Get the most popular tags in last 7 days

Hi everyone!

On my site I want to get the most popular tags in the last 7 days. I have found a code for this, but it doesn’t seem to work (https://wordpress.stackexchange.com/questions/48557/display-list-of-most-used-tags-in-the-last-30-days)

My source code:

<?php
			$wpdb->show_errors();
            global $wpdb;
            $term_ids = $wpdb->get_col("
                SELECT term_id FROM $wpdb->term_taxonomy
                INNER JOIN $wpdb->term_relationships ON $wpdb->term_taxonomy.term_taxonomy_id=$wpdb->term_relationships.term_taxonomy_id
                INNER JOIN $wpdb->posts ON $wpdb->posts.ID = $wpdb->term_relationships.object_id
                WHERE NOT term_id = '7302' AND DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= $wpdb->posts.post_date");

            if(count($term_ids) > 0){

              $tags = get_tags(array(
                'orderby' => 'count',
                'order'   => 'DESC',
                'number'  => 5,
                'include' => $term_ids,
              ));
				foreach ( (array) $tags as $tag ) {
					echo '<li class="trending-link"><a href="' . get_tag_link ($tag->term_id) . '" title="'.$tag->name.'" rel="tag" class="trending-topic">' . ucfirst($tag->name) . '</a></li>';
				}
            } else {
				echo "Der opstod en fejl. Vi beklager.";
			}
            ?>

As you can see the part “INTERVAL 7 DAY” should get the most popular tags in the last week, but it won’t work. The rest of the code is working just fine – this is the last thing I need to get working, till I can launch the site :/

Thanks.
