Check your $error_msg_reply if it is equal to ( 'upload_no_file_selected' )

That is the error message returned, use an if else statement to check for it.

You can make a condition check like:

Code:

if ($this->upload->do_upload('userfile'))
{
    $upload_data = $this->upload->data();
    # upload logic ...
}

I use this detection of whether a file is going to be uploaded, it always works:

Code:

$field = 'userfile'; // The name attribute of the file input control.
$file_selected = isset($_FILES[$field]) && isset($_FILES[$field]['name']) && $_FILES[$field]['name'] != '';
