    I got this to show 2 levels deep of subpages of the current page. But I need to check if there is any in the result before displaying. I have other things that get displayed that I dont want to show next to the list if there isn’t any pages in the list. Will I just have to write my own query to get a count and echo nesting loop? I like the nesting of the list items.

    <ul id="nav-subpages" role="navigation">
		<?php wp_list_pages('child_of='.$post->ID.'&title_li=&depth=2'); ?>
		</ul>

  • Try:

    <?php $my_pages = wp_list_pages('child_of='.$post->ID.'&title_li=&depth=2&echo=0');
if( $my_pages ) : ?>
<ul id="nav-subpages" role="navigation">
<?php wp_list_pages('child_of='.$post->ID.'&title_li=&depth=2'); ?>
</ul>
<?php endif;?>

    That worked. I’m having issue trying to get the before_widget before_title stuff to echo. When wp_list_pages is uncommented the before and after widget, title stuff doesn’t echo, but the $subpages and everything else does. My if($subpages!="") works but is commented for testing this issue now.
    It worked fine when wp_list_pages had echo=1 within the widget.

    EDIT: I fixed it. I had 'echo=0' instead of '&echo=0'

    function widget($args, $instance) {
	extract($args);
	$title = esc_attr(strip_tags($instance['title']));
	$depth = intval($instance['depth']);

	global $post;
	$tmp_post = $post;
	//$subpages = wp_list_pages('child_of='.$post->ID.'&title_li=&depth='.$instance['depth'].'echo=0');

	//if($subpages!=""){

		echo $before_widget.$before_title;

		if($instance['title'] == "%current%"){
			echo $post->post_title;
		}else{
			echo trim($instance['title']);
		}

		echo $after_title;
		?>

		<ul id="nav-subpages" role="navigation">
		<?php echo $subpages; ?>
		</ul>

		<?php
		echo $after_widget;
	//}
	$post = $tmp_post;
}
