Please ignore my horrible layout because I a too lazy to put my CSS in another file xD

Basically, if I take out the "requestHeader" lines the page actually does something, but when I add it the script does nothing.
I know this because when I click Send the ChatT box becomes empty. But, my PHP script is not receiving the UserMsg value I am sending to it when it actually works.

ChatFunc.php
CODE
<?php
$UserMsg=$_POST['UserMsg'];
$File=fopen("ChatT.txt", "a");
fwrite($File,$UserMsg);
fclose($File);
?>


If I set $UserMsg to a certain value, like "Hello", it writes it to the file. If I assign it to the post data it writes a "0" which Im sure means null or something.

Any tips? biggrin.gif

The site is http://tehblizzy.uuuq.com/ and the text file is (tehblizzy.uuuq.com/ChatT.txt)
(Excuse my bad language in it, I was very po'd at it at the time...)

I have no clue and have never used a doctype for anything, so I don't know the purpose of one... and where it goes.

CODE
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">


I added that to my index.php page and it didn't change anything.

At the very beginning of your code

i dunno if it has to do something with your error, or if it's how it is on your page but you should replace &lt; by <

Also, that <script></script> tag should be inside the<head></head> section.

I placed the script stuff inside the header and no changes, and the &lt; thing was just a mess up by the code thingy, its an actual < in my page

Then it's not a messup, try deleting the one you see and replacing it. Might be surprised that it works.

Yea delete the < and replace it by a <. Sometimes it's just that.

Sometimes i have errors i can't understand and just by copying my whole doc into a new page and save makes it works. Dunno why it happens but characters sometimes gets messed up.

Your code doesn't do anything, the JavaScript doesn't do anything either.

CODE
xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlHttp.setRequestHeader("Content-length", data.length);
xmlHttp.setRequestHeader("Connection", "close");

Take that out and it works, but the PHP script doesn't get the message data when you send it.

And that is my problem... everything else is fine.

-

The < isn't a problem at all so stop suggesting things about it. I already know that isn't a problem. ( I've uploaded the page MANY times and have only changed the requestHeader part of the AJAX script so I know it isn't a problem...)

I've thrown it through the excellent js debugger firebug: https://addons.mozilla.org/en-US/firefox/addon/1843

The first bug is that you use an element id that doesn't exist 'address', either rename the 'UIMessage' to 'address', otherwise change line 21:

CODE
var Data = "UserMsg=" + encodeURI(document.getElementById("address").value);


The second bug is you're using 'data' as the object name when it should be 'Data':

CODE
xmlHttp.setRequestHeader("Content-length", data.length);


Those were the ones I spotted hope that helps.

Alrighty, its basically done now. Only thing is that will freeze up if you spam it... happened once already. Another thing is, is that IE doesn't seem to like it according to a friend of mine who tried it.

Now there ish a new problem. Sessions aren't saving. I know I'm doing it right so its not my coding that has probs. The session thing may have been posted somewhere in these forums on how to fix it or why it is happening, but using the search tool comes up with too many results. SO yea, sessions don't work :'(
