vb.org Archive - View Single Post - Real-time Logo Graphic Changes in vB 3.7.4 ?

I ended up putting it in an IFRAME, and adding a META REFRESH. For anyone else who wants to do something similar, here's the new code:

Header Template Within vBulletin: (Red is the part to review or change to suit your needs.)

Code:

<!-- logo -->
<a name="top"></a>
<table border="0" width="$stylevar[outertablewidth]" cellpadding="0" cellspacing="0" align="center">
<tr><td align="center"><iframe src="http://(websitename).com/countdown.php" height="270" width="500" frameborder="0"></iframe></td></tr></table>
<!-- /logo -->
<!-- content table -->
$spacer_open
$_phpinclude_output

Revised PHP code (countdown.php):

Code:

<?php 
$target = mktime(0, 0, 0, 1, 1, 2009) ;
$today = time () ;
$difference =($target-$today) ;
$seconds =(int) ($difference) ;
if ( $seconds < "0" ) { $seconds = "0"; }
if ($seconds < 60) {
	$logo = "http://(websitename).com/images/nye/mm-logo-ny$seconds.png" ;
	}
else
	{
	$logo = "http://(websitename).com/forums/images/mm-logo-black-480x110.png" ;
	}
?>
<html><head><style type="text/css">
body
{ background: #000000; color: #ffffff; font: 10pt verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif; margin: 0px 0px 0px 0px; padding: 0px; }
</style>
<?php if ($seconds < 90) { if ($seconds > 0) {print "<meta http-equiv=\"refresh\" content=\"1\">"; } } ?>
</head>
<body>
<table border="0" width="100%" cellpadding="0" cellspacing="0" align="center">
<tr><td align="center"><?php print "<img src=\"$logo\" border=\"0\" alt=\" \" /><br />";
if ($seconds < 90) 
{ if ($seconds > 0) 
{ print "$seconds seconds remaining til New Year 2009!</td>"; }
else 
{ print "</td>"; }
}
?></tr></table>
<!-- /logo -->
</body>
</html>

Using the above code:

- Set the mktime function to the end of countdown (hours, minutes, seconds, month, day, year). You may need to adjust this for your server's timezone. If you want to display New Year's in Denver but your server is on New York time, set the mktime function for (2, 0, 0, 1, 1, 2009), which would instead trigger for 2am New York, which is Midnight in Denver.

- The "if $seconds < 90" starts refreshing the IFRAME, and displaying a countdown, roughly 30 seconds before the custom New Year logo graphics start appearing. I didn't want to go through all this work and nobody notice them. Adding the countdown seemed to be a quick way to get viewers' attention.

- The "if $seconds > 0" bit of code stops the refresh once we hit end of countdown, and also stops displaying the "__ seconds til New Year" line below the logo graphic.

My forum sees about a thousand uniques per day, and I only expect to see 20 people or so when this would be active, so the timing works for my server. If you have a busy forum, you might need to adjust the $difference calculation in the PHP code to account for lag time.
