Re: Most portable back button in php

Thanks, I'll have a go. In answer to the question about the browsers back button; sometimes that may not be visible either because the user has setup the browser that way or because a window has been opened without it. It is accepted, however, that since javascript would be needed to open a window without the browsers back button (if the user configuration had it showing), then a javascript solution would be fine. Basically I'm just trying to be "completely" portable, a tall order I know but easier to attain server side!!
