제품 ID, 설명, 수량 및 총 가격 배열을 데이터베이스에 저장해야합니다. 나는 json 파서 클래스와 userfunctions 클래스를 정의했다. 이 전에는 각 변수에 대해 Json의 단일 값만 보냈습니다. 내 현재 코드를 기반으로 배열로 보낼 문제가 있습니다. 아래 코드는 제품 배열입니다.안드로이드에서 JSON 배열을 PHP로 보내십시오

이것은 json 파서를 사용하여 값을 PHP로 보내야하는 사용자 함수 클래스입니다. 그러나 배열로 보낼 변환 할 생각이 없어.
public class UserFunctions {
private JSONParser jsonParser;
//URL of the PHP API
private static String orderURL = "http://www.xxx.com/xxxx_login_api/";
private static String order_tag = "order";
// constructor
public UserFunctions(){
jsonParser = new JSONParser();
}
/**
* Function store order details
**/
public JSONObject orderDetails(String username, String pid, String products, String quantity, String totalprice, String finalprice) {
// Building Parameters
List params = new ArrayList();
params.add(new BasicNameValuePair("tag", billing_tag));
params.add(new BasicNameValuePair("pid", pid));
params.add(new BasicNameValuePair("username", username));
params.add(new BasicNameValuePair("products", products));
params.add(new BasicNameValuePair("quantity", quantity));
params.add(new BasicNameValuePair("totalprice", totalprice));
params.add(new BasicNameValuePair("final", finalprice));
JSONObject json = jsonParser.getJSONFromUrl(orderURL,params);
return json;
}
}
}
JSON 파서 클래스입니다.
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
public JSONObject getJSONFromUrl(String url, List params) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
Log.e("JSON", json);
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {

내가
표 아래와 같이 MySQL의 테이블에 배열 데이터를 저장해야합니다 열 view_order : OrderID를, 제품 ID (외부 키), 수량, TOTAL_PRICE, final_final
나는 방법을 알고 싶은 JSON을 편집하고 PHP 코드를 작성하여 JSON을 디코딩하고 데이터베이스에 저장하십시오. 감사합니다
