For anyone who also likes how Jeffrey Way uses Model::create() in his Laracasts 5 tutorials, where he just sends the Request straight into the database without explicitly setting each field in the controller, and using the model's $fillable for mass assignment (very important, for anyone new and using this way): I read a lot of people using insertGetId() but unfortunately this does not respect the $fillable whitelist so you'll get errors with it trying to insert _token and anything that isn't a field in the database, end up setting things you want to filter, etc. That bummed me out, because I want to use mass assignment and overall write less code when possible. Fortunately Eloquent's create method just wraps the save method (what @xdazz cited above), so you can still pull the last created ID...

public function store() {

    $input = Request::all();
    $id = Company::create($input)->id;

    return redirect('company/'.$id);
}

保存后，$data->id应该是最后插入的id。

$data->save();
$data->id;

可以这样使用。

return Response::json(array('success' => true, 'last_insert_id' => $data->id), 200);

更新laravel版本试试这个

return response()->json(array('success' => true, 'last_insert_id' => $data->id), 200);

为劳拉***

首先创建一个对象，然后为该对象设置属性值，然后保存对象记录，然后获取最后插入的id。如

$user = new User();        

$user->name = 'John';  

$user->save();

//现在获取最后插入的id

$insertedId = $user->id;

echo $insertedId ;

可选方法为:

$lastID = DB::table('EXAMPLE-TABLE')
                ->orderBy('id', 'desc')
                ->first();

$lastId = $lastProduct->id;

来自Laravel 5.8版本

有几种方法可以获取最后插入的id。所有这些都是基于您在插入时使用的方法。在这种情况下，你可以得到最后一个。

$data->save();
$data->id;

对于其他人谁需要知道如何获得最后插入id，如果他们使用其他插入方法，这里是如何:

使用create()方法 书=书:美元:创建(['名字' = > ' Laravel战士']); $lastId = $book->id; 使用insertGetId () $id = DB::table('books')->insertGetId(['name' => 'Laravel warrior']);$lastId = $id; 使用lastInsertId()方法 $lastId = DB::getPdo()->lastInsertId();

参考https://easycodesolution.com/2020/08/22/last-inserted-id-in-laravel/

这在laravel 4.2中是可行的

$id = User::insertGetId([
    'username' => Input::get('username'),
    'password' => Hash::make('password'),
    'active'   => 0
]);
