Simple wordpress php code

Hello, I have a website(link to be shared in DM)

I need to add a simple validation code on woocommere checkout page.

I have a field which is using an appointment calendar. This field needs be compulsory before Place Order button can be pressed. I am using a plugin called WooCommerce Checkout Field Editor(paid plugin), the appointment plugin is Wappointment(Paid).

need to add a validation rule if the customer books an appointment only then can be place an order for other item.

I have a piece a code.

add_action('woocommerce_checkout_process', 'misha_check_if_selected');

function misha_check_if_selected() {

// you can add any custom validations here

if ( empty( $_POST['paragraph-7259099911'] ) )

wc_add_notice( 'Please book your appointment', 'error' );
