首先，我建议在类别上进行此更改。php文件，作为归档文件。根据Wordpress Theme Hierarchy 文件系统。

尝试添加以下两个查询：

$cats = get_the_category();
    $cat_id = $cats[0]->term_id;


        // news
        $args = array(
    \'post_type\' => \'news\',
    \'posts_per_page\' => 5,
    \'cat\'     => $cat_id,
);
$query = new WP_Query($args);

if($query->have_posts() ) : 
    while( $query->have_posts() ) :
        $query->the_post();
    endwhile; 
endif; 

wp_reset_postdata(); 

    // articles
$args = array(
    \'post_type\' => \'articles\',
    \'posts_per_page\' => 5,
    \'cat\'     => $cat_id,
);
$query = new WP_Query($args);

if($query->have_posts() ) : 
    while( $query->have_posts() ) :
        $query->the_post();
    endwhile; 
endif; 

wp_reset_postdata(); 

创造taxonomy-categories.php 或者在你的archive.php 添加以下代码以获取帖子article 和news 当前类别的职位类型。我假设这两种帖子类型的分类是categories. 改变categories 使用您的分类法和post_type 与您的新闻和文章类型从下面的代码。

 # Article 
 $articleargs = array(
        \'post_type\' => \'article\',
        \'posts_per_page\' => 5,
        \'tax_query\' => array(
            \'relation\' => \'AND\',
            array(
                \'taxonomy\' => \'categories\',
                \'field\'    => \'name\',
                \'terms\'    => get_queried_object()
            )
        ),
    );
    $articlequery = new WP_Query( $articleargs );

     if( $articlequery->have_posts() ) : 
        echo "<h2>Articles</h2>";
        echo "<ul>";
        while( $articlequery->have_posts() ) : $articlequery->the_post();   
            echo "<li>".get_the_title()."</li>";
         endwhile; 
         echo "</ul>";
    endif; 
    wp_reset_postdata(); 

    # news
    $newsargs = array(
        \'post_type\' => \'news\',
        \'posts_per_page\' => 5,
        \'tax_query\' => array(
            \'relation\' => \'AND\',
            array(
                \'taxonomy\' => \'categories\',
                \'field\'    => \'name\',
                \'terms\'    => get_queried_object()
            )
        ),
    );
    $newsquery = new WP_Query( $newsargs );

     if( $newsquery->have_posts() ) : 
        echo "<h2>News</h2>";
        echo "<ul>";
        while( $newsquery->have_posts() ) : $newsquery->the_post();   
            echo "<li>".get_the_title()."</li>";
         endwhile; 
         echo "</ul>";
    endif; 
    wp_reset_postdata(); 

这个get_the_category() 函数从循环中检索分配给第一篇文章的类别，这不是您的意思。我想audit, income, tax, 等是内置类别，而不是自定义分类法（在这种情况下，需要替换cat 的参数WP_Query 到tax_query).

创造category.php 如果文件不存在，请通过复制archive.php. 这样，模板将仅在类别页面上使用。

的IDcurrently viewed 您可以使用的类别get_queried_object_id(). 您不必在category.php 文件，它将始终是正确的。有了类别ID，就可以将它们插入查询参数中，并且只接收属于它的帖子。

如果您打算仅将模板应用于选定类别（审计、收入、税务），而不是全部，请使用{$type}_template 滤器

//
// ge ID of the  current category
$cat_id = get_queried_object_id();

//
// get \'news\' posts from current category 
$args = array(
    \'post_type\' => \'news\',
    \'posts_per_page\' => 10,
    \'cat\'       => (int)$cat_id,  // <==
    //\'meta_query\' => array(
    //    array(
    //        \'key\' => \'recommended_article\',
    //        \'value\' => \'1\',
    //        \'compare\' => \'=\',    // <== 
    //    )
    )
);
$query = new WP_Query( $args );
//
// display posts
// 
wp_reset_postdata();


//
// get \'articles\' posts from current category 
$args = array(
    \'post_type\' => \'articles\',   // <==
    \'posts_per_page\' => 10,
    \'cat\'       => (int)$cat_id,
    //\'meta_query\' => array(
    //    array(
    //        \'key\' => \'recommended_article\',
    //        \'value\' => \'1\',
    //        \'compare\' => \'=\',
    //    )
    )
);
$query = new WP_Query( $args );
//
// ...
// 
wp_reset_postdata();
