Question

编辑：我在另一个帖子中详细阐述了这个主题：List categories by author ~ WITH COUNTER ~ (Wordpress) ......它可能更适合你。

当我在我的分类页面时，我希望读者看到谁在那里发帖，并按作者过滤。（例如，Activism有127个帖子，37个是Adrian，12个是James，等等......）我已经尝试了一百万个东西，但没有什么能满足我的简单任务！那里有类似经历的人吗？

这就是我所拥有的：

<?php

$curauth = $wp_query->get_queried_object();

$auth_id = 1;
$cat_id = 2411;

$sql = "SELECT COUNT(*)
FROM $wpdb->posts p
JOIN $wpdb->term_relationships tr ON (p.ID = tr.object_id)
WHERE post_author = $auth_id
AND post_type = 'post'
AND post_status = 'publish'
AND post_date <= NOW()
AND tr.term_taxonomy_id = $cat_id
";
$post_count = $wpdb->get_var($sql);
echo "This Author has published $post_count posts in Activism<br />";

?>

编辑：

好的，这段代码有效!!! ......我很高兴，但仍然有点疑惑。为什么这样做，而上面的那个没有？

<?php 

$auth_id = 1; 
$cat_id = 2411;

$counter = "SELECT COUNT(*) 
FROM $wpdb->posts
LEFT JOIN $wpdb->term_relationships ON($wpdb->posts.ID = $wpdb->term_relationships.object_id)
LEFT JOIN $wpdb->term_taxonomy ON($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)
WHERE $wpdb->term_taxonomy.term_id = $cat_id
AND $wpdb->term_taxonomy.taxonomy = 'category'
AND $wpdb->posts.post_status = 'publish'
AND post_author = '$auth_id'
";

$user_count = $wpdb->get_var($counter);


echo "Author... has $user_count posts in Activism<br />";

?>

列出按作者（WP）过滤的特定类别的帖子数
