Re: [phplib] [for Menu Bar] creation of GIF image buttons in PHP - won't accept more than one word From: Stephen Woodbridge (woodbri <email protected>)
Date: 05/29/01

The label is getting passed to 17-1.php as an argument via the url. You
have to url encode the label because of the space and possible other
special characters.
