Get ACF field value from product attribute on WooCommerce single product page

I have made a field to add to the WooCommerce attributes. I have added a picture below for more clearance. I am trying to display the field on the single product page. I have added the following code to the content-single-product.php template file. $terms = get_the_terms( $product->id, 'pa_merk'); var_dump($terms); $image = get_field('afbeelding_merk', $terms->taxonomy . '_' . $terms->slug); // Display the image if it exists if ($image) { echo '<img src="' . $image . '" />'; } else { echo "Foto niet gevonden."; } What am I doing wrong? I tried multiple ways to retrieve the terms taxonomy and slug. But on multiple ways it says NULL. I have tried searching on the internet and asking chatgpt. I have also tried to change the part "$terms->slug" to "$terms->term_id", but that did not help either.

Updated: There are mistakes in your code. Try the following instead: $product_id = $product->get_id(); // get the product ID $taxonomy = 'pa_merk'; $terms = wp_get_post_terms( $product_id, $taxonomy ); // get the product terms if ( ! is_wp_error($terms) && ! empty($terms) ) { $term = reset($terms); // get the first WP_Term object $image = get_field('afbeelding_merk', $taxonomy . '_' . $term->term_id); // Display the image if it exists if ( ! empty($image) ) { echo '<img src="'.isset($image['url']) ? $image['url'] : $image.'" />'; } else { echo "Foto niet gevonden."; } } else { echo "Foto niet gevonden."; } Or the shorter WooCommerce version: $taxonomy = 'pa_merk'; $term_name = $product->get_attribute($taxonomy); // get attribute term name if ( ! empty($term_name) ) { $term = get_term_by('name', $term_name, $taxonomy); $image = get_field('afbeelding_merk', $taxonomy . '_' . $term->term_id); // Display the image if it exists if ( ! empty($image) ) { $image = ; echo '<img src="'.isset($image['url']) ? $image['url'] : $image.'" />'; } else { echo "Foto niet gevonden."; } } else { echo "Foto niet gevonden."; } Both should work

According to provided code, to implement required functionality to display ACF plugin custom field of type "image", with return format as "Image Array" in woocommerce template file "content-single-product.php", the following code can be used. $image = ''; $terms = get_the_terms( $product->id, 'pa_merk'); if(!is_wp_error($terms) && !empty($terms)) { foreach($terms as $term) { $image = get_field('afbeelding_merk', $term->taxonomy . '_' . $term->term_id); if($image) { break; } } } if (isset($image['url'])) { echo '<img src="'.$image['url'].'" />'; } else { echo "Foto niet gevonden."; } If return format of ACF plugin custom field of type "image" is "Image URL", then, in above code, this line of code: if (isset($image['url'])) { echo '<img src="'. $image['url']. '" />'; } should be replaced with this line of code: if ($image) { echo '<img src="'. $image. '" />'; } It can be checked, if this code works.
