in my laravel livewire component, i have this code.
private $wireAlertService;
public function mount() {
$this->supervisors = User::getSupervisors();
$this->wireAlertService = new LivewireAlertService();
// dd($this->wireAlertService);
}
the commented outdd()
dumps the instance ofLivewireAlertService
as wanted.
however, in other method, that fire's on button'swire:click
, the variable$wireAlertService
is null.
public function approveMany($attrs) {
// code
dd($this->wireAlertService, (new LivewireAlertService()));
// $this->wireAlertService->success($this);
// (new LivewireAlertService())->success($this);
}
in methodapproveMany()
dd()
dumps this
null
App\Services\LivewireAlertService {#2760}
therefore$this->wireAlertService->success($this);
does not work (the desired one)
while(new LivewireAlertService())->success($this);
works, but i don't like it as much.
As described within the introduction of Livewire,protected
andprivate
properties do not persist. Therefore, after your mount is completed, the property is reset.
If you wish to have it be persistent, you need to define it immediately, but this is not possible using a class instantiation, or make the propertypublic
.
Dependent on what the service is, you could inject it into each method, much like you would with the .
