xmlHttp.open

[cody7]

Hi guys i can't get this to work

this is the onclick function

function process()
{
// only continue if xmlHttp isn't void
if (xmlHttp)
{
// try to connect to the server
try
{

var firstNumber = document.getElementById("firstNumber").value;
var secondNumber = document.getElementById("secondNumber").value;

// ($_POST)
var params = "firstNumber=" + firstNumber + "&secondNumber=" + secondNumber;
xmlHttp.open("POST", "compute.php", true);
xmlHttp.onreadystatechange = handleRequestStateChange;
xmlHttp.send(params);
}
// display the error in case of failure
catch (e)
{
alert("Can't connect to server:\n" + e.toString());
}
}
}

and this will be the compute.php

header('Content-Type: text/xml');
$firstNumber = $_POST['firstNumber'];
$secondNumber = $_POST['secondNumber'];
.....

my problem

I tried the GET approach and I make it to work so now Im trying the POST approach but

$firstNumber and $secondNumber is not getting any value. can't figure out what went wrong. please help

Are you getting an script errors? Also, try adding the following to set the request header:

XMLHttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");

no script error. but when i try to print the value of the 2 variables - no values.

Sorry I can't help with a suggestion, but I was having this EXACT same problem. I couldn't get it to actually post the data....if someone can explain how to get ajax to work with POST I'll love them..lol

Can we see the

handleRequestStateChange

handler please? Does xmlHttp have a value? Also does your PHP script actualy output anything?
