如何在我的页面模板中输出WPAlChemy重复字段的元值？

我有一个自定义的帖子类型Downloads，它包含一些自定义的元框，包括一个重复字段。我可以在页面模板中输出所有字段的值，但无法在页面模板中输出重复字段的值。

在my downloads\\u meta中。php，我有以下内容：

<div class="my_meta_control">
  <label>Includes:</label>
  <?php $metabox->the_field(\'cb_second_includes\'); ?>
  <p><input type="checkbox" class="second-includes-check" name="<?php $metabox->the_name(); ?>" value="1"<?php $metabox->the_checkbox_state(\'1\'); ?>/><span>Different bullet points for previous version?</span></p>
  <div class="clearfix">
    <?php while($metabox->have_fields_and_multi(\'docs\')): ?>
    <?php $metabox->the_group_open(); ?>
      <?php $metabox->the_field(\'li-text\'); ?>
      <?php $wpalchemy_media_access->setGroupName(\'li-n\'. $mb->get_the_index())->setInsertButtonLabel(\'Insert\'); ?>
      <div class="col includes">
        <?php echo $wpalchemy_media_access->getField(array(\'name\' => $metabox->get_the_name(), \'value\' => $metabox->get_the_value())); ?>
        <a href="#" class="dodelete button" style="float:right;">-</a>
      </div>
    <?php $metabox->the_group_close(); ?>
    <?php endwhile; ?>
  </div>
  <p style="margin-bottom:0; padding-top:0;"><a href="#" class="docopy-docs button">+</a></p>
</div>

在我的页面模板中，我有：

<?php
  $args = array(
    // \'posts_per_page\' => 4,
    \'post_type\' => array(\'downloads\'),
    \'post_status\'     => \'publish\',
    \'orderby\' => \'menu_order\',
    \'order\' => \'ASC\'
  );

  $temp = $wp_query;
  global $wp_query;
  global $post;
  $wp_query= null;

  $wp_query = new WP_Query($args);
?>

<?php
  if($wp_query->have_posts()) :
  while ($wp_query->have_posts()) : $wp_query->the_post();
?>

  <?php
    global $downloads_meta;
  ?>

  <ul>
    <?php while($downloads_meta->have_fields(\'docs\')): ?>
      <li><?php echo $downloads_meta->get_the_value(\'li-text\'); ?></li>
    <?php endwhile; ?>
  </ul>

<?php
  endwhile;
  endif;
?>

通过上面的代码，我可以为第一个自定义post类型输出值，但第二个类型不会为重复字段输出任何值。如果能了解我可能做错了什么，我将不胜感激。

define( \'METABOX_ID\', \'my_meta_\' ); add_action( \'init\', function () { if ( is_admin() ) { if ( ! class_exists( \'WPAlchemy_MetaBox\' ) ) { require_once \'wpalchemy/MetaBox.php\'; // Assuming subdirectory of current theme directory. require_once \'wpalchemy/MediaAccess.php\'; // Assuming subdirectory of current theme directory. } global $wpalchemy_media_access; $wpalchemy_media_access = new WPAlchemy_MediaAccess(); $download_meta = new WPAlchemy_MetaBox( array( \'id\' => METABOX_ID, \'types\' => array( \'post\' ), // array( \'downloads\' ) \'template\' => get_stylesheet_directory() . \'/download_meta.php\', \'priority\' => \'default\', \'mode\' => WPALCHEMY_MODE_EXTRACT, \'prefix\' => METABOX_ID, ) ); } } ); // Just for testing - should be in the custom post type template. add_action( \'the_content\', function ( $content ) { if ( is_single() ) { $post_id = get_the_ID(); // Access single-valued (non-array) meta. $ul_class = \'docs\'; if ( $cb_second_includes = get_post_meta( $post_id, METABOX_ID . \'cb_second_includes\', true ) ) { $ul_class = \'docs_second_includes\'; } // Access array-valued meta. if ( $docs = get_post_meta( $post_id, METABOX_ID . \'docs\', true ) ) { ob_start(); ?> <ul class="<?php echo $ul_class; ?>"> <?php foreach ( $docs as $doc ) : ?> <li><?php echo $doc[\'li-text\']; ?></li> <?php endforeach; ?> </ul> <?php $content = $content . ob_get_clean(); } } return $content; } );

仅为主页显示Metabox

我将尝试使用设置字段将metabox添加到主页，但出现问题，请帮助我。删除时，metabox不会显示在页面编辑器中if statement 它显示在所有页面上。add_action(\'add_meta_boxes\', \'metabox_homepage_videos\'); function metabox_homepage_videos($post) { if (is_front_page()): add_meta_box(\'metabox
