我目前正在使用下面的代码在一个表中插入数据:

<?php

public function saveDetailsCompany()
{
    $post = Input::All();

    $data = new Company;
    $data->nombre = $post['name'];
    $data->direccion = $post['address'];
    $data->telefono = $post['phone'];
    $data->email = $post['email'];
    $data->giro = $post['type'];
    $data->fecha_registro = date("Y-m-d H:i:s");
    $data->fecha_modificacion = date("Y-m-d H:i:s");

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

我想返回插入的最后一个ID,但我不知道如何获取它。

亲切的问候!

最短的方法可能是在模型上调用refresh():

public function create(array $data): MyModel
{
    $myModel = new MyModel($dataArray);
    $myModel->saveOrFail();
    return $myModel->refresh();
}

在laravel 5中:你可以这样做:

use App\Http\Requests\UserStoreRequest;
class UserController extends Controller {
    private $user;
    public function  __construct( User $user )
    {
        $this->user = $user;
    }
    public function store( UserStoreRequest $request )
    {
       $user= $this->user->create([
            'name'              => $request['name'],
            'email'             => $request['email'],
            'password'          => Hash::make($request['password'])
        ]);
        $lastInsertedId= $user->id;
    }
}
$objPost = new Post;
$objPost->title = 'Title';
$objPost->description = 'Description';   
$objPost->save();
$recId = $objPost->id; // If Id in table column name if other then id then user the other column name

return Response::json(['success' => true,'id' => $recId], 200);

在save $data之后->save()。所有数据都被推入$data内。因为这是一个对象,当前行刚刚保存在$data中。所以last insertId将在$data->id中找到。

响应代码为:

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

最短的方法可能是在模型上调用refresh():

public function create(array $data): MyModel
{
    $myModel = new MyModel($dataArray);
    $myModel->saveOrFail();
    return $myModel->refresh();
}

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

$id = DB::table('users')->insertGetId([
    'email' => 'john@example.com',
    'votes' => 0
]);
