php - 如何使用 DB::insert 作为预处理语句 LARAVEL

Question

我正在尝试使我的插入查询免受 sql 注入(inject)的影响。但是我在让它工作时遇到了问题。有任何想法吗？我已经尝试了几件事。

 $bullets = Input::get('bullet_content');
        $product_id = Input::get('product_id');
        $user_id = Input::get('user_id');
        $retailer_id = Input::get('retailer_id');
        $date = date("Y-m-d H:i:s");
        foreach ($bullets as $bullet){


            $query = "'INSERT INTO bullets(product_id, user_id,bullet_content, bullet_deleted, created_at, updated_at) 
                        VALUES('?','?','?','?','?','?')', [$product_id,$user_id,$bullet,'N',$date,$date]";


                        DB::insert($query);
        }
        return back()->with('message','Features add successfully!');

当我尝试这样做时，出现以下错误:

SQLSTATE[07002]: [Microsoft][ODBC Driver 11 for SQL Server]COUNT field incorrect or syntax error (SQL: 'INSERT INTO bullets(product_id, user_id,bullet_content, bullet_deleted, created_at, updated_at) VALUES('?','?','?','?','?','?')', [1,1,can't,'N',2017-11-10 16:28:44,2017-11-10 16:28:44])

我也试过:

 $bullets = Input::get('bullet_content');
        $product_id = Input::get('product_id');
        $user_id = Input::get('user_id');
        $retailer_id = Input::get('retailer_id');
        $date = date("Y-m-d H:i:s");
        foreach ($bullets as $bullet){


            $query = "'INSERT INTO bullets(product_id, user_id,bullet_content, bullet_deleted, created_at, updated_at) 
                        VALUES('?','?','?','?','?','?')' ";
            $values = [$product_id,$user_id,$bullet,'N',$date,$date];

                        DB::insert($query,$values);
        }
        return back()->with('message','Features add successfully!');

出现以下错误:

SQLSTATE[42000]: [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Incorrect syntax near 'INSERT INTO bullets(product_id, user_id,bullet_content, bullet_deleted, created_at, updated_at) VALUES('. (SQL: 'INSERT INTO bullets(product_id, user_id,bullet_content, bullet_deleted, created_at, updated_at) VALUES('1','1','can't','N','2017-11-10 16:33:43','2017-11-10 16:33:43')' )

您不需要引用问号。此外，您可以在循环之前初始化 $query 并将其用作 foreach 中准备好的查询:

$bullets = Input::get('bullet_content');
$product_id = Input::get('product_id');
$user_id = Input::get('user_id');
$retailer_id = Input::get('retailer_id');
$date = date("Y-m-d H:i:s");
$query = "INSERT INTO bullets (product_id, user_id,bullet_content, bullet_deleted, created_at, updated_at) 
                       VALUES (?, ?, ?, ?, ?, ?)";
foreach ($bullets as $bullet) {
    $values = [$product_id,$user_id,$bullet,'N',$date,$date];
    DB::insert($query, $values);
}
return back()->with('message','Features add successfully!');
