   HI Rodolfo,
   I want to show an specific attribute in the single_product_summary after the price and on the left site. I know you told this in one of the courses but I can’t find the specific course anymore. Can you guide me in the right direction?

      Thanks for your question Marco 🙂

      So, to display a custom field you can use https://businessbloomer.com/woocommerce-show-number-products-sold-product-page/ (in this case it gets the total sales, but you can get the custom field value with get_post_meta() – here’s an example: https://businessbloomer.com/woocommerce-show-product-custom-field-in-the-category-pages/)

      Let me know

         Ciao Rodolfo,
         I am not getting there. The attribute is pa_merk and I want it after woocommerce_single_product_summary. I think it is easy but I am not seeing it. Could you …..:-)

         add_action( 'woocommerce_single_product_summary', 'merk_toevoegen', 10);
          function merk_toevoegen() {
            echo 'pa_merk';
         }

            Ah – sorry – so it’s a product attribute. Try with:

            global $product;
            echo $product->get_attribute( 'pa_merk' );

                  And if I want that attribute to link to the archive page?

                     I would search through the WooCommerce plugin files for the wc_display_product_attributes() function. At some stage within this function you find this for a single attribute:

                     $value_name = esc_html( $attribute_value->name );
                     if ( $attribute_taxonomy->attribute_public ) {
                     	$values[] = '<a href="' . esc_url( get_term_link( $attribute_value->term_id, $attribute->get_name() ) ) . '" rel="tag">' . $value_name . '</a>';
                     } else {
                     	$values[] = $value_name;
                     }
                     

                     So, you first need to get the $attribute_value.

                     Another option: https://docs.woocommerce.com/document/display-product-attribute-archive-links/

   Thank you – but I need to just add a number (Item Code) to be displayed – what should be the ‘data type’?

      You can just remove that line, as it’s not a price 🙂

   Hi Rodolfo,
   I have watched the lesson you have recommended and read the article, but something is still not clear;
   I have used this code – from your website – to add a custom field on variation products:

   // 1. Add custom field input @ Product Data > Variations > Single Variation
     
   add_action( 'woocommerce_variation_options_pricing', 'bbloomer_add_custom_field_to_variations', 10, 3 ); 
    
   function bbloomer_add_custom_field_to_variations( $loop, $variation_data, $variation ) {
   woocommerce_wp_text_input( array( 
   'id' => 'custom_field[' . $loop . ']', 
   'class' => 'short', 
   'label' => __( 'Item Code', 'woocommerce' ),
   'value' => get_post_meta( $variation->ID, 'custom_field', true )
   ) 
   );      
   }
     
   // -----------------------------------------
   // 2. Save custom field on product variation save
    
   add_action( 'woocommerce_save_product_variation', 'bbloomer_save_custom_field_variations', 10, 2 );
     
   function bbloomer_save_custom_field_variations( $variation_id, $i ) {
       $custom_field = $_POST['custom_field'][$i];
       if ( ! empty( $custom_field ) ) {
           update_post_meta( $variation_id, 'custom_field', esc_attr( $custom_field ) );
       } else delete_post_meta( $variation_id, 'custom_field' );
   }
     
   // -----------------------------------------
   // 3. Store custom field value into variation data
     
   add_filter( 'woocommerce_available_variation', 'bbloomer_add_custom_field_variation_data' );
    
   function bbloomer_add_custom_field_variation_data( $variations ) {
       $variations['custom_field'] = 'Item Code: ' . get_post_meta( $variations[ 'variation_id' ], 'custom_field', true ) . '';
       return $variations;
   }
   

   Can you let me know what changes I need to add to this code in order for the custom field to be displayed also on simple products pages?
   If it’s to much trouble – can you recommend a professional that can to it for money? I know it’s fairly easy for an experienced developer – I just need it solved fast and I am just in the
   beginning of my WooCommerce programming journey..

   Thank you!
