I have a custom field to select a category (custom taxonomy) and then I will display a list of all of its child-categories. This works fine when I return the custom field as "term_id."

HOWEVER. I would like to also get the slug from this selected category (the parent) so I can link to its category page (I don't think I can link to it with the ID). So I thought maybe I should return the custom field as an object instead. This is what it dumps:

 stdClass Object ( [term_id] => 122 [name] => Quick Release Watch Bands [slug] => fits-all [term_group] => 0 [avhec_term_order] => 0 [term_taxonomy_id] => 122 [taxonomy] => product_cat [description] => Watch bands in many colors [parent] => 0 [count] => 293 [meta_id] => 1 [woocommerce_term_id] => 122 [meta_key] => order [meta_value] => 22 ) 

Do you know how I can pull out both the ID (122) and the slug (fits-all) from this? Here is my code so far. The custom field is called "selected_category".

<?php $catid = get_sub_field('selected_category');  

            $args = array(
              'taxonomy'     => 'product_cat',
              'orderby'      => 'name',
              'show_count'   => 0,
              'pad_counts'   => 0,
              'hierarchical' => 1,
              'title_li'     => '',
              'depth'        => 1,
              'child_of'     => $catid


<h4><a href="URL.COM/NEED-CATEGORY SLUG"><?php the_sub_field('title'); ?></a></h4>

<ul class="subcats">
<?php wp_list_categories( $args ); ?>

Can anyone help me, please? Thank you so much!

  • This is a Pure PHP question. Look into basic PHP object syntax. – s_ha_dum Apr 12 '13 at 14:23
  • Wordpress offers a "get_term_by()" function -- so I wasn't sure if that would be the solution. But I can't seem to figure it out. I will try to see what I can learn from that link. Thank you! – LBF Apr 12 '13 at 14:35
  • $thisisanarray['thisisanarraykey'] = 'this will be its value' – Tom J Nowell Apr 12 '13 at 15:01
  • $thisisanobject->this_is_a_variable_inside_that_object = "this is now its value" – Tom J Nowell Apr 12 '13 at 15:02
  • Thank you for the help. I think I may have been making this harder than it needed to be. I haven't solved it, but I think I'm going to delete this question and pose it a new way using wp_list_categories to link to the parent too. – LBF Apr 12 '13 at 15:04

It sounds like you're looking for the get_term_link() function.

Your code will look something like this:

$catid = get_sub_field('selected_category');

$term_link = get_term_link( intval( $catid ), 'product_cat' );

<h4><a href="<?php echo esc_url( $term_link ); ?>"><?php the_sub_field('title'); ?></a></h4>

As you can see, get_term_link() takes two argument, the term and taxonomy. If you're saving the term object in the field and passing it as the first argument, then the second argument is optional. If you pass the ID, as done above, then you have to pass the taxonomy name.

  • YES!! That's exactly what I needed. Thank you so much, mrweb. I really appreciate it. – LBF Apr 12 '13 at 15:31
