Re: Output (Urgent!)

You aren't getting the value to the PHP script... allow me to walk through what is actually happening $resolution = "<SCRIPT LANGUAGE=\"JavaScript\">document.write(screen.width)</SCRIPT>"; echo "--".$resolution."--"; You have just set a variable to "<SCRIPT LANGUAGE=\"JavaScript\">document.write(screen.width)</SCRIPT>" and then echoed that string. so it looks like you have --1024-- or whatever your resolution is. if you view source though you see you really have --<SCRIPT LANGUAGE=\"JavaScript\">document.write(screen.width)</SCRIPT>-- and the client browser is just interpreting that JavaScript statement if (($resolution*1) >= 1024) { $resolution = "1024"; } else { $resolution = "800"; } echo "**".$resolution."**"; The reason this isn't acting the way you expect is because you AREN'T saying if ((1024*1) >= 1024 { You are actually saying if ((<SCRIPT LANGUAGE=\"JavaScript\">document.write(screen.width)</SCRIPT>*1) >= 1024) { You are not actually passing anything from JavaScript to PHP... you are just tricking yourself =) Sheridan ----- Original Message ----- From: Morten Winkler Jørgensen <madmax@mip.sdu.dk> To: <php-general@lists.php.net> Sent: Tuesday, July 17, 2001 4:54 AM Subject: Re: [PHP] Output (Urgent!) > > >> How you want to get a value from client side to php on the same page? > > Well.
