wp查询中的wp查询

Question

我做了两个wp查询循环，其中一个是在循环内出了问题，我想不出这里是代码，内部wp查询图像cpt与主查询cpt相关。

$maincontest = new WP_Query(array(
                'posts_per_page' => 3,
                'post_type' => 'contest',
                'post_status' => 'any'
            ));
            while($maincontest->have_posts()){
                $maincontest->the_post(); ?>
            <div class = "listloopmain">    
                <a href="<?php the_permalink(); ?>"> 
                    <div class = "listcontestitem">
                        <div class = "listimage">
                            <?php
                                $toplogo = new WP_Query(array(
                                    'posts_per_page' => 1,
                                    'post_type' => 'logo',
                                    'orderby' => 'rand'
                                ));
                                while($toplogo->have_posts()){
                                    $toplogo->the_post();
                                    $image = wp_get_attachment_url( get_post_thumbnail_id($post->ID), 'thumbnail' ); ?>
                                    <div class ="listim">
                                        <img src="<?php echo $image ?>"/>   
                                    </div>
                                <?php }
                                wp_reset_postdata();
                            ?>
                        </div>
                        <div class = "title_des">
                            <div class = "listtitle">
                                <h4>
                                    <?php the_title(); ?>
                                </h4>
                            </div>
                            
                            <div class = "listdescription">
                                <?php echo wp_trim_words(get_the_content(), 20); ?>
                            </div>
                        </div>
                        <div class = "listcontestprice">
                            $ <?php the_field('price'); ?>
                        </div>
                        <div class = "listtime">
                            5 Days
                        </div>
                                                            
                    </div>
                </a>
            </div>
                                
                <?php } ?>
            </div>
                <div class ="my-pagination">
                <?php           
                    echo paginate_links(array(
                        'prev_text' => __( '<' ),
                        'next_text' => __( '>' )
                    )); 
                    wp_reset_postdata();            
                ?>

问题是主查询固定链接是正确的，但每个循环的内容都是相同的。图像查询工作正常。有人能帮上忙吗？

提前感谢

在代码的这一部分-

while($toplogo->have_posts()){
    $toplogo->the_post();
    $image = wp_get_attachment_url( get_post_thumbnail_id($post->ID), 'thumbnail' ); ?>
    <div class ="listim">
        <img src="<?php echo $image ?>"/>   
    </div>
<?php }
**wp_reset_postdata();**

使用$toplogo->reset_postdata();

可以在这里找到的reset_postdata函数的引用- https://developer.wordpress.org/reference/classes/wp_query/reset_postdata/。

此外，这里有一篇很好的文章解释了它是如何使用的- https://neliosoftware.com/blog/the-problems-of-using-nested-loops-in-wordpress/。

嗨，我得到了解决方案，想要主要自定义查询只显示私人帖子。通过过滤pre_get_posts和set方法实现。谢谢大家

function contest_adjust_query($query){
    if (!is_admin() AND is_post_type_archive('contest') AND $query->is_main_query()) {
        $query->set('post_status', 'private');
        $query->set('post_status', array('publish', 'private'));
    }
}

add_action('pre_get_posts', 'contest_adjust_query');
