Taxonomy sub categories

  • I’m using the taxonomy field to display categories from WooCommerce. I’d like to show the sub categories of the displayed category but unable to get these displaying automatically in a list below.

    
    <?php 
    
    global $post;
    
    $terms = get_field('product_range_categories');
    
    if( $terms ): ?>
    
    	<ul>
    
    	<?php foreach( $terms as $term ): ?>
    
    		<li>
    			<div>
    				<a href="<?php echo get_term_link( $term ); ?>">
    					<h2>
    						<?php echo $term->name; ?>
    					</h2>
    
    					<?php 
    
    					$thumbnail = get_field('category_thumbnail', $term );
    					 
    					if( !empty($thumbnail) ): ?>
    					 
    						<img src="<?php echo $thumbnail['sizes']['featured']; ?>" alt="<?php echo $thumbnail['alt']; ?>" />
    
    						<?php  ?>
    					 
    					<?php endif; ?>
    
    					<?php if( $term ) {
    						foreach($term as $t) {
    							$t = get_category($t);
    							echo $t->name;
    						}
    					} ?>
    				</a>
    
    				
    				
    				<a href="<?php echo get_term_link( $term ); ?>">View the full range</a>
    
    			</div>
    		</li>
    
    	<?php endforeach; ?>
    
    	</ul>
    
    <?php endif; ?>
    

    The smaller loop inside sort of pulls a category from the parent that has sub categories, but it’s the post categories and not for WooCommerce

    
    <?php if( $term ) {
    	foreach($term as $t) {
    		$t = get_category($t);
    		echo $t->name;
    	}
    } ?>
    

    Any help would be awesome. Thanks.

  • Hi @jordantrainor

    The inner loop you have highlighted won’t work as expected.
    The variable $term is an object, not an array of sub terms.

    To get the children of a term, you need to use some code like so:
    http://codex.wordpress.org/Function_Reference/get_term_children

    That function will allow you to load the child terms and then you can loop over them.
