redirect actually sends a Location header to the browser.

Your output has already started. The server has to send the headers before any output is started. You are doing an echo before redirect. So its throwing an error as it cant send headers after output has started.

remove that echo and it should work for you.

Do not use redirect in ajax calls. You can achieve your goal with javascript redirect. Try this snippet:

if ($this->form_validation->run() == FALSE)
{
  echo "error";
}
else
{
  $this->load->model('User_model');       
  $rs=$this->User_model->register($_POST);
}

In JAVASCRIPT:

window.location = '<?php echo site_url('home'); ?>';

Its probably happening here:

echo "error";

Instead try to return the error to the caller and then display the error from the view.
