你的问题是你正在使用the_ID() 为每个分类术语指定ID，但是the_ID() 不在foreach循环中输出当前项的ID，而是获取当前项的ID。

由于您没有在自定义查询中重置postdata，因此这将是上一学期最后一篇文章的ID。

要为每个手风琴指定唯一的ID，请将术语的ID与$term->term_id:

<?php
/*
 * Loop through Categories and Display Posts within
 */
$post_type = \'faqs\';

// Get all the taxonomies for this post type
$taxonomies = get_object_taxonomies( array( \'post_type\' => $post_type ) );

foreach( $taxonomies as $taxonomy ) :
    // Gets every "category" (term) in this taxonomy to get the respective posts
    $terms = get_terms( $taxonomy );

    foreach( $terms as $term ) : 
        $args = array(
            \'post_type\'      => $post_type,
            \'posts_per_page\' => -1,  //show all posts
            \'tax_query\'      => array(
                array(
                    \'taxonomy\' => $taxonomy,
                    \'field\'    => \'slug\',
                    \'terms\'    => $term->slug,
                )
            )

        );
        ?>

        <h2 style="margin-bottom: 20px;">
            <a data-toggle="collapse" data-parent="#accordion" href="#collapse-<?php echo $term->term_id; ?>" aria-expanded="true" aria-controls="collapse-<?php echo $term->term_id ?>">
                <?php echo $term->name; ?> +
            </a>
        </h2>

        <div id="collapse-<?php echo $term->term_id; ?>" class="panel-collapse collapse <?php if( $c == 1 ) echo \'in\'; ?>" role="tabpanel" aria-labelledby="heading-<?php echo $term->term_id; ?>">

            <?php $localfaqs = new WP_Query( $args );?>

            <?php if ( $localfaqs->have_posts() ) : while ( $localfaqs->have_posts() ) : $localfaqs->the_post(); $c++; ?>
                <div class="row">    
                    <?php 
                    $faqs = get_field(\'local\');

                    if ( $faqs ) : foreach ( $faqs as $p ): // variable must NOT be called $post (IMPORTANT) 
                        ?>

                        <div class="col-md-half faq-circle">
                            <div class="celeb-circle-faq">
                                <a href="<?php echo get_permalink( $p->ID ); ?>"><?php echo get_the_post_thumbnail( $p->ID ); ?></a>
                            </div>
                        </div>

                    <?php endforeach; endif; ?>

                    <div class="col-md-10 faq-link">
                        <a href="<?php the_permalink();?>">
                            <?php the_title();?>
                        </a>
                    </div>
                </div>
            <?php endwhile; endif; wp_reset_postdata(); ?>
        </div>
    <?php
    endforeach;
endforeach;

我还补充道wp_reset_postdata(); 在自定义查询循环之后，这样循环之后的任何代码都不会引用错误的帖子。
