I’d like to use the tags I have made for posts as their keywords in the Meta field. It makes good SEO, even if keyword tags are going out of style, it can’t hurt. This is what I have so far:

[php]
< ?php if (function_exists('UTW_ShowCurrentTagSet')) {
// Check if UTW exists, if so then do this: ?>
<meta name=”keywords” content=”< ?php echo UTW_ShowCurrentTagSet('tagsettextonly'); ?>“>
< ?php } ?>
[/php]

I place this little tidbit of code within the header PHP within the following if statement so that it only shows up on pages or posts:

I need a wordpress plugin or method that allows me to show code in posts such that readers can cut and paste it out of the page and into their own application and have it work. Any ideas?
