Query_posts无法与WordPress标记一起正常使用

Question

我正在编写一个循环，显示与特定WordPress标签相关的所有帖子。循环正常工作，并显示与特定标签相关的所有帖子。唯一的问题是，查询帖子不会限制要显示的帖子数量。有人可以帮忙吗？

非常感谢。

这是我的代码。

<div class="container">
    <div class="bucket-top-row row">
        <?php
        // get all the tags from the database
        $tags = get_tags();

        foreach ($tags as $tag) {

            $tag_id = $tag->term_id;
            // create a custom wordpress query
            // start the wordpress loop!
            // echo "<h2>".$tag->name."- $tag_id</h2>";
            query_posts("tag=$tag_id&post_per_page=12");

            if (have_posts()) : while (have_posts()) : the_post();

        ?>
        <div class="col-lg-4">
            <div class="bucket-wrapper-standard-top-row">
                <img class="image-bucket-standard"

                <h4 id="post-<?php the_ID(); ?>" class="bucket-text-standard">
                    <a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>">
                        <?php the_title(); ?></a></h4>
                <p class="bucket-paragraph">
                    <?php the_excerpt();?>

        <?php } // done the foreach statement ?>
