我正试图在网站首页显示每个帖子的第一个图片附件。下面的代码适用于其他页面，但分页不适用于is_front_page().

显示1-20个缩略图的第一页，单击“下一步”将进入显示21-40个缩略图的第2页，以此类推。

我已经重置了永久链接，PHP日志中没有错误。

有什么想法吗？

function homepage_grid() {
global $wpdb, $post;

                query_posts(\'showposts=\' . $limit . \'&paged=\' . $paged . \'&orderby=date&order=DESC\');
                ?>
