Question

所以基本上我正在这样做：

Laptop::create([
    'user_id' => 1,
    'name' => $request->name,
    'brand' => $request->brand,
    'SN' => $request->SN,
    'price' => $request->price
]);

如何保存新创建的资源的ID？由于ID字段是自动递增的，因此不需要手动插入。例如，如果ID为47，则我需要能够将ID存储在本地以供使用。就像将其存储在名为$ID

的变量中一样

因此，我可以创建包含笔记本电脑上的信息（例如笔记本电脑部件）的元行。他们都需要有一个{_1}}

的parent_id

Answer 1

创建将返回Laptop模型的对象。

$laptop = Laptop::create([
 'user_id' => 1,
 'name' => $request->name,
 'brand' => $request->brand,
 'SN' => $request->SN,
 'price' => $request->price
]);

$id = $laptop->id;

OR

  $laptop = Laptop::create([
 'user_id' => 1,
 'name' => $request->name,
 'brand' => $request->brand,
 'SN' => $request->SN,
 'price' => $request->price
])->id;

Answer 2

$laptop = Laptop::create([
    'user_id' => 1,
    'name' => $request->name,
    'brand' => $request->brand,
    'SN' => $request->SN,
    'price' => $request->price
]);

$id = $laptop->id;

Answer 3

要获取最近添加的ID，您可以遵循以下代码

$laptop = Laptop::create([
    'user_id' => 1,
    'name' => $request->name,
    'brand' => $request->brand,
    'SN' => $request->SN,
    'price' => $request->price
]);

$id = $laptop->id;  //You get recently added id
echo $id;

Answer 4

create方法返回保存的模型实例。所以用它链接：

$laptop = Laptop::create([
    'user_id' => 1,
    'name' => $request->name,
    'brand' => $request->brand,
    'SN' => $request->SN,
    'price' => $request->price
]);

$id = $laptop->id;

$id是新添加的数据的必需ID。

Answer 5

$id = Laptop::lastInsertId();

或

$id = Laptop::create([
    'user_id' => 1,
    'name' => $request->name,
    'brand' => $request->brand,
    'SN' => $request->SN,
    'price' => $request->price
])->id;
