使用insertGetId同时插入和获取插入id

从医生

如果表有一个自动递增的id，则使用insertGetId方法 插入一条记录，然后检索ID:

通过模型

$id = Model::insertGetId(["name"=>"Niklesh","email"=>"myemail@gmail.com"]);

通过DB

$id = DB::table('users')->insertGetId(["name"=>"Niklesh","email"=>"myemail@gmail.com"]);

详情请访问:https://laravel.com/docs/5.5/queries#inserts

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();

}

public function store( UserStoreRequest $request ) {
    $input = $request->all();
    $user = User::create($input);
    $userId=$user->id 
}

你可以用save method获取上次插入的id;

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

所以你可以简单地写:

if ($data->save()) {
    return Response::json(array('success' => true,'inserted_id'=>$data->id), 200);
}

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);
}

这在laravel 4.2中是可行的

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