cat 链接的循环不循环 WordPress 网站

Question

我有这段代码，所有变量都已加入，但最新消息没有显示。有什么想法吗？

<div class="content">
    <?php get_sidebar('field'); ?>
    <?php
    global $current_user;
    get_currentuserinfo();
    $user_info = get_userdata($current_user->ID);

    if ( have_posts() && $user_info->user_level != 0) : while ( have_posts() ) : the_post(); ?>

    <?php // get custom fields
    $wt_email = get_post_meta($post->ID, 'wt_email', true);
    $wt_feed = get_post_meta($post->ID, 'wt_website', true);
    $wt_facebook = get_post_meta($post->ID, 'wt_facebook', true);
    $wt_twitter = get_post_meta($post->ID, 'wt_twitter', true);
    $wt_linkedin = get_post_meta($post->ID, 'wt_linkedin', true);
    ?>

    <div class="entry">
    <h1><?php the_title(); ?></h1>
    <div class="body">
    <?php the_content(); ?>
    </div>
    <div class="share">
        <div class="links">
            <h3>Links</h3>
            <ul>
                <?php if($wt_twitter) { ?><li><a href="http://<?php print $wt_twitter; ?>">Twitter</a></li><?php } ?>
                <?php if($wt_facebook) { ?><li><a href="http://<?php print $wt_facebook; ?>">Facebook</a></li><?php } ?>

            </ul>
            </div>
<?php endwhile; // End the loop. Whew. ?>
        <div class="news">

                if( $loop->have_posts() ) : while ( $loop->have_posts() ) : $loop->the_post();
                    echo '<li><a href="' . the_permalink() . '">';
                        the_title(); 
                    echo '</a></li>';
                endwhile;
                endif;

虽然不是确切的答案，但您是否尝试添加：

error_reporting(E_ALL);
ini_set('display_errors', '1');

在页面顶部，以显示可能发生的任何错误？
