你可以使用$this构造函数变量在当前函数或控制器中实现“使用Laravel Eloquent最后插入Id”(不添加任何额外列)。

public function store(Request $request){
    $request->validate([
        'title' => 'required|max:255',
        'desc' => 'required|max:5000'
    ]);

    $this->project = Project::create([
        'name' => $request->title,
        'description' => $request->desc,
    ]);

    dd($this->project->id);  //This is your current/latest project id
    $request->session()->flash('project_added','Project added successfully.');
    return redirect()->back();

}

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);
}

对于Laravel，如果你插入一个新记录并调用$data->save()，这个函数执行一个insert查询并返回主键值(默认为id)。

你可以使用以下代码:

if($data->save()) {
    return Response::json(array('status' => 1, 'primary_id'=>$data->id), 200);
}

这在laravel 4.2中是可行的

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

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 ;

这里有一个例子:

public static function saveTutorial(){

    $data = Input::all();

    $Tut = new Tutorial;
    $Tut->title = $data['title'];
    $Tut->tutorial = $data['tutorial'];   
    $Tut->save();
    $LastInsertId = $Tut->id;

    return Response::json(array('success' => true,'last_id'=>$LastInsertId), 200);
}
