Question

这是我的代码：

User::create([
    'name' => $request->name,
    'email' => $request->email,
    'cell_phone' => $request->cell_phone,
    'province_id' => $request->province,
    'city_id' => $request->city,
    'job' => $job,
    'company' => $company,
    'member_num' => $member_num,
]);

如您所知，它在数据库中插入一个新行。现在我需要获得插入行的id。我怎么能得到它？

注意到我知道，I can do the same if I use $obj->save(), and the id will be $obj->id;。但我想知道在使用create()时我该怎么做。

Answer 1

您可以使用代码

获取用户插入的ID

$userDetials = User::create([
     'name' => $request->name,
     'email' => $request->email,
     'cell_phone' => $request->cell_phone,
     'province_id' => $request->province,
     'city_id' => $request->city,
     'job' => $job,
     'company' => $company,
     'member_num' => $member_num,
]);
if(isset($userDetials->id))    
{
    //if inserted 
    return $userDetials->id;
}
else
{
   //not inserted
}

create 方法返回已保存的模型实例

Answer 2

As per the docs

create方法返回已保存的模型实例：

在你的情况下，它将是

$user = User::create(...)

Answer 3

$data = User::create([
      'name' => $request->name,
      'email' => $request->email,
      'cell_phone' => $request->cell_phone,
      'province_id' => $request->province,
      'city_id' => $request->city,
      'job' => $job,
      'company' => $company,
      'member_num' => $member_num,
]);

在create之后，$data->id应该是最后插入的ID。

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

Answer 4

此处create和save这两种方法都返回上次生成的ID，但请确保您使字段自动增加。

$userobj = User::create([
'name' => $request->name,
'email' => $request->email,
'cell_phone' => $request->cell_phone,
'province_id' => $request->province,
'city_id' => $request->city,
'job' => $job,
'company' => $company,
'member_num' => $member_num,
]);
echo $userobj->id;

如果你想使用create方法，你必须在你的模型中将所有字段定义为可填写，并且在创建和编辑中都使用save（）方法，所以习惯使用save方法是好的，

保存方法的例子

 $user = User::first();
 $user->email = 'updated@domain.com';
 $user->save();
echo $user->id;

两个方法都返回最后插入的id。我希望它有所帮助，谢谢......
