我创建了一个自定义的帖子类型"Projects"，并为其附加了一个客户分类法"Services"。我已经将分类法设置为类别(我也尝试了标记，但仍然存在相同的问题(。它显示在wordpress管理员中，我可以在项目帖子上创建标签/类别。标记/类别保存在数据库中，因为它们仍然显示在编辑后页面上。然而，我很难把它们展示在前端。请参阅下面来自我的function.php、archive-projects.php和single-projects.hp的代码。请注意，single-project.php文件还包括一个名为"项目集合"的自定义字段，该字段迭代各个项目组合图像和副本。此外，标签根本不会在HTML中呈现(当在Google Chrome中检查元素时(。感谢

我认为与其将此代码块用于您的标签
$tags = get_the_tags();
if($tags):
foreach($tags as $tag): ?>
<dd>
<a href="<?php echo get_tag_link($tag->term_id); ?>"><?php echo $tag->name; ?></a>
</dd>
<?php endforeach; endif; ?>
试试这个代码块。我认为它会解决你的问题
$tags = wp_get_post_terms(get_the_ID(), 'Your tag/taxonomy slug name', array("fields" => "all"));
if($tags):
foreach($tags as $tag): ?>
<dd>
<a href="<?php echo get_tag_link($tag->term_id); ?>"><?php echo $tag->name; ?></a>
</dd>
<?php endforeach; endif; ?>
明确地说，不要使用get_the_tags((使用wp_get_post_terms((函数。我希望这将解决您的标签问题。：(
AR。阿里夫，非常感谢你的回答。它帮助我解决了下一个问题。我为公文包项目添加了类别。管理面板中的还可以，但前端的输出很奇怪。一个投资组合项目的类别在另一个项目附近输出。
所以我换了这个$portfolio_categories=get_the_trms(get_the_ID((，'portfolio_category'(；
用这个$portfolio_categories=wp_get_post_terms(get_the_ID((，'portfolio_category'，数组("字段"="所有"(；
在主题的模板/分类法/类别-投资组合.php中(当然在子主题中(
并且它最终正确地工作。
