iOS アプリ用の API を構築しており、mySQL データを JSON 文字列に変換して処理しようとしています。目的の出力には、顧客の名前や住所などの最上位の注文の詳細と、注文された製品のサブ配列が必要です。

必要な両方のテーブルにかなりの数のフィールドがあり、すべてのフィールドが必要です。これを行うスクリプトを作成しましたが、出力が JSON バリデーターで不正な形式であると報告されています。

これが私のコードです:

$orders = $db->get_results("SELECT ords.serial as ID, cust.title, cust.name, cust.surname, cust.address, cust.address2, cust.town, cust.county, cust.postcode, cust.phone, cust.height, cust.weight, cust.houseType, cust.parking, cust.access, ords.furnitureRem, ords.furnitureRemDetails, ords.comments FROM orders as ords JOIN customers as cust ON ords.customerid = cust.serial JOIN order_detail as odeet ON ords.serial = odeet.orderid JOIN `user` as us ON us.id = ords.user_id  WHERE us.id='".$_REQUEST['userID']."' GROUP BY ords.serial ORDER BY cust.serial DESC"); 

$json_response = array(); //Create an array
foreach ( $orders as $row )
{
    $row_array = array();
    $row_array[] = $row;        
    $ord_id = $row->ID;  

    $orders2 = $db->get_results("SELECT * FROM order_detail as ord
    JOIN products as prod ON ord.productid = prod.id
    WHERE ord.orderid = ".$ord_id);
    foreach ( $orders2 as $vorder2 ) {
    {
        $row_array['products'][] = $vorder2;
    }
    array_push($json_response, $row_array); //push the values in the array
}
echo json_encode($json_response);
}

現在の出力は次のようになります。

私はこれに困惑しています。それとも、きれいな JSON を出力するために、データセットの各フィールドを項目化する必要がありますか?

質問からはそれほど明確ではありませんが、次のようなものが必要だと思います。

[
  {
    "ID": 123,
    ...
    "products": [
      {
        "foo": "bar"
      },
      {
        "foo": "baz"
      }
    ]
  },
  {
    ...
  }
]

これが正しい場合は、コードを少しリファクタリングする必要があります。まず、products配列を配列内に配置する必要があります。これは、$row_array配列を含むべきで$rowはありません。$rowはパブリック プロパティを持つオブジェクトのように見えるため、配列にキャストし$rowて次のように割り当てることができ$row_arrayます。

$row_array = (array) $row;

ご覧のとおり、$row_arrayをラップする は$row必要あり$row_arrayません$row

array_push()最後に、配列の最後に 1 つの要素のみをプッシュする必要がある場合は、使用を避けてください。

$json_response[] = $row_array;

よりも高速ですarray_push()

最後に必要なコードは次のとおりです。

$orders = $db->get_results(("SELECT ords.serial as ID, cust.title, cust.name, cust.surname, cust.address, cust.address2, cust.town, cust.county, cust.postcode, cust.phone, cust.height, cust.weight, cust.houseType, cust.parking, cust.access, ords.furnitureRem, ords.furnitureRemDetails, ords.comments FROM orders as ords JOIN customers as cust ON ords.customerid = cust.serial JOIN order_detail as odeet ON ords.serial = odeet.orderid JOIN `user` as us ON us.id = ords.user_id  WHERE us.id='".$_REQUEST['userID']."' GROUP BY ords.serial ORDER BY cust.serial DESC");

$json_response = array();
foreach ( $orders as $row ) {
    $row_array = (array) $row;
    $ord_id = $row->ID;

    $orders2 = $db->get_results("SELECT * FROM order_detail as ord
        JOIN products as prod ON ord.productid = prod.id
        WHERE ord.orderid = ".$ord_id);
    foreach ( $orders2 as $vorder2 ) {
        $row_array['products'][] = $vorder2;
    }
    $json_response[] = $row_array;
}
echo json_encode($json_response);
