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!

使用雄辩的模型

$user = new Report();        
$user->email= 'johndoe@example.com';  
$user->save();
$lastId = $user->id;

使用查询生成器

$lastId = DB::table('reports')->insertGetId(['email' => 'johndoe@example.com']);

下面是我们如何在Laravel 4中获得最后一个插入id

public function store()
{
    $input = Input::all();

    $validation = Validator::make($input, user::$rules);

    if ($validation->passes())
    {

     $user= $this->user->create(array(
            'name'              => Input::get('name'),
            'email'             => Input::get('email'),
            'password'          => Hash::make(Input::get('password')),
        ));
        $lastInsertedId= $user->id; //get last inserted record's user id value
        $userId= array('user_id'=>$lastInsertedId); //put this value equal to datatable column name where it will be saved
        $user->update($userId); //update newly created record by storing the value of last inserted id
            return Redirect::route('users.index');
        }
    return Redirect::route('users.create')->withInput()->withErrors($validation)->with('message', 'There were validation errors.');
    }

你可以这样做:

$result=app('db')->insert("INSERT INTO table...");

$lastInsertId=app('db')->getPdo()->lastInsertId();

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();

}

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();
}

您可以很容易地获取最后插入的记录Id

$user = User::create($userData);
$lastId = $user->value('id');

从DB中最后插入的记录中获取Id是一个很棒的技巧。
