How to pass parameters from client to server callback, store data in array and send it back to client

Question

I want to send the vehicle variable from the client to the server callback, there I will verify if the person with the steam id owns the vehicle he is trying to open, if he does then all the license plates he owns will be saved in into an array and sent back to the client.

How to pass parameters from client to server callback?

#Client

function openmenuvehicle()
    local playerPed = PlayerPedId()
    local coords = GetEntityCoords(playerPed)
    local vehicle = nil

    if IsPedInAnyVehicle(playerPed, false) then
        vehicle = GetVehiclePedIsIn(playerPed, false)
    else
        vehicle = getVehicleInDirection(3.0)

        if not DoesEntityExist(vehicle) then
            vehicle = GetClosestVehicle(coords, 3.0, 0, 70)
        end
    end


    if DoesEntityExist(vehicle) then
        local lockStatus = GetVehicleDoorLockStatus(vehicle)
        if lockStatus == 0 or lockStatus == 1 then
            local trunkpos = GetWorldPositionOfEntityBone(vehicle, GetEntityBoneIndexByName(vehicle, "boot"))
            local distanceToTrunk = GetDistanceBetweenCoords(coords, trunkpos, 1)

            if distanceToTrunk <= 1.25 or (trunkpos.x + trunkpos.y + trunkpos.z) == 0.0 then

                ESX.TriggerServerCallback('esx_inventoryhud_trunk:getOwner', function(isOwner)
                print(isOwner)

                    if isOwner then 
                        TriggerEvent(
                        "mythic_progbar:client:progress",

                            useWhileDead = false,
                            canCancel = true,
                            controlDisables = {
                                disableMovement = true,
                                disableCarMovement = true,
                                disableMouse = false,
                                disableCombat = true
                            }
                        },
                        function(status)
                            if not status then
                                currentVehicle = vehicle

                                OpenCoffreInventoryMenu(GetVehicleNumberPlateText(vehicle), Config.VehicleLimit[class])
                            end
                        end
                        )
                    end
                end)
            else

#Service-Terminal

ESX.RegisterServerCallback("esx_inventoryhud_trunk:getOwner", function(source, cb, plate)

    local id = GetPlayerIdentifiers(source)[1]
    
    MySQL.Async.fetchAll("SELECT plate FROM owned_vehicles WHERE owner = @owner", {['@owner'] = id}, function(data)
        if data[1].owner == id then 
            return cb(true)
        else

All you need to do is add an additional parameter to the client's callback. If you define the board above like I did below, then ",board" will be fine.

local plate = GetVehicleNumberPlateText(vehicle)
ESX.TriggerServerCallback('esx_inventoryhud_trunk:getOwner', function(isOwner, owned_vehicles)
    print(isOwner)

    if isOwner then
        TriggerEvent(
            "mythic_progbar:client:progress",
            {
                name = "Open_Trunk",
                duration = Config.OpenTime,
                label = 'ABRINDO MALA',
                useWhileDead = false,
                canCancel = true,
                controlDisables = {
                disableMovement = true,
                disableCarMovement = true,
                disableMouse = false,
                disableCombat = true
            }
        },
        function(status)
            if not status then
                currentVehicle = vehicle

                SetVehicleDoorOpen(vehicle, 5, false, false)
                local class = GetVehicleClass(vehicle)
                OpenCoffreInventoryMenu(plate, Config.VehicleLimit[class])
            end
        end)
    end
end, plate)

For the server side, you just need cb(data).

ESX.RegisterServerCallback("esx_inventoryhud_trunk:getOwner", function(source, cb, plate)

    local id = GetPlayerIdentifiers(source)[1]

    MySQL.Async.fetchAll("SELECT plate FROM owned_vehicles WHERE owner = @owner", {['@owner'] = id}, function(data)
        local found = false;
        for i = 1, #data do
            local this = data[i]
            if this.plate == plate then
                cb(true, data)
                found = true; -- need to do this to prevent to callbacks
            end
        end
        if not found then cb(false, {}) end
    end)
end)
