Question

I want to update the combobox, but when i run the program the error appears. the error said

Undefined variable: jenis (View: D:\laravel\makanan\resources\views\edit_upload.blade.php)

this is sintax in the controller:

public function prosesedit($id, Request $request)
    {
        $makan = Gambar::find($id);
        $nama_file = $makan->file;
        $jenis = JenisMkn::select('id_jenis','jenis_makanan')->get();


        if($request->hasfile('file'))
        {
            $file = $request->file('file');
            $nama_file = time()."_".$file->getClientOriginalName();
            $tujuan_upload = 'image_file';
            $file->move($tujuan_upload,$nama_file);
        }

        $makan->update([
            'file'=>$nama_file,
            'nama_makanan'=>$request->makan,
            'kode_makanan'=>$request->jenis,
        ]);
        return redirect(route('makan'));
    }

In Your edit function where you return the edit_upload.blade.php,with this return please pass the variable jenis like

return view('edit_upload',compact('jenis'));
