Prepend and Append Text to WordPress Titles

I was thinking about little ways to improve my blog and one small enhancement I wanted to make was adding more information to post titles when they show up in RSS feeds.  Something about notifying the user via title outside of the site itself seemed like a good idea.  For example, some posts are just small "quick tips", and more readers may take the time to peruse it quickly because they know it won't take too long.  Here's how I accomplished that feat with WordPress.

The PHP

The first step is creating a function, which is provided the post title and ID, that does a category check and prepends text accordingly:

function show_as_tip_in_feed($title, $id) {
	if(is_feed() && in_category('tips', $id)) {
		$title = 'Quick Tip: '.$title;
	}
	return $title;
}

Once the function is there, the add_filter hook enables the original function:

if(function_exists('add_filter')) {
	add_filter('the_title', 'show_as_tip_in_feed', 10, 2);
}

Of course you don't need to do the category check or RSS feed check -- you can append or prepend text to any and every title, and much like other WordPress functionalities, the API easily allows developers to do so.  Win!
