Not compatible with Apple Pay

Resolved

(@saddev)

I use the Classic Checkout but this plugin is not compatible with the Apple Pay feature offered by this plugin https://woocommerce.com/products/woocommerce-paypal-payments/

For example I have an Additional Field with type=select but even if the option is selected it say that field is required.

It works fine with Google Pay.

See the system report from WooCommerce:

Hi,

Thank you very much for the detailed explanation and for sharing the system report. We truly appreciate the time and effort you took to investigate the issue and provide all the relevant details.

Currently, due to Apple Pay testing limitations on our end, we are unable to fully reproduce the exact scenario in our local environment. However, after reviewing the details you shared, our team has prepared a custom code snippet that should help resolve the issue with the required select field validation during Apple Pay checkout.

Please test the following code by adding it to your active theme’s functions.php file or via a Code Snippets plugin on your staging site:
```
/**
 * fix: WooCommerce Checkout Field Editor + PPCP Apple Pay
 */
add_filter( 'woocommerce_checkout_fields', 'thwcfd_unset_required_for_apple_pay', 1001 );
function thwcfd_unset_required_for_apple_pay( $fields ) {
    $funding_source = isset( $_POST['funding_source'] )
        ? strtolower( sanitize_text_field( wp_unslash( $_POST['funding_source'] ) ) )
        : '';

    $express_sources = apply_filters( 'thwcfd_express_checkout_funding_sources', array( 'applepay' ) );

    if ( empty( $funding_source ) || ! in_array( $funding_source, $express_sources, true ) ) {
        return $fields;
    }

    foreach ( $fields as $fieldset_key => &$fieldset ) {
        if ( ! is_array( $fieldset ) ) {
            continue;
        }
        foreach ( $fieldset as $key => &$field ) {
            // Only touch plugin-managed custom fields, not core WooCommerce fields.
            if ( ! empty( $field['custom'] ) && ! empty( $field['required'] ) ) {
                $field['required'] = false;
            }
        }
    }

    return $fields;
}
```
If you continue to face any issues after applying the code, please let us know by opening a support ticket and we will be happy to assist you further.

Thank you!

This not work the problem is in the /?wc-ajax=ppc-validate-checkout request it doesn’t reach the order creation . For a whatever reason the PayPal Payments for WooCommerce not validate the custom fields correctly but only for Apple..

@elenathemehigh this can be closed. The issue is not related to your plugin but to PayPal Payments for WooCommerce due to Apple Merchant Validation. Thank you!
