In my wordpress enviroment, I have a number of pages, and I also have a custom post type called casestudy. I have setup a page-clients.php that has some of it's own content on, I then use the query_posts() function to pull in all the posts with the post type casestudy.

When viewing a single case study I wanting to show a nav, this nav needs to contain the links to pages, clients, and case study and underneath case studies I want to add all the posts that are of the custom post type 'casestudy' so far I have following,

<?php wp_list_pages(array('include' => '154, 136', 'title_li' => '', 'sort_column' => 'ID', 'sort_order' => 'DESC', 'depth' => '1')); ?>

How can I lists all the casestudy posts also, can it be done with wp_list_pages()

The wp_list_pages() function uses get_pages(), which accepts a post_type argument-array key, so you can use that same argument array key in `wp_list_pages():

wp_list_pages( array(
    'post_type' => 'casestudy'
) );

Unfortunately, it looks like the post_type value must be a string, rather than an array (that is, if I'm reading the source correctly); which means that wp_list_pages() can only handle one post-type at a time. If you need to list all in one menu, you could try concatenating them:


$pagelist = wp_list_pages( array( 
    'include' => '154, 136', 
    'title_li' => '', 
    'sort_column' => 'ID', 
    'sort_order' => 'DESC', 
    'depth' => '1'
    'echo' => false
) );

$casestudylist = wp_list_pages( array(
    'post_type' => 'casestudy',
    'title_li' => '',
    'echo' => false
) );

$concatenatedlist = $pageslist . $casestudylist;

<?php echo $concatenatedlist;

  • Did you copy/paste the code? Check for a syntax error, that I've since corrected. I left off the comma after 'post_type' => 'casestudy' in the argument array. Commented Jul 26, 2011 at 16:39
  • @Chip Bennett, thanks for the code and explanation. Is there another way to display wp pages and Custom Post Types together that are added dynamically (meaning that I don't know their name)? Maybe there is another function that can handle it instead of wp_list_pages? Thanks!
