我试图复制行但没有结果,我得到的订单复制没有相应的项目。

ORDERS pk(id) auto increment
id       total       status       date
-----+-------------+-----------+-------------
118      899.58        2          2015-03-03 00:18:58
119      38.55         2          2015-03-03 00:18:58


ITEMS pk(order_id,product_id) corresponding items childs:
order_id    product_id    quantity
----------+-------------+----------
118         1115          82 
119         8965          12      /// ro replicate


$idnew = Order::find($idorder)->replicate()->save(); // create new OK
$idnewId = $idnew->id;/////obtain id of last insert  
$itemstemp = DB::table('item')->where('order_id', '=' ,$idnewId)->get();

           foreach($itemstemp as $itemte){
            DB::table('item')->insert(array(
                'order_id'   => $itemte->order_id, 
                'product_id' => $itemte->product_id,
                'quantity'   => $itemte->quantity
                )); 
            }

响应 ErrorExceptionTying to get property of non-object line $idnewId = $idnew->id;

期望的输出:

ORDERS pk(id)
id       total       status       date
-----+-------------+-----------+-------------
118      899.58        2          2015-03-03 00:18:58
119      38.55         2          2015-03-03 00:18:58
120      38.55         2          2015-03-03 00:18:58

ITEMS pk(order_id,product_id) corresponding items childs:
order_id    product_id    quantity
----------+-------------+----------
118         1115          82 
119         8965          12  
119         2255          22
120         8965          12  
120         2255          22  

请有任何想法

save()如果保存有效,则只返回一个布尔值。你应该做的是:

$new = Order::find($idorder)->replicate();
$new->save();
$itemstemp = DB::table('item')->where('order_id', '=' ,$new->id)->get();
// and so on...

另外我认为你的逻辑有点错误。这样的事情对我来说更有意义:

$new = Order::find($idorder)->replicate();
$new->save();
$items = DB::table('item')->where('order_id', $idorder)->get();
$newItems = [];
foreach($items as $item){
    $newItems[] = [
        'order_id' => $new->id,
        'product_id' => $item->product_id,
        'quantity'   => $item->quantity
    ];
}
DB::table('item')->insert($newItems);
