Empty cart if specific product not in it - wordpress

Question

So I need a little help. I have a wooocommerce webshop where there are two main products, and then 3 products, that visitors only will be able to buy, if one of the two main products are in the cart. I have found some code, that works like this: If I remove a main product, the additional product will be removed automatic, which it should. My problem is, i dont know how to modify the code, so it includes 3 products id's (one id, for each of the additional products). I have tried plenty of things, but cant get it to work. Can you maybe help me? This it the code I have (which now contains one product id, and it should contain three id's):
// Add to cart validation for the discounted product
add_filter( 'woocommerce_add_to_cart_validation', 'check_specific_discounted_product', 10, 3 );
function check_specific_discounted_product( $passed, $product_id, $quantity ) {
// Settings
$discounted_product_id = 3008;
if( WC()->cart->is_empty() && $discounted_product_id == $product_id ) {
wc_add_notice( __("This product can't be purchased alone."), 'notice' );
return false;
}
return $passed;
}
// Removing the discounted product if it's alone in cart
add_action( 'woocommerce_before_calculate_totals', 'conditionally_remove_a_discounted_product' );
function conditionally_remove_a_discounted_product( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Settings
$discounted_product_id = 3008;
// Initializing variables
$discounted_item_key = false;
// Loop through cart items (first loop)
foreach ( $cart->get_cart() as $cart_item_key => $cart_item ){
// When free productis is cart
if ( in_array( $discounted_product_id, array($cart_item['product_id'], $cart_item['variation_id']) ) ) {
$discounted_item_key = $cart_item_key;
}
// if any other product is in cart: EXIT
else {
return;
}
}
// When the discounted product is alone in cart, remove it
if( $discounted_item_key ) {
// display notice on removal (optional)
wc_clear_notices();
wc_add_notice( __("The discounted product can't be purchased alone and has been removed."), 'notice' );
$cart->remove_cart_item( $discounted_item_key ); // Remove
}
}
I have tried to modify the code like this:
$discounted_product_id = 3004, 3008, 3157;
And like this:
$discounted_product_id = 3004;$discounted_product_id = 3008;$discounted_product_id = 3157;
Also like this:
$discounted_product_id = array('3004','3008','3157');
But it's not working :(
