按发布的自定义帖子数量按顺序获取 WordPress 作者

Question

在我的 WordPress v5.8.1 中，我有一个在自定义帖子song和poem. 使用下面的代码，我可以获得在两个或一个自定义帖子中发布的作者列表。

 $authors = get_users(array(
        'who' => 'authors',
        'has_published_posts' => array('song','poem'),
        'orderby' => 'post_count',
        'order' => 'DESC',
        'number' => '15'
 ));

下面的代码列出了所有作者及其帖子数：

foreach ($authors as $user) {
   $name = $user->first_name . ' ' . $user->last_name;
   $songs = count_user_posts($user->ID, $post_type = "song");
   $poems = count_user_posts($user->ID, $post_type = "poem");
   echo $name.' has '. $songs .' songs, and '. $poems .' poems;
}

在参数中'orderby' => 'post_count'，我希望首先显示组合自定义帖子数最高的作者列表，但它是随机显示的，没有顺序，既不是 bypost_counts也不是ID。

如何对帖子总数最多的作者进行排序？

Answer 1

尝试下面的代码。

$authors = get_users(array(
    'who' => 'authors',
    'has_published_posts' => array('song','poem'),
    'orderby' => 'post_count',
    'order' => 'DESC',
    'number' => '15'
));

创建一首array并计算诗歌+歌曲的总数

$author_posts = array();

foreach ($authors as $user) {
    $name = $user->first_name . ' ' . $user->last_name;
    $songs = count_user_posts($user->ID, $post_type = "song");
    $poems = count_user_posts($user->ID, $post_type = "poem");
    $author_posts[] = array(
        'total' => $songs+$poems,
        'label' => $name.' has '. $songs .' songs, and '. $poems .' poems'
    );
}

现在使用 `usort 按总计对数组进行排序。

usort($author_posts, function($a, $b) {
    if($a['total']==$b['total']) return 0;
    return $a['total'] < $b['total']?1:-1;
}); 

打印输出。

foreach ( $author_posts as $key => $author_post ) {
    echo $author_post['label']."</br>";
}

完整代码。

$authors = get_users(array(
    'who' => 'authors',
    'has_published_posts' => array('song','poem'),
    'orderby' => 'post_count',
    'order' => 'DESC',
    'number' => '15'
));

$author_posts = array();

foreach ($authors as $user) {
    $name = $user->first_name . ' ' . $user->last_name;
    $songs = count_user_posts($user->ID, $post_type = "song");
    $poems = count_user_posts($user->ID, $post_type = "poem");
    $author_posts[] = array(
        'total' => $songs+$poems,
        'label' => $name.' has '. $songs .' songs, and '. $poems .' poems'
    );
}

usort($author_posts, function($a, $b) {
    if($a['total']==$b['total']) return 0;
    return $a['total'] < $b['total']?1:-1;
}); 

foreach ( $author_posts as $key => $author_post ) {
    echo $author_post['label']."</br>";
}

经过测试并有效。

您的块内有错误foreach，这可能是导致问题的原因。使用这个代替：

foreach ($authors as $user) {
   $name = $user->first_name . ' ' . $user->last_name;
   $songs = count_user_posts($user->ID, "songs");
   echo $name.' has '. $songs .' songs ';
}

简而言之，$post_type = "songs"只需将替换为"songs"。有关接受的参数的详细信息，请参阅文档。

编辑：我误解了这个问题。看看你的查询，一切都应该如此，所以我会在其他地方寻找问题的根源。您是否有可能更改查询的插件或过滤器？您可以直接在数据库中重现您的查询吗？它可以在那里工作吗？（以排除表或索引损坏）
