Ajax post vars not seen in PHP script

I am trying to initiate an ajax post call to a php script where it will update some values in my database.

The problem I have is, the POST values are not seen in my php script, or at least I have no response.

Here is my javascript:

<script type="text/javascript">
$("btnOpsb" ).onclick = pinOpsb;
function pinOpsb(){
var params = "wxdata = test";
var ajaxRequest;
try{ajaxRequest = new XMLHttpRequest();} catch (e){try{ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");} catch (e) {try{ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");} catch (e){alert("Error: Browser/Settings conflict");return false;}}}
    ajaxRequest.onreadystatechange = function(){
        if(ajaxRequest.readyState == 4){
            alert(ajaxRequest.responseText);
        }
    }
    ajaxRequest.open("POST","wx2strip.php",true);
    ajaxRequest.setRequestHeader("Content-type","application/x-www-form-urlencoded");
    ajaxRequest.send("fname=Henry&lname=Ford");
}
</script>

In my wx2strip.php I have tried echo back something if $_POST had anything in it, but even when I just echo something at the top of the script and exit, there is still no response in the alert I created.

I tried using get, and I do get a response back.

Any help would be appreciated, thanks.

I suspect that Aerik's answer is correct about why you are experiencing problems.

That said, since you are already using jQuery in your javascript, I believe you will simplify things quite a bit if you look into using jQuery's $.post(). It will handle all of these types of complications for you, so if there are any other small issues like that, you won't run into problems.

Add these two lines to set the right headers:

ajaxRequest.setRequestHeader("Content-length", "fname=Henry&lname=Ford".length);
ajaxRequest.setRequestHeader("Connection", "close");

Content-length is required for POST.
