带有 $posts 和 $terms 的 foreach

Question

我正在使用 ACF relationship field on a Wordpress site so that the admin user can easily determine which posts are visible on that page. I have a custom taxonomy where I need to be able to get_the_terms and print the term for each post. This is normaly achieved with an foreach as mentioned in the codex。

但是我使用 foreach 来获取 $posts 所以我不确定如何使用它来打印我的 H3 中的术语名称和主 [=] 中的术语 slug 14=]

代码如下：

<?php
$posts = get_field('team_members',12);
$terms = get_the_terms( $post->ID , 'position' );
if( $posts ): ?>
    <?php foreach( $posts as $post): // variable must be called $post (IMPORTANT) 
    setup_postdata($post); ?>
    <div class="col-4 col <?php echo $term->slug;?>">
        <article id="post-<?php the_ID(); ?>" <?php post_class('team-item'); ?>>
            <hgroup>
                <?php the_title( sprintf( '<h2 class="alt-heading-4">', esc_url( get_permalink() ) ), '</h2>' ); ?>
                <h3><?php echo $term->name;?></h3>
            </hgroup>

            <div class="team-entry-content">
                <?php the_content();?>
            </div><!-- .entry-content -->
            <div id="team-shadow"></div>
        </article><!-- #post-## -->
    </div>
     <?php endforeach; ?>
    <?php wp_reset_postdata();?>
<?php endif; ?>

由于条款与您的 post 相关联，因此您必须放置 :

$terms = get_the_terms( $post->ID , 'position' );

在 foreach 循环内，在循环外它根本不起作用，因为 $post->ID 会出错：

trying to get the property of non object

所以解决方案是采用 $terms = get_the_terms( $post->ID , 'position' ); 并将其添加到 foreach 循环中：

<?php
$posts = get_field('team_members',12);
if( $posts ): ?>
    <?php foreach( $posts as $post): // variable must be called $post (IMPORTANT) 
    setup_postdata($post);
       $terms = get_the_terms( $post->ID , 'position' ); ?>
    <div class="col-4 col <?php echo $term->slug;?>">
        <article id="post-<?php the_ID(); ?>" <?php post_class('team-item'); ?>>
            <hgroup>
                <?php the_title( sprintf( '<h2 class="alt-heading-4">', esc_url( get_permalink() ) ), '</h2>' ); ?>
              <?php foreach($terms as $term) {?>
                <h3><?php echo $term->name;?></h3>
              <?php } ?>
            </hgroup>

            <div class="team-entry-content">
                <?php the_content();?>
            </div><!-- .entry-content -->
            <div id="team-shadow"></div>
        </article><!-- #post-## -->
    </div>
     <?php endforeach; ?>
    <?php wp_reset_postdata();?>
<?php endif; ?>
