Question

why when import excel, my data I added is not saved to the database ?
i import excel with type xlsx
My controller
public function importDataPegawai(Request $request)
{
Excel::import(new ImportPegawai, $request->file('upload-pegawai'));
return redirect('dashboard-admin')->with('success','Berhasil Upload Data Pegawai');
}
My Import
<?php
namespace App\Imports;
use App\Models\PegawaiModel;
use Maatwebsite\Excel\Concerns\ToModel;
use Maatwebsite\Excel\Concerns\WithStartRow;
use Auth;
use DB;
class ImportPegawai implements ToModel, WithStartRow
{
/**
* #param array $row
*
* #return \Illuminate\Database\Eloquent\Model|null
*/
public function model(array $row)
{
foreach ($row as $data){
$data = DB::table('tbl_pegawai')->where('nip', $row[0])->get();
if (empty($data)) {
return new PegawaiModel([
'nip' => $row[0],
'nama_lengkap' => $row[1],
'pangkat' => $row[2],
'gol' => $row[3],
'jabatan' => $row[4],
'unit_kerja' => $row[5]
]);
}
}
}
public function startRow(): int
{
return 3;
}
}
When i dd($data) the result is like this
result dd
i got the data from my excel upload.
What's the problem ? why my data cannot save in the database

Answer 1

This code will return an Collection, which is an object, objects are always not empty.
DB::table('tbl_pegawai')->where('nip', $row[0])->get();
If you switch to first() it will return a model or null, effectively doing what you intended to.
DB::table('tbl_pegawai')->where('nip', $row[0])->first();

Answer 2

I have been in this situation before and figured that it can be caused by different factors. You might want to try the following:
Save the file you're about to upload to Excel 97-2003 Workbook format first.
Make sure the columns you're inserting data into is included in protected $fillable under App\PegawaiModel.
If certain cells in your spreadsheet are empty, make a validation for it.
Ex.
if ($row[0] === null) {
$row = null;
}
or if it's a string column that's not nullable, you can do
if ($row[0] === null) {
$row = 'NO DATA';
}
