I am not familiar with jquery or ajax, but i do know it is whats needed to perform the action I want. I have created a wordpress plugin that updates a database table based on the users click. Right now it refreshes the page to return the results, but I want to stop the page refresh and return data via ajax I believe.
If anyone is interested in helping me figure this out I would be very appreciative or even willing to pay.
Thanks!
Here is the plugin code:
function BoardLikeItGetDelim($postid)
{
global $wp_rewrite;
if($wp_rewrite->using_permalinks())
{
if(isset($_GET['mbpost']))
return "?mbpost=".$postid."&";
return "?";
}
else
{
if(isset($_GET['mbpost']))
return "&mbpost=".$postid."&";
return "&";
}
}
function AddBoardLikeItButton($postid)
{
global $user_ID;
if(isset($_GET['board-like-it-action']) && $_GET['board-like-it-action'] == "like" && $_GET['bpid'] == $postid)
BoardLikeItLike($user_ID, $_GET['bpid']);
if(isset($_GET['board-like-it-action']) && $_GET['board-like-it-action'] == "unlike" && $_GET['bpid'] == $postid)
BoardLikeItUnLike($user_ID, $_GET['bpid']);
$num_likes = BoardLikeItGetNumLikes($postid);
if(!BoardLikeItIsLiked($user_ID, $postid))
echo "<HREF LINK='".BoardLikeItGetDelim($postid)."board-like-it-action=like&bpid=".$postid."#mngl-board-post-message-".$postid."'>Like</a> ".$num_likes."" . "<br/>";
else
