Jquery + PHP - AJAX onclick favorite/unfavorite

Hello DPers,

I am trying to build out a quick and dirty favorite feature for my site using Jquery and a little bit of ajax.

Similar to the one used here on this arcade site.

So far I have tried using a simple php GET request as well as a POST request, nothing seems to work.

Here is the Javascript code I have thus far:

--- JAVASCRIPT ---

$(document).ready(function() {

	favGame();

	// Favorite Link //
	function favGame() {
			
		$("a.arfavorite").click(function() {
			$.get("favorites.php", {gid: gid, ar: ar}, function() {
				alert("it all worked");
			});
			return false;
		});
	}

});

--- JAVASCRIPT ---

Code (markup):

Here is the PHP code I have thus far:

--- PHP ---

if (!isset($favorites[$game['id']])) {
	echo "<a title='Add Favorite' class='arfavorite' href='profile/favorites.php' rel='nofollow'>Add To My Favorites</a>";
} else {
	echo "<a title='Remove Favorite' class='arfavorite' href='profile/favorites.php' rel='nofollow'>Remove From My Favorites</a>";
}
