是否将分类术语作为类名追加到标记中？

我已经为“person”定义了一个自定义的post类型，我想根据与团队名称相对应的分类法将类名附加到输出标记中。例如，如果一个人是“创意”和“互动”团队的一部分，我想输出以下内容：

<div class="person creative interactive">Jane</div>

我发现this thread 在论坛上，但在我的例子中，我需要在echo 语句，因为输出在functions.php 文件

这是我迄今为止提出的一个简化版本，基于上述线程和this Stack Overflow thread:

function display_all_people() {
    // set up arguments for new post query
    $args = array(
        \'post_type\' => \'people\',
        \'order\' => \'ASC\',
        \'orderby\'    => \'meta_value\',
        \'meta_key\'   => \'last_name\'
        );

    $peoplePosts = new WP_Query( $args );
    if ( $peoplePosts->have_posts() ) {
        echo \'<div class="people-listing">\';
        while ( $peoplePosts->have_posts() ) {
            $peoplePosts->the_post();
            $terms = get_the_terms( $post->ID, \'teams\' );

            foreach ($terms as $term) {
                echo \'<div class="person\' . implode(\'\', $term->slug) . \'">\';
            }

            echo \'<div>More markup for each person listing</div>\';
            echo \'</div>\';
        } 
        echo \'</div>\';
    } else {
        return \'<p>Nothing Here.</p>\';
    }
    wp_reset_postdata();
}

因此，我试图使用implode() 连接数组的值（即“团队”分类名称），但它似乎不起作用（PHP正在抛出错误）你知道我如何以这种方式成功地将分类法附加为类名吗？感谢您的帮助。

$terms = get_the_terms( $post->ID, \'teams\' ); // create a collection with your default item $classes = array(\'person\'); foreach ($terms as $term) { // add items $classes[] = $term->slug; } // output all the classes together with a space to separate them. echo \'<div class="\' . implode(\' \', $classes) . \'">\'; echo \'<div>More markup for each person listing</div>\';

$terms = get_the_terms( $post->ID, \'teams\' ); // create a collection with your default item $classes = array( \'person\' ); if ( $terms && ! is_wp_error( $terms ) ) { foreach ( $terms as $term ) { $classes[] = $term->slug; // add items } } // remove any specific classes here $classes = array_diff( $classes, array( \'creative-services\' ) ); // output all the classes together with a space to separate them. echo \'<div class="\' . implode( \' \', $classes ) . \'">\'; echo \'<div>More markup for each person listing</div>\';
