Show posts after grandchild level

Posted 23 April 2014 - 01:00 PM

Hi all

I'm not sure if I should be posting this here or in the PHP board so please forgive me if I am using the wrong board but I am stuck on a script and out of pure desperation looking for some guidance.

I am trying to build a script that will display and organise posts in their different levels of categories. The script I am working on works perfectly except when I click on the grandchild category it shows an empty div instead of the posts associated with the child category. And this is my problem, I don't know how to make my script show posts once the grandchild is clicked.

Category structure:
Parent category (category ID is 1)
- Child category
-- Grandchild category
--- Post associated with child category

*The code contains an extra function (add random featured image from the post to parent and child category as thumbnails), I mention this in case it confuses anyone.

elseif (is_page(31))/* products */ {
	$taxonomyName = "category";
	$catparent = 1;
		if ($_GET) {
		if (array_key_exists('cat', $_GET)) {
			$catparent = $_GET['cat']; }}
				if (empty($catparent) || !is_numeric($catparent)) {
					$catparent = 1;
			$terms = get_terms($taxonomyName,array('parent' => $catparent,'hierarchical'=>false));
				foreach($terms as $term) {
					$RANDfeaturedImage = $term->slug;
				global $wp_query;

					'orderby' => 'rand',
					'posts_per_page' => 1,
					'post_type' => 'post',
					'hide_empty' => 0,
					'tax_query' => array(
							'taxonomy' => 'category', 
							'field' => 'slug', 
							'terms' =>  $RANDfeaturedImage,
							'class'	=> 'img-block',
				$new_query = null;
				$new_query = new WP_Query($args);
				while ($new_query->have_posts()) : $new_query->the_post();
					echo '<div class="boxlet"><a class="img-block" href="?cat='.$term->term_id.'">';
						the_post_thumbnail('medium', array( 'class' => "img-block"));
					echo '</a><a class="view" href="?cat='.$term->term_id.'">'.$term->name.'</a></div>'; 

I have looked at a number of different shopping cart and catalogue plugins but they either don't work as desired or have limitations in other ways. By doing it this way I can avoid using a plugin and all products can be loaded and controlled under posts.

I would really appreciate it if someone can assist me with this. (I can PM a link to the live example of the script if need be)
