gevans Posted April 21, 2009 Share Posted April 21, 2009 The problem's with your ajax, try asking in the javascript section.... Once that's sorted you may need to revise the php also Link to comment https://forums.phpfreaks.com/topic/155111-solved-double-drop-down-from-db/#findComment-815971 Share on other sites More sharing options...

soak Posted April 22, 2009 Share Posted April 22, 2009 You're calling findcity.php but you indicate your file is called findCity.php. If you're on Windows this will be fine but not on nix. There's nothing obvious wrong with your javascript. What happens if you view findcity.php?id=1 in your browser?
