我正在尝试为一个帖子滑块编写一些代码，目前我的代码涉及两个WP_Querys、 一个在另一个里面，但我忍不住觉得可能有一种更有效的方式来实现我想要实现的目标。

步骤包括：

使用WP\\u查询，检查某一帖子类型的已发布帖子数量=4，我想在页面中添加一个滑块，所以我开始打印滑块容器$num_posts) 计算出我想在下一次查询中打印多少帖子。如果有>=12可用，我想打印全部12。如果有8到11个，我只想打印8个。如果有4到7个可用，我只想打印出4个$postsToPrint) 进入showposts 作为第二个WP\\u查询的参数WP_Querys这似乎效率低下。

此处代码说明：

    // Initial query which only exists so I can count available posts

    $args = array (
        \'post_type\'              => \'mytheme_posttype\',
        \'post_status\'            => \'publish\',
        \'showposts\' => 12
    );

    $sliderQuery = new WP_Query( $args );


    // Count how many available posts there are for my slider
    $num_posts = $sliderQuery->post_count;

    if ($num_posts >=4) : ?>

    // Want to add a slider if posts >= 4, so start printing out slider container HTML here.

    // I then want to check how many posts were collected in the above query, and only print out a certain number depending on how many there are available

        // if there are 12 available posts, print out all 12
        if ($num_posts >= 12) {
            $postsToPrint = 12;
        }

        //  else if there are between 8 and 11 available posts, only print out 8
        elseif ($num_posts >=8) {
            $postsToPrint = 8;
        }

        // if there are between 4 and 7 available posts, only print out 4
        else {
            $postsToPrint = 4;
        }

        // Second query for actually printing out posts.

        $args = array (
            \'post_type\'              => \'mytheme_posttype\',
            \'post_status\'            => \'publish\',
            \'showposts\' => $postsToPrint
        );

        $loop = new WP_Query( $args );

        while ( $loop->have_posts() ) : $loop->the_post();

            // print out post thumbnail and some other post data in slider

        endwhile;

        // close slider container HTML

    endif;
