Missing field hasMerchantReturnPolicy ❗DOESNT WORK FOR VARIABLE PRODUCTS

Hello,

We apologize for the issue you are facing with the hasMerchantReturnPolicy field not working for variable products. To ensure that the return policy is applied to variable products as well, you need to modify the filter to include the logic for variants.

Here’s an example of how you can adjust your code to handle variable products:

add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
    if ( empty( $data['richSnippet'] ) || ! in_array( $data['richSnippet']['@type'], [ 'Product', 'ProductGroup' ] ) ) {
        return $data;
    }

    // Add Merchant Return Policy
    $data['hasMerchantReturnPolicy'] = [
        '@context' => 'https://schema.org/',
        '@type' => 'MerchantReturnPolicy',
        'applicableCountry' => 'US',
        'returnPolicyCategory' => 'https://schema.org/MerchantReturnFiniteReturnWindow',
        'merchantReturnDays' => 30,
        'returnMethod' => 'https://schema.org/ReturnByMail',
        'returnFees' => 'https://schema.org/FreeReturn'
    ];

    // For variable products
    if ( 'Product' ===  $data['richSnippet']['@type'] ) {
        $data['richSnippet']['offers']['hasMerchantReturnPolicy'] = ['@id' => '#merchant_policy'];
        return $data;
    }

    if ( empty( $data['richSnippet']['hasVariant'] ) ) {
        return $data;
    }

    foreach ( $data['richSnippet']['hasVariant'] as $key => $value ) {
        if ( empty( $value['offers'] ) ) {
            continue;
        }
        $data['richSnippet']['hasVariant'][ $key ]['offers']['hasMerchantReturnPolicy'] = [ '@id' => '#merchant_policy' ];
    }

    return $data;
}, 99, 2);

This code snippet ensures that the hasMerchantReturnPolicy is included for both simple and variable products. You can customize the values as needed for your store.

Hello,

Thank you for your query and we are so sorry about the trouble this must have caused.

Please try the following code instead:

add_filter('rank_math/json_ld', function ($data, $jsonld) {
	if (empty($data['richSnippet']) || ! in_array($data['richSnippet']['@type'], ['Product', 'ProductGroup'])) {
		return $data;
	}

	$data['shippingDetails'] = [
		'@context'     => 'https://schema.org/',
		'@type'        => 'OfferShippingDetails',
		'@id'          => '#shipping_policy',
		'deliveryTime' => [
			'@type'        => 'ShippingDeliveryTime',
			'handlingTime' => [
				'@type'    => 'QuantitativeValue',
				'minValue' => 0,
				'maxValue' => 1,
				'unitCode' => 'DAY',
			],
			'transitTime' => [
				'@type'    => 'QuantitativeValue',
				'minValue' => 1,
				'maxValue' => 5,
				'unitCode' => 'DAY'
			],
		],
		'shippingRate' => [
			'@type'    => 'MonetaryAmount',
			'value'    => 5,
			'currency' => 'USD',
		],
		'shippingDestination' => [
			'@type' => 'DefinedRegion',
			'addressCountry' => 'US'
		]
	];

	$data['hasMerchantReturnPolicy'] = [
		'@context'     => 'https://schema.org/',
		'@type'        => 'MerchantReturnPolicy',
		'@id'          => '#merchant_policy',
		'applicableCountry' => 'US',
		'returnPolicyCategory' => 'https://schema.org/MerchantReturnFiniteReturnWindow',
		'merchantReturnDays' => 30,
		'returnMethod' => 'https://schema.org/ReturnByMail',
		'returnFees' => 'https://schema.org/FreeReturn'
	];
	
	if ('Product' ===  $data['richSnippet']['@type']) {
		$data['richSnippet']['offers']['shippingDetails'] = ['@id' => '#shipping_policy'];
		$data['richSnippet']['offers']['hasMerchantReturnPolicy'] = ['@id' => '#merchant_policy'];
		return $data;
	}

	if (empty($data['richSnippet']['hasVariant'])) {
		return $data;
	}

	foreach ($data['richSnippet']['hasVariant'] as $key => $value) {
		if (empty($value['offers'])) {
			continue;
		}

		$data['richSnippet']['hasVariant'][$key]['offers']['shippingDetails'] = ['@id' => '#shipping_policy'];
		$data['richSnippet']['hasVariant'][$key]['offers']['hasMerchantReturnPolicy'] = ['@id' => '#merchant_policy'];
		$data['richSnippet']['hasVariant'][$key]['offers']['priceCurrency'] = 'IRT';
	}

	return $data;
}, 99, 2);

Let us know how that goes.

Looking forward to helping you.
