Hi
I'm using codeigniter 2.1.2 and I was busy doing a tutorial called How to Upload Files with CodeIgniter and AJAX, I did everything like it said but it's not uploading or saving the content.
this is the upload controller
--- Code: ---<?php
class Upload extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('files_model');
$this->load->database();
$this->load->helper('url');
}
public function index()
{
$this->load->view('upload');
}
public function upload_file()
{
$status = "";
$msg = "";
$file_element_name = 'userfile';
if (empty($_POST['title']))
{
$status = "error";
$msg = "Please enter a title";
}
if ($status != "error")
{
$config['upload_path'] = './files/';
$config['allowed_types'] = 'gif|jpg|png|doc|txt';
$config['max_size'] = 1024 * 8;
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config);
if (!$this->upload->do_upload($file_element_name))
{
$status = 'error';
$msg = $this->upload->display_errors('', '');
}
else
{
$data = $this->upload->data();
$file_id = $this->files_model->insert_file($data['file_name'], $_POST['title']);
if($file_id)
{
$status = "success";
$msg = "File successfully uploaded";
}
else
{
unlink($data['full_path']);
$status = "error";
$msg = "Something went wrong when saving the file, please try again.";
}
}
@unlink($_FILES[$file_element_name]);
}
echo json_encode(array('status' => $status, 'msg' => $msg));
}
public function files()
{
$files = $this->files_model->get_files();
$this->load->view('files', array('files' => $files));
}
public function delete_file($file_id)
{
if ($this->files_model->delete_file($file_id))
{
$status = 'success';
$msg = 'File successfully deleted';
}
else
{
$status = 'error';
$msg = 'Something went wrong when deleteing the file, please try again';
}
echo json_encode(array('status' => $status, 'msg' => $msg));
}
}
--- End code ---
This is my files_model
--- Code: ---<?php
class Files_Model extends CI_Model {
public function insert_file($filename, $title)
{
$data = array(
'filename' => $filename,
'title' => $title
);
$this->db->insert('files', $data);
return $this->db->insert_id();
}
public function delete_file($file_id)
{
$file = $this->get_file($file_id);
if (!$this->db->where('id', $file_id)->delete('files'))
{
return FALSE;
}
unlink('./files/' . $file->filename);
return TRUE;
}
public function get_files()
{
return $this->db->select()
->from('files')
->get()
->result();
}
public function get_file($file_id)
{
return $this->db->select()
->from('files')
->where('id', $file_id)
->get()
->row();
}
}
--- End code ---
This is my upload view

Noodles:
Did you get any error messages ?
Try turning on error messaging.
--- PHP Code: ---
error_reporting(E_ALL);
ini_set('display_errors', '1');
--- End code ---
Do the vars get posted properly ?
Also as this is a file upload you need to enctype the action form.
--- PHP Code: ---
<form method="post" action="<?php echo site_url('/upload/upload')?>" id="upload_file">
--- End code ---
--- PHP Code: ---<form method="post" action="<?php echo site_url('/upload/upload')?>" id="upload_file" enctype="multipart/form-data">
--- End code ---
