The problem was the PHP code was refering to the passed in paramaters in the local scope, and not as $_GET['']. Sorry about that folks - it has now been updated and works again. The older version would still have worked if register_globals was on - but we all know that is not the most secure way to code...lol.

I think that there is something I missed. Should I configure the php.ini or httpd.conf files? Please help. Thanks.

var response = http.responseXML.documentElement;

I’m currently having a nightmare with AJAX because of something around this area of the script. I can get the data I need, and responseText returns exactly what I requested, but I need it in XML to be able to parse it. My returned XML does return “object XML Document” when I run a typeof on the variable, but for some reason I can’t walk through it pull data out.

[...]
http.onreadystatechange = function () {
if (http.readyState == 4) {
if (http.status == 200) {
response = http.responseXML.documentElement;
check(yti_response);
} else {
alert('Some sort of server error message here');
}
}
}
http.send(null);
}

function check(response) {
status = response.getElementsByTagName("tagname")[0].firstChild.nodeValue;
alert(status);
[...]

It’s all syntactically correct, but for some reason the script just stops running (or gets stuck) when I try to getElementsByTagName. The weirdest thing is that Firefox doesn’t return any kind of JS error whatsoever.

Even stranger is that with .documentElement added to the http.responseXML the script stops running there.

Anyone have any ideas? I’m going crazy…
