【中文标题】更新不起作用时 Laravel 保存（奇怪的行为）

【英文标题】：Laravel save when update not working (strange behavior)

【问题描述】：

我正在使用 Laravel 8，我尝试更新数据，但它不会保存，这真的很奇怪。

控制器

private function _generatePaymentToken($kode)

    $this->initPaymentGateway();
    $pnd = new Pendaftar;
    $pnd = $pnd::where('nohp', $kode)->get();
    if ($pnd->count()) 
        $customerDetails = [
            'first_name' => $pnd[0]->nama,
            'last_name' => $pnd[0]->nama,
            'email' => $pnd[0]->email,
            'phone' => $pnd[0]->nohp,
        ];

        $params = [
            'transaction_details' => [
                'order_id' => $pnd[0]->kode_transaksi,
                'gross_amount' => 5000,
            ],
            'customer_details' => $customerDetails,
            'expiry' => [
                'start_time' => date('Y-m-d H:i:s T'),
                'unit' => setting('site.unit_expire'),
                'duration' => setting('site.time_expired'),
            ],
        ];

        $snap = \Midtrans\Snap::createTransaction($params);

        $pendaftar = Pendaftar::find($pnd[0]->id);

        $pendaftar->token = $snap->token;
        $pendaftar->save;

        // dd($pendaftar->save);
        return $snap;

     else 
        return view('404');
    

型号

namespace App;

use Illuminate\Database\Eloquent\Model;


class Pendaftar extends Model

    protected $table = 'pendaftar';
    protected $primary_key = 'id';
    protected $fillable = ['nama, email, nohp,orangtuawali, alamat, tempat_tanggal_lahir,asal_sekolah, satutahun_regular, satutahun_hybrid,duatahun, sarjana_plus, ihcp, ecp, periode_pendaftaran, created_at, updated_at, deleted_at, kode_refrensi, kode_transaksi,kampus,token'];

返回前的$pendaftar->save 不起作用

我尝试dd($pendaftar->save)它给我null

如果我 dd($pendaftar) 它会给我这个

App\Pendaftar #1840
  #table: "pendaftar"
  #primary_key: "id"

我真的不知道这有什么问题，或者我想念什么？

【问题讨论】：

这个$pendaftar->save;保存应该是一个函数$pendaftar->save();

天哪，我想我现在应该去睡觉了。谢谢

【参考方案1】：

您的 $fillable 数组定义不正确 - 每个列名都应该是数组的一个元素 - 用引号括起来。否则不允许任何字段进行批量分配。

这意味着即使更新或保存方法不会引发错误 - 这些列的数据也不会保存到数据库中。

namespace App;

use Illuminate\Database\Eloquent\Model;


class Pendaftar extends Model

    protected $table = 'pendaftar';
    protected $primary_key = 'id';
    protected $fillable = [
        'nama',
        'email',
        'nohp',
        'orangtuawali',
        'alamat',
        'tempat_tanggal_lahir',
        'asal_sekolah',
        'satutahun_regular',
        'satutahun_hybrid',
        'duatahun', 
        'sarjana_plus',
        'ihcp',
        'ecp',
        'periode_pendaftaran',
        'created_at',
        'updated_at',
        'deleted_at',
        'kode_refrensi',
        'kode_transaksi',
        'kampus,token'
    ];

正如@bhucho 所指出的，save() 是一种方法而不是属性，所以声明应该是

$pendaftar->save();
