I am having an issue where my json object array isn't passing the values. I know they are there, but I can't get them to pass into the variables in my android app.
The Java function to handle the JSONObject:/**
* Function to get all userlogs
**/
public JSONObject getUserLogs(String userid){
// userlogs JSONArray
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("tag", getUserLogs_tag ));
params.add(new BasicNameValuePair("userid", userid));
JSONObject json = jsonParser.getJSONFromUrl(getAllUserLogs,params);
return json;
}
Here is the Java do in backgrond:
protected String doInBackground(String... args) {
//List<NameValuePair> params = new ArrayList<NameValuePair>();
DatabaseHandler db = new DatabaseHandler(getApplicationContext());
HashMap<String,String> user = new HashMap<String, String>();
user = db.getUserDetails();
userid = user.get("uid");
UserFunctions userFunction = new UserFunctions();
JSONObject json = userFunction.getUserLogs(userid);
Log.d("All userlogs: ", json.toString());
// return json;
try {
if (json.getString(KEY_SUCCESS) != null) {
userlogs = json.getJSONArray(KEY_USERLOGS);
// looping through All Products
for (int i = 0; i < userlogs.length(); i++) {
JSONObject c = userlogs.getJSONObject(i);
// Storing each json item in variable
String userID = c.getString(KEY_USERID);
String medname = c.getString(KEY_MEDNAME);
String medtaken = c.getString(KEY_MEDTAKEN);
String tabsleft = c.getString(KEY_TABSLEFT);
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(KEY_USERID, userid);
map.put(KEY_MEDNAME, medname);
map.put(KEY_MEDTAKEN, medtaken);
map.put(KEY_TABSLEFT, tabsleft);
// adding HashList to ArrayList
logList.add(map);
}
}
}
catch (JSONException e) {
e.printStackTrace();
}
return null;
}
Here is the results:

The PHP:
else if ($tag == 'getUserLogs') {
$userid = $_POST['userid'];
//Special case (normally conntections handled in functions/config or connect)
$link = new mysqli($host, getDBuser(), getDBpassword(), getDBname());
/* check connection */
if (mysqli_connect_errno()) {
$response["error"] = 1;
$response["error_msg"] = mysqli_connect_error();
echo json_encode($response);
}
$query = "SELECT * FROM userlog WHERE userid = '$userid'";
$result = mysqli_query($link, $query);
$row_cnt = mysqli_num_rows($result);
//If results, then
if( $row_cnt > 0){
$response["userlogs"] = array();
while($row = mysqli_fetch_array($result, MYSQLI_BOTH)){
$userlog = array();
$userlog["userlogs"]["userid"] = $row["userid"];
$userlog["userlogs"]["medname"] = $row["medname"];
$userlog["userlogs"]["medtaken"] = $row["medtaken"];
$userlog["userlogs"]["tabsleft"] = $row["tabsleft"];
array_push($response["userlogs"], $userlog);
}
$response["success"] = 1;
echo json_encode($response);
mysqli_close($link);
}
else {
// userlogs not found
// echo json with error = 1
$response["error"] = 1;
$response["error_msg"] = "No Userlogs found";
echo json_encode($response);
}
}
else {
$response["error"] = 3;
$response["error_msg"] = "JSON ERROR";
echo json_encode($response);
}
}
Any suggestions?
