To make the phone number field not required in WooCommerce using the functions.php file, you can use the woocommerce_billing_fields filter hook. This hook allows you to modify the billing fields that are displayed on the checkout page in WooCommerce.
Here is an example of how you can use this hook to make the phone number field not required:
// Make the phone number field not required in WooCommerce
// More snippets at wpunplugged.com
function make_phone_not_required( $fields ) {
$fields['billing_phone']['required'] = false;
return $fields;
}
add_filter( 'woocommerce_billing_fields', 'make_phone_not_required' );In this example, we are using the required key to set the billing_phone field to not required. You can use this same approach to make any other billing field not required as well.
It’s important to note that this code will only affect the phone number field on the checkout page. If you want to make the phone number field not required in other areas of your site, you will need to use a plugin or additional code to do so.
