我有一个查询，它从所有类别中提取帖子，除了一个ID为2的类别。在第一个循环中，我有一个if语句来计算偶数和奇数帖子，以改变我的html（工作正常）。

在每2篇文章的末尾插入一个div（我可以这样做），在该div中，我需要从ID为2的类别中随机查询一篇文章。

很难理解如何在循环中循环。我见过一些不同的例子，但似乎没有一个是有效的。

这是我的代码精简了一点。

<?php 
$counter = 0;
query_posts(\'cat=-2&orderby=date&order=DESC\'); while (have_posts()): the_post(); $counter++; ?>
    <?php if( $counter % 2 == 0 ) : ?>

        <!-- Displaying even posts here -->

    <?php else: ?>

        <!-- Displaying odd posts here -->

    <?php endif; ?>
    <?php if( $wp_query->current_post == 1 ) { ?>
        <div class="post__splitter">

            <!-- This is where a need to query a random post from the category with an ID of 2.  -->
            <!-- query_posts(\'cat=2&orderby=rand&post_per_page=-1\') -->

        </div>
    <?php } ?>
<?php endwhile; ?>

这是我到目前为止的全部代码。。。遇到了显示所有帖子的问题，加上大约1000万个帖子。。我想不出来。。。

<?php 
$counter = 0;
$outer_query = new WP_Query( array( \'cat\' => \'-2\', \'orderby\' => \'date\', \'order\' => \'DESC\' ) ); while ($outer_query->have_posts()): the_post(); ?>
    <?php if( $counter % 2 == 0 ) : ?>  
        <div class="post">
            <div class="post__thumbnail"><?php the_post_thumbnail(); ?></div>
            <div class="post__content_wrapper">
                <div class="post__content">
                    <div class="post__title"><a href="<?php the_permalink();?>"><?php the_title(); ?></a></div>
                    <div class="post__caption"><?php the_excerpt(); ?></div>
                    <div class="post__details">
                        <a class="post__date" href="<?php the_permalink();?>"><?php the_date(\'F j, Y\', \'Posted on \'); ?></a>
                        <?php the_tags(\'<span class="post__tags">Tagged with: \',\', \',\'</span>\'); ?>
                    </div>
                </div>
            </div>
        </div>
    <?php else: ?> 
        <div class="post post--odd">
            <div class="post__content_wrapper">
                <div class="post__content">
                    <div class="post__title"><a href="<?php the_permalink();?>"><?php the_title(); ?></a></div>
                    <div class="post__caption"><?php the_excerpt(); ?></div>
                    <div class="post__details">
                        <a class="post__date" href="<?php the_permalink();?>"><?php the_date(\'F j, Y\', \'Posted on \'); ?></a>
                        <?php the_tags(\'<span class="post__tags">Tagged with: \',\', \',\'</span>\'); ?>
                    </div>
                </div>
            </div>
            <div class="post__thumbnail"><?php the_post_thumbnail(); ?></div>
        </div>
    <?php endif; ?>
    <?php if( $wp_query->current_post == 1 ) { ?>
        <div class="post__splitter">
            <?php
                $inner_query = new WP_Query(array(\'cat\' => 2, \'orderby\' => \'rand\'));    

                the_content();
            ?>
        </div>
    <?php } ?>
<?php endwhile; ?>

Final Working Edit

<?php 
$counter = 0;
$args = array (
    \'order\' => \'DESC\',
    \'orderby\'=> \'date\',
    \'cat\' => \'-2\',
);

// The Query
$outer_query = new WP_Query( $args ); if ( $outer_query->have_posts() ) : while ( $outer_query->have_posts() ) : $outer_query->the_post(); $counter++; ?>
<?php if( $counter % 2 == 0 ) : ?>  
        // even posts
    <?php else: ?> 
        // odd posts
    <?php endif; ?>
    <?php if( $outer_query->current_post ==1 ) { ?>

        <?php $args2 = array(
            \'cat\' => \'2\',
            \'posts_per_page\' => \'1\',
            \'orderby\' => \'rand\',
        );
        $inner_query = new WP_Query( $args2 ); if ( $inner_query->have_posts() ) : while ( $inner_query->have_posts() ) : $inner_query->the_post(); ?>

            // inner query pulling random post. 

        <?php endwhile; endif; ?>
    <?php } ?>

<?php endwhile; endif; ?>
