我有一个复杂的帖子查询，但我无法让页面导航正常工作，已经尝试了几个小时，但没有成功，我错过了什么？

$paged = (get_query_var(\'paged\')) ? get_query_var(\'paged\') : 1;
$args = array(
    \'post_type\' => array(\'recipe\',\'post\'),
    \'posts_per_page\'  => 30,
    \'paged\' => $paged,
    \'tax_query\' => array(
          \'relation\' => \'OR\',
       array(
         \'taxonomy\' => \'condition\',
         \'terms\' => $arrArea1,
         \'field\' => \'slug\'
       ),      
       array(
         \'taxonomy\' => \'diet_type\',
         \'terms\' => \'High Fiber\',
         \'field\' => \'slug\'
       ),          
   )
);
$query = new WP_Query( $args );
?>  
<div class="postCont">   
    <?php if ( $query->have_posts() ) : ?>
        <h2>What\'s Fresh</h2>
        <?php while ( $query->have_posts() ) : $query->the_post(); ?>
            <?php get_template_part( \'content\', \'profile-subscriber\' ); ?>
        <?php endwhile; ?>
        <div class="navigation">
            <?php posts_nav_link(); ?>
        </div>
    <?php else:  ?>
        <p><?php _e( \'Sorry, no posts matched your criteria.\' ); ?></p>
    <?php endif; ?>
    <?php wp_reset_postdata(); ?>              
</div>    

我需要弄清楚这一点，以便我可以做一些ajax加载更多的后期操作，如有任何帮助，将不胜感激
