why codeigniter do_upload doesn't work on server? - codeigniter

Question

I have used codeigniter do_upload to upload mp3 files on a directory on server.
my codes work perfectly on localhost but on production server just browser keeps waiting for server and processing and nothing happens after a long time.
$dirpath in following code is the path of destination directory on server.
$data['info']=$this->cp_model->GetInfo($service_id);
$dirpath = '/var/li/sounds/'.$data['info'][0]->path;
$config = array('allowed_types' => 'mp3' ,
'upload_path' => $dirpath,
'overwrite' => FALSE,
'max_size' => 0,
);
$this->load->library('upload',$config);
}
if (isset($_POST['submit'])) {
$this->upload->do_upload();}

Answer 1

Most probably you don't have write permissions on the folder declared on your $dirpath. Also consider that uploading an mp3 that may be 4-5 MB server side, can take some minutes depending your connection.
To find out what your problem is whatsoever, output your error by checking the do_upload() method.
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}

Your script works everywhere beside "Local" server
Now I had the same problem, tested it in Hosting Web Server, and it worked. If u wanna the code, here u are:
public function do_upload()
{
$config['upload_path'] = './img';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '1000';
$config["encrypt_name"] = true;
$config["remove_spaces"] = true;
$this->load->library('upload', $config);
$this->upload->initialize($config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_view', $error);
}
else
{
echo "SUCCESS";
}
}
