Now I have a strange problem:

1) One of my pages lists itself as a subpage. I can click and click and click and the page stays the same. phpMyadmin reveals that there actually is NO real subpage anywhere, so there’s nothing to correct in the database.

2) One of my pages lists the subpages list, but it is empty.
So maybe it is “” or ” ” or something… That page actually has a child – but it is an attachment.

Code from this plugin:

// First it seems to change $current_page to parent?
// Goes to top of page hierarchy???
while($current_page) {
$page_query = $wpdb->get_row(“SELECT ID, post_title, post_parent FROM $wpdb->posts WHERE ID = ‘$current_page’”);
$current_page = $page_query->post_parent;
}

$parent_id = $page_query->ID;
$parent_title = $page_query->post_title;
// Only display the message if there are actually subpages
if($wpdb->get_results(“SELECT * FROM $wpdb->posts WHERE post_parent = ‘$parent_id’”)) {
echo’< div id=”subpage” > < ul >< li >Subpages: < /li >’;
$html = wp_list_pages(“child_of=$parent_id&depth=$depth&echo=”.(!$return).”&title_li=0″);
echo’< /ul >< /div >’;
}

There is a bug in the conditional statement.

When a page has an ATTACHMENT, the SELECT * FROM statement returns true, and the Subpages header is displayed. wp_list_pages does not list attachments, though. –> Header and empty row. This happens in WordPress 2.0.7.

Page type = attachment should be excluded.

Better yet, include ONLY 1) “pages”, 2) that are “published”. Can I see an incompatibility with WP2.1 here in the present code? WP2.1 uses two fields now to describe the type and status of the record.

The other problem, subpage being subpage of itself, is not yet resolved.

My lament can be found here, too: http://wordpress.org/support/topic/106065

BTW, one of the things I want to do with this is create an “Acknowledgements” page to list all the plug-ins and widgets I’m using, with “reviews” of each. I’m using a couple of yours, and they’re great!

I’ve used your nice plugin for some time.
But it seemed to stop working with the latest WP version.
So I upgraded to the latest plugin version.
But inserting the [subpages /] tag (without the brackets) on http://game-research.com/index.php/articles/ I get all pages on the site, and not the subpages of the “Articles” page.

Any ideas?

Thanks.

echo list_subpages('order=post_title');

Having said that, it’s still useful to add that line to prevent the plugin from throwing an error if no sort query is passed.

if (!$order) { $order='post_title'; }

It should go before line 47, which looks like this:

if ( $subpages > 0 ) {

Hope that helps!

Awesome plugin, btw. Exactly what I was looking for.

WordPress database error: [You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'ASC' at line 1]
SELECT * FROM wp_posts WHERE post_status = ‘static’ ORDER BY ASC

<?php list_subpages(); ?>

to this:

<?php list_subpages(0); ?>

That’ll echo it without the need to modify the code.
