我为这件事紧张了一段时间。我已经知道如何使用自定义分类法在循环中调用页面。我还了解了如何在循环中调用父页的子页。然而，我想做的是调用子页面，然后过滤掉属于自定义分类法的子页面，以便只显示这些子页面。
提前感谢您的帮助，
我可以提供更多需要的信息，
子页面代码：
<?php
$child_pages = $wpdb->get_results(
"SELECT * FROM $wpdb->posts WHERE post_parent = $post->ID AND post_type = \'page\' ORDER BY menu_order"
);
if ( $child_pages ) :
foreach ( $child_pages as $pageChild ) :
setup_postdata( $pageChild );
?>
<div class="comparison-post-block">
<div class="wrapper">
<div class="top-5-image">
<?php echo get_the_post_thumbnail( $pageChild->ID, \'thumbnail\' ) ?>
</div>
</div>
<div class="comparison-top5-text">
<div class="wrapper">
<div class="top-5-title">
<p class="comparisontitle">
<a class="comparisontitle" href="<?php echo get_permalink( $pageChild->ID ) ?>" rel="bookmark" title="<?php echo $pageChild->post_title ?>">
<?php echo $pageChild->post_title ?>
</a>
</p>
</div>
</div>
<div class="wrapper">
<div class="comparison-content">
<div class="comparisonexcerpttext">
<?php echo get_the_excerpt() ?>
</div>
</div>
</div>
</div>
</div>
<?php endforeach ?>
<?php endif ?>
自定义分类代码：
<?php
if ( is_page() ) :
global $post;
$args = array(
\'tax_query\' => array(
array(
\'taxonomy\' => \'top5\',
\'field\' => \'name\',
\'terms\' => $post->post_title
),
),
);
$My_Query = new WP_Query( $args );
if ( $My_Query->have_posts() ) :
while ( $My_Query->have_posts() ) :
$My_Query->the_post();
?>
<div class="comparison-stories">
<div class="comparison-post-block">
<div class="wrapper">
<div class="top-5-image">
<?php the_post_thumbnail( \'medium\' ) ?>
</div>
</div>
<div class="comparison-top5-text">
<div class="wrapper">
<div class="top-5-title">
<p class="comparisontitle">
<a class="comparisontitle" href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<?php the_title(); ?>
</a>
</p>
</div>
</div>
<div class="wrapper">
<div class="comparison-content">
<div class="comparisonexcerpttext">
<?php the_excerpt() ?>
</div>
</div>
</div>
</div>
</div>
</div>
<?php endwhile ?>
<?php wp_reset_postdata() ?>
<?php else : ?>
<?php endif ?>
<?php endif ?>
据我所知，我已将所有代码复制到这里，
很抱歉，这是我的第一篇帖子，所以我不太确定您想要的代码是什么，所以我想结合这两段代码！
再次感谢！

您可以获取所有孩子的ID并设置post__in 税务查询的参数：
$child_ids = $wpdb->get_col(
"SELECT ID FROM $wpdb->posts WHERE post_parent = $post->ID AND post_type = \'page\' ORDER BY menu_order"
);
$args = array(
\'post__in\' => $child_ids, // Only retrieve taxonomy posts that are children of this page
\'tax_query\' => array(
array(
\'taxonomy\' => \'top5\',
\'field\' => \'name\',
\'terms\' => $post->post_title
),
),
);
或者，如果您只想要那些不是页面子级的帖子，您可以使用参数
\'post_parent__not_in\' => array( $post->ID ).
