Can’t get wordpress to send additional merge tags from woocommerce to mailchimp

I just did this myself. The issue if you need to use the ‘Address’ merge tag. Then within that the address tags need to be in an array. Below is my code the syncs over billing address and phone.

NOTE: For phone number to display right in MailChimp I found you need to format the telephone before sending it over.

function custom_format_telephone($phone_number)
{
//Remove all formatting
$cleaned = preg_replace(‘/[^[:digit:]]/’, ”, $phone_number);
//seperate phone into its parts
preg_match(‘/(\d{3})(\d{3})(\d{4})/’, $cleaned, $matches);
//Send back phone number in xxx-xxx-xxxx format.
return “{$matches[1]}-{$matches[2]}-{$matches[3]}”;
}

function custom_user_merge_tags($merge_vars, $user) {

// Get the WooCommerce customer object
$customer = new WC_Customer($user->ID);
// Build Address Array
$address = array();
$address[“addr1”] = $customer->get_billing_address_1();
$address[“addr2”] = $customer->get_billing_address_2();
$address[“city”] = $customer->get_billing_city();
$address[“state”] = $customer->get_billing_state();
$address[“zip”] = $customer->get_billing_postcode();
$address[“country”] = $customer->get_billing_country();

//Assign to MailChimp merge tag name
$merge_vars[‘ADDRESS’] = $address;
$merge_vars[‘PHONE’] = custom_format_telephone((string) $customer->get_billing_phone());

// return the merge tag array to be submitted.
return $merge_vars;
}

add_filter(‘mailchimp_sync_user_mergetags’, ‘custom_user_merge_tags’, 100, 2);`
