我正在控制器中执行查询并在我的视图中输出总费用。
继承我的疑问:
$stat = array(
'TotalCost' => DB::table('ORD_DETAIL')
->select(DB::raw('SUM(OD_QTYORD * OD_QTYUNIT * OD_COSTPRICE) as TotalCost'))
->where('OD_ORDER_NUMBER',$id)->first()
);
继承我的输出:
{{ $stat['TotalCost'] }}
但我收到错误:
htmlentities()期望参数1为字符串,给定对象(查看: F:\ view.blade.php)

您收到上述错误的原因是您的查询返回Object
。
要解决这个问题,你可以这样做:
{{ $stat['TotalCost']->TotalCost }}
或者您可以更改查询以使用Laravel的内置sum()
方法:
DB::table('ORD_DETAIL')
->where('OD_ORDER_NUMBER',$id)
->sum(DB::raw('OD_QTYORD * OD_QTYUNIT * OD_COSTPRICE'));
希望这有帮助!

将其更改为
{{ $stat['TotalCost']->TotalCost }}
维持
{{ $stat['TotalCost'] }}
将您的查询更改为
$stat = array(
'TotalCost' => DB::table('ORD_DETAIL')
->select(DB::raw('SUM(OD_QTYORD * OD_QTYUNIT * OD_COSTPRICE) as TotalCost'))
->where('OD_ORDER_NUMBER',$id)->lists('TotalCost')->first();
);
