Woocommerce Checkout Shourtcode not working

Hi,
I noticed when I added some codes to function.php file to remove a few fields on the checkout page the credit card fields get disabled on custom checkout pages.

A few developers gave up on this… Any suggestions?

Thanks!

code added:

/* WooCommerce: The Code Below Removes Checkout Fields */
add_filter( ‘woocommerce_checkout_fields’ , ‘custom_override_checkout_fields’ );

function custom_override_checkout_fields( $fields ) {

unset($fields[‘billing’][‘billing_last_name’]);

unset($fields[‘billing’][‘billing_company’]);

unset($fields[‘billing’][‘billing_address_1’]);

unset($fields[‘billing’][‘billing_address_2’]);

unset($fields[‘billing’][‘billing_city’]);

unset($fields[‘billing’][‘billing_postcode’]);

unset($fields[‘billing’][‘billing_country’]);

unset($fields[‘billing’][‘billing_state’]);

unset($fields[‘billing’][‘billing_phone’]);

unset($fields[‘order’][‘order_comments’]);

unset($fields[‘account’][‘account_username’]);

unset($fields[‘account’][‘account_password’]);

unset($fields[‘account’][‘account_password-2’]);

return $fields;

}
