WordPress – List child pages but link them as an anchor

Sure thing:

This is for the navigation list on the page:

<?php
		if( is_page(155) ){
		    $args = array( 'child_of' => 155,
		                   'sort_column' => menu_order,
		                   'parent' => 155,
		                   'hierarchical' => 0
		                 );
		    $mypages = get_pages($args);
		?>
		<ul>
		    <?php foreach( $mypages as $page ) {
		?>
		   <li><a href="#<?php echo $page->post_name; ?>" class="smooth-scroll"><?php echo $page->post_title; ?></a></li>
		<?php
		    }
		 ?>
		 </ul>
		<?php
		}
		?>

And this is how I dumped out the images and added the anchor to them. You can see the ID for each title is the slug, and in the navigation at the top, each link echos the post/page name but with a # in front.

<?php $postslist = get_pages('number=9999&sort_order=ASC&sort_column=menu_order&child_of=155');
	foreach ($postslist as $post) :
	setup_postdata($post); ?>
	<ul class="main-projects-list">
	<?php

	$args = array(
	   'post_type' => 'attachment',
	   'numberposts' => -1,
	   'post_status' => null,
	   'post_parent' => $post->ID,
	   'orderby' => 'menu_order',
	   'order' => 'ASC',
	  );

	  $attachments = get_posts( $args );
	     $post_title = get_the_title($post->ID); // We get the post title
	     if ( $attachments ) {
	        foreach ( $attachments as $attachment ) {
	           $main_page_title = apply_filters( 'the_title', $post_title );
			   $img_title = apply_filters( 'the_title', $attachment->post_title );
			   $slug = basename(get_permalink());
	           echo '<li class="each-image">';
			   echo '<div class="each-exhibition-text">';
			   echo '<h1 id="';
			   echo $slug;
			   echo '">';
	    	   echo $main_page_title;
		       echo '</h1>';
			   echo the_content();
			   echo '</div>';
	           echo wp_get_attachment_image( $attachment->ID, 'large' , false, array('title' => $img_title));
	           echo '<p>';
	           echo $img_title;
	           echo '</p>';
	          }
	     }

	?>

	<?php endforeach; ?>

Hope this helps,
