Woocommerce的获取父类别

Question

我正在尝试获取带有woocommerce类别图像的父类别标题，我只获得了一个特定类别，可以说我只想获得类别ID和类别ID'18'或类别块'demo'的图像，我能够仅通过以下代码即可获得我对子类别的要求

<?php

                $catTerms = get_terms('product_cat', array(
                    'hide_empty' => 0, 
                    'orderby' => 'ASC', 
                    'child_of'=>'17' 
                ));
                foreach($catTerms as $catTerm) : 
                $term_link = get_term_link( $prod_cat, 'product_cat' );

                ?>
                <?php $thumbnail_id = get_woocommerce_term_meta( $catTerm->term_id, 'thumbnail_id', true ); 

                // get the image URL
                $image = wp_get_attachment_url( $thumbnail_id ); 
                $term_link = get_term_link( $catTerm, 'product_cat' );
                ?>

                <div class="col-md-4">
                    <a href="<?php echo $term_link ?>">
                        <div class="bling-wrapper">
                            <div class="bling-image">
                             <img src="<?php echo $image; ?>" />
                            <div class="shop-bling">
                                shop Now
                            </div>
                            </div>
                            <div class="bling-title">
                                <h3><?php echo $catTerm->name; ?></h3>
                            </div>

                        </div>
                     </a>
                </div>

                <?php endforeach; ?>

但是我想通过ID或Slug（带有标题和图像）显示父类别而没有子类别，我该如何实现这一目标....
