如何在laravel中获取数组内的对象值？

Question

我从控制器的视图（$ rquest）中收到了此数据表格{} 如何在带有x个项{}的产品数组中获取“ product_id”值以在控制器中使用它们？

form: {
   id: null,
   sale_number: 2,
   client: null,
   products: [
      { product_id:1,description: null, quantity:1, price: 1}
      { product_id:2,description: null, quantity:1, price: 1}
      { product_id:3,description: null, quantity:1, price: 1}
      .....etc
   ],
}

Answer 1

您可以使用$request->products和foreach

foreach($request->products as $product)
{
    $product['product_id']
}

如果要将它们保存在数组中，请执行此操作

$product_id_array = array();
foreach($request->products as $product)
{
    product_id_array[] = $product['product_id'];
}
