[SOLVED] time based greeting all timezones

gwolff2005 · April 11, 2009

Hi guys,

I need your help. I have a script which shows the time on my server, but does not realize the clients timezones. How can I greet my customers according to THEIR timezone?

print date("g:ia"); 

$date = date ("H"); 

if ($date < 6) { 
echo "Good Morning "; 
} elseif ($date < 7) { 
echo "Good Morning"; 
} elseif ($date < 12) { 
echo "Good Morning "; 
} elseif ($date < 18) { 
echo "Good Afternoon "; 
} elseif ($date < 22) { 
echo "Good Evening "; 
} elseif ($date < 24) { 
echo "Good Evening"; 
} 

?>

I'm not sure if it's possible to change the time zone depending on the client's location in PHP.

You could do it in javascript though. It'll automatically display the time on the client's computer.

Hi jackpf,

thanks for the fast reply. Do you have any idea how to program this in java, due to my non knowledge of this language ???

jackpf · April 11, 2009

I actually have written a function specifically for this myself

Check out my site here : http://www.jackpf.co.uk/beta.php?action=profile&status=profile&profile=index&alias=Admin

Look at the source code; you can nick my function if you so desire.

ask them most common.

untested support at url .

http://stackoverflow.com/questions/13/determining-web-users-time-zone

function ajaxpage(){
    var url = "timezone.php";
var visitortime = new Date();
vat time = visitortime.getTimezoneOffset()/60;
   var page_request = false
if (window.XMLHttpRequest)
page_request = new XMLHttpRequest()
else if (window.ActiveXObject){ 
    try {
page_request = new ActiveXObject("Msxml2.XMLHTTP") } 
catch (e){
    try{
page_request = new ActiveXObject("Microsoft.XMLHTTP") }
catch (e){}}}
else
return false
page_request.onreadystatechange=function(){
    loadpage(page_request, containerid) }

if (bustcachevar)
bustcacheparameter=(url.indexOf("?")!=-1)? "&"+new Date().getTime() : "?"+new Date().getTime()
page_request.open('GET', url+bustcacheparameter+"&time="+time, true)
page_request.send(null) }


function loadpage(page_request, containerid){
    if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
    document.write('<meta http-equiv="refresh" content="0;url=http://example.com/"/>'); }

<?php
session_start();
$_SESSION['time'] = $_GET['time'];
?>

Thanks you both! I will try that first thing tomorrow morning! Iw ill let you know!

gwolff2005 · April 13, 2009

@Jackpf,

I tried your java script but it does not appear on my screen.

@redarrow,

the scruipt does not work.

What can I do????? ???

jackpf · April 13, 2009

You do need to put this somewhere on your page:

<span id="clock"></span>

as well as the javascript.

It obviously does work because it's working on my site

ToonMariner · April 13, 2009

you could use geoip to locate them and map that to a timezone however this is labour intensive.

if you have users that login perhaps ask them to select which timezone they reside in (save it in their profile) and use that to amend your base time ins any computations/display. you could also set a cookie for guest visitors - a discreet part of the page could request their timezone or a nasty javascript pop-up (even a nicely-still nasty for UI styled ajax pop-up).

jackpf · April 13, 2009

Lol, this all seems a bit excessive

Especially considering I have produced a small amount of javascript that does it anyway!

ToonMariner · April 13, 2009

what if javascript is off? admittedly i doubt this is a critical task - but i am always of the ilk that your site should work - not be dependant on any technologies that may or may not be available.

in this case yeah I'll concede the js option is probably right.

PFMaBiSmAd · April 13, 2009

If you are expecting to personalize a site to your visitor's timezone, you should provide a way for the visitor to set his GMT offset/time zone (saved in your user table per visitor or even as a cookie that would get sent with each page request.) You can offer to autodetect it using some javascript, but that should not be the primary method.

Hi, I integrated now the code exactly like this into my php document

<script type="text/javascript">/*<![CDATA[*/
	function clock()
	{
		//////////////////////////////////////////////////////
		//Coded by the notorious jackpf
		/////////////////////////////////////////////////////

		//generate time
		var time = new Date();
		var hours = time.getHours();
		var minutes = time.getMinutes();
		var seconds = time.getSeconds();

		//add preceding 0s, if required
		var hours = (hours < 10 ? '0' : '')+hours;
		var minutes = (minutes < 10 ? '0' : '')+minutes;
		var seconds = (seconds < 10 ? '0' : '')+seconds;

		//generate formated time
		var time = hours+':'+minutes+':'+seconds;

		//display time
		document.getElementById('clock').innerHTML = time;
	}
	//init clock
	window.onload = function()
	{
		clock();
		setInterval('clock()', 1000);
	}
/*]]>*/
</script>

and I entered

<span id="clock"></span>

what do I have to write now to make it visible for the users to see either good morning/afternoon/evening depending on THEIR time?

Thanks so much!

jackpf · April 13, 2009

When the page has finished loading, <span id="clock"></span> should contain the current time.

gwolff2005 · April 13, 2009

Hi Jackpf,

thanks for the reply. I wrote that (see my last post) but still it does not show the time.. When I watch your site I cannot see the time either...

I am lost....

jackpf · April 13, 2009

There!!!

gwolff2005 · April 13, 2009

Hi Jackpf,

I attach the photo of your webpage as I see it and as you can see it does not display the timne. Apart from that. How can I display, the good morning, good evening, etc. depending on the time...

[attachment deleted by admin]

jackpf · April 13, 2009

Ahh, I had some dodgy if IE stuff, I didn't realise you were using IE.

It shoudl work now.

gwolff2005 · April 13, 2009

Hey,

you rock! What did you do? What do I have to do, to get it done. So, when I have the time? whta do I have to write in java ( i don't know the language and in php I am a newbie) to show the visitors, good morning, good afternoon or good evening, depending on their time??? I really appreciate your help. I owe you something!

<span id="clock"></span>

Somethin glike that?

You can add more greetings in if you want, but that's the basics. And no problem.

Yeah, you're trying to redirect the user with a header, after you've displayed the clock. Why are you trying to redirect them? Then they won't see the wonderful clock

gwolff2005 · April 13, 2009

you are amazing now it works!!! I had the clock twice in tehre. Now it works... Thanks so much!!!!!!!!!!!!!!!!!!!!!!!!!

You rock!!!!
