<script type="text/javascript">
<!--
var divid = 'output';
var loadingmessage = '<b><font color="RED">Processing...</font></b>';
function AJAX(){
var xmlHttp;
try{
xmlHttp=new XMLHttpRequest(); // Firefox, Opera 8.0+, Safari
return xmlHttp;
}
catch (e){
try{
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP"); // Internet Explorer
return xmlHttp;
}
catch (e){
try{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
return xmlHttp;
}
catch (e){
alert("Your browser does not support AJAX!");
return false;
}
}
}
}
function formget(f, url) {
var poststr = getFormValues(f);
postData(url, poststr);
}
function postData(url, parameters){
var xmlHttp = AJAX();
xmlHttp.onreadystatechange =  function(){
if(xmlHttp.readyState > 0 && xmlHttp.readyState < 4){
document.getElementById(divid).innerHTML=loadingmessage;
}
if (xmlHttp.readyState == 4) {

document.getElementById(divid).innerHTML=xmlHttp.responseText;
}
}

xmlHttp.open("POST", url, true);
xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlHttp.setRequestHeader("Content-length", parameters.length);
xmlHttp.setRequestHeader("Connection", "close");
xmlHttp.send(parameters);
}

function getFormValues(fobj)

{
var str = "";
var valueArr = null;
var val = "";
var cmd = "";

for(var i = 0;i < fobj.elements.length;i++)

{
switch(fobj.elements[i].type)

{

case "select-one":

str += fobj.elements[i].name +
"=" + fobj.elements[i].options[fobj.elements[i].selectedIndex].value + "&amp;";
break;

}
}

str = str.substr(0,(str.length - 1));
return str;

}

//--></script>

<script type="text/javascript" language="javascript">
function submitform(){
formget(aForm, 'do.php');
}
</script>

<?
if (!empty($_REQUEST['user'])) {
$user = $_REQUEST['user'];
$user=str_replace("/","",$user);
echo "<body onload='javascript:submitform()'>";
}
?>

Basically if 'http://127.0.0.1/go.php?user=jon' then the form should automatically be submitted.

If no 'user' variable is set on the url then load the full form..

This works in IE, but not in Firefox.. any ideas ??

In Firefox nothing seems to happen !!

Thanks
