我有一个CPT合并CMB2. 我循环浏览每个类别，并显示该类别中的每个帖子。我的问题是，每个类别中的第一篇文章不会显示两个元数据库中的某些信息：标签名称（$标签）和发布日期（$日期），但每个类别中的其他文章都会显示这些信息。到目前为止，我有大约8个类别，这在所有类别中都会发生。

当我var_dump($label);, 显示每个类别的第一个帖子string(0) "", 尽管在管理方面有一些东西。所有其他帖子都可以。有什么想法吗？

以下是元数据库：

add_action( \'cmb2_init\', \'awc_discog_details\' );
function awc_discog_details() {

$prefix = \'_awc_\';

$cmb = new_cmb2_box( array(
    \'id\'           => $prefix . \'details_metabox\',
    \'title\'        => __( \'Label / Release Date\', \'cmb2\' ),
    \'object_types\' => array( \'awc_discography\' ),
    \'context\'      => \'normal\',
    \'priority\'     => \'high\',
) );

$cmb->add_field( array(
    \'name\' => __( \'Label Name\', \'cmb2\' ),
    \'id\' => $prefix . \'label_name\',
    \'type\' => \'text_medium\',
) );

$cmb->add_field( array(
    \'name\' => __( \'Release Date\', \'cmb2\' ),
    \'id\' => $prefix . \'release_date\',
    \'type\' => \'text_date\',
) );

}

<?php
$tax_terms = get_terms( \'category\', array( \'orderby\' => \'id\' ) );

foreach ($tax_terms as $tax_term) {

    $args = array(
        \'cat\'               => $tax_term->term_id,
        \'post_type\'         => \'awc_discography\',
        \'posts_per_page\'    => \'-1\',
        \'orderby\'           => \'ID\',
    );

    $query = new WP_Query( $args );
    $nice_class = strtolower($tax_term->name);
    $nice_class = preg_replace("/[\\s_]/", "-", $nice_class);

if ( $query->have_posts() ) { ?>

<section class="<?php echo $nice_class; ?> listing">
    <h3><?php echo $tax_term->name; ?>:</h3>

    <?php while ( $query->have_posts() ) {

        $label = get_post_meta( get_the_ID(), \'_awc_label_name\', true ); 
        $date = get_post_meta( get_the_ID(), \'_awc_release_date\', true ); 

        $query->the_post();
    ?>

                    </a>
                </div>
            <?php } ?>

              the_content();
