使用嵌套WP_QUERY时重复

时间：2016-01-10 作者：jasenmp

我想我错过了一些非常简单的事情，但我已经不知所措，希望被指向正确的方向。一点背景知识。

我在一家创意机构的网站上工作。我正在使用分类法将人们和他们所从事的项目联系起来。

在我的循环中查询post类型“people”，然后在该循环中查询post类型“projects”，并在projects查询中传递一个查询“project\\u association”分类的参数。当每个创意都有自己的页面时，循环就可以了，但我们正在转向单页面布局，这就是我遇到的问题。

有些创意人员可能参与了另一个项目。因此，创意一可能与项目一相关，创意二也可能与项目一相关。我需要在其中显示。

发生的事情是，当我运行循环时（在本例中，它运行了三次-列出三个创意），它复制了项目。所以创意一会有项目一，但创意二会有项目一的两次演出，创意三会有项目一的三次演出。

发生的事情是显而易见的，我只是不完全确定该怎么办。

任何帮助都将不胜感激。代码如下：

没关系，我知道了。

对于任何可能遇到类似问题的人。见下文。

主回路：

if ( $the_query->have_posts() ) {
    while ( $the_query->have_posts() ) {
        unset($do_not_duplicate);
        $the_query->the_post();
    }
}
二次回路：

if ( $projects_query->have_posts() ) {
    while ( $projects_query->have_posts() ) {
        $do_not_duplicate[] = get_the_ID();
        if( in_array( get_the_ID(), $do_not_duplicate) ) 
            continue;
    }
}

为什么WP-Query的拼写是这样的？

我不熟悉PHP和WordPress，我很好奇：为什么WP查询是大写的？这是基于查询类型的PHP命名约定吗？还是怎样谢谢
