A simplified version of this would be: $glb_http_ref = isset( $_SERVER['HTTP_REFERER'] ) ? $_SERVER['HTTP_REFERER'] : "";
or just: $glb_http_ref = @$_SERVER['HTTP_REFERER']; The latter will suppress the error message and return a null (or a blank as far as PHP is concerned. Not the cleanest route and I prefer the first method, but just thought I would get some options out there. :) On 1/7/06, Gerry Danen <[EMAIL PROTECTED]> wrote: > > On 1/7/06, Kevin Waterson <[EMAIL PROTECTED]> wrote: > > > > This one time, at band camp, Gerry Danen <[EMAIL PROTECTED]> wrote: > > > > > I'm wondering if $_SERVER['HTTP_REFERER'] is no longer supported, or > > perhaps > > > has a new name? > > > > still there, same name. > > > > print_r($_SERVER); > > > Ah, yes.
