[RESOLVED] redirecting if switch is empty

[bastienvans]

Hello everyone,

Let's say my URL is www.example.com/admin.php?p=foo

switch ($p){
	case "foo":
		echo "foo";
		break;
	case "bar":
		echo "bar";
		break;	

how do I redirect a user if they enter, "www.example.com/admin.php" to "www.example.com/admin.php?p=foo"

Thanks

switch($p)
{
// various cases, then...
   default:
      header("Location: http://example.com/foo.php");
      exit;
}

switch{
case
case
case
default
}
The 'default :' is used if there was no match in other 'case'

<?php

switch ($p){
	case "foo":
		echo "foo";
                include 'foo.php';
		break;
	case "bar":
		echo "bar";
                include 'bar.php';
		break;
        default :
                header('location: admin.php?p=foo');
                exit(); // stop for default case
}
exit(); // stop, foo and bar case, after those include

?>

How would you solve this one?

I have this at the top of my page, which redirects the user if they are not logged in:

<?php
session_start(); 
	if(!isset($_SESSION['myusername'])) {
		header("location: index.php");
		exit();
	}
?> 

I am getting "Warning: Cannot modify header information - headers already sent by blah blah" since I have two header:location.

How do I get two header:location in there?

thanks again
