大家好，我想问下，如何把调用文章列表改成调用所有分类的最新文章摘要
我的代码如下：
<div class="title"><a href="<?php echo get_option('home'); ?>#" class="active">Products</a></div>
<?php if (have_posts()) : ?>
<?php query_posts('cat=7&showposts=20'); ?>
<ul class="newslist">
<?php while (have_posts()) : the_post(); ?>
<li id="post-<?php the_ID(); ?>">
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a>
</li>
<?php endwhile; ?>
</ul>
<?php else : ?>
<h2 class="center">Not Found</h2>
<p class="center">Sorry, but you are looking for something that isn't here.</p>
<?php include (TEMPLATEPATH . "/searchform.php"); ?>
<?php endif; ?>
</div>
谢谢啊，帮忙解决一下哈
