Display specific categories in list form – working code example provided

(@jayseventwo)

Hi guys, i have the code below which displays all my categories and sub categories in list form, which works perfectly for what i want, but i would like to be able to choose a specific category to choose instead of them all – can this be done? (instead of showing all product_cat, show product_cat = “outdoors” )

if ( is_front_page() ) {

function get_product_terms( $term_id ) {

		$html = '';

		$args = array( 'hide_empty' => 0, 'parent' => $term_id );

		$terms = get_terms('product_cat', $args);

		foreach ($terms as $term) {

			$html .= '<li';

			if( $term_id == 0 ) {

				$html .= ' class="top_li"';

			}

			$html .= '><a href="'.get_term_link($term->slug, 'product_cat').'">' . $term->name . '</a>';	

			if( $list = get_product_terms( $term->term_id )) {

				$html .= '<ul class="second_level">'.$list.'</ul>';

			}

			$html .= '</li>';

		}

		return $html;

	}

	if( $list = get_product_terms( 0 )) {

		echo '<ul id="top_ul">'.$list.'</ul><div style="clear:both;">';

	}

  global $post;

}

Thanks in advance for any help.

Just to clarify, you are looking to list all subcategories of a specific category? If so, then this function is already setup to do just that. SImply call this function and insert the term_id for the “outdoors” in the args for that function.

For instance, if your “outdoors” category has a term_id of “3” your call to this function would look like this:

<?php get_product_terms( 3 ); ?>

It seems like the code you have listed here is setup to only run on the front page, so if you might want to copy this function and paste it with a different function name somewhere in your functions file so you can use it elsewhere.

Thanks for your reply. I only wanted it to display on the front page, but your idea is much better. Unfortunately, i have added it to my functions.php and am getting this error:

Catchable fatal error: Object of class WP_Error could not be converted to string in /home/jayseven/public_html/woo/wp-content/themes/jayseventwo/lib/custom.php on line 22

Line 22 is:
$html .= '><a href="'.get_term_link($term->slug, 'product_cat').'">' . $term->name . '</a>';

Any ideas?

Also, would the category id also be the tag_id, as i cannot actually see that category id anywhere?

I will keep on trying to resolve this issue, but if you have any ideas that would be great. Thanks.
