如何在父类别页面上显示子类别内容？

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）？

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 );
这将为您提供一个post对象数组。您可以使用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。

文档：WP_Query, setup_postdata()

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>

结束

Get_the_Categories()，但不包括“未归类”的子项

在这个函数中，我需要从$categories中排除任何属于“未分类”的子类的类别。function get_cats(){ $post_cats= array(); $categories = get_the_category(); foreach($categories as $cat){ array_push($post_cats, $cat->cat_ID); } return $pos
