Uploading an image with Code Igniter? - codeigniter

Question

I'm trying to set a site up so I can upload images using a web form in Code Igniter(CI). I'm not getting any errors but the file is not being saved either. I wanted to know if those that were successful in uploading images could help explain what might be the issue?
View:
<?php
echo form_open_multipart('admin/galleryUpload') . "\n";
echo "<div class='span-8'><span class='text'>Image:</span>" . form_upload('uploadImg') . "</div>";
foreach ($gallery as $picture)
{
$order[] = $picture->order;
}
$order[] = count($order) + 1;
echo "<div class='span-6 last'><span>Image Order #:</span>" . form_dropdown('order', $order) . "</div><div class='span-14'> </div>";
$conf = array('name' => 'alt_text', 'size' => '75');
echo "<div class='span-14 last'><span>Discription:</span>" . form_input($conf) . "<br /></div>";
echo form_hidden('propertyID', "$propertyID");
echo form_submit('upload', 'Upload');
echo form_close();
?>
Controller:
class Admin extends Controller
{
function galleryUpload()
{
if (! $this->session->userdata('is_admin'))
{
redirect('admin/index');
}
else
{
$this->load->model('admin_model');
$this->admin_model->imgUpload();
}
}
}
Model:
class Admin_model extends Model
{
function imgUpload()
{
$id = $this->input->post('propertyID');
$order = $this->input->post('order');
$alt_text = $this->input->post('alt_text');
$config = array(
'allowed_types' => 'jpg|jpeg|gif|png',
//'upload_path' => '../' . $this->imgPath($id),
'upload_path' => '../img/galleries/temp/',
'max_size' => '5000', // 5MB files max
);
$this->load->library('upload', $config);
$this->upload->do_upload();
$image_data = $this->upload->data();
$config = array(
'source_image' => $image_data['full_path'],
'new_image' => $this->imgPath($id) . '/thumbs',
'maintain_ratio' => TRUE,
'width' => '60'
);
$this->load->library('image_lib', $config);
$this->image_lib->resize();
}
}

From the user guide:
By default the upload routine expects the file to come from a form
field called userfile, and the form must be a multipart type
So you either have to change the name of the form field to userfile:
form_upload('userfile')
or pass the name of your form field to do_upload:
$this->upload->do_upload('uploadImg');
