我有一个WordPress网站，它有一个类别和两个子类别。
现在，如何在父类别上显示内容（子类别项目/内容）？
如何在父类别页面上显示子类别内容？

一种可能性：
<?php
$sub_cats = get_categories(\'parent=\' . get_query_var(\'cat\'));
if( $sub_cats ) :
foreach( $sub_cats as $sub_cat ) :
$sub_query = new WP_Query( array(
\'category__in\' => array( $sub_cat->term_id ),
\'posts_per_page\' => -1)
);
if ( $sub_query->have_posts() ) :
while( $sub_query->have_posts() ) : $sub_query->the_post();
//your output//
endwhile;
endif;
endforeach;
endif;
?>

$cat = get_query_var( \'cat\' );
$args = array(
\'post_status\' => \'publish\',
\'tax_query\' => array(
array(
\'taxonomy\' => \'category\', //may be categories, I never remember, try both
\'field\' => \'slug\', //may need to use ID, depends on output
\'terms\' => $cat
//children are included by default
)
)
);
$posts = new WP_Query( $args );
setup_postdata() 如果你想的话，把它输入到一个循环中。当您添加子类别时，此代码将是可扩展的，它们也将被查询。更新
<?php
$cat = get_query_var( \'cat\' );
$args = array(
\'post_status\' => \'publish\',
\'tax_query\' => array(
array(
\'taxonomy\' => \'category\', //may be categories, I never remember, try both
\'field\' => \'id\', //may need to use slug, depends on output
\'terms\' => $cat
//children are included by default
)
)
);
$my_posts = new WP_Query( $args );
?>
<?php if ( $my_posts->have_posts()) : while ( $my_posts->have_posts() ) : $my_posts->the_post(); ?>
<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<div class="entryCategory">
<a href="<?php the_permalink(); ?>" rel="bookmark"><?php the_post_thumbnail( \'thumbnail\', array( \'class\' => \'alignright\' ) ); ?></a>
</div>
