这是代码：

<?php
/**
 * Template Name: Voice Page (Two Columns)
 * @package WordPress
 * @subpackage Twenty_Ten
 * @since Twenty Ten 1.0
 */

get_header(); ?>


<?php breadcrumb(); ?>

<?php // this is the main loop ?>
<?php if(have_posts()) : while(have_posts()) : the_post(); ?>

<div class="top-column">

    <div class="post">

        <h2 class="post-title">
            <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a>
        </h2>

        <div class="entry">
            <?php the_content(); ?>
        </div>

        <div class="post-meta-data">
            <?php wp_link_pages('before=<p>'.__('Pages:','options').'&after=</p>'); ?>
        </div>

    </div>

    <?php endwhile; ?>

<?php else: ?>

    <p><?php _e('Sorry, no posts matched your criteria.','options'); ?></p>

<?php endif; ?>

</div><!-- .top-column -->

<div class="left-column">

<?php // retrieve a list of posts with category Voice Audio Demos
$args = array('category_name' => 'Voice Page (Left Column)', 'order' => 'DESC', 'posts_per_page'=>-1);
$customposts = get_posts($args);
foreach($customposts as $post) : setup_postdata($post); ?>

    <div class="post">

        <h2 class="post-title">
            <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a>
        </h2>

        <div class="entry">
            <?php the_content(); ?>
        </div>

    </div>

<?php endforeach; ?>

</div><!-- .left-column -->

<div class="right-column">

<?php // retrieve a list of posts with category Voice Audio Demos
$args = array('category_name' => 'Voice Page (Right Column)', 'orderby' => 'DESC', 'posts_per_page'=>-1);
$customposts = get_posts($args);
foreach($customposts as $post) : setup_postdata($post); ?>

    <div class="post">

        <h2 class="post-title">
            <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a>
        </h2>

        <div class="entry">
            <?php the_content(); ?>
        </div>

    </div>

<?php endforeach; ?>

</div><!-- .left-column -->

<?php get_footer(); ?>

它只是检索类别语音页面 (左列) 和语音页面 (右列) 的帖子。我在这个类别中超过 5 个帖子 bu 页面只显示 5：

最佳解决方案

如果你看看 get_posts documentation on Codex，你可以看到你想显示的帖子数量有一个参数：

$numberposts (integer) (optional) Number of posts to return. Set to 0 to use the max number of posts per page. Set to -1 to remove the limit.

Default: 5

这就是为什么它只显示 5 个帖子。您需要将参数添加到 args 数组中：

$args = array(
    'category_name' => 'Voice Page (Right Column)',
    'orderby' => 'DESC',
    'posts_per_page'=>-1,
    'numberposts'=>-1
);
