Image handling and upload

Once the file is uploaded, you can either crop it to a square using the image library, or use getimagesize() to get the image dimensions and see if it's square.

Another observation, it would be wiser to call $this->session->set_userdata() once. If you are storing your sessions in the database, or ever decide to, an update will be fired at the database once for each call to $this->session->set_userdata().

Code:

$this->session->set_userdata(array(
    'name' => $data['name'],
    'username' => $data['username'],
    'address' => $data['address'],
));

Thanks! Another thing, is there any way I can check if there's a file to upload? Something like:

Code:

if (theres_file_to_upload)
{
    // run this only if the user selected a file to upload
}
