Licenses

Check whether a player holds a specific driving or skill license.

HasLicense (Client)

The license check is initiated from the client using a server callback:

KOJA.Client.HasLicense(licenseName, callback)

Parameter	Type	Description
licenseName	string	Name of the license to check
callback	function(result: boolean)	Called with the result

Example

KOJA.Client.HasLicense('driver', function(has)
    if not has then
        print('No driver license')
    end
end)

License Names

Framework	License Examples
ESX	"driver", "weapon", "pilot", "boat"
QBCore	"driver", "weapon", "hunting", "business"

The name you pass must match what is stored in the framework's database.

How it Works

Internally, KOJA.Client.HasLicense triggers the server callback koja-lib:HasLicense. The server then queries the framework:

• ESX — triggers the esx_license:checkLicense event

• QBCore — reads Player.PlayerData.metadata.licenses

• Custom — returns false by default (implement in CustomFramework.Server)

Implementing License Check for Custom Framework

In editable/custom/framework_server.lua, the license check is handled by the koja-lib:HasLicense callback. If you use a custom framework you can override this by registering the callback yourself before koja-lib loads, or by modifying server/modules/licenses.lua.

Example for a custom framework:

-- In your own server script
KOJA.Server.RegisterServerCallback('koja-lib:HasLicense', function(source, licenseName, cb)
    local player = MyFramework.GetPlayer(source)
    if not player then return cb(false) end
    cb(player.hasLicense(licenseName))
end)
