Paginate Wordpress $ wpdb查询？

Question

我有这个问题:

    <?php
    $query= "SELECT wposts.* FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta WHERE wposts.ID = wpostmeta.post_id AND wpostmeta.meta_key = 'votes' AND wposts.post_status = 'publish' AND wposts.post_type = 'post' ORDER BY CAST(wpostmeta.meta_value AS SIGNED) DESC LIMIT 10";
    $posts = $wpdb->get_results($query, OBJECT);
    if ($posts ) : foreach ($posts as $post):
    setup_postdata($post);
    ?>
    // Post here 
    <?php endforeach; endif; ?>
    <div class="pagination">
        <?php wp_pagenavi(); ?>
    </div>

我正在使用这个,因为Wordpress无法正确排序使用数字的meta_values,无论如何...一切正常,但我不知道如何使用wp_pagenavi对此进行分页.

任何的想法？

感谢@jaziel matoso,

下面代码有效:

    global $wp_query; 
    $query = "SELECT wposts.* FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta 
       WHERE wposts.ID = wpostmeta.post_id AND wpostmeta.meta_key = 'votes'
       AND wposts.post_status = 'publish' AND wposts.post_type = 'post' ORDER BY 
       CAST(wpostmeta.meta_value AS SIGNED) DESC";

    $total_record = count($wpdb->get_results($query, ARRAY_A));

    $paged      = get_query_var('paged') ? get_query_var('paged') : 1;
    $post_per_page  = get_option('posts_per_page');
    $offset         = ($paged - 1)*$post_per_page;
    $max_num_pages  = ceil($total_record/ $post_per_page);

    $wp_query->found_posts = $total_record;
    // number of pages 
    $wp_query->max_num_pages = $max_num_pages;

    $limit_query    =   " LIMIT ".$post_per_page." OFFSET ".$offset;    

    $result =   $wpdb->get_results($query.$limit_query,OBJECT);// return OBJECT

   if($result):
    foreach ($result as $post):
      setup_postdata($post);
          ?>
           <h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
           <p><?php the_content(); ?></p>
        <?php
        endforeach;
        ?>
       <div class="navigation"><?php wp_pagenavi(); ?></div>
        <?php
   endif;

完成!
