如果邮政编码超出 WooCommerce 中的区域，则阻止结帐

Answer 1

为了防止客户在 WooCommerce 中完成结帐，我们的想法是连接 WooCommerce 的结帐验证系统，并在邮政编码超出您的送货区域时停止结帐过程。

add_action('woocommerce_after_checkout_validation', 'validate_postcode_before_checkout');

function validate_postcode_before_checkout($posted) {
    // Get the billing postcode from the checkout form
    $postcode = isset($posted['billing_postcode']) ? $posted['billing_postcode'] : '';
    
    // Call the Delivery Checker API to verify if the postcode is in the delivery area
    $response = wp_remote_get("https://cdn.deliverychecker.co/api/v1/check-postcode?postcode=" . urlencode($postcode) . "&widget-id=166f5152dc8d7b");

    if (is_wp_error($response)) {
        wc_add_notice(__('Could not verify your postcode. Please try again later.'), 'error');
        return;
    }

    $body = wp_remote_retrieve_body($response);
    $data = json_decode($body, true);

    // Check the response for a valid delivery area
    if (isset($data['status']) && $data['status'] === 'error') {
        wc_add_notice(__('Sorry, we do not deliver to your postcode.'), 'error');
    }
}
