[RESOLVED] Ajax Issue

NZ_Kiwis

I would have thought that this update each day, Christmas Day, Boxing Day, 27th etc each time I changed the name. It does not. Why??

index.php

<script language="javascript" type="text/javascript">
<!-- 
//Browser Support Code
function ajaxFunction(){
	var ajaxRequest;  // The variable that makes Ajax possible!

try{
	// Opera 8.0+, Firefox, Safari
	ajaxRequest = new XMLHttpRequest();
} catch (e){
	// Internet Explorer Browsers
	try{
		ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
	} catch (e) {
		try{
			ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
		} catch (e){
			// Something went wrong
			alert("Your browser broke!");
			return false;
		}
	}
}

// Create a function that will receive data sent from the server
ajaxRequest.onreadystatechange = function(){
	if(ajaxRequest.readyState == 4){
		document.myForm.time.value = ajaxRequest.responseText;
	}
}

var CurrentDate = document.getElementById('time').value;

ajaxRequest.open("GET", "serverTime.php?Date=" + CurrentDate, true);
ajaxRequest.send(null); 
}
//-->
</script>

</head>

<body onLoad="OnPageLoad()">

Welcome, 

<form name='myForm'>
Name: <input type='text'  onChange="ajaxFunction();" name='username' /> <br />
Time: <input name='time' type='text' id='time' size="100" />
</form>

SeverTime.php

<?php
if (!isset($_GET['Date'])){
	$GameDate = $_GET['Date'];
} else {
	$GameDate = "24-12-1980";
}
$GameDate = strtotime('+1 day', strtotime ($GameDate));
$GameDate = date('j-m-y', $GameDate);
echo $GameDate;
?>

Couple problems I see:

What month is the date 01-02-2011 in? If you said Februrary, how do you know I didn't mean January 2nd? Or vice versa?

In other words, your date format is a rather poor choice - perhaps a more standard format of YYYY-MM-DD might work better.
This code makes no sense:
```
if (!isset($_GET['Date'])){ 
    $GameDate = $_GET['Date']; 
}
```
considering that the only time that $_GET['Date'] will be used is if it doesn't exist.

If that's all ServerTime.php is doing, then what is the point of using the server at all? All it's doing is adding one day to the time supplied by the client - something which could be done using JavaScript's date/time functionality on the client.
