[twitter-dev] 500 Internal Server Error when trying to Update Twitter Status

[Alex]

Hi,

I made a simple script to update a twitter status. I worked fine with
GET, but I know it would be stupid to use that because it sends
username and password in the url. I tried changing it to POST, and I
keep getting a 500 Internal Server Error whenever I try to use it.

Here's my html:

<html>
<head>
<script type="text/javascript">
var xmlhttp = new XMLHttpRequest();
function login() {

        if (xmlhttp==null) {
                        alert("Your browser doesn't support XMLHTTP!");
        }

        var url="twitupdate.php";
        var params="u=username&p=password";
        xmlhttp.open("POST", url, true);

        xmlhttp.setRequestHeader("Content-type", "application/x-www-form-
urlencoded");
        xmlhttp.setRequestHeader("Content-length", params.length);
        xmlhttp.setRequestHeader("Connection", "close");

        xmlhttp.onreadystatechange = function() {//Call a function when the
state changes.
        if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                alert(xmlhttp.responseText);
        }
}

    xmlhttp.send(params);
}

function stateChanged() {
        if (xmlhttp.readyState==4) {
                alert(xmlhttp.resonseText);
        }
}

function GetXmlHttpObject()
{
if (window.XMLHttpRequest)
  {
  // code for IE7+, Firefox, Chrome, Opera, Safari
  return new XMLHttpRequest();
  }
if (window.ActiveXObject)
  {
  // code for IE6, IE5
  return new ActiveXObject("Microsoft.XMLHTTP");
  }
return null;
}
</script>
</head>
<body>
<input type="text" id="username" />
<input type="text" id="password" />
<input type="button" onclick="login()" value="Login"/>
</body>
</html>

Here's My PHP:

<?php
$tweettext = $_POST["
require "Twitter.class.php";

$tweet = new Twitter($_POST["u"], $_POST["p"]);

$success = $tweet->update("yay!");
if ($success) echo "Tweet successful!";
else echo $tweet->error;

?>
