为Xampp并将所有控制器，视图，模型和数据库复制到xammp服务器。我在配置文件和自动加载文件中进行了所有必要的更改。但是当从那里跑时我会遇到很多致命的错误。此外，不显示我通过flash-data（）设置的form_validation错误。
你能否在这方面帮助我？家庭控制器
<?php
class Home extends CI_Controller
{
public function index ()
{
$data['main_view']= "home_view";
$this->load->view('Layouts/main',$data);
}
}
?>
用户控制器
类用户扩展了CI_Controller {
public function show()
{
$this->load->model('user_model');
$data['reslt']= $this->user_model->get_users(3);
// $this->load->view('user_view',$data);
foreach( $data['reslt'] as $objec)
{
echo $objec->Username;
}
}
public function addUser()
{
$uname="Mursal";
$upass="Not good for you";
$this->load->model('user_model');
$this->user_model->create_user(['username'=>$uname,
'UserPassword'=>$upass],$id);
}
public function updateUser()
{
$id=3;
$uname="Mursal";
$upass="Not good for you";
$this->load->model('user_model');
$this->user_model->update_users(['Username'=>$uname,
'UserPassword'=>$upass],$id);
}
public function deleteUsers($id)
{
$this->load->model('user_model');
$this->user_model->delete_user($id);
}
public function login()
{
//echo $_POST["username"];
//echo $this->input->post('username');
$this->load->model('user_model');
$this->form_validation->set_rules('username','User Name', 'trim|required|min_length[3]');
$this->form_validation->set_rules('password','Password','trim|required|min_length[3]');
$this->form_validation->set_rules('confrm_pass','Confirm Password','trim|required|matches[password]');
if($this->form_validation->run()==false)
{
$data=array(
'errors'=>validation_errors()
);
$this->session->set_flashdata($data);
redirect('home');
}
else
{
$name=$this->input->post('username');
$pass=$this->input->post('password');
$userid=$this->user_model->log_in($name,$pass);
if($userid)
{
$usrdata=array(
'user_name'=>$name,
'user_pass'=>$pass,
'loged_in'=>true
);
$this->session->set_userdata($usrdata);
$this->session->set_flashdata('login_success','You are now logged in');
$data['main_view']="admin_view";
$this->load->view('Layouts/main',$data);
//redirect('home/index');
}
else
{
$this->session->set_flashdata('login_failed','Sorry');
redirect('home/index');
}
}
}
public function log_out()
{
$this->session->sess_destroy();
redirect('home/index');
}
}
?>
用户模型
类User_model扩展了CI_Model {
public function log_in($name,$pass)
{
$this->db->where('Username',$pass);
$this->db->where('UserPassword',$pass);
$reslts=$this->db->get('users');
if($reslts->num_rows()==1)
{
return $reslts->row(0)->ID;
}
else
{
return false;
}
}
}
?>

如果用户紫罗兰形成验证规则，则应在此处显示Flash数据错误，但不起作用。

将其置于控制器中
if ($this->form_validation->run() == FALSE) {
$errors = validation_errors();
$this->session->set_flashdata('form_error', $errors);
$this->load->view('Your View page');
}
将其放置在您的视图页面
<?php if($this->session->flashdata('form_error')): ?>
<?php echo $this->session->flashdata('form_error');?>
<?php endif; ?>
我希望这会对你有所帮助..！
