Question

此页面显示了许多最近的帖子，而我希望它只显示最新的帖子。如何删除此循环并将其替换为最近的一次迭代？

    <?php while (have_posts()) : the_post(); ?>

        <div <?php post_class() ?> id="post-<?php the_ID(); ?>">
        <span class="postmetadata"><?php the_category(' / ') ?> &mdash; <?php edit_post_link('Edit', '', ' &mdash; '); ?>  <?php comments_popup_link('No comments', '1 comment', '% comments'); ?></span><br/>
            <small><span class="date"><?php the_time('d') ?></span><br /><?php the_time('M y') ?> <!-- by <?php the_author() ?> --></small>
            <h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>



            <div class="entry">
                <?php the_content('<em>Continue reading &rarr;</em>'); ?>
            </div>
            <div class="clearfix"></div>

        </div>

    <?php endwhile; ?>

Answer 1

如果帖子已经按照正确的顺序排序，你只想要第一个，你可以将其更改为：

<?php if (have_posts()): the_post(); ?>

    <div <?php post_class() ?> id="post-<?php the_ID(); ?>">
    <span class="postmetadata"><?php the_category(' / ') ?> &mdash; <?php edit_post_link('Edit', '', ' &mdash; '); ?>  <?php comments_popup_link('No comments', '1 comment', '% comments'); ?></span><br/>
        <small><span class="date"><?php the_time('d') ?></span><br /><?php the_time('M y') ?> <!-- by <?php the_author() ?> --></small>
        <h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>



        <div class="entry">
            <?php the_content('<em>Continue reading &rarr;</em>'); ?>
        </div>
        <div class="clearfix"></div>

    </div>

<?php endif; ?>

修改全局$ query_string变量：

<?php
global $query_string;
$query_string .= "&posts_per_page=1"; // append the post count limit
query_posts($query_string); // perform the query
?>

<?php while (have_posts()) : the_post(); ?>

    <div <?php post_class() ?> id="post-<?php the_ID(); ?>">
    <span class="postmetadata"><?php the_category(' / ') ?> &mdash; <?php edit_post_link('Edit', '', ' &mdash; '); ?>  <?php comments_popup_link('No comments', '1 comment', '% comments'); ?></span><br/>
        <small><span class="date"><?php the_time('d') ?></span><br /><?php the_time('M y') ?> <!-- by <?php the_author() ?> --></small>
        <h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>

        <div class="entry">
            <?php the_content('<em>Continue reading &rarr;</em>'); ?>
        </div>
        <div class="clearfix"></div>

    </div>

<?php endwhile; ?>
