Exclude Pages from List

Use the exclude parameter hide certain Pages from the list to be generated by wp_list_pages. Excluding a Page will also exclude all of its sub-pages from the list to be generated.

The last time this worked was in WordPress 2.3.3. Sadly, it is still not working in WordPress 2.6.1.

To fix this bug, you will need to replace the wp_list_pages function with the one in WordPress 2.3.3. Open the file “post-template.php” in the “wp-includes” folder with your favourite text/html editor.

Copy the following code:

function wp_list_pages($args = '') {
$defaults = array(
'depth' => 0, 'show_date' => '',
'date_format' => get_option('date_format'),
'child_of' => 0, 'exclude' => '',
'title_li' => __('Pages'), 'echo' => 1,
'authors' => '', 'sort_column' => 'menu_order, post_title'
);
$r = wp_parse_args( $args, $defaults );
extract( $r, EXTR_SKIP );
$output = '';
$current_page = 0;
// sanitize, mostly to keep spaces out
$r['exclude'] = preg_replace('[^0-9,]', '', $r['exclude']);
// Allow plugins to filter an array of excluded pages
$r['exclude'] = implode(',', apply_filters('wp_list_pages_excludes', explode(',', $r['exclude'])));
// Query pages.
$pages = get_pages($r);
if ( !empty($pages) ) {
if ( $r['title_li'] )
$output .= '<li class="pagenav">' . $r['title_li'] . '<ul>';
global $wp_query;
if ( is_page() )
$current_page = $wp_query->get_queried_object_id();
$output .= walk_page_tree($pages, $r['depth'], $current_page, $r);
if ( $r['title_li'] )
$output .= '</ul></li>';
}
$output = apply_filters('wp_list_pages', $output);
if ( $r['echo'] )
echo $output;
else
return $output;
}

Replace the entire area of the code of the existing wp_list_pages function, which looks something like “wp_list_pages($args = ”) { blah blah blah }“. Once you have done this, your WordPress pages will display sub pages and exclude certain pages correctly.
