我有一個字符串數組，其中包含值字符串array = {6,37,38,837,7,...}，我也使用了一些字符串值。如何發送字符串數組到服務器使用php在android
我想將所有字符串值和字符串數組發送到位於服務器端的數據庫。當我點擊提交按鈕時，數據將存儲在表格中。
在PHP方面，我想讀取這個數組，因爲它是，我會在後臺做的其他事情意味着PHP方面。看到我的下面的代碼，那麼你會得到它所說的。
這裏是我的代碼：
public class Hotels extends Activity {
// Declare Variables
JSONArray jsonarray = null;
private static final String TAG_ID = "id";
public static final String TAG_NAME = "name";
public static final String TAG_LOCATION = "location";
public static final String TAG_DESC = "description";
String f_date, l_date;
ArrayList<String> ne = new ArrayList<String>();
public Set<String> interestList = new HashSet<String>();
public Set<String> interestlist = new HashSet<String>();
//public String[] hotel_id = new String[0];
ProgressDialog loading;
ListView list;
Button booknow;
private ArrayList<Product> itemlist;
Product product;
static String Array = "MyHotels";
View view;
CheckBox click;
String hotel = "http://app.goholidays.info/getHotelData.php";
String booking = "http://app.goholidays.info/insertIntoBooking.php";
SharedPreferences sp;
SharedPreferences.Editor editor;
@Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.all_item_layout);
product = new Product();
itemlist = new ArrayList<Product>();
new ReadJSON().execute();
click = (CheckBox) findViewById(R.id.mycheckbox);
booknow = (Button) findViewById(R.id.bookhotel);
product = new Product();
list = (ListView) findViewById(R.id.myimagelist);
Calendar c = Calendar.getInstance();
System.out.println("Current time => " + c.getTime());
SimpleDateFormat df = new SimpleDateFormat("yyyyMMddHHmmss");
sp = PreferenceManager.getDefaultSharedPreferences(Hotels.this);
editor = sp.edit();
final String user_id = sp.getString("id", TAG_ID);
final String start_date = sp.getString("start_date", f_date);
final String end_date = sp.getString("end_date", l_date);
final String chk_status = df.format(c.getTime());
booknow.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String[] hotel_id = new String[ne.size()]; //here is my string array{1,2,2,3,4,...} i want send it to server as it is.
hotel_id = ne.toArray(hotel_id);
for(int i = 0; i < hotel_id.length ; i++){
Log.d("string is",(String)hotel_id[i]);
}
new BackTask().execute();
}
});
}
..........
class BackTask extends AsyncTask<String, Void, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected String doInBackground(String... params) {
List<NameValuePair> param = new ArrayList<NameValuePair>();
param.add(new BasicNameValuePair("start_date", start_date));
param.add(new BasicNameValuePair("end_date", end_date));
param.add(new BasicNameValuePair("chk_status", chk_status));
for(String value: hotel_id){
param.add(new BasicNameValuePair("hotel_id[]",value));
}
param.add(new BasicNameValuePair("user_id", user_id));
JSONObject json = jsonParser.makeHttpRequest(booking, "POST", param);
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully book a hotels
Intent i = new Intent(getApplicationContext(), HomePage.class);
startActivity(i);
// closing this screen
finish();
} else {
// failed to book hotels
Log.d("failed to book hotel", json.toString());
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if(result != null){
Toast.makeText(getApplicationContext(), "Book Success", Toast.LENGTH_SHORT).show();
}
}
}
BackTask lg = new BackTask();
//here the array is converted in to string
lg.execute(start_date, end_date, chk_status, String.valueOf(hotel_id), user_id);
}
}
看到我的logcat
JSON Parser: Error parsing data org.json.JSONException: Value <br of type java.lang.String cannot be converted to JSONObject
這裏是我的PHP代碼
<?php
require "db_connect.php";
$response = array();
// check for required fields
if (isset($_POST['start_date']) && isset($_POST['end_date']) && isset($_POST['user_id']) && isset($_POST['hotel_id']) && isset($_POST['chk_status'])) {
$start_date= $_POST["start_date"];
$end_date= $_POST["end_date"];
$user_id= $_POST["user_id"];
$hotel_id= $_POST["hotel_id"];
$chk_status= $_POST["chk_status"];
$result= mysqli_query("insert into tb_booking(start_date,end_date,user_id,hotel_id,chk_status) values ('$start_date','$end_date','$user_id','$hotel_id','$chk_status')");
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "Hotel book successfully.";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.Please select hotels";
// echoing JSON response
echo json_encode($response);
}
}else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
}
?>
請幫我解決這個問題。
代碼太多。你真的期望有人經歷這一切嗎？ – m02ph3u5
