I'm trying to Sum the value from database to other value. But It keeps only insert the value not the sum of the value. Any ideas?
foreach ($isisjkirims as $key => $isisjkirim)
{
IsiSJKirim::where('IsiSJKir', $isisjkir[$key])
->update(['QSisaKemInsert' => 'QSisaKemInsert' + $qtertanda[$key]]);
} ^
i think this one
