不显示下一个和上一个(在本例中为分页)

我正在为我的公文包使用自定义页面模板。代码正在调用每页的正确帖子数，但由于某些原因，分页链接不会显示：-S

我的查询

<?php 
    $loop = new WP_Query(array(\'post_type\' => \'portfolio\', \'posts_per_page\' => 2)); 
?>
<?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
<?php   
    $custom = get_post_custom($post->ID);
    $screenshot_url = $custom["screenshot_url"][0];
    $website_url = $custom["website_url"][0];
?>

整个标记

<?php
/*
Template Name: Portfolio
*/
?>

<?php get_header(); ?>

<div id="full_container">
<div id="portfolio_content">
<div id="portfolio_wrap">
<div id="content">

    <?php 
        $loop = new WP_Query(array(\'post_type\' => \'portfolio\', \'posts_per_page\' => 2)); 
    ?>
    <?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
    <?php   
        $custom = get_post_custom($post->ID);
        $screenshot_url = $custom["screenshot_url"][0];
        $website_url = $custom["website_url"][0];
    ?>


<a href="<?php the_permalink() ?>">

<span class="img">
<?php if ( has_post_thumbnail() ) { the_post_thumbnail( \'thmb-portfolio\' ); } ?>

<span class="under">
<!-- Excerpt title -->
<span class="title"><?php the_title(); ?></span>

<!-- Excerpt description -->
<span class="desc">
    <?php my_excerpt(\'short\'); ?>
</span>
</span>
</span>
</a>


        <?php endwhile; ?>  

<!-- Next/Previous Posts -->
<?php if (function_exists("pagination")) {
    pagination($additional_loop->max_num_pages);
} ?>

</div>
</div>
</div>
</div>
</div>

<?php get_footer(); ?>
