I'm asking for some grace on this question - I lack sufficient knowledge of both WP and PHP to be more specific ... so here goes:
I'd like to associate some "meta" information about my website into the content; for example a tree (e.g. Maple), so that I can use a PHP tag (and/or shortcode) to say something like
<? echo $tree ?> and get a value printed out. The reason for this is because I'm planning to set up multiple sites using MU with a different focus and some of the content will be dynamic and some manual.
What is the recommended way in WordPress to do something like this? Is this something I can define in
functions.php and then grab at my leisure?
PS - is this possibly a custom field thing? I may want this content to appear anywhere (header, sidebar, footer, in page content [etc.])
