You should look at the first code example that I gave then with the switch case based on the url field. A switch/case statement is the same as and if/elseif statement. The main difference is that it’s a lot cleaner.
Think of it like this
$bookingfield = get_field('accom_booking_link');
if ($bookingfield == 'first url') {
} elseif ($bookingfield == 'second url') {
} elseif ($bookingfield == 'third case') {
} elseif ($bookingfield == 'fourth case') {
} else {
// default case
}
This gets quite cumbersome after several elseif’s and is horrible to look at an manage, but can be done this way if you want. When dealing with many possibilities a switch statement can drastically reduce the amount of typing you need to do to code it.
