[wp-hackers] Loop Within A Loop

[Devin Dixon]

Hey everyone,
I am having a problem where I need to call a loop within a loop.The
code looks somethign like this

 if ( have_posts() ) while ( have_posts() ) : the_post();

       while ( $loop->have_posts() ) : $loop->the_post();

           $wp_query= new WP_Query( array( 'post_type' =>
"$post_type", 'posts_per_page' => $post_per_page , 'post_parent' =>
                $parent_post , 'author' => "$author" ) );

 while ($wp_query->have_posts()) : $wp_query->the_post();

?>

<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent
Link to <?php the_title_attribute(); ?>"><?php        the_title();
?></a>

<?php

       endwhile;

        endwhile;

endif;

The problem is, the class WP_QUERY automatically makes everything
global. Is there a way where I can call the WP_QUERY object and
retrieve it values without it affecting the other loop?
