如何在公文包页面上仅显示1个类别中的公文包项目？

时间：2014-07-23 作者：Jamie Ludlow

我有一个网站，我正在为我的一个客户，其中有一个投资组合页面，你可以在这里看到。。。

http://lenhamsportscars.com/cars-for-sale

您会注意到，当时有一个按类别（待售汽车或已售出汽车）过滤的选项。我需要修改代码，使其自动只显示我选择的类别中的投资组合项目，而不是在同一页上同时显示这两个项目。

这是当前需要修改的代码。。。

我已经对此进行了几天的研究和尝试，但我对代码不太在行，无法让它正常工作。任何帮助都将不胜感激，因为客户希望此网站在a.s.a.p.完成。

谢谢

根据您是否打算使用此模板在其他地方显示其他类别，您可能需要一份以该类别命名的公文包模板文件的副本。

要从post type“portfolioitems”中选择要显示的单个类别，请修改以下行：

$wp_query = new WP_Query(array(\'post_type\' => \'portfolioitems\',\'posts_per_page\' => 50,\'paged\'=> $paged));
收件人：

$wp_query = new WP_Query(array(\'post_type\' => \'portfolioitems\', \'cat=4\', \'posts_per_page\' => 50,\'paged\'=> $paged));
这假设所需类别的ID为4。只需向WP\\u查询数组添加一个额外的键/值，就会包含该过滤器，并排除任何与额外条件不匹配的帖子。

您可以按名称、ID等筛选类别。这里详细介绍了可用的各种方法
WP Codex ref 对于类别参数。

**编辑到分类查询**基于此附加信息，您似乎需要特定于自定义帖子类型“portfolioitems”的分类过滤器。

$wp_query = new WP_Query(array(\'post_type\' => \'portfolioitems\', \'section\' => \'sectionname\', \'posts_per_page\' => 50,\'paged\'=> $paged));
将“sectionname”替换为所需节的名称。有关的完整详细信息taxonomy parameters

我正在尝试显示一些面包屑的帖子类别。目前，我有：the_category(\' / \', \'multiple\'); 但出于某种原因，它两次声明了父类别（我只想parent > child):FASHION / DAILY FASHION CANDY / FASHION 它应该是：FASHION / DAILY FASHION CANDY 有人知道它为什么这样做，以及如何改变它吗？
