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!


当前回答

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

这就是它是如何为我工作的,family_id是自动增量的主键,我使用Laravel7

    public function store(Request $request){
        $family = new Family();
        $family->family_name = $request->get('FamilyName');
        $family->family_no = $request->get('FamilyNo');
        $family->save();
        //family_id is the primary key and auto increment
        return redirect('/family/detail/' .  $family->family_id);
    }

同样在Model Family文件中,应该将增量设置为true,否则上面的$ Family——>family_id将返回空

    public $incrementing = true;
  

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);

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.');
    }

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
]);

参考:https://laravel.com/docs/5.1/queries插入

这在laravel 4.2中是可行的

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