category page with snippet data and “offer”

Hi, thanks! This code is almost the same as the one I have. And it doesn’t add anything to the Color Page: mysite.com/colour/white

This is what I have in my color page schema:

{"@type":"CollectionPage","@id":"https://mysite.com/colour/white/#webpage","url":"https://mysite.com/colour/white/","name":"White","isPartOf":{"@id":"https://mysite.com/#website"},"inLanguage":"en"}

And I’d like to add products with offer to this schema.

Hi, thanks for the clarification. Can you please provide the filter to be added in my functions.php that can add color to the product schema in my individual product pages? Right now, I have a pa_colour which is added as an additional property, but I want to include that inside the product schema. I have tried to add a filter but it doesn’t change anything in the output. Can you check what the problem is?

add_filter('rank_math/json_ld', function($data, $jsonld) {
    if (!is_product()) {
        return $data;
    }

    $product_id = get_the_ID();
    $product = wc_get_product($product_id);

    if (!$product) {
        error_log('Product not found for ID: ' . $product_id);
        return $data;
    }

    $colors = wc_get_product_terms($product_id, 'pa_colour', array('fields' => 'names'));
    $color_string = implode(', ', $colors);

    $materials = wc_get_product_terms($product_id, 'pa_pile-material', array('fields' => 'names'));
    $material_string = implode(', ', $materials);

    $thickness = $product->get_attribute('pa_thickness');
    $origin = $product->get_attribute('pa_origin');
    $weight = $product->get_attribute('pa_weight');

    if (isset($data['@graph']) && is_array($data['@graph'])) {
        foreach ($data['@graph'] as &$item) {
            if ($item['@type'] === 'Product') {
                // Add color directly to the Product schema
                $item['color'] = $color_string;

                // Add material to the Product schema
                if (!empty($material_string)) {
                    $item['material'] = $material_string;
                }

                // Add depth (thickness)
                if (!empty($thickness)) {
                    $item['depth'] = [
                        "@type" => "QuantitativeValue",
                        "unitCode" => "MMT",
                        "value" => $thickness
                    ];
                }

                // Add countryOfOrigin
                if (!empty($origin)) {
                    $item['countryOfOrigin'] = $origin;
                }

                // Add weight
                if (!empty($weight)) {
                    $item['weight'] = [
                        "@type" => "QuantitativeValue",
                        "unitCode" => "KGM",
                        "value" => $weight
                    ];
                }

                // Update priceValidUntil if it exists
                if (isset($item['offers']) && is_array($item['offers'])) {
                    $item['offers']['priceValidUntil'] = date('Y-m-d', strtotime('+1 year'));
                }

                // Ensure image is set
                if (!isset($item['image']) || empty($item['image'])) {
                    $image_id = $product->get_image_id();
                    $image_url = wp_get_attachment_image_url($image_id, 'full');
                    if ($image_url) {
                        $item['image'] = $image_url;
                    }
                }

                // Remove additionalProperty
                if (isset($item['additionalProperty'])) {
                    unset($item['additionalProperty']);
                }

                break;
            }
        }
    }

    return $data;
}, 99999, 2);

My products are simple (one product per post), therefore I didn’t use the woocommerce color property, but added it manually with attribute pa_colour. Can you check why the code I provided doesn’t apply to my page? I added the link in the sensitive data section. Please don’t include my sitename in the discussion.

Thanks! This works. Now I want to remove certain parts of the markup added by rank math. What’s the rank math filter for giving priority to those? For example, I want to remove the additionalProperty, or assign correct values to height and width.
