Looking through the Blogsome/WPµ source, I came across a Smarty function {globalvar}. “Righto,” I thought, “I’ll google that, and see what comes up.” My template file was the first thing that did. Okay, what this function does is take a Smarty variable, and make it global in the PHP scope. Used in my template, and most Blogsome ones, it sets the variable $comment to be a global one. I haven’t come up with another good use for it, but it’s nice to know.
