Get related products SKUs in WooCommerce


We want to show a section called "complete the look" in WooCommerce. We are using PureClarity to do that.

PureClarity asked us to extend the WooCommerce feed by adding a code snippet in functions.php to add related peoducts SKUs under RelatedProducts.

We used the following code:

function product_callbackk($data, $product) {
        $data['RelatedProducts'] =  $product->get_sku() ?? null;
    return $data;
}
add_filter( 'pureclarity_feed_get_product_data', 'product_callbackk', 10, 2 );

But it showing only the current product SKU and not the related products SKUs. Any advice?


Solution

  • I don't use PureClarity so I added an example based on a default hook in WooCommerce.

    In this I use wc_get_related_products() which allow to obtain related products based on the current product ID.

    The product SKU per product can then be obtained via a foreach loop.

    So you get:

    function action_woocommerce_single_product_summary() {
        // Get the global product object
        global $product;
        
        // Is a WC product
        if ( is_a( $product, 'WC_Product' ) ) {
            // Initialize
            $skus = array();
    
            // Get product ID
            $product_id = $product->get_id();
            
            // Get related products based on product category and tags || second argument = limit of results, default = 5
            $related_products = wc_get_related_products( $product_id, 10 );
    
            // Loop through
            foreach ( $related_products as $related_product ) {
                // Get product 
                $product = wc_get_product( $related_product );
    
                // Get product SKU
                $product_sku = $product->get_sku();
    
                // NOT empty
                if ( ! empty( $product_sku ) ) {
                    // Push to array
                    $skus[] = $product_sku;
                }
            }
    
            // Output
            echo '<pre>', print_r( $skus, 1 ), '</pre>';     
        }
    }
    add_action( 'woocommerce_single_product_summary', 'action_woocommerce_single_product_summary', 10 );
    

    Or in your specific case:

    /**
     * @param mixed[] $data - the array of data that will be sent to PureClarity
     * @param WC_Product $product - the WooCommerce product object
     * @return mixed
     */
    function filter_pureclarity_feed_get_product_data( $data, $product ) {
        // Is a WC product
        if ( is_a( $product, 'WC_Product' ) ) {
            // Initialize
            $skus = array();
    
            // Get product ID
            $product_id = $product->get_id();
            
            // Get related products based on product category and tags || second argument = limit of results, default = 5
            $related_products = wc_get_related_products( $product_id, 10 );
    
            // Loop through
            foreach ( $related_products as $related_product ) {
                // Get product 
                $product = wc_get_product( $related_product );
    
                // Get product SKU
                $product_sku = $product->get_sku();
    
                // NOT empty
                if ( ! empty( $product_sku ) ) {
                    // Push to array
                    $skus[] = $product_sku;
                }
            }
    
            $data['RelatedProducts'] = $skus;
        }
    
        return $data;
    }
    add_filter( 'pureclarity_feed_get_product_data', 'filter_pureclarity_feed_get_product_data', 10, 2 );
