notice with #rating-hover-score. I’ve got one of those ’3 out of 5′ things that change as you hover. Javascript for that…

jQuery(document).ready(function($){
$(‘.star-rating a’).each(function(){
var value = $(this).attr(‘rel’);
$(this).hover(function(){
$(‘#rating-hover-score’).html(value + ‘ out of 5′);
});
});

$(‘.star-rating’).mouseleave(function(){
$(‘#rating-hover-score’).html(”);
});
});

I also changed the clearSelected() function.

function clearSelected() {
$(‘.star-rating a’).removeClass(‘current-rating’);
}

You’ll also need to change the rateClick javascript function but it should be obvious what you need to do

Lastly you’ll need to edit the widths in the css. Also have a half star graphic.

span.star { display: block; height: 18px; width: 18px; background-image: url(images/stars.png); float: left; }
span.star_off { background-position: center top; }
span.star_on { background-position: center bottom; }
span.star_half { background-position: center center; }

As the site I worked on is unilingual, it used the qtranslate plugin. That messed up the CI routing so here is a quick fix:

public function __construct() {
global $table_prefix, $wp_embed, $wp_widget_factory, $_wp_deprecated_widgets_callbacks, $wp_locale, $wp_rewrite;
// Additional WordPress global variables
//$wpdb, $current_user, $auth_secure_cookie, $wp_roles, $wp_the_query, $wp_query, $wp, $_updated_user_settings,
//$wp_taxonomies, $wp_filter, $wp_actions, $merged_filters, $wp_current_filter, $wp_registered_sidebars,
//$wp_registered_widgets, $wp_registered_widget_controls, $wp_registered_widget_updates, $_wp_deprecated_widgets_callbacks,
//$posts, $post, $wp_did_header, $wp_did_template_redirect, $wp_version, $id, $comment, $user_ID;

$request_uri = $_SERVER['REQUEST_URI'];

require_once ‘../wp-load.php’;

// restore the normal REQUEST_URI
$_SERVER['REQUEST_URI'] = $request_uri ;

}

Here is a function I am using in my main controller for non mobile users to launch the desktop WP version of the site.

/**
* This is a wordpress hack.
*
*/
private function loadwordpress(){

// these variables need to re re-globalized.
global $post, $q_config, $wp;
global $wp_rewrite, $wp_query, $wp_the_query;

define(‘WP_USE_THEMES’, true);

/** Loads the WordPress Environment and Template */
require(‘./wp-blog-header.php’);

}
