How can I output WPAlchemy repeating fields meta values in my page template?

Per comments, here’s a (very rough) example of accessing repeated fields in the frontend. Note using WPAlchemy extract mode, which gives each field its own meta entry, and makes accessing them a bit simpler.

Also using actions in “functions.php” to add metabox and to output content for test purposes – obviously you’d adapt the 'init' code to your custom post type and put the 'the_content' code in your page template.

Eg, in “functions.php”:

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;
} );

Here’s the version of “download_meta.php” I used (note the metabox is addressed via $mb):

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