List Parent and Children

    working on a site where the user wants a side menu “secondary navigation”

    What I need is to list the PARENT and the Children for the current page, even if it is a child and not the parent.

    So for instance I need something like

    PARENT
    child1
    child2
    child3

    That displays just like this even if you’re on Child3 page.

    Hope this makes sense.
    I looked up some stuff but I couldnt get it to work

    I tried this

    <?php
// Grab Correct Menu
if ($post->post_parent == 0):
	$menu_id = $post->ID;
	$menu_title = $post->post_title;
else:
	$menu_id = $post->post_parent;
	$parent = get_post($menu_id);
	$menu_title = $parent->post_title;
endif;

?>

    and

    <div class="secondnav">
<h3 class="secondHeader">
<a href="?page_id=<?php echo $menu_id; ?>">
<?php echo $menu_title; ?>
</a>
</h3>

<ul class="secondMenu">
<?php wp_list_pages('title_li=&child_of=' . $menu_id); ?>
</ul>
	</div>

    but I’m getting a list of all the pages.

    I tried this:

    List subpages even if on a subpage
The above examples will only show the children from the parent page, but not when actually on a child page. This code will show the child pages, and only the child pages, when on a parent or on one of the children.

This code will not work if placed after a widget block in the sidebar.

<?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) { ?>
  <ul>
  <?php echo $children; ?>
  </ul>
  <?php } ?>

    but it’s showing ALL of the parents and children and not just the current…

    Try example 3.

    By Example 3 you mean the third one under the link provided?

    It’s still printing all pages and children.

    Actually no – my example count was wrong. I meant this one:

    <?php
  if($post->post_parent) {
  $children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0");
  $titlenamer = get_the_title($post->post_parent);
  }

  else {
  $children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");
  $titlenamer = get_the_title($post->ID);
  }
  if ($children) { ?>

  <h2> <? echo $titlenamer ?> </h2>
  <ul>
  <?php echo $children; ?>
  </ul>

<?php } ?>

    I’ve also used the following function with some success:

    // Return page tree
	function theme_page_tree($this_page) {
		$pagelist = '';
		if( !$this_page->post_parent ) {
			$children = wp_list_pages('title_li=&child_of='.$this_page->ID.'&echo=0');
			if( $children ) {
				$pagelist .= '<li class="current_page_item"><a href="'.  get_page_link($this_page->ID) .'">' . $this_page->post_title . '</a>';
				$pagelist .= '<ul>' . $children . '</ul>';
				$pagelist .= '</li>';
			}
		}
		elseif( $this_page->ancestors ) {
			// get the top ID of this page. Page ids DESC so top level ID is the last one
			$ancestor = end($this_page->ancestors);
			$pagelist .= wp_list_pages('title_li=&include='.$ancestor.'&echo=0');
			$pagelist = str_replace('</li>', '', $pagelist);
			$pagelist .= '<ul>' . wp_list_pages('title_li=&child_of='.$ancestor.'&echo=0') .'</ul></li>';
		}
		return $pagelist;
	}

    called within the Loop using <?php if( function_exists ('theme_page_tree') echo theme_page_tree($post);?>

    <h2> <? echo $titlenamer ?> </h2> is working but the other half is listing all the pages still.

    Does it require the function?

    As for the function, where should I place this code? How should I place it?
    You lost me a bit on the “within the loop” bit.

    Sorry. Place the function in your theme’s functions.php file first.

    Next – where exactly do you want these sub-pages listed? Within the main page content or elsewhere?

    I’m placing it on the “Pages”.

    I’ve got sort of a custom layout I’m building where this rests on the side of all of the pages.

    Also, when I stated titlenamer was working, I actually was incorrect, it’s displaying the page title, not the title of the parent.

    What I need is a menu that looks like this no matter which child page you’re on:

    PARENT
    ____________
    CHILD
    CHILD
    CHILD
    CHILD

    Is that sub-page list within the page content/Loop? Or is it meant to be in the sidebar? The second option is going to be a bit more complicated.

    I’m using genesis framework theme and placing the code in “framework.php” because that is where the page layout is. It’s not a sidebar, more like a custom div spot (on the page) for this item.

    I don’t know Genesis, I’m afraid. If this block is inside the Loop, you should just be able to add if( function_exists ('theme_page_tree') echo theme_page_tree($post);. Otherwise, you’ll need to expand it a little to grab the current page id.

    How do I know if it’s “inside the loop?”

    See http://codex.wordpress.org/The_Loop for details of how to identify the Loop.

    It is NOT inside the loop, from what I’m understand.

    Bascially what I have is

    data being called up in a loop, then the page layout with css, then more data being called up.

    The part I’m dealing with is not inside of a loop.

    I tried all of the codes on the codex page and all of them just end up listing all of the pages. I’m not sure what is going on.
