Displaying small excerpts from latest posts
If you want to display the latest posts on your WordPress blog, but only the content which comes before the
<!--more-->tag, you can use this:<ul> $post = get_post(); $myposts = get_posts( array( 'posts_per_page' => 5 ) ); foreach( $myposts as $post ) : setup_postdata( $post ); $content_arr = get_extended ( $post->post_content ); ?> <li> <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a> </br> <?php echo $content_arr['main']; // Display the part before the more tag ?> </li> <?php endforeach; ?> </ul>Expand full source codeCollapse full source code
Note:
$content_arr['extended']contains the contents after the more tag.
