單選按鈕的值不能存儲到字符串和mysql的

Question

保存在我的應用程序，在註冊時，用戶可以通過使用單選按鈕（RadioGroup中）

選擇學生或店老闆的角色，他們選擇了它之後並填寫註冊表格，所有數據包括role都應該存入mysql。

遺憾的是，只有name，email，username和password成功保存，但role不能存儲。

這是我的java文件：

package com.androidhive.dashboard; 

import java.util.ArrayList; 
import java.util.List; 

import org.apache.http.NameValuePair; 
import org.apache.http.message.BasicNameValuePair; 
import org.json.JSONObject; 

import android.app.Activity; 
import android.app.AlertDialog; 
import android.content.DialogInterface; 
import android.content.Intent; 
import android.os.AsyncTask; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.RadioButton; 
import android.widget.RadioGroup; 
import androidhive.dashboard.R; 

public class Register extends Activity { 

JSONParser jsonParser = new JSONParser(); 
EditText inputName; 
EditText inputUsername; 
EditText inputEmail; 
EditText inputPassword; 
RadioGroup rgroup; 
Button button3; 
int success = 0; 
String role = ""; 

private static String url_register_user = "http://192.168.1.5/database/add_user.php"; 
private static final String TAG_SUCCESS = "success"; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.register_layout); 

    inputName = (EditText) findViewById(R.id.nameTextBox); 
    inputUsername = (EditText) findViewById(R.id.usernameTextBox); 
    inputEmail = (EditText) findViewById(R.id.emailTextBox); 
    inputPassword = (EditText) findViewById(R.id.passwordTextBox); 

    Button button3 = (Button) findViewById(R.id.regSubmitButton); 

    final RadioGroup rgroup = (RadioGroup)findViewById(R.id.roleRgroup); 
    final RadioButton student = (RadioButton)findViewById(R.id.studButton); 
    final RadioButton shopowner = (RadioButton)findViewById(R.id.shopownerButton); 

    button3.setOnClickListener(new View.OnClickListener() {   
     public void onClick(View view) { 

      String name = inputName.getText().toString(); 
      String username = inputUsername.getText().toString(); 
      String email = inputEmail.getText().toString(); 
      String password = inputPassword.getText().toString(); 

      if (rgroup.getCheckedRadioButtonId() == student.getId()) 
      { 
       role = "Student"; 
      } 

      else if(rgroup.getCheckedRadioButtonId() == shopowner.getId()) 
      { 
       role = "ShopOwner"; 
      } 

      if (name.contentEquals("")||username.contentEquals("")||email.contentEquals("")||password.contentEquals("")) 
      { 
       AlertDialog.Builder builder = new AlertDialog.Builder(Register.this); 

       builder.setMessage(R.string.nullAlert) 
        .setTitle(R.string.alertTitle); 

       builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 

        } 
       }); 

       AlertDialog dialog = builder.show(); 
      } 
      else 
      { 
       new RegisterNewUser().execute(); 
      }   
     } 
    }); 
} 

    class RegisterNewUser extends AsyncTask<String, String, String>{ 
    protected String doInBackground(String... args) { 
     String name = inputName.getText().toString(); 
     String username = inputUsername.getText().toString(); 
     String email = inputEmail.getText().toString(); 
     String password = inputPassword.getText().toString(); 

     List<NameValuePair> params = new ArrayList<NameValuePair>(); 
     params.add(new BasicNameValuePair("name", name)); 
     params.add(new BasicNameValuePair("username", username)); 
     params.add(new BasicNameValuePair("email", email)); 
     params.add(new BasicNameValuePair("password", password)); 
     params.add(new BasicNameValuePair("role", role)); 

     JSONObject json = jsonParser.makeHttpRequest(url_register_user, 
          "GET", params); 

     Log.d("Send Notification", json.toString()); 

     try 
      { 
        int success = json.getInt(TAG_SUCCESS); 

        if (success == 1) 
        { 

         if (role.contentEquals("Student")) 
         { 
          Intent i = new Intent(getApplicationContext(), StudMain.class); 
          startActivity(i); 
          finish(); 
         } 
         else if ((role.contentEquals("Shop Owner"))) 
         { 
          Intent i = new Intent(getApplicationContext(), ShopMain.class); 
          startActivity(i); 
          finish(); 
         } 
         else 
         { 
          AlertDialog.Builder builder = new AlertDialog.Builder(Register.this); 

          builder.setMessage(R.string.roleNullAlert) 
           .setTitle(R.string.alertTitle); 

          builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() { 
           public void onClick(DialogInterface dialog, int id) { 

           } 
          }); 

          AlertDialog dialog = builder.show(); 
         } 

        } 

        else 
        { 

        } 
      } 

      catch (Exception e) 
      { 
        e.printStackTrace(); 
      } 
      return null; 
      } 
    } 
} 

和PHP文件：

<?php 

// array for JSON response 
$response = array(); 
// include db connect class 
require_once __DIR__ . '/db_connect.php'; 

// connecting to db 
$db = new DB_CONNECT(); 

// check for required fields 
if (isset($_GET['name']) && isset($_GET['username']) && isset($_GET['email']) && isset($_GET['password']) && isset($_GET['role'])) { 

$name = $_GET['name']; 
$username = $_GET['username']; 
$email = $_GET['email']; 
$password = $_GET['password']; 
$role = $_GET['role']; 

// mysql inserting a new row 
$result = mysql_query("INSERT INTO register(name, username, email, password) VALUES('$name', '$username', '$email', '$password', '$role')"); 

// check if row inserted or not 
if ($result) { 
    // successfully inserted into database 
    $response["success"] = 1; 
    $response["message"] = "You are successfully registered to MEMS."; 

    // echoing JSON response 
    echo json_encode($response); 
} 
else { 
    // failed to insert row 
    $response["success"] = 0; 
    $response["message"] = "Oops! An error occurred."; 

    // 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); 
} 
?> 

除了這兩個文件，是不是會影響RadioGroup中的功能，任何可能的因素是什麼？

謝謝回答.. =）

你的MySQL插入查詢缺少的「角色」，這就是爲什麼你不能保存。

$result = mysql_query("INSERT INTO register(name, username, email, password) VALUES('$name', '$username', '$email', '$password', '$role')"); 

將其更改爲

$result = mysql_query("INSERT INTO register(name, username, email, password,role) VALUES('$name', '$username', '$email', '$password', '$role')");
