我有一个主题，其投资组合使用过滤器（全部，新，旧）来显示类别。但是，在加载时，我希望特定（"新"）类别是唯一显示的类别。
然后，如果用户希望查看过去的产品，他们会单击"旧"等等。
请记住，我将创建另一个投资组合，并且该投资组合的新项目只会在加载时显示。
我已经试图找到答案几个小时了，但我还没有能够找到它。
以下是投资组合 php 页面的代码：

这个问题与WordPress本身无关，而是与您或您的主题用于对数据进行排序的插件有关。
在这种情况下，它使用同位素，这是过滤您在页面上看到的结果的原因。
通过在过滤方面解决同位素的文档，我们看到过滤器可以通过功能或按钮来完成，在这种情况下，我们使用两者的组合，因为我们希望数据在单击时更改，但同时它已经需要过滤，如您所要求的那样。
因此，为了解决这个问题，它是同位素功能文件中的一行：
$container.isotope({
itemSelector : '.element',
filter: '.workshops'
});
我刚刚添加了最后一个。
除此之外，您只需要破解您提供的代码即可将"selected"类添加到按钮中：
echo( '<ul id="filters" class="option-set">
<li><a href="#" data-filter="*" class="show-all">All</a></li>' );
foreach ( $categories as $category ) { ?>
<li>
<span class="sep">/</span>
<a href="#<?php echo $category->slug; ?>" <?php if($category->slug == 'workshops'): echo 'class="selected"'; endif;?>data-filter=".<?php echo $category->slug; ?>"><?php echo $category->name;?></a>
</li>
<?php
}
echo( '</ul>' );
现在一些注意事项：
- 如果您更改 slug，这将停止工作，因为它正在检查类"研讨会"，如果您这样做，您需要编辑上面提供的代码;
- 同位素被屏蔽在主题的自定义jquery文件中，这根本不是一个好的做法，特别是对于维护问题。
