Question

您好，我正在尝试使用api将多个记录插入表中。但是我收到诸如“连接数据库错误”之类的错误。我该怎么解决。

下面是我的代码

public function addToCart(){
   $input =  Input::all();
   $data['status'] = 0;
   $data['error'] = true;
   if(isset($input['user_id']) && array_filter($input['cart']) > 0 ){

        foreach($input['cart'] as $key => $val){


          if(!empty($val['quantity']) && !empty($val['price']) && !empty($val['sku']) && !empty($val['qrcode'])  && !empty($val['product_id']))

            {

                $totalPrice = $val['quantity']* $val['price'];

                    $cartId = DB::table('jocom_cart')->insertGetId(array(
                    'user_id'   => $input['user_id'],
                    'product_id'      => $val->product_id,
                    'sku'      => $val->sku,
                    'quantity'       => $val->quantity,
                    'price' => $val->price,
                    'total_price' => $totalPrice,
                     'qrcode' => $val->qrcode
                    )
                );

        }

    else{
        $data['message'] = 'All field are required.';

    }
    return Response::json($data);   
}

创建一个数据数组，然后将该数组传递给insert function

尝试避免循环查询

$insertRecord = [];
foreach($input['cart'] as $key => $val){
    if(!empty($val['quantity']) && !empty($val['price']) && !empty($val['sku']) && !empty($val['qrcode'])  && !empty($val['product_id']))
    {
        $totalPrice = $val['quantity']* $val['price'];
        $insertRecord[$key] = ['user_id'=>$input['user_id'],'product_id' => $val->product_id,... ,... ,...]; All your column with value
    }
}
if(!empty($insertRecord)){
   Model::insert($insertRecord); // Eloquent approach
   DB::table('table')->insert($insertRecord); // Query Builder approach
}
