Get product category (Woocommerce) with a taxonomy field to filter the loop

Hi!

Currently, I am working on a website where I have to show posts with the category that is selected with the taxonomy field. With “normal” (single) posts, it works like a charm. To show how it works:

<?php
        // get the current taxonomy term
        $term = get_queried_object();

        $catact = get_field('actueel_category', $term);

        $loop = new WP_Query( array(
            'post_type' => 'actueel',
            'posts_per_page' => 2,
            'category__in' => $catact,
          )
        );
        ?>
        <?php while ( $loop->have_posts() ) : $loop->the_post(); ?>

          <a href="<?php the_permalink();?>">

            <div class="post">

              <?php $thumb = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full' );?>
              <div class="thumbnail" style="background-image:url('<?php echo $thumb['0'];?>');">
              </div>

              <div class="theme__inner__content">
                <h4><?php the_title();?></h4>
                <span class="more">lees meer</span>
              </div>

            </div>

          </a>

      <?php endwhile; wp_reset_query(); ?>

Now, when I try to do the same with Woocommerce Products, it doesn’t work. Here is the code I use for that:

<?php
      // get the current taxonomy term
      $term = get_queried_object();

      $catpro = get_field('product_category', $term);

        $loop = new WP_Query( array(
            'post_type' => 'product',
            'posts_per_page' => 2,
            'product_cat' => $catpro,
          )
        );
        ?>
        <?php while ( $loop->have_posts() ) : $loop->the_post(); ?>

          <a href="<?php the_permalink();?>">

            <div class="post">

              <?php $thumb = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full' );?>
              <div class="thumbnail" style="background-image:url('<?php echo $thumb['0'];?>');">
              </div>

              <div class="theme__inner__content">
                <h4><?php the_title();?></h4>
                <span class="more">lees meer</span>
              </div>

            </div>

          </a>

      <?php endwhile; wp_reset_query(); ?>

Is there something that I’m not getting?

In the Admin area: I use the taxonomy field, both outputs are being displayed as Term ID’s. For the regular post I’ve selected the “category” taxonomy and for the product the “product_cat” taxonomy.

Can someone think with me here? I can’t seem to solve it. Maybe I’m overlooking something.

Thanks in advance!

In your first example you are using the category__in argument which can only be used with the category taxonomy.

In WooCommerce the product category taxonomy is a custom taxonomy. Since it is a custom taxonomy instead of using category__in in your second example you should use a tax_query. Take a look at the tax_query documentation for wp_query, it is pretty intuitive to set up if you are not familiar with it.

Hope this is helpful!
