Advanced AJAX Page Loader
Hide & Show Slideshow (2 posts)

    Hi! The homepage of my website has a slideshow and right below the slideshow is the content div. When visited using the primary url, the slideshow tends to remain even when different posts and categories are loaded. Basically everything is loaded underneath the slideshow. On the other hand, when visited using an alternative url, and by "alternative" I mean a category or post/page url, the slideshow does not exist, since this function is only limited to the homepage.

    What I am trying to do, is to automatically remove the slideshow from homepage every time the visitor clicks on a link of a category, post, page or anything except homepage. And have the slideshow show up again every time the banner logo or "Home" link is visited even when the visitor has entered the website from an "alternative" url.

    This is a link to my website: http://bit.ly/RJBEZf (Sorry if I shortened it, I don't want it to be indexed)
    This is a link the theme I'm using: http://wpshower.com/themes/sight/


        $args = array(
            'meta_key' => 'sgt_slide',
            'meta_value' => 'on',
            'numberposts' => -1,
        $slides = get_posts($args);
        if ( !empty($slides) ) : $exl_posts = Array(); ?>
            <div class="slideshow"><div id="slideshow">
            <?php foreach( $slides as $post ) :
                global $exl_posts;

                delete_post_meta($post_id, $field['id'], $old);

    Words cannot describe how much I appreciate your help.
    Also the plugin is one of the most fluid and flexible ajax add-ons I've seen so far, thank you very much for sharing it.
