Location href not adding PHP GET address

[penislandbic]

I'm trying to use JavaScript to redirect to a PHP page that GETs a logout variable and checks to see if it's true.

This is what I have

function logout()
{
    window.location.href = "index.php?logout=true";   
}

When I invoke the logout() function, it redirects to "index.php?". It completely ignores the "logout=true" part.

How can I fix this?

that doesn't sound like a problem with javascript, but a problem with server-side settings or coding. Ex: .htaccess mod rewrite doing a redirect and not passing the query string, or code in index.php itself doing a redirect and not passing the query string

I tested it on a Liniux server from Host Gator and WAMP server on my local computer and both give the same result. I have different .htaccess files on either one.

I figured out why it wasn't working. I had the button in a form that had an onSubmit attribute. I never put return false in the function so the form refreshed the same page. It's my fault. There was nothing wrong with my server.
