Adapting My Holiday Logo Rotator for WordPress

Welcome to my blog, please feel free to subscribe to my RSS feed or leave a comment.

The other day I wrote a tutorial on how to rotate your logo on holidays and since then I’ve had a few people email me and ask how to this specifically for WordPress using the standard Themes structure. In order to accomplish this for WordPress specific blogs, you’ll need to make a few minor changes to my original code.

First, you’ll need to know the path to your template directly. Luckily, WordPress provides easy access to that using the bloginfo(’stylesheet_directory’) variable. Now, to make your WordPress web site display a different logo depending on the day of the year all you need to do is edit the code from my earlier tutorial like so:

<?php
if(file_exists($_SERVER[DOCUMENT_ROOT].’/’.bloginfo(’stylesheet_directory’).’images/filename-’.date(’Y-m-d’).’.jpg’)) {
   $file = date(’Y-m-d’);
} else {
   $file = ’standard’;
}
?>

<img src=’<?php echo get_option(’home’)."/".bloginfo(’stylesheet_directory’)."/images/filename-".$file;?>.jpg’ alt=’logo for <?php date(’Y-m-d’);?>’/>

You’ll notice that I’ve introduced the

$_SERVER[DOCUMENT_ROOT]

variable which detects the server path of your WordPress installation and automatically inserts it into your query. If you’re using this technique, please let me know with a comment below.

P. S. You may want to take a look at my tutorial on caching WordPress as this process will increase server load.
