Hi! I've designed a website that works wonderfully in Firefox, Safari and Opera: www.apostlebailey.com. I still, however, am looking for a way to make the layout work in Internet Explorer (at least version 6+). Marc Coppins of NetMagikPros.com gave me some advice that I'm still working with - but if I can't get that to work, I want to try another solution: I'd like to build a version of the page that DOES work on Internet Explorer (IE), which I can easily do just working from a system that supports that browser, and have the main page (1) auto-detect incoming visitors using IE, (2) redirect those visitors to the "does-work-in-IE" (DWiIE) page, and (3) have the "does-work-in-IE" page redirect non-IE users back to the main site. In addition to the DWiIE page, I also want to create a dial-up (& maybe lower resolution) version of the page that will load more quickly (and perhaps fit on a smaller viewport/screensize). Can or should that be auto-redirected as well? My main question is about auto-redirecting on the basis of browser used though. Please let me know if you have any thoughts! -Joe Kawano

Joe, here is some PHP code that I use to detect browser versions. function detectbrowser() {global $ver, $browser; $ver = "unknown"; $browser = "unknown"; $ua = $_SERVER['HTTP_USER_AGENT'] if (($res = stripos($ua, "MSIE"))!== false) { $bs = substr($ua, $res); $res = strpos($bs, ";"); if ($res !== false) { $ver = substr($bs, 4, $res-4); } $browser = "Internet Explorer"; } if (($res = stripos($ua, "FireFox"))!==false) { $bs = substr($ua, $res); $res = strpos($bs, "/"); $ver = substr($bs, $res+1, 8); $browser = "FireFox"; } if (($res = stripos($ua, "Opera"))!==false) { $browser = "Opera"; $ver = substr($ua, $res+1, 5); } if (($res = stripos($ua, "Netscape"))!==false) { $browser = "NetScape"; $bs = substr($ua, $res); } if (($res = stripos($ua, "Safari"))!==false) { $browser = "Safari"; $res = strrpos($ua, "/", $res); $ver = substr($ua, $res+1, 3); } } detectbrowser() if ($browser == "Internet Explorer";) { include("iepage.htm"); } else { include("standard.htm"); } ? > Of course, I normally have the function definition in an include file, but the above will work just fine if your iepage.htm and standard.htm are complete pages. Then again, see this months flexible web design segment (at the meeting) and I think that you'll see that there really isn't a reason to need separate versions. Tom www.omega-link.com
