我的主页上有多个循环。我试图在每个循环中显示自定义字段。但其中一些没有出现。有什么想法吗，为什么？代码如下：

//check for Featured Events here
   $featured = new WP_Query (array(
   \'category_name\' => \'Featured Events\',
   \'posts_per_page\' => 2) 
   ); 
    if ($featured -> have_posts()) { 
    while ($featured->  have_posts()) : $featured -> the_post(); ?>

<h2 class="featured"> <?php the_title(); ?> </h2>  
      <h3 class="featured">
    <?php echo get_post_meta($post->ID, \'Date\', true); ?>  </h3>

<h4 class="featured">
    <?php echo get_post_meta($post->ID, \'Start Time\', true); ?>
      <?php if ( get_post_meta($post->ID, \'End Time\', true) != "") { ; ?>
     &nbsp;-&nbsp; 
    <?php echo get_post_meta($post->ID, \'End Time\', true); }?> </h4>

<!--only print sponsor if value there  -->
 <?php if ( get_post_meta($post->ID, \'Sponsor\', true) != "") { ; ?>

<h5 class="featured">

<?php echo get_post_meta($post->ID, \'Sponsor\', true); ?></h5>
<?php }; ?>
 <?php if ( get_post_meta($post->ID, \'Cost\', true) != "") { ; ?>

 <p class="cost"> 

<?php echo \'Cost: \'. get_post_meta($post->ID, \'Cost\', true); ?> </p> <?php }; 
    if ( get_post_meta($post->ID, \'Location\', true) != "") { ; ?>

 <h6 class="featured">

<?php echo \'Location: \'. get_post_meta($post->ID, \'Location\', true); ?>
    </h6>

 <?php }; 
    global $more;
$more = 0; 
  the_content(\'Read more please\'); 
  if ( get_post_meta($post->ID, \'link\', true) != "") { ; ?>

 <p> <a href="
 <?php echo get_post_meta($post->ID, \'link\', true); ?> " 

> Click here for more information </a> </p>

 <?php } endwhile; 
     } 
     wp_reset_query(); ?> 

           </div> <!-- content_inner -->
         </div> <!-- content -->
       </div>   <!-- end 2 column wrap div   -->

           <div  id="lftcol">
      <div id="lcol_inner">

<?php 
   $ann_query = new WP_Query (array(
   \'category_name\' => \'announcement\',
   \'orderby\'=> \'modified\',
   \'posts_per_page\' => 5) );

    if ($ann_query -> have_posts()) { 
    while ($ann_query->  have_posts()) : $ann_query -> the_post();

    if( $post->ID == $do_not_duplicate ) continue; //This is the Magic Line
// echo \'NON urgent announcement should follow \'; ?>

 <h2 class="featured"> <?php the_title(); ?> </h2>

    <?php 
//The code must be inserted ahead of the call the_content, but AFTER the_post()
global $more;
$more = 0; ?>

<h3 class="featured">

<?php echo get_post_meta($post->ID, \'Date\', true); ?>  

</h3>

 <h4 class="featured"> 

    <?php echo get_post_meta($post->ID, \'Start Time\', true); ?>

    <?php } 
            endwhile;   }
            wp_reset_query(); ?>

        </div>
           </div>
