Variations Sku not showing up WordPress/woocommerce

2 Views

I have set up a woocommerce store and I add some variations to some products. Each variation has its own sku number, but for some reason they are not showing up on the products overview panel. Is there any way were I can add them or somebody could show me the right direction to go.
Also, if I try to search the variation, is not showing up the product were is located. Do I have to register the variation sku somewere? Is this comming by default with woocommerce or not?

Thanks!

  1. Ok given that nobody came with an aswer I had to dig a little bit myself 😀
    So here is the solution that I found for the moment.

    On file class-wc-admin-post-types.php which is located on woocommerce/includes/admin

    You have to modify some code on line 277

    case 'sku' :

    $type = (get_class($the_product));

    if( $type == 'WC_Product_Variable' ){

        $available_variations = $the_product->get_available_variations();

        echo '<strong> Variations: </strong>' . count($available_variations) . '<br><br>';

        for ($i = 0; $i <  count($available_variations); $i++ ) {

            echo ($available_variations[$i]['sku']) . '<br>';
        }
    }
    else {
        echo $the_product->get_sku() ? $the_product->get_sku() : '<span class="na">&ndash;</span>';
    }
break;

    And now you can get something like this:
    When you have variations on your product you will show the amount of variations and all of the available sku’s and if is not a variable product you will only show the sku.

    Now I’m thinking that I will probably modify also the stock colum and show the amount of stock on each one of them.

    Hope this helps someone else. And thanks for the ones who tried to help!

    Ok… so I added the support for stock nothing much different than then previous code… So on the same document now on line 344, you can add this.

    case 'is_in_stock' :

            $type = (get_class($the_product));

            if( $type == 'WC_Product_Variable' ){

                $available_variations = $the_product->get_available_variations();

                echo '<strong> Variations stock: </strong> <br><br>';

                for ($i = 0; $i <  count($available_variations); $i++ ) {


                    if ( $available_variations[$i]['is_in_stock'] == 0 ) {
                        echo '<mark class="outofstock">' . __( 'Out of stock', 'woocommerce' ) . '</mark>';
                    }else {

                        echo '<mark class="instock">' . __( 'In stock', 'woocommerce' ) . '</mark>';

                    }
                    if ($available_variations[$i]['variation_is_active']) {
                        echo ' &times; ' . $available_variations[$i]['max_qty'] . '<br>' ;
                    }
                }
            } else {

                if ( $the_product->is_in_stock() ) {
                    echo '<mark class="instock">' . __( 'In stock', 'woocommerce' ) . '</mark>';
                } else {
                    echo '<mark class="outofstock">' . __( 'Out of stock', 'woocommerce' ) . '</mark>';
                }

                if ( $the_product->managing_stock() ) {
                    echo ' &times; ' . $the_product->get_total_stock() ;

                }
            }
            break;

    An you get something like this:

    Resume: this approach can have some performance problems… carefull on how many product variations do you have.

    https://github.com/woothemes/woocommerce/issues/9396

  2. add_action( 'woocommerce_single_product_summary', 'dev_designs_show_sku', 5 );
function dev_designs_show_sku(){
    global $product;

    if ( $product->is_type( 'variable' ) ) {
      $available_variations = $product->get_available_variations();
      for ($i = 0; $i <  count($available_variations); $i++ ) {    
          echo 'SKU: ' . ($available_variations[$i]['sku']) . '<br>';
      }
    } else {
      echo 'SKU: ' . $product->get_sku();
    }
}

  3. Just remove the IF conditional check that surround the HTML out of the SKU from the meta.php file. Around LINE 18.

    The file is in the WC plugins/templates folder.

    OR

    Just from this -> $product->get_sku() From the IF statement as that is causing the issue.

    It returns an empty string is why the IF conditional is never satisfied.

    In addition, the reason why this happens is if the parent product does not have a SKU, and only your variables have, this issue will occur. Hence my comment up top stating it returns empty string as it tries to pull from the parent first. another words if you have set SKU to the parent and variables, everything will work even without modification of the code I mentioned.
