Issue with file upload - php

Question

//views/myproject/testupload.php
<a class="btn pull-right btn btn-primary"
href="<?= site_url("myproject/upload/") ?>"><?= lang('upload') ?></a>
//views/myproject/upload.php
<?php echo form_open_multipart(site_url('myproject/do_upload'));?>
<?=form_line('', form_upload('userfile', $this->form_validation->set_value('userfile')));?>
<?=form_submit('upload', lang('action_upload'), 'class="btn btn-primary"');?>
<?php echo form_close();?>
//Controller/myproject/test.php
public function upload()
{
$this->output->view('analytics/kysim/upload');
}
public function do_upload()
{
$config['upload_path'] = 'C:/test/';
$config['allowed_types'] = 'txt';
$this->load->library('upload', $config);
$name_file = $_FILES['userfile']['name'];
if ( ! $this->upload->do_upload($name_file))
{
$error = array('error' => $this->upload->display_errors());
var_dump($error);
die();
//$this->load->view('upload', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
var_dump($data);
die();
//$this->load->view('success', $data);
}
}
I am not able to upload a file to a specified location(C://test).var_dump($name_file) displays the uploaded file name.
$this->upload->do_upload($name_file) returns false and so var_dump($error) displays the error message "error" => "<p>You did not select a file to upload.</p><p>You did not select a file to upload.</p>""
Any help on uploading the file to specified location(C://test) would be appreciated.

Hope this will help you :
Note : make sure your c drive has test folder which in turn have writable permission
Your do_upload method should be like this :
public function do_upload()
{
$config['upload_path'] = 'C:\test\\';
$config['allowed_types'] = 'txt';
$this->load->library('upload', $config);
if (! empty($_FILES['userfile']['name']))
{
if ( ! $this->upload->do_upload('userfile'))
{
$error = array('error' => $this->upload->display_errors());
var_dump($error);
die();
}
else
{
$data = array('upload_data' => $this->upload->data());
var_dump($data);
die();
}
}
}
Your form should be like this :
<?php
echo form_open_multipart('myproject/do_upload');
echo form_line('', form_upload('userfile', $this->form_validation->set_value('userfile')));
echo form_submit('upload', lang('action_upload'), 'class="btn btn-primary"');
echo form_close();
?>
