Thank you for help!

use App\Models\User;
use Maatwebsite\Excel\Concerns\ToModel;
use Illuminate\Support\Facades\Hash;
class AlumniImport implements ToModel
{
/**

*
* #return \Illuminate\Database\Eloquent\Model|null
*/
public function model(array $row)
{
return new User([
'code' => $row["code"],
'first_name' => $row["first_name"],
'last_name' => $row["last_name"],
'username' => $row["username"],

Answer 1

You can confirm my suggestion by doing a var_dump($row);die();
what i found on the package Maatwebsite, the $row has numeric indexes.
try this
class AlumniImport implements ToModel
{
/**
* #param array $row
*
* #return \Illuminate\Database\Eloquent\Model|null
*/
public function model(array $row)
{
return new User([
'code' => $row[0],
'first_name' => $row[1],
'last_name' => $row[2],
'username' => $row[3],
'password' => Hash::make($row[4]),
'tel' => $row[5],
'email' => $row[6],
'gender' => $row[7],
'birthday' => $row[8],
'address' => $row[9],
'status_id' => $row[10],
]);
}
}
-----edit-----
dont forget to put the fields in the $fillable of the User::class
class User extend Model
{
protected $fillable = ['code','first_name', 'last_name', 'username', 'password', 'tel', 'email', 'gender', 'birthday', 'address', 'status_id'];
.....
}
if you dont wanna put these fields as fillable and i dont recommend you to do it (especially for the password field) you can do it this way;
class AlumniImport implements ToModel
{
/**
* #param array $row
*
* #return \Illuminate\Database\Eloquent\Model|null
*/
public function model(array $row)
{
$user = new User();
$user->code = $row[0];
$user->first_name = $row[1];
$user->last_name = $row[2];
$user->username = $row[3];
$user->password = Hash::make($row[4]);
$user->tel = $row[5];
$user->email = $row[6];
$user->gender = $row[7];
$user->birthday = $row[8];
$user->address = $row[9];
$user->status_id = $row[10];
return $user;
}
}

Add this line in your AlumniImport class:
use Maatwebsite\Excel\Concerns\WithHeadingRow;
After this, include WithHeadingRow in your AlumniImport class like this:
class AlumniImport implements ToModel,WithHeadingRow
