CodeIgniter：表单验证后使用uri段加载视图？

Question

On my codeigniter site I have a list of users which an admin can create content for. When creating new content for a user the url is example.com/content/new/ 5 . 5 being the ID of the user that the content is being created for. When I submit the form and form_validation fails I reload the view but the problem is that it loses that last segment on the url with the ID number. Is there a way I can reload the view with the errors and also keep that ID in the url?

Here is my code...

if ($this->form_validation->run() == FALSE){
    $this->load->view('create_content', $data); //reload if validation fails        
} else { 
    //prepare data for the database here
}

One of the ideas is to post to the same URL eg use current_url()

<?php echo form_open(current_url()); ?>
