php - 如何在 Eloquent ORM laravel 中获取最后插入的 ID

Question

我正在使用“Laravel 中的 Eloquent ORM”执行数据库操作。我只想取数据库中的最后一个插入 id(不是最大 id)。

我在 laravel Eloquent ORM 中搜索了最后一个插入 ID，我得到了以下链接(Laravel, get last insert id using Eloquent)，它指的是从以下函数“$data->save() 中获取最后一个插入 id ".

但是我需要得到

“模型::创建($数据)”；

我的查询:

GeneralSettingModel::create($GeneralData);

User::create($loginuserdata);

如何检索最后插入的 ID？

Answer 1

如文档所说:Insert, update, delete

"You may also use the create method to save a new model in a single line. The inserted model instance will be returned to you from the method. However, before doing so, you will need to specify either a fillable or guarded attribute on the model, as all Eloquent models protect against mass-assignment.

After saving or creating a new model that uses auto-incrementing IDs, you may retrieve the ID by accessing the object's id attribute:"

$insertedId = $user->id;

因此在您的示例中:

$user = User::create($loginuserdata);
$insertedId = $user->id;

然后在 table2 上

$input['table2_id'] = $insertedId;
table2::create($input);
