Question

我需要从类别的子类别中获取最新的5个帖子。我该怎么做？

//编辑所以我让它为每个子类别的固定大量帖子工作：

<?php $descendants = get_categories(array('child_of' => 3)); ?> 
<?php $cnt=1;
foreach ($descendants as $child) { ?>
<?php $catPosts = new WP_Query();
    $catPosts -> query("showposts=3&cat=$child->term_id");
 ?>
<ul class="postPreviews">
<?php while ($catPosts->have_posts()) : $catPosts->the_post(); ?>
<li><a href="<?php the_permalink() ?>">
    <div class="descOverlay">
        <img src="<?php the_field('teaserimage'); ?>" />
        <div class="overlayTitle">
            <div class="imgwrap"><img src="<?php echo get_template_directory_uri(); ?>/opaq.png"></div>
            <span><?php the_title(); ?></span></div>
        </div>
    </a></li>
<?php endwhile; 
}?>

我会使用get_categories（）遍历所有子类别并将其ID添加到数组中。然后，您可以将该数组用于新的WP_Query的category__in'参数。

<?php
    $categories = get_categories( array(
        'child_of'=>'your_category_id'
    ) );

    $subcategories = array();

    foreach ( $categories as $category ) {
        $subcategories[] = $category->cat_ID;
    }
?>

<?php
    $new_loop = new WP_Query( array(
    'post_type' => 'post',
    'category__in' => $subcategories,
    'posts_per_page' => 5
    ) );
?>

<?php if ( $new_loop->have_posts() ) : while ( $new_loop->have_posts() ) : $new_loop->the_post(); ?>

    // put your inside the loop code here

<?php endwhile; else: ?>
    No posts found
<?php endif; ?>
<?php wp_reset_query(); ?>

使用Wordpress中的循环从类别的子类别中获取最新的5个帖子
