【中文标题】显示 WooCommerce 自定义分类法 ACF 字段

【英文标题】：Display WooCommerce Custom Taxonomy ACF Field

【问题描述】：

我为 woocommerce 产品“coffee_type”创建了自定义分类。 我为此分类创建了一个 ACF 图像字段“coffee_type_image”。

我想在产品页面上显示带有链接而不是分类名称的图像。 我在这里阅读了大多数关于在分类上显示 acf 图像的文章，但每一篇文章都是关于使用存档分类页面而不是产品页面。 我正在编辑 single-product.php（确切地说是 content-single-prodct.php）。

这是我当前的循环

<?php $wcatTerms = get_terms('coffee_type', array('hide_empty' => 0, 'parent' => 0));
foreach ($wcatTerms as $wcatTerm):
?>
<ul>
   <li>
      <a href="<?php echo get_term_link($wcatTerm->slug, $wcatTerm->taxonomy); ?>"><?php echo $wcatTerm->name; ?></a>
        <?php $taxonomy = $queried_object->taxonomy;?>
   </li>
</ul>
<?php
endforeach;
?>

这是#wcatTerm 的var_dump

object(WP_Term)[3704]
  public 'term_id' => int 33
  public 'name' => string 'coffee and chicory' (length=18)
  public 'slug' => string 'coffee-and-chicory' (length=18)
  public 'term_group' => int 0
  public 'term_taxonomy_id' => int 33
  public 'taxonomy' => string 'coffee_type' (length=11)
  public 'description' => string '' (length=0)
  public 'parent' => int 0
  public 'count' => int 2
  public 'filter' => string 'raw' (length=3)

这是get_queried_object()的var_dump；

如何在 ACF 字段中显示“coffee_type_image”以及指向存档页面的链接？我不知道如何将 ACF 传递给此分类法以使用 get_field() 显示图像；

我尝试过类似的东西

<?php $term = get_field('coffee_type_image', $wcatTerm->term_id);?>

和

<?php $term = get_field('coffee_type_image', $wcatTerm->term_id, $wcatTerm->taxonomy);?>

但它们总是返回 null 谢谢

【参考方案1】：

我刚刚找到了我的问题的答案。如果其他人需要，我会发布。

<?php $term = get_field('coffee_type_image', 'coffee_type_' . $wcatTerm->term_id);?>
 <a href="<?php echo get_term_link($wcatTerm->slug, $wcatTerm->taxonomy); ?>"><img src="<?php echo $term; ?>"  class="img-responsive"></a>
