Display a short summary of the latest article
If you want to show the latest posts on your WordPress site but only display the content before the <!--more--> tag, you can output it like this:
<ul>
<?php
global $post;
$args = array( 'numberposts' => 5 );
$myposts = get_posts( $args );
foreach( $myposts as $post ) : setup_postdata( $post );
$content_arr = get_extended (get_the_content() ); ?>
<li>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
</br>
<?php echo $content_arr['main']; //显示more标签之前的内容 ?>
</li>
<?php endforeach; ?>
</ul>Note: $content_arr['extended'] contains the content after the more tag.
