如何將DB :: insert用作准備好的語句LARAVEL

Question

我試圖使我的插入查詢免受SQL注入的影響。 但是我在使它起作用方面遇到問題。 有任何想法嗎？ 我已經嘗試了幾件事。

 $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!');

當我嘗試此操作時，出現以下錯誤：

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])

我也嘗試過：

 $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!');

並得到以下錯誤：

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')' )

您無需引用問號。 此外，您可以在循環之前初始化$ query並將其用作foreach中的准備查詢：

$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!');
