具有多个术语的自定义帖子仅返回一次

Question

我有一个自定义帖子类型 products，它的分类是 range。 我有另一个自定义帖子类型 stockist，它使用 ACF post_object 将产品与库存商相关联。

我正在尝试遍历库存商帖子，返回每个术语的标题，然后通过帖子对象返回与库存商关联的每个产品的列表。

<?php                           
$args2 = array( 'post_type' => 'stockist', 'posts_per_page' => -1 );
$stockistloop2 = new WP_Query( $args2 );
if ( $stockistloop2->have_posts() ): while ( $stockistloop2->have_posts() ): $stockistloop2->the_post();?>
<div class="col-1-1 clearfix nopad stockist-block-dropdown STORE <?php the_title();?>">
    <h2 class="stockist-title"><?php the_title();?></h2>
<?php 
$args = array( 'taxonomy' => 'range');
$categories = get_categories($args);
 if($categories): foreach($categories as $category): $url = get_category_link( $category->term_id ); ?>
    <div class="col-1-5 mobile-col-1-2">
        <h4><?php echo ($category->name) ;?></h4>
        <?php $post_objects = get_field('stocked_range'); if( $post_objects ): ?>
        <ul class="stockist-block-products clearfix">
        <?php foreach( $post_objects as $post_object): $post_terms_array = get_the_terms($post_object, 'range'); $post_term_name = $post_terms_array[0]->slug; 
            if($post_term_name == $category->slug):?>
            <li>
                <a href="<?php echo get_permalink($post_object->ID); ?>" target="_blank"><?php echo get_the_title($post_object->ID); ?></a>
            </li>
            <?php endif; endforeach; ?>
        </ul>
    <?php  endif;?>
    </div>
    <?php endforeach; endif;?>
</div>
<?php endwhile; wp_reset_postdata(); endif; ?>

这在某种程度上有效，但产品有多个术语。例如，pork sausage 可能有术语“sausages”和“bbq”，它只在 sausages 下返回一次，而不是在两个术语下都返回。

任何人都可以提供任何建议吗？

您的问题在于以下几行：

$post_term_name = $post_terms_array[0]->slug;
if($post_term_name == $category->slug):

您将循环中的每个 $category 与仅与产品关联的第一个术语进行比较。试试这个（为了我自己的清楚，我稍微编辑了格式）。

<?php                           
$args2 = array( 
    'post_type'      => 'stockist', 
    'posts_per_page' => -1 
);
$stockistloop2 = new WP_Query( $args2 );
if ( $stockistloop2->have_posts() ): while ( $stockistloop2->have_posts() ): $stockistloop2->the_post();
?>
<div class="col-1-1 clearfix nopad stockist-block-dropdown STORE <?php the_title();?>">
    <h2 class="stockist-title"><?php the_title();?></h2>
    <?php 
    $args = array( 
        'taxonomy' => 'range'
    );
    $categories = get_categories($args);
    if($categories): 
    foreach($categories as $category): 
    $url = get_category_link( $category->term_id ); 
    ?>
    <div class="col-1-5 mobile-col-1-2">
        <h4><?php echo ($category->name); ?></h4>
        <?php 
        $post_objects = get_field('stocked_range'); 
        if( $post_objects ): 
        ?>
        <ul class="stockist-block-products clearfix">
            <?php 
            foreach( $post_objects as $post_object ): 
            $post_terms_array = get_the_terms($post_object, 'range'); 
            $post_terms_id_array = wp_list_pluck( $post_terms_array, 'term_id' );
            if( in_array( $category->term_id, $post_terms_id_array ) ):
            ?>
            <li>
                <a href="<?php echo get_permalink($post_object->ID); ?>" target="_blank"><?php echo get_the_title($post_object->ID); ?></a>
            </li>
            <?php 
            endif;
            endforeach; 
            ?>
        </ul>
        <?php endif;?>
    </div>
    <?php 
    endforeach; 
    endif;
    ?>
</div>
<?php 
endwhile; 
wp_reset_postdata(); 
endif; 
?>

我正在创建一个仅包含术语 ID 的数组，然后检查当前的 $category ID 是否在该数组中。
