Hi there,
I’m not quite understanding the context of how the callbacks are supposed to work, could someone maybe explain to me when to use callbacks, and how to use em. Would highly appreciate it!

Callbacks are a handy way of getting data from the server without using multiple events.
Client
function isPlateTaken(plate)
TriggerServerEvent('event1', plate)
end
RegisterNetEvent('event2', function(taken)
if taken then
ESX.ShowNotification('Plate is taken')
end
end
Server
RegisterNetEvent('event1', function(plate)
local taken = MySQL.scalar.await('SELECT plate FROM owned_vehicles WHERE plate = ?', {plate})
TriggerClientEvent('event2', source, taken) -- return the data to the client
end
Client
function isPlateTaken(plate)
ESX.TriggerServerCallback('event1', function(taken)
if taken then
ESX.ShowNotification('Plate is taken')
end
end, plate)
end
Server
ESX.RegisterServerCallback('event1', function(source, cb, plate)
local taken = MySQL.scalar.await('SELECT plate FROM owned_vehicles WHERE plate = ?', {plate})
cb(taken) -- return the data to the client
end
