Better than if(count($_POST) > 0)

I want to check if POST occurred or not. Currently I'm using code below. I wonder if there is a better way of doing it with CI?

Thanks

Code:

do_save()
{
   if(count($_POST) > 0)
   {
      //Validate fields with form validator
   }
   else
   {
      redirect('index');
   }
}

form_validation class already including the POST inspection within its procedure, so this is more than enough :

Code:

function do_save()
{
   // Set validation rule
   // ...

   if($this->form_validation->run())
   {
      // save
   }
   else
   {
      redirect('index');
   }
}
