向查询的第一个帖子添加类

如何将is active类添加到第一个<li> 是否由查询生成？谢谢你，我很感激。

<?php
    $_terms = get_terms( array(\'claim-accordion-type\') );

    foreach ($_terms as $term) :

        $term_slug = $term->slug;
        $_posts = new WP_Query( array(
                    \'post_type\'         => \'claims_accordion\',
                    \'posts_per_page\'    => -1,
                    \'tax_query\' => array(
                        array(
                            \'taxonomy\' => \'claim-accordion-type\',
                            \'field\'    => \'slug\',
                            \'terms\'    => $term_slug,
                        ),
                    ),
                ));

        if( $_posts->have_posts() ) :

 echo\'<li class="accordion-item " data-accordion-item>\';

        echo\'<a href="#" class="accordion-title">\';
            echo \'\'. $term->name .\'\';

        echo\'</a>\';






            while ( $_posts->have_posts() ) : $_posts->the_post();





        ?>

    <div class="accordion-content" data-tab-content>


      <a data-open="exampleModal1">
        <h4><?php the_title(); ?></h4></a>


    </div>

    <?php
        endwhile;


   echo \'</li>\';
        endif;
        wp_reset_postdata();




    endforeach;
    ?>

</ul>

<?php $_terms = get_terms( array(\'claim-accordion-type\') ); $i = 0; foreach ($_terms as $term) : $term_slug = $term->slug; $_posts = new WP_Query( array( \'post_type\' => \'claims_accordion\', \'posts_per_page\' => -1, \'tax_query\' => array( array( \'taxonomy\' => \'claim-accordion-type\', \'field\' => \'slug\', \'terms\' => $term_slug, ), ), )); if( $_posts->have_posts() ) : $i++; if ( $i == 1 ) { $class = \'is-active\'; } else { $class = null; } echo\'<li class="accordion-item \' . $class . \'" data-accordion-item>\'; echo\'<a href="#" class="accordion-title">\'; echo \'\'. $term->name .\'\'; echo\'</a>\'; while ( $_posts->have_posts() ) : $_posts->the_post(); ?> <div class="accordion-content" data-tab-content> <a data-open="exampleModal1"> <h4><?php the_title(); ?></h4></a> </div> <div class="reveal" id="exampleModal1" data-reveal> <?php the_content(); ?> <button class="close-button" data-close aria-label="Close modal" type="button"> <span aria-hidden="true">×</span> </button> </div> <?php endwhile; echo \'</li>\'; endif; wp_reset_postdata(); endforeach; ?> </ul> ?>

GET_THE_TERMS与wp_GET_POST_TERMS中的奇怪结果

我正在尝试制作一个面包屑函数，但有一个小问题。。。使用时：$categories = get_the_terms( $post->ID, \'product_cat\' ); 我得到了一个循环中使用的类别数组，等等。唯一的问题是它是按字母顺序排列的。（我希望它按层次顺序排列。）经过一番挖掘，我发现了一种替代方法，即使用wp\\u get\\u post\\u terms（），但我肯定遗漏了一些东西，因为当我使用此方法时：$categories = wp_get_post_terms( $p
