Spinnerコントロールを持つandroidを使用してリモートのmysqlデータベースにデータを挿入する方法

Question

私のアンドロイドアプリからリモートのmysqlデータベースにデータを送信する際に「挿入に失敗しました」というエラーがあります。これはSpinnerコントロールを持っています。私はリモートサーバー上のAPIを呼び出してインサートに接続していますが、挿入に失敗します。以下は

マイMain Activityコード

public class RCrimeActivity extends AppCompatActivity implements View.OnClickListener{ 

private EditText nop, wh; 
private Button bReport; 
private Spinner ct; 
// Progress Dialog 
private ProgressDialog pDialog; 
// JSON parser class 
JSONParser jsonParser = new JSONParser(); 

private static final String LOGIN_URL = "http://www.nigeriacrimewatch.com/ncwrcapi.php"; 
private static final String TAG_SUCCESS = "success"; 
private static final String TAG_MESSAGE = "message"; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_rcrime); 

    nop = (EditText) findViewById(R.id.nop); 
    wh = (EditText) findViewById(R.id.wh); 
    ct = (Spinner) findViewById(R.id.ct); 
    bReport = (Button) findViewById(R.id.btnReport); 
    bReport.setOnClickListener(this); 

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
    fab.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Intent homescr = new Intent(RCrimeActivity.this, MainActivity.class); 
      startActivity(homescr); 
     } 
    }); 

    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
} 

@Override 
public void onClick(View v) { 
    switch (v.getId()) { 
     case R.id.btnReport: 
      new AttemptReport().execute(); 
      // here we have used, switch case, because on login activity you may //also want to show registration button, so if the user is new ! we can go the //registration activity , other than this we could also do this without switch //case. default: 
     default: 
      break; 
    } 
} 


class AttemptReport extends AsyncTask<String, String, String> { 
    /** 
    * Before starting background thread Show Progress Dialog * 
    */ 

    boolean failure = false; 

    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 
     pDialog = new ProgressDialog(RCrimeActivity.this); 
     pDialog.setMessage("Reporting crime..."); 
     pDialog.setIndeterminate(false); 
     pDialog.setCancelable(true); 
     pDialog.show(); 
    } 

    @Override 
    protected String doInBackground(String... args) { 
     // here check for success tag 

     int success; 
     String name = nop.getText().toString(); 
     String address = wh.getText().toString(); 
     String type = ct.getSelectedItem().toString(); 


     try { 

      List<NameValuePair> params = new ArrayList<NameValuePair>(); 
      params.add(new BasicNameValuePair("nop", name)); 
      params.add(new BasicNameValuePair("wh", address)); 
      params.add(new BasicNameValuePair("ct", type)); 

      Log.d("request!", "starting"); 

      JSONObject json = jsonParser.makeHttpRequest(
        LOGIN_URL, "POST", params); 

      // checking log for json response 
      Log.d("Report attempt", json.toString()); 

      // success tag for json 
      success = json.getInt(TAG_SUCCESS); 
      if (success == 1) { 
       Log.d("Crime Reported!", json.toString()); 
       Intent ii = new Intent(RCrimeActivity.this, MapActivity.class); 
       finish(); 
       // this finish() method is used to tell android os that we are done with current //activity now! Moving to other activity 
       startActivity(ii); 
       return json.getString(TAG_MESSAGE); 
      } else { 

       return json.getString(TAG_MESSAGE); 
      } 
     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 
     return null; 
    } 

    /** 
    * Once the background process is done we need to Dismiss the progress dialog asap * 
    **/ 
    protected void onPostExecute(String message) { 
     pDialog.dismiss(); 
     if (message != null) { 
      Toast.makeText(RCrimeActivity.this, message, Toast.LENGTH_LONG).show(); 
     } 

    } 
} 

APIコード

<?php 
    error_reporting(E_ALL); 
    ini_set('display_errors',TRUE); 

    include_once "conn/nconn.php"; 


    $username=$_POST["username"]; $email=$_POST["email"]; 
    $password=$_POST["password"];   
    if (!empty($_POST)) { 
    if (empty($_POST['username']) || empty($_POST['email']) || empty($_POST['password'])) { 
    // Create some data that will be the JSON response 
    $response["success"] = 0; $response["message"] = "One or both of the fields are empty ."; 
    //die is used to kill the page, will not let the code below to be executed. It will also //display the parameter, that is the json data which our android application will parse to be //shown to the users 
    die(json_encode($response)); 
    } 
$query = " INSERT INTO gmusers (username, email, password, created) values  ('$username','$email','$password', now())"; 
    $sql1=mysql_query($query); if (!empty($sql1)) { $response["success"] = 1; 
    $response["message"] = "Registered sucessfully"; die(json_encode($response)); 
    } else{ 
    $response["success"] = 0; $response["message"] = "Failed to register"; 
    die(json_encode($response)); 
    } 
    } else{ 
    $response["success"] = 0; $response["message"] = " One or both of the fields are empty "; 
    die(json_encode($response)); 
    } 

?>

あるサーバーのAPIに問題があるように思えます。あなたのAPIスクリプトを投稿できますか
