I'm trying to display the title and excerpt of the most recent 8 posts on the sidebar.

I'm getting a list where:

  • All items link to the oldest post
  • All titles are "id number of a post that should be displayed"+"oldest post title"
  • All excerpts are from the oldest post

<?php
        $args = array( 'numberposts' => '8' );
        $recent_posts = wp_get_recent_posts( $args );
        $noticias_highlight = true;

        foreach( $recent_posts as $recent ){ 
?>
                    <div class="entry <?php if ($noticias_highlight) echo 'highlight'; $noticias_highlight = !$noticias_highlight; ?>">
                        <div class="title"><p><a href="<?php the_permalink($recent["ID"]); ?>"><?php the_title($recent["ID"]); ?></a></p></div>
                        <div class="subtitle"><?php the_excerpt($recent["ID"]); ?></div>
                    </div>
<?php
        } 
?>

Don't use the 'helper' methods, they tend to cause more trouble than they're worth.

Any time you want to grab posts, be it the latest, the oldest, in a category etc, use a WP_Query loop, here is its standard form:

$query = new WP_Query( $args );
if ( $query->have_posts() ) {
    while ( $query->have_posts() ) {
        $query->the_post();
        // do stuff
    }
    wp_reset_postdata();
} else {
    // none were found
}

This is what wp_recent_posts will be doing internally, although it isn't doing it very well. So save the above to an autocomplete macro in your editor

Many mistakes in the question's code:

  • the_permalink() takes no arguments and returns the link of the current post. Use echo get_permalink() instead.
  • the_title() prints the title of the current post, and its first argument is a string to be printed before the title. That's what causing the titles to be all the same but containt the numeric IDs for the correct posts. Use echo get_the_title() instead.
  • the_excerpt() takes no arguments and prints the excerpt of the current post. I don't know if there's a similar function that accepts he post ID as an argument.

Most importantly:

  • wp_get_recent_posts() will return an array containing one array for each post (hence the foreach). So instead of the_title() or get_the_title() the title can be returned via $array[post_title], the excerpt via $array[post_excerpt] (will be empty if no excerpt is present, won't automatically truncate the post content), $array[post_content] for the post content, etc.
  • wp_get_recent_posts() doesn't seem to use a wordpress loop. So functions that use the current post will always use the same post. That's what happens in the example.

And even most importantly:

You can use the Display Posts shortcode in your sidebar markup. The plugin is here: http://wordpress.org/plugins/display-posts-shortcode/

    I prefer not using a plugin for simple functionality that can be achieved in a few lines of code. – That Brazilian Guy Aug 12 '13 at 18:12

    Not everyone who reads wordpress.stackoverflow lives in the PHP code. Some folks are just interested in getting things done. Why penalize alternate solutions? – dthorpe Aug 12 '13 at 18:21
