 * Hello,
 * I am currently working on a project that requires users to down vote and upvote
   things, an example being links in a post.
 * I have all of the voting data saved into custom fields for each post.
    Currently
   when a person down votes or upvotes something I have a Javascript function that
   makes a xmlhttprequest to a PHP script somewhere on my server.
 * The script loads wordpress functions using
    `require_once('../../../../wp-load.
   php');`
 * and I update_post_meta or do whatever I have to do.
 * I am wondering if this is the best way to go about getting this effect and what
   is the best practice for doing something like this?
 * Thanks

 * Surely, that’s not the best way to use Ajax.
 * Check this [http://codex.wordpress.org/AJAX_in_Plugins#Ajax_on_the_Viewer-Facing_Side](http://codex.wordpress.org/AJAX_in_Plugins#Ajax_on_the_Viewer-Facing_Side)
   to learn how to use ajax on front end. Though it uses plugins as examples, you
   can try it with themes.
