[resolved] Custom Page Links (7 posts)

    I have a page where I list all child pages. That works fine.

    When I click a link and am taken to a page I would like to have a prev / next link to the the prev and next pages that were listed on the initial page. These are NOT posts.

    How would I go about that. I thought I could just add "1" to the current pages ID but the ID's are all over the show and randomly numbered it seems.

    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.

    Thanks I will give that a go... not too sure what this piece means though... 'page_id=nn'

    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>';
    }
