如何将 foreach 循环数据存储到另一个模型中？

我想将我的 foreach 循环数据存储到另一个变量中。问题是我可以将数据存储到数据库中，但是当我 dd() 输出时，它只显示分配给模型的最后一个数据。

如何从新模型中获取数组数据？

foreach ($carts as $cart)
{
    $buy = new Buy();               
    $buy->product_id = $cart->product_id;
    $buy->user_id = $cart->user_id;
    $buy->price = $cart->price;
    $buy->extened = $cart->extened;
    $buy->installation = $cart->installation;
    $buy->support = $cart->support;             
    $buy->feature_image = $cart->feature_image;
    $buy->name = $cart->name;
    $buy->save();               
}

dd($buy);  // it returns only last inserted data ..

当然，您将获得最新插入的数据。使用以下代码获取所有插入的数据。这是因为在最后执行foreach循环时，$buy将获得最新$cart信息。

您可以使用以下代码获取所有Buy模型。我们将创建一个空数组并添加$buy到该数组中。

$buys = array(); // I don't care about the name of the array lol.
foreach ($carts as $cart)
{
    $buy = new Buy();               
    $buy->product_id = $cart->product_id;
    $buy->user_id = $cart->user_id;
    $buy->price = $cart->price;
    $buy->extened = $cart->extened;
    $buy->installation = $cart->installation;
    $buy->support = $cart->support;             
    $buy->feature_image = $cart->feature_image;
    $buy->name = $cart->name;
    $buy->save();

    array_push($buys,$buy);        
}

它会将每条记录存储在$buys数组中，然后您可以对该数组执行任何您想做的操作。

让我知道这是否是您想要的。如果您还有其他问题，请告诉我。

更新：您可以运行foreach循环$buys来显示/更新/删除条目。
