'pembelian_kode' => 'required',
'barang_kode' => 'required',
'pembelian_total' => 'required',
'pembelian_qty' => 'required',
'supplier_id' => 'required',
]);
$cid = Input::POST('cid');
$cg = PembelianModel::create($request->all());
if($cg){
for($count = 0; $count < sizeof($cid); $count++){
DB::table('pembelian_details')->insert([
'pembelian_kode' => $request['pembelian_kode'], 'barang_kode' => $request['barang_kode'], 'pd_qty' => $request['pembelian_qty']]
);
}
}
return redirect()->route('pembelians.index')
->with('success','Data berhasil ditambah');

I just modified your script .Hope this will work
Problems:
$request['barang_kode']
Missing index
$request is an object not array
$cid = $request->cid;
$cg = PembelianModel::create($request->all());
if($cg){
for($count = 0; $count < count($cid); $count++){
DB::table('pembelian_details')->insert([
'pembelian_kode' => $request->pembelian_kode[$count],
'barang_kode' => $request->barang_kode[$count],
'pd_qty' => $request->pembelian_qty[$count]
]
);
}
}
return redirect()->route('pembelians.index')
->with('success','Data berhasil ditambah');
