这应该可以完成工作。它将检查是否有贴有当前页面标题的帖子。没有必要使用if (have_posts()): 在页面模板上：如果调用模板，将是因为有帖子：）
<div class="page-loop">
<?php
while (have_posts()) : the_post();
$page_title = strtolower(get_the_title());
the_title(\'<h1>\',\'</h1>\');
?>
<p><?php the_content(); ?><p>
<?php endwhile;?>
</div>
<!-- Get the most recent post that has been tagged with the page title -->
<div class="related-posts">
<?php
$args = array(
\'tag\' => $page_title,
\'posts_per_page\' => 1,
);
$query = new WP_Query($args);
if ($query->have_posts()) :
while ($query->have_posts()) : $query->the_post();
the_title(\'<h1>\',\'</h1>\');
?>
<p><?php the_content(); ?><p>
<?php endwhile; else: ?>
<p>Sorry, no posts with this tag!</p>
<?php endif; wp_reset_query(); ?>
</div>
如果您希望使用自定义元将“标记”添加到页面中（而不仅仅是使用标题），您可以向页面中添加自定义元框，如下所示。将以下代码添加到函数中。php（注意：这将向所有页面添加元框）
/** register the meta box */
function my_theme_add_meta_boxes() {
global $post;
add_meta_box(
\'my-theme-meta\',
\'Choose a tag\',
\'my_theme_print_page_meta\',
\'page\',
\'normal\',
\'high\'
);
}
add_action(\'add_meta_boxes\', \'my_theme_add_meta_boxes\');
/** Add extra meta to the page */
function my_theme_print_page_meta() {
global $post;
$page_tags = get_post_meta($post->ID, \'_page-tags\', true);
?>
<label for="page-tags">Add a \'tag\'</label>
<input type="text" class="page-tags" name="page-tags" value="<?php echo esc_attr($page_tags); ?>" />
<?php
}
/** Save post meta */
function my_theme_save_custom_meta() {
global $post;
// Stops WP from clearing post meta when autosaving
if( defined(\'DOING_AUTOSAVE\') && DOING_AUTOSAVE ) {
return $post->ID;
}
if (isset($_POST[\'page-tags\'])) {
$clean = sanitize_text_field($_POST[\'page-tags\']);
update_post_meta($post->ID, \'_page-tags\', $clean);
}
}
add_action(\'save_post\', \'my_theme_save_custom_meta\');
然后是您的页面。php代码可能如下所示：
<div class="page-loop">
<?php
while (have_posts()) : the_post();
$page_tags = get_post_meta($post->ID, \'_page-tags\', true);
the_title(\'<h1>\',\'</h1>\');
?>
<p><?php the_content(); ?><p>
<?php endwhile;?>
</div>
<?php if ($page_tags): ?>
<!-- Get the most recent post that has been tagged with the page title -->
<div class="related-posts">
<?php
$args = array(
\'tag\' => $page_tags,
\'posts_per_page\' => 1,
);
$query = new WP_Query($args);
if ($query->have_posts()) :
while ($query->have_posts()) : $query->the_post();
the_title(\'<h1>\',\'</h1>\');
?>
<p><?php the_content(); ?><p>
<?php endwhile; else: ?>
<p>Sorry, no posts with this tag!</p>
<?php endif; wp_reset_query(); ?>
</div>
<?php endif; // There are \'page tags\' ?>
