wp_nav_menu – Sub-navigation based on page

Hi,

I’m currently building a website for the first time using WordPress. I’m very novice with PHP and do this just as a hobby. I’ve gotten stuck trying to work out the new wp_nav_menu.

This is my WIP here: http://srv02.anthonylawrence.me.uk/scottD/wordpress/

If you go onto a page, eg http://srv02.anthonylawrence.me.uk/scottD/wordpress/fife-airport/ I have added a sub navigation to the left sidebar. There are 5 of these different navigations, one for ‘Fife Airport’ and its children, ‘For Pilots’ and its children etc.

I am currently using this script

<h1>Sub-navigation</h1>
<div id="sidepanel">
	<?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 class="subnav">
  		<?php echo $children; ?>
  		</ul>
  <?php }  ?>
</div>

I’ve searched everywhere and have been Googling for the past 2 hours for a solution to this for wp_nav_menu. I’ve already created my custom menus in the admin panel, just need a way for only showing the menu for that page.

The reason I’m wanting to use wp_nav_menu instead is so I can customise the titles of the pages to be different from the link text.

Any solutions much appreciated.
