请尝试这样的事情......

<?php
    global $wpdb; 
    $get_results= $wpdb->get_results( "SELECT p.post_title, pm2.meta_value , pm3.meta_value   
                    FROM wp_posts as p
    INNER JOIN wp_postmeta AS pm1 ON pm1 .post_id = p.ID

    INNER JOIN wp_postmeta AS pm2 ON pm2 .post_id = p.ID AND pm2.meta_key='side_post_meta_id' AND pm2.meta_value like '%$search_term%'

    INNER JOIN wp_postmeta AS pm3 ON pm3 .post_id = p.ID AND pm3 .meta_key='side_post_id' AND pm3 .meta_value like '%$cat_find%'

    WHERE p.post_status = 'publish' AND p.post_type = 'post' ORDER BY p.post_date DESC LIMIT 0,10");

    echo '<pre>';
    print_r($get_results);
    echo '</pre>';

wpdb查询加入帖子和帖子元
