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!

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;
  

其他回答

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

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);
}

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);

将记录保存到数据库后,可以通过$data->id访问id

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

你可以这样做:

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

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