我用过这个，但它返回null值

After $order->save(), $order->so_idshould be the last id inserted. Your code should be as below.
之后$order->save()，$order->so_id应该是最后插入的 id。您的代码应如下所示。
$order = new Store_order;
$order->invoice_id = $signed['invoice_id'];
$order->save();
$invoice = $order->so_id;

You can get it by like below :
您可以通过如下方式获得它：
$order = new Store_order;
$order->invoice_id = $signed['invoice_id'];
$invoice = $order->save();
echo $invoice->so_id;
in this case you no need to store in one variable and then access it, You can get the inserted records by calling the model object itself :
在这种情况下，您无需存储在一个变量中然后访问它，您可以通过调用模型对象本身来获取插入的记录：
$order = new Store_order;
$order->invoice_id = $signed['invoice_id'];
$order->save();
// echo $order; => will return entire stored last record.
echo $order->so_id;
Make sure so_id is autoincrement.
确保 so_id 是自动递增的。

Try this once it worked for me where $mode->save(); was only returning true.
试试这个，一旦它对我有用， $mode->save(); 只是返回true。
$mylastid = DB::getPdo()->lastInsertId();

In case of you did overwride the name of primary key in the model as in next case:
如果您确实在模型中覆盖了主键的名称，如下一种情况：
protected $primaryKey = 'your_table_id_name';
use:
用：
$id = $your_variable_save->your_table_id_name
if not:
如果不：
$id = $your_variable_save->id

$ObjTable->nane = $name;
$ObjTable->save();
echo $ObjTable->id;
this will be display last inserted id.
这将显示最后插入的 ID。
