[iBlogPro 4.2.4] Hide the title of grandchildnav widget if no children?

[onokazugmailcom 0]

The grandchildnav widget on the sidebar displays the h3 title even when there is no child pages to display. It would be nice to have an option to automatically/manually hide the widget if no content to display. iBlogPro 4.2.4

Hi Onokazu - Do you have a link to your site? We may be able to come up with a solution in the meantime.

My site is on my local PC so I cannot show it to you right now. However, I managed to fix the problem by modifying library/_grandchildnav.php. Here is the content of modified and cleaned up version of the file: ` <?php if (!isset($post) || is_search()) return; if (property_exists($post, 'ancestors')) { $ancestors_array = $post->ancestors; } else { $ancestors_array = array(); } if (($post->post_parent && wp_list_pages("title_li=&child_of=".$post->ID."&echo=0")) || count($ancestors_array) >= 2 ) { if (count($ancestors_array)==1) { $subnavpost = get_post($post->ID); $children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0&sort_column=menu_order"); }else{ $reverse_ancestors = array_reverse($ancestors_array); $subnavpost = get_post($reverse_ancestors[1]); $children = wp_list_pages("title_li=&child_of=".$reverse_ancestors[1]."&echo=0&sort_column=menu_order"); } if ($children) { ?>

<?php echo $subnavpost->post_title;?>

• <?php echo $children;?>

<?php } } `

I think I now know why I have this problem only on certain pages. It's because my custom plugin is excluding several leaf pages using the wp_list_pages_excludes WordPress filter. Those pages will not display but the original code of _grandchildnav.php thinks that those hidden pages exist in the list of pages fetched with the wp_list_pages function. I know not many plugins use the filter to exclude pages from being displayed, but it would be nice if the fix be included in the future versions of iBlogPro.
