List top-level page's children ALWAYS

Hi,

I am trying to create a sub-menu on certain pages that lists the top-level parent's pages on all of it's children pages.

I have it working, but only to the second level. I need it to work on the third level as well though. Below is the code I am using:



<?php

	if($post->post_parent){

		$children = wp_list_pages('title_li=&child_of='.$post->post_parent.'&echo=0');

	} else{

		$children = wp_list_pages('title_li=&child_of='.$post->ID.'&echo=0');

	}

	if ($children) { ?>

        		

                <h2><?php

			$parent_title = get_the_title($post->post_parent);

			echo $parent_title;

		?></h2>

        	

		<ul>

		<?php echo $children; ?>

		</ul>

			

	<?php } 

?>

Here are the pages I am currently working on:
- [Parent]
-- [Child]
--- [Grandchild] - Sub-menu displaying the wrong children. Should be displaying same menu as parent and child.

Try this:



<?php

	global $wp_query;

	if( empty($wp_query->post->post_parent) ) {

	$parent = $wp_query->post->ID;

	} else {

	$parent = $wp_query->post->post_parent;

	} ?>

	<?php if(wp_list_pages("title_li=&child_of=$parent&echo=0" )): ?>

	<?php wp_list_pages("title_li=&child_of=$parent" ); ?>

	<?php endif; ?>

This link to the WordPress function reference should help you further as well.

I've also tried



?php 

	if(!$post->post_parent){

	// will display the subpages of this top level page

		$children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");

	}else{

	// diplays only the subpages of parent level

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

					

	if($post->ancestors)

	{

		$ancestors = end($post->ancestors);

		$children = wp_list_pages("title_li=&child_of=".$ancestors."&echo=0");

	}

				

	if ($children) { ?>

		<ul>

		       <?php echo $children; ?>

		</ul>

	<?php } ?>

But it will only display children on the parent pages. What is weird about this, is the above code worked on my development site, then I moved things over to a media temple sever and it stopped working.

You need to see if the $post->post_parent has childrens. The code below should do the trick.

<?php

	if($post->post_parent){

		//get the parrent and see if it'a a top page (has no parent)

		$parent = get_page($post->post_parent);

		if($parent->post_parent){ //if it's not a top page, then his parent should be

			$children = wp_list_pages('title_li=&child_of='.$parent->post_parent.'&echo=0');

		}else{

			$children = wp_list_pages('title_li=&child_of='.$post->post_parent.'&echo=0');

		}

	} else{

		$children = wp_list_pages('title_li=&child_of='.$post->ID.'&echo=0');\

	}



	if ($children) { ?>

                <h2><?php

			$parent_title = get_the_title($post->post_parent);

			echo $parent_title;

		?></h2>



		<ul>

		<?php echo $children; ?>

		</ul>



	<?php } 

?>

That did the trick!

One last thing, it displays the correct pages, but on the grandchild page, the header (parent_title) changes to the child page's title. Is there anyway to make that title always stay as the top-level page's title?

Thanks!

Sure. The code below should work as you expect. Though it's a bit clumsy. Give me a minute and I'll make it much better :)

<?php

	if($post->post_parent){

		//get the parrent and see if it'a a top page (has no parent)

		$parent = get_page($post->post_parent);

		if($parent->post_parent){ //if it's not a top page, then his parent should be

			$children = wp_list_pages('title_li=&child_of='.$parent->post_parent.'&echo=0');

		}else{

			$children = wp_list_pages('title_li=&child_of='.$post->post_parent.'&echo=0');

		}

	} else{

		$children = wp_list_pages('title_li=&child_of='.$post->ID.'&echo=0');

	}



	if ($children) { ?>

            

			<h2><?php

			if($parent->post_parent){

				$parent_title = get_the_title($parent->post_parent);

			}else{

				$parent_title = get_the_title($post->post_parent);

			}

			echo $parent_title;

		?></h2>



		<ul>

		<?php echo $children; ?>

		</ul>

<?php } ?>

Ok, this is it:

<?php

	if($post->post_parent){

		$parent = get_page($post->post_parent);

		$first_level=($parent->post_parent)?$parent->post_parent:$post->post_parent;

	}else{

		$first_level = $post->ID;

	}

	if(wp_list_pages("title_li=&child_of=$first_level&echo=0" )){

		<h2><?php echo get_the_title($first_level); ?></h2>

		<ul><?php wp_list_pages("title_li=&child_of=$first_level" ); ?></ul>

	<?php } ?>
