我有一个代码显示最近3次更新的页面或帖子。

当我将此代码添加到主题提要栏时，它工作得非常好。php文件。

<?php
 $today = current_time(\'mysql\', 1);
 $count = 3;
 if ( $recentposts = $wpdb->get_results("SELECT ID, post_title FROM $wpdb- 
 >posts WHERE post_status = \'publish\' AND (post_type = \'page\' OR post_type = 
 \'post\') AND post_modified_gmt < \'$today\' ORDER BY post_modified_gmt DESC 
 LIMIT $count")):
 ?>
 <h4><?php _e("Recent Updates"); ?></h4>
 <ul>
 <?php
 foreach ($recentposts as $post) {
 if ($post->post_title == \'\') $post->post_title = sprintf(__(\'Post #%s\'), 
 $post->ID);
 echo "<li><a href=\'".get_permalink($post->ID)."\'>";
 the_title();
 echo \'</a></li>\';
  }
  ?>
</ul>
<?php endif; ?>

但当我在主题函数上添加此代码时。php文件，并使用woody片段php代码在小部件中调用它。然后，它只显示当前页面作为最近更新的页面3次。以下是功能代码：

function iq_recent_update(){
 global $wpdb;
 $today = current_time(\'mysql\', 1);
 $count = 3;
 if ( $recentposts = $wpdb->get_results("SELECT ID, post_title FROM $wpdb- 
 >posts WHERE post_status = \'publish\' AND (post_type = \'page\' OR post_type = 
 \'post\') AND post_modified_gmt < \'$today\' ORDER BY post_modified_gmt DESC 
 LIMIT $count")):
 ?>
 <h4><?php _e("Recent Updates"); ?></h4>
 <ul>
 <?php
 foreach ($recentposts as $post) {
 if ($post->post_title == \'\') $post->post_title = sprintf(__(\'Post #%s\'), 
 $post->ID);
 echo "<li><a href=\'".get_permalink($post->ID)."\'>";
 the_title();
 echo \'</a></li>\';
  }
  ?>
</ul>
<?php endif; 
}

在woody php代码片段中，我将其称为

<?php iq_recent_update(); ?>

它只显示当前页面名称。为什么工作方式不同？我如何解决？

非常感谢。

/* Recent updated post & pages */
if ( ! function_exists( \'iq_recent_update\' ) ) :
function iq_recent_update() {
$orig_post = $post;
global $post;
$args=array(
        \'posts_per_page\' => 3,  
        \'orderby\'          => \'modified\',
        \'order\'            => \'DESC\',
        \'post_type\'        => array(\'post\', \'page\'),
         \'post_status\' => \'publish\'
);

$my_query = new wp_query( $args );
if( $my_query->have_posts() ) {

echo \'<h3>Recent updates</h3>\';
        echo "<ul>";
while( $my_query->have_posts() ) {
$my_query->the_post();?>
<li><a href="<? the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a></li>
<?php
}
}
echo "</ul>";
$post = $orig_post;
wp_reset_query();
}
endif;
