Question

我正在尝试将sql查询转换为wordpress查询，但却无法理解它是如何完成的？

查询我尝试转换为new wp_query

$query = "  SELECT SQL_CALC_FOUND_ROWS distinct wp_posts.ID
            FROM   wp_posts
                   INNER JOIN wp_postmeta
                           ON ( wp_posts.id = wp_postmeta.post_id )
                   INNER JOIN wp_postmeta AS mt1
                           ON ( wp_posts.id = mt1.post_id )
            WHERE  1 = 1
                   AND wp_posts.id NOT IN ( 0 )
                   AND wp_posts.post_type = 'topic'
                   AND ( wp_posts.post_status = 'publish'
                          OR wp_posts.post_status = 'closed'
                          OR wp_posts.post_status = 'reported' )
                   AND ( wp_postmeta.meta_key = '_bbp_last_active_time')
            GROUP  BY wp_posts.id
            ORDER  BY wp_postmeta.meta_value DESC
            LIMIT  0, 10 
        ";
$topics = $wpdb->get_results($query, OBJECT);

所以我可以使用

while($topics->have_posts()) : $topics->the_post(); ?>

喜欢

$args = array(); // how do I convert to this.
$topics = new WP_query($args);

Answer 1

尝试：

$wpq = new WP_Query();
$wpq->parse_query($query);
$posts = $wpq->get_posts();

或使用标准的WP_Query函数：

$wpq = new WP_Query($query);

Answer 2

我尝试过bobdye的解决方案，但事实证明它无法正常工作。就我所知，设置一个可以使用the_title()，$post->ID等的循环的唯一方法是这样工作：

global $post;

$sql_results = $wpdb->get_results( $sql_query, OBJECT);

if ($sql_results) {
    foreach ($sql_results as $post) {
      setup_postdata($post);

      // You're in the loop now. You can access all the $post objects
      // and functions like in any other wp loop.
      // example: the_title();

    }
  wp_reset_postdata();
}

这个问题就是分页。但我相信这个答案整齐地解决了这个问题： https://wordpress.stackexchange.com/questions/21626/pagination-with-custom-sql-query#28717

使用新的wp_query将sql查询转换为wordpress查询
