【问题描述】：
好的，我还有一小段代码正在努力解决。我正在构建一个有条件的侧边栏。目标是仅在查看“博客”类别中的帖子时显示与博客相关的内容。我已经完成了部分工作，但我试图将类别的 RSS 提要引入侧边栏中以显示为最近的帖子的部分。它不起作用，因为我是一个 php 新手，我不完全确定为什么。非常感谢任何建议或指示。我会先发布问题部分，然后再发布整个 php 文件，这样大家就可以看到我遇到问题的部分的上下文。
问题部分：
echo '<div class="panel iq-news">';
echo '<h4><span><a href="/category/blog/feed"><img src="/wp-content/themes/iq/images/rss-icon.gif" alt="Subscribe to our feed"/></a></span>IQNavigator Blog</h4>';
<?php
query_posts('category_name=Blog&showposts=2');
if (have_posts()) : ?>
echo '<ul>';
<?php while (have_posts()) : the_post(); ?>
echo '<li><a href="<?php the_permalink();?>"><?php the_title();?> </a></li>';
<?php endwhile;?>
echo '</ul>';
<?php endif;?>
echo '<div class="twitter">';
echo '<p id="twitter-updates">';
<?php twitter_updates();?>
echo '</p>';
echo '<p class="text-center"><a href="http://twitter.com/iqnavigator">Follow us on twitter</a></p>';
echo '</div>';
echo '</div>';
整个该死的长声明，出于上下文原因：
