php - 按类别和 WordPress 中的查看次数计算帖子

标签 php mysql wordpress views

我正在使用 Wordpress，我正在尝试实现将返回下表的查询:

+------------+------------+------------+
|    name    |   posts    |   views    |
|------------|------------|------------|
| politics   |         10 |        311 |
|------------|------------|------------|
| economy    |         20 |        764 |
|------------|------------|------------|
| gossip     |         15 |        551 |
|------------|------------|------------|
| entertain  |          2 |        117 |
|------------|------------|------------|
| fun        |          7 |        249 |
+------------+------------+------------+

views 字段是每个类别中的帖子有多少 View ，posts 字段是每个类别中有多少帖子。

views 表具有以下结构:

view_id (INT)
view_date (DATETIME)
view_post_id (INT)

我正在使用这个结构，因为我需要知道每次访问的日期。查看帖子时，它会在此表中注册。

目前，我可以通过以下查询获取某个类别中的帖子数:

SELECT wp_terms.name,
count(wp_term_relationships.object_id) AS num_posts
FROM wp_term_taxonomy
JOIN wp_terms ON wp_term_taxonomy.term_id = wp_terms.term_id
JOIN wp_term_relationships ON wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id
JOIN wp_posts ON (wp_term_relationships.object_id = wp_posts.id AND wp_term_taxonomy.taxonomy='category' AND post_type='post' AND post_status='publish')
GROUP BY wp_terms.term_id
ORDER BY name ASC

我可以通过以下查询获取每篇文章的浏览量。

SELECT view_post_id, COUNT(view_id) as total_views, ID, post_title FROM wp_views JOIN wp_posts ON (view_post_id = ID AND post_status = 'publish') GROUP BY view_post_id

但我不知道如何合并它们。我什至不知道这是否是个好主意，因为查询可能会非常繁重。

您是否推荐使用两个查询？如果是这样，我怎么能加入第二个，因为这首先是我的问题。

谢谢!

这是 SQL 转储。

按类别计数(问题中的第一个查询)应该抛出如下内容:

+---------------+-----------+
| name          | num_posts |
|---------------|-----------|
| entertainment |         2 |
|---------------|-----------|
| fun           |         2 |
|---------------|-----------|
| gossip        |         1 |
|---------------|-----------|
| politics      |         1 |
+---------------+-----------+

观看次数应该返回类似的内容

+---------------+-------------+----+--------------------------+
| view_post_id  | total_views | ID | post_title               |
|---------------|-------------|----|--------------------------|
|            5  |           5 |  5 | fun post #1              |
|---------------|-------------|----|--------------------------|
|            7  |           3 |  7 | entertainment & fun post |
|---------------|-------------|----|--------------------------|
|            9  |           1 |  9 | entertainment & politics |
|---------------|-------------|----|--------------------------|
|           11  |           1 | 11 | gossip                   |
+---------------+-------------+----+--------------------------+

我实际寻找的查询将返回如下内容:

+------------+------------+------------+
|    name    |   posts    |   views    |
|------------|------------|------------|
| politics   |          1 |          1 |
|------------|------------|------------|
| gossip     |          1 |          1 |
|------------|------------|------------|
| entertain  |          2 |          4 |
|------------|------------|------------|
| fun        |          2 |          8 |
+------------+------------+------------+

请注意，fun 有两篇帖子，一篇有 5 次浏览，一篇有 3 次浏览，该类别总共有 8 次。

谢谢。

最佳答案

这对您有何帮助？

SELECT wp_terms.name,
  COUNT(wp_term_relationships.object_id) AS num_posts,
  SUM(total_views) AS num_views
FROM wp_term_taxonomy
JOIN wp_terms ON wp_term_taxonomy.term_id = wp_terms.term_id
JOIN wp_term_relationships ON wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id
JOIN wp_posts ON (wp_term_relationships.object_id = wp_posts.id AND wp_term_taxonomy.taxonomy='category' AND post_type='post' AND post_status='publish')
JOIN (
       SELECT COUNT(*) as total_views, view_post_id
       FROM wp_views 
       GROUP BY view_post_id
     ) wpv ON wpv.view_post_id=wp_posts.id
GROUP BY wp_terms.term_id
ORDER BY name ASC

回复:我什至不知道这是否是个好主意，因为查询可能会非常繁重。

查询的繁重程度取决于您的数据和索引。如果执行速度低于可接受水平，请随时使用生成的 EXPLAIN 更新您的帖子(或创建新帖子)。无论如何，如果您可以将结果缓存在某处(MySQL 中的报告/临时表、磁盘上或内存缓存中)并且只定期计算它(而不是每次 计算)，您应该没问题。
