customising wp_list_pages

Forgive me for saying so but IMHO this is an exceptionally interesting question and one which is of wide application. It is also similar to one I asked a while ago and received no answer to. Without hijacking the thread but to put more meat on it I would love to know where the widgets are defined, including get pages, and where the functions in the widgets are set up. Where I am really headed is that I would like functions (a) to return plain unadorned links and (b) to have the option of adding my markup like the OP. In my case I would like to add an IE conditional at the critical point. I hope someone can point us in the right direction.

Try using wp_list_pages to get your list of pages. This example will assign all page titles to the $pages array.

$pages = wp_list_pages('depth=-1&echo=1&hierarchical=0&sort_column=post_title&title_li=');
`

@root
The widget code is in wp-includes/widgets.php and does make use of the template tag, wp_list_pages()

If fact, dstn could use the code from widgets.php as an example also.

Hi MichealH,

Thanks for replying, how do i get the link to the pages. I know that i could just use <?php echo $pages ?> to give me the list of pages, but how do i get the link to those pages.

Thanks

Daniel

<?php
$pages = wp_list_pages('depth=-1&echo=1&hierarchical=0&sort_column=post_title&title_li=');
if ( ! empty($pages) ) {
foreach ($pages as $page) {
echo $page;
}
}
?>

is one possibility.

Sorry i may be a bit stupid, but i just don’t see how this would work. This would just produce the same thing as wp_list_pages, how do i get the links and page titles from it?

e.g. i need to have <li><a href="link"><span>page name</span></a></li>

Could i use echo $page[‘title’]?

Thanks

Daniel

There’s this also:

<?php
$querystr = "SELECT $wpdb->posts.* FROM $wpdb->posts WHERE $wpdb->posts.post_status = 'publish' AND $wpdb->posts.post_type = 'page' ORDER BY $wpdb->posts.post_title ASC";
$pageposts = $wpdb->get_results($querystr, OBJECT);
?>
<?php if ($pageposts): ?>
<?php foreach ($pageposts as $post): ?>
<?php setup_postdata($post); ?>
<p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></p>
<?php endforeach; ?>
<?php else : ?>
Not Found
<?php endif; ?>

Thanks great thanks! ??

You wouldn’t happen to know how i could tell which page i am on so i could change the class accordingly?

Thanks

Daniel

Try using a Conditional Tag

Mh. Thanks a lot this is really useful. But are you sure they are still in widgets.php? I can’t find them. I thought maybe widgets.php called in the actual widgets from another file. Maybe?

Yes, wp-includes/widgets.php is where the built-in widgets are defined. Just look for the wp_list_pages text in that file for example.

Also, there is some widget ‘data’ kept in wp_options with an option_name like widget_pages.

That is great thanks. I am going to get right on this.

I wanted to do this too, and couldn’t find any information on it.

In the end, I had to edit the start_el() function in wp-includes/classes.php

Change the following (from about line 517):
$output .= $indent . '<li class="' . $css_class . '"><a href="' . get_page_link($page->ID) . '" title="' . attribute_escape(apply_filters('the_title', $page->post_title)) . '">' . apply_filters('the_title', $page->post_title) . '</a>';

To this:
$output .= $indent . '<li class="' . $css_class . '"><a href="' . get_page_link($page->ID) . '" title="' . attribute_escape(apply_filters('the_title', $page->post_title)) . '"><span>' . apply_filters('the_title', $page->post_title) . '</span></a>';

Of course, this will always add span tags any time wp_list_pages is called. And you’ll have to remember that you’ve done this hack the next time you upgrade…

Eureka. The Holy Grail. A big up to analogpanda for his discovery of where that dang thing is edited. Now we are rocking. Is this the end for Son of Suckerfish? ??

Just for completeness, my above hack was done with WP 2.2.1

Let’s hope that 2.3 (or even 2.2.2?) has a little more flexibility in this regard.

I’m actually a little surprised they wouldn’t just use “the loop” – would probably end up with a more elegant solution than my hacky method… But I’m not a real php dev – maybe they have their reasons!
