Custom Page Links

This is a little convoluted, and there may be an easier answer. I am assuming that you use wp_list_pages() to list the child pages.

In the loop in the child template, use a call to wp_list_pages similar to this:

$pagelist = wp_list_pages("title_li=&echo=0&child_of=$post->post_parent");

After the loop, explode $pagelist on ‘<li ‘. Search the resulting array for the current ‘page_id=nn’. Use the entry before for the previous page, and the entry after for the next page.

You will need to find the entry that corresponds to the current page by searching for ‘page_id=nn’ where ‘nn’ is the current page_id.

These lines go in the Loop to save the page ID and the child page list:

$current_page = $post->ID;
$pagelist = wp_list_pages("title_li=&child_of=$post->post_parent&echo=0");

Here is a sample of how you could use the saved values after the Loop:

$pagearray = explode('<li ',$pagelist);
$junk = array_shift($pagearray); // First entry is empty
for ($i=0;$i<sizeof($pagearray);++$i) {
   if (strpos($pagearray[$i],"$current_page")) {
     break;
   }
}
if ($i < sizeof($pagearray)) {
   echo '<p>';
   // $i points to current page entry in $pagearray
   if ($i > 0) {  // Is there a previous entry?
     $prevlink = $pagearray[$i - 1];
     $prevlink = preg_replace('/^.+<a/','<a',$prevlink);
     $prevlink = preg_replace('/<\/li>$/','',$prevlink);
     echo "&laquo; $prevlink";
   }
   if ($i < (sizeof($pagearray) - 1)) {  // Is there a next entry?
     $nextlink = $pagearray[$i + 1];
     $nextlink = preg_replace('/^.+<a/','<a',$nextlink);
     $nextlink = preg_replace('/<\/li>$/','',$nextlink);
     echo "&nbsp&nbsp&nbsp $nextlink &raquo;";
   }
   echo '</p>';
}
