php redirect（）无法在线服务器上运行

Question

I had redirected my page like:

redirect(base_url().'user/login/?redirect=site/cart_steps/steps');

and it works fine in localhost and when i uploaded it to server it didnt redirect. I checked all the codes and above this all code executes. But when it comes to redirect the page doesnt redirects. I also tried

redirect(base_url().'user/login?redirect=site/cart_steps/steps');
redirect(base_url().'user/login');
header('Location:'.base_url().'user/login?redirect=site/cart_steps/steps');
header('Location:'.base_url().'user/login');

but the page didn't redirect? and also i checked out this The header function is not working on online server? but it cant help me too.... can any one explain what is the problem here....

I would check your CodeIgniter error logs to verify that particular file isn't throwing any error messages that could tell you what needs fixing.

If you haven't already, you'll probably also want to make sure that the URL helper is loaded. ex:

$this->load->helper('url');
