WordPress: Check if User is Logged In

John Chow had a nice tip on his site today on posting an advertising link on your site and ensuring that it’s not indexed using nofollow. You can do this with a simple redirect page that John posts the code for.

I wanted to do this a little different. In my horizontal menu above, real estate is at a premium. I do have an admin link on there if I’m logged in… but for everyone else, that’s a blank spot. I decided, why not swap the content of that bar in the event it’s a visitor and not me? With WordPress, this is pretty simple:

get_currentuserinfo() ;
global $user_level;
if ($user_level > 0) {
wp_register('>li class="menuitem">','>/li>');
} else {
echo ">li class='menuitem'>>a href="/go/tla.html" title='Advertise on this Website'>Advertise>/a>>/li>";
}
?>

I haven’t made a dime with Text Link Ads yet but I want to give it a good shot. It’s pretty inexpensive for my site… $35 per month and I get over 500 visitors a day. I look forward to serving some of these up!
