Visitor Pass Contact Block for React

Nowhere yet. The submit handler waits 800 milliseconds as a stand-in for a request, then shows the pass. Replace that timer in submit with a call to your visitor system: details holds the host, date, arrival window and the guest's name and email. The QR code encodes the example address in passUrl: point it at whatever your front desk scans.

It asks the browser after the page has loaded, so the server's HTML never depends on a clock. Until then every day is open; after it, weekends and days before today are unavailable on the calendar and can't be picked. A date typed into the field is checked when you submit, so a typed Saturday is turned away with a message. Reception's days live in closed at the top of the file.

It is a directory: typing filters it by name, and the host has to be one of the people listed, so a half-typed name is a problem on submit ("Choose who you are visiting from the list"). The people are fictional; replace HOSTS with your tenants. The list is a Base UI Combobox over an array of people.

It repeats the guest, host, date, arrival window and company with floor, beside a QR code that is dark on light in any theme because scanners need it. It is a status region that takes focus when it appears, so a screen reader reads it at once, and "Register another guest" brings back an empty form and puts focus on its heading. It doesn't promise anything a server would have to keep.

The label above it names the select's button for screen readers, and focus can land on it when the choice is missing. The trigger takes the id, and the label points to it with htmlFor.

Below sm the date and arrival fields stack, as do the name and email, and the button goes full width. The pass puts the QR code above the details, in two columns of facts. Dates are written in English by a fixed formatter; change dateFormat for another language.
