livewire code
public $plu='';
public $buttun_disable='';
protected $listeners = ['renderrecipt' => '$refresh'];
public function cari_plu_master()
{
$today = \Carbon\carbon::today();
$now = \Carbon\carbon::now();
$cek_data_plu = master_item::where('plu',$this->plu)->exists();
$cek_data_recipt = proses_recipt::wheredate('tgl_recipt',$today)->where('plu',$this->plu)->exists();
// dd($cek_data_plu,$cek_data_recipt);
if ($cek_data_plu == true) {
//cek pernah input plu pada tanggal sama untuk recipt
if ($cek_data_recipt == false) {
$data_plu = master_item::where('plu',$this->plu)->first();
//create data
proses_recipt::create([
'plu'=> $data_plu->plu,
'deskripsi'=> $data_plu->deskripsi,
'stok_lama'=>$data_plu->stok,
'tgl_recipt'=>$now,
'user_proses'=>Auth::user()->name,

$this->emit('renderrecipt');
} else {

->where('plu',$this->plu)->first();
proses_recipt::wheredate('tgl_recipt',$today)
->where('plu',$this->plu)->update([
'stok_masuk'=> $data_recipt->stok_masuk+1,
