I think most warnings come from these contructs. I have
a look if there is another way to avoid these warnings.


  If there's a risk that that variable doesn't exist, it
should probably be:

  if (isset($navigation_check) && $navigation_check) {
  }

  There are a variety of such checking mechanism's in PHP.

This has probably already been checked, but the other obvious thing is to check if they are POST or GET variables, in which case you need $_POST["variablename"] instead of just $variablename in PHP installs configured that way.
