一次显示分类法的名称

Question

什么是最好的方法，只显示一个分类的名称一次？我使用了一个名为show_category的分类法，它有三个类别:新闻、评论和未分类。我有六篇文章:新闻三篇，评论一篇，未分类的两篇。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) tes Uncategorized (name of category in taxonomy) test 2

我正在寻找一种方法，在分类法中只使用一次这样的类别名称：

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) Tes Test 2

我的循环代码：

name;
endforeach;?>
>

Answer 1

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 '' . esc_html( $term->name ) . '';

    // And the category's posts.
    foreach ( $posts as $post ) {
        setup_postdata( $post );
        ?>
            >

PS：h3标签只是一些例子。
