仅针对 blogspot 中的特定标签显示广告 (AdSense)

Question

我想在特定标签中显示广告，如下所示：

但这不起作用。它什么也没告诉我。我该如何解决这个问题？我想为 Gartenblog、Foodblog、Reiseblog、Fotoblog 和 Blogging 标签显示 Google AdSense，如果没有这些标签，它应该显示另一个广告。我该怎么做？

<b:if cond='data:post.labels none (label => label.name in ["Gartenblog","Foodblog","Familienblog","Reiseblog","Fotoblog","Blogging"])'>
<b:if cond='data:post.labels any (label => label.name == ["Gartenblog","Foodblog","Familienblog","Reiseblog","Fotoblog","Blogging"])'>

如果我只使用一个标签，它可以正常工作，而不是多个。

Answer 1

检查长度：

<b:if cond='(data:post.labels where (label => label.name in ["Gartenblog","Foodblog","Familienblog","Reiseblog","Fotoblog","Blogging"])).length gt 0'>
  <!-- Ad One -->
<b:else/>
  <!-- Ad Two-->
</b:if>
