自定义分类-修改函数以获取子类别

我正在使用这两个函数，从而获得自定义分类法的顶级父类别。这些已经过测试，并按预期工作。

然而，现在我正在寻找一种方法来输出子类别而不是父类别。

function get_term_top_most_parent( $term, $taxonomy ) {
    // Start from the current term
    $parent  = get_term( $term, $taxonomy );
    // Climb up the hierarchy until we reach a term with parent = \'0\'
    while ( $parent->parent != \'0\' ) {
        $term_id = $parent->parent;
        $parent  = get_term( $term_id, $taxonomy);
    }
    return $parent;
}

function get_top_parents( $taxonomy ) {
    // get terms for current post
    $terms = wp_get_object_terms( get_the_ID(), $taxonomy );
    $top_parent_terms = array();

    foreach ( $terms as $term ) {
        //get top level parent
        $top_parent = get_term_top_most_parent( $term, $taxonomy );
        //check if you have it in your array to only add it once
        if ( !in_array( $top_parent, $top_parent_terms ) ) {
            $top_parent_terms[] = $top_parent;
        }
    }

    // build output (the HTML is up to you)
    foreach ( $top_parent_terms as $term ) {
          //Add every term
          $output = $term->slug;
    }

    return $output;
}

function cat_childs( $term_id = 0) { $children = get_terms( array( \'child_of\' => $term_id, \'taxonomy\' => \'product_cat\', \'hide_empty\' => true, \'fields\' => \'ids\', )); return ( $children ); }

$cat_args = array( \'orderby\' => \'name\', \'order\' => \'asc\', \'hide_empty\' => true); $cats = get_terms( \'product_cat\', $cat_args ); foreach ($cats as $key => $cat): if ($cat->parent == 0): ?> <a href="<?php echo get_term_link($cat) ?>" style="color:red;"><?php echo $cat->name; ?></a><?php if (cat_childs($cat->term_id)): foreach ($cats as $key => $cat2): if ($cat2->parent == $cat->term_id): ?> <a href="<?php echo get_term_link($cat2) ?>" style="margin-left:20px; color:blue;"><?php echo $cat2->name; ?></a><?php if (cat_childs($cat2->term_id)): foreach ($cats as $key => $cat3): if ($cat3->parent == $cat2->term_id): ?> <a href="<?php echo get_term_link($cat3) ?>" style="margin-left:40px; color:green;"><?php echo $cat3->name; ?></a><?php endif; endforeach; endif; endif; endforeach; endif; endif; endforeach;

Trim posts from WP-Query?

我希望在我的首页上显示一些由以下标准确定的帖子：显示当月的所有帖子（实际上是从最近帖子对应的月份开始）；但是如果这个数字少于（比如）8，那么就显示最近的8篇帖子。假设我知道每个月都不会有超过（比如）20篇文章，我会将posts\\u per\\u page设置为20，通常抓取最近的20篇文章，然后在php中进行适当的修剪（切片）。（在SQL中这样做似乎太复杂了）顺便说一句：起初我以为add_filter( \'posts_results\', ... ) 这很合适，但很难区分查询是与主循环相对应，还是与其
