# new WP_Query function

 * I have a function to get related posts based on tags.
 *     ```
       function getRelatedPosts($pid) {
   
       	# for use in the loop, list 5 post titles related to first tag on current post
       	$tags = wp_get_post_tags($pid);
       	if ($tags) {
       		echo '<h3>Related Posts</h3>';
       		$first_tag = $tags[0]->term_id;
       		$args=array(
       			'tag__in' => array($first_tag),
       			'post__not_in' => array($post->ID),
       			'showposts'=>5,
       			'caller_get_posts'=>1
       		);
       		$my_query = new WP_Query($args);
       		if( $my_query->have_posts() ) {
       			while ($my_query->have_posts()) : $my_query->the_post(); ?>
       				<p><a href="<?php the_permalink() ?>" rel="bookmark"
       					title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p><?php
       			endwhile;
       		}
       	}
       	else print '<p>No related posts</p>';
       }
       ```
   
 * In single.php I am calling it.
 *     ```
       <p class="tags"><?php the_tags('<strong>Tagged:</strong> ', ', ', ''); ?></p>
       					<div id="related_posts"><?php getRelatedPosts($post->ID); ?></div>
       					<?php comments_template(); ?>
       ```
   
 * It works great, but then the comments template thinks the current post is whatever
   the last result returned from getRelatedPosts() is, rather than the actual post.
   Anything after it actually.
 * Any ideas?

 * Can anyone help me figure this out? I’m assuming a global value is being changed
   somewhere, so that comments_template() is getting the last value of the loop 
   inside the previous function.
 * Is it the new WP_Query() changing the values?
    Is it the $my_query->the_post()
   setting a global value?

 * The answer was to add this at the end of the code.
 * wp_reset_query();
