只显示一次分类法名称的最佳方式是什么？我使用了一种叫做show_category 它有三类：新闻、评论和未分类。我有六个帖子：三个在新闻中，一个在评论中，两个在未分类中。它们显示如下：
News (name of category in taxonomy)
News item 1
News (name of category in taxonomy)
News item 2
News (name of category in taxonomy)
News item 3
Reviews (name of category in taxonomy)
Review item
Uncategorized (name of category in taxonomy)

我正在寻找一种方法，在分类法中只使用一次类别名称，如下所示：
News (name of category in taxonomy)
News item 1
News item 2
News item 3
Reviews (name of category in taxonomy)
Review item
Uncategorized (name of category in taxonomy)

我的循环代码：
<?php $postcount=0; while ( have_posts() ) : the_post();
$terms = wp_get_post_terms( get_the_ID(), \'show_category\');
foreach ($terms as $t):
echo $t->name;
endforeach;?>
<div id="<?php the_ID(); ?>" <?php post_class(); ?>>
<?php the_title();?>
</div>
<?php endwhile; ?>

不是最好的，但对我来说效果很好：（你可以用这个代替问题中的内容）
$postcount = 0;
//global $wp_query; // Uncomment if necessary.
// Group the posts by category.
$groups = [];
foreach ( $wp_query->posts as $i => $p ) {
$terms = wp_get_post_terms( $p->ID, \'show_category\' );
foreach ( $terms as $t ) {
if ( ! isset( $groups[ $t->term_id ] ) ) {
$groups[ $t->term_id ] = [];
}
$groups[ $t->term_id ][] =& $wp_query->posts[ $i ];
}
}
// And display the posts under their own category. Note though, that a post may
// appear twice if it\'s assigned to multiple categories.
global $post;
foreach ( $groups as $term_id => $posts ) {
$term = get_term( $term_id );
// Display the term/category name.
echo \'<h3>\' . esc_html( $term->name ) . \'</h3>\';
// And the category\'s posts.
foreach ( $posts as $post ) {
setup_postdata( $post );
?>
<div id="<?php the_ID(); ?>" <?php post_class(); ?>>
<?php the_title(); ?>
</div>
<?php
}
}
wp_reset_postdata();
