laravel - 使用 Eloquent Data Laravel 显示表格表单

Question

我有一个以 Eloquent 形式存储的对象结构

{"item_id": "2",
"item_color": "Black",
"item_size": "L",
"item_Quantity": "5",},

{"item_id": "2",
"item_color": "Black",
"item_size": "M",
"item_Quantity": "5",},

{"item_id": "2",
"item_color": "Black",
"item_size": "S",
"item_Quantity": "5",},

{"item_id": "2",
"item_color": "White",
"item_size": "S",
"item_Quantity": "5",},

我想要实现的是将所有具有相同item_id和item_color的item_quantity组合起来，并以这样的表格形式显示。

ItemID ItemColor ItemSize  Quantity   Total
2         Black    L-M-S    5-5-5      15
2         White     S       5          5

在我的研究中，这是最接近的解决方案，但我无法以表格形式显示它

Answer 1

$items = DB::table('item')
            ->select(DB::raw("item_id,item_color,GROUP_CONCAT(item_size SEPARATOR '-') as ItemSize,GROUP_CONCAT(item_Quantity SEPARATOR '-') as Quantity,sum(item_Quantity) as TOTAL"))
            ->groupBy('item_id','item_color')
            ->get();
