Displaying a read more link after excerpt, with Autonav

Here is an example AutoNav filter that will display a “Read More” link, for posts in a list.

We invoke this as follows:

[autonav display="posts,list,title,nothumb,excerpt" count=5 postid="category:autonav-plugin" class="readmore"]

• Selecting attachments by tag
• AutoNav and Attachment Taxonomy Support
• Listing categories with AutoNav

  Let's explore how we can use the AutoNav plugin for WordPress to display some posts from a category.

• More AutoNav filters

Put this code in your theme’s functions.php:

function autonav_excerpt_readmore($html, $class, $pic, $attr) {
  if ($attr['display'] == 'posts' && $attr['class'] == 'readmore') {
    if (strlen($pic['excerpt'])) {
      $html .= '<a href="' . $pic['permalink'] . '">' . __('Read more') . '...</a>';
    }
  }
  return $html;
}

add_filter('autonav_create_list_item', 'autonav_excerpt_readmore', 
   50, 4);

The filter is added with priority 50, so it will be inserted after the excerpt. The function only inserts the “Read More” link if the class="readmore" parameter is used in the AutoNav invocation, and only if posts are listed, and only if the post actually had an excerpt.

NOTE: The above was originally asked here.
