Laravel: How do I save a JSON object to MYSQL database?

Question

I want to post data from Frontend to MYSQL database in the backend using Laravel API. I tried the following code, but it outputs a 500: Internal Server Error while trying to post.

public function postOrder(Request $request)
{
    /*
     $request is a JSON Object which looks like
     {"order":{"table_id":2,"food_id":4,"status":1}}
    */

    $order = new Order();
    $order->table_id  = $request->order->table_id;
    $order->food_id   = $request->food_id;
    $order->user_id   = $request->user_id;
    $order->status    = $request->status;
    $order->save();

    return response()->json(['message' => 'Order Added'], 201);
}

Should I json_decode($request) ? How?

When I error_log($request) , here's what I get:

{"order":{"table_id":2,"food_id":4,"time":"333","status":1}}

Answer 1

You need to use json_decode() to get an associative array:

$json = '{"order":{"table_id":2,"food_id":4,"time":"333","status":1}}';

$array = json_decode($json, true);

var_dump($array['order']); //Here you can see that it is an associative array with the needed values now

Then you can create a model based on it.

$order = Order::create($array['order']);

Answer 2

那可能是解决方案：

json_decode($request, true)['order']['table_id']
