我试着以一种更喜欢的方式重构代码，仅此而已。从逻辑上讲，这似乎是可行的。我所做的是：

我更喜欢WP_Query() 因为有经验的WordPress爱好者喜欢这样的自定义查询(We can learn more)get_template_directory_uri()wp_reset_postdata() 要重置查询，请执行以下操作WP_Query() 在该块中，新代码如下：

<div id="articles">
<?php $system_updates = new WP_Query( array(\'cat\'=>\'45\', \'posts_per_page\'=>\'1\') ); //Query for "System Updates" ?>
<?php if ($system_updates->have_posts()) : while ($system_updates->have_posts()) : $system_updates->the_post(); ?>
    <div class="unit one-of-three system-update">
        <article <?php post_class() ?> id="post-<?php the_ID(); ?>">

            <?php if ( has_post_thumbnail() ) { the_post_thumbnail(); } else { echo "<img src=\'" . get_template_directory_uri() . "/_/inc/images/system-update-small.png\' alt=\'Bosted System Update\'>"; } ?>

            <div class="description">
                <span class="date">System Update</span>
                <a href="<?php the_permalink() ?>"><h2><?php the_title(); ?></h2></a>
                <span class="date"><?php the_time(\'F j, Y\') ?></span>
            </div>

        </article>
    </div> <!-- .system-update -->
<?php endwhile; endif; wp_reset_postdata(); ?>

<?php $information = new WP_Query( array(\'cat\'=>\'1\', \'posts_per_page\'=>\'1\') ); //Query for "Information" ?>
<?php if ($information->have_posts()) : while ($information->have_posts()) : $information->the_post(); ?>
    <div class="unit one-of-three info">

        <article <?php post_class() ?> id="post-<?php the_ID(); ?>">

            <?php if ( has_post_thumbnail() ) { the_post_thumbnail(); } else { echo "<img src=\'" . get_template_directory_uri() . "/_/inc/images/information-small.jpg\' alt=\'Bosted System Information\'>"; } ?>

            <div class="description">
                <span class="date">Information</span>
                <a href="<?php the_permalink() ?>"><h2><?php the_title(); ?></h2></a>
                <span class="date"><?php the_time(\'F j, Y\') ?></span>
            </div>

        </article>
    </div> <!-- .info -->
<?php endwhile; endif; wp_reset_postdata(); ?>
</div> <!-- #articles -->

<?php the_post(); ?>
<div class=\'banner\'><?php if ( in_category(\'1\') ) { the_post_thumbnail(); } elseif ( in_category(\'45\') ) { echo "<img alt=\'Bosted System Update\' class=\'system-update\' src=\'" . get_template_directory_uri() . "/_/inc/images/system-update-big.png\'/>"; } else { echo "<img class=\'system-update\' alt=\'Bosted Information\' src=\'" . get_template_directory_uri() . "/_/inc/images/information-big.jpg\'/>"; } ?></div>
