PHP / Laravel：如何在PHP中创建JSON时插入新的json字段？

Question

I am returning JSON to my frontend like this:

    public function newFlavorOrders()
    {
        $orders = request()->user()->ordersPaid;
        return response()->json(['flavor_orders' => $orders]);
    }

and right now, that returns this to the frontend:

{ orders: [
   {
     color: "Green"
     size: "Large",
     order_products: [ {'itemNum': 3, 'imgUrl': "zera.jpg"}, {'itemNum': 5, 'imgUrl': "murto.jpg"} ]
   },
   {
     color: "Blue"
     size: "Large",
     order_products: [ {'itemNum': 3, 'imgUrl': "mcue.jpg"}, {'itemNum': 5, 'imgUrl': "cloa.jpg"} ]
    }
  ]
}

But I want to alter the controller PHP function to add a field to each order_products item. I have the imgURL, but I want to add a processedImgUrl and stub it with true right now. How can I add the field to the above php function when returning the JSON?

Without the dataset this may not be exactly accurate but the way to do this is either to perform an array push or do a foreach loop and add create the index to be appended.

For example:

public function newFlavorOrders()
{   
    // CREATE A NEW ARRAY TO ADD THE MODIFIED DATA TO
    $modified = array();
    $orders = request()->user()->ordersPaid;

    // LOOP THROUGH AND ADD THE VALUE TO THE ITERATION
    foreach($orders as $row) {
        foreach($row['order_products'] as $val){
            $modified = $val;
            if(!empty($val['imgUrl'])){
                $modified['processedImgUrl'] = TRUE;
            } else {
                $modified['processedImgUrl'] = FALSE;
            }
        }
    }

    return response()->json(['flavor_orders' => $modified]);
}

Something like this should work. You need to loop through the first array, then get down to the next level array (order_products).
