Passing ID with PHP and MySQL

Passing ID with PHP and MySQL - java

I am programming an app where a teacher logs in with a username and password. After the login a new fragment in the app opens where the teacher sees all his students in a ListView. To login I only type the username and the password. I use for this php and mysql.
My problem is that my login.php doesn't pass the ID from the teacher to the get_data.php where I do a SQL query.
login.php
<?php
session_start();
if($_SERVER['REQUEST_METHOD']=='POST'){
$username = $_POST['username'];
$password = $_POST['password'];
if($username == '' || $password == ''){
echo '';
}else{
require_once('dbConnect.php');
$sql = "SELECT ID_Teacher, username, password FROM Lehrer WHERE username='$username' and password='$password'";
mysqli_error($con);
$check = mysqli_fetch_array(mysqli_query($con,$sql));
}
if(isset($check)){
echo "success";
$_SESSION['id'] = $check['ID_Teacher'];
}else{
echo "Wrong Password or Username";
}
}else{
echo "Error, try again!";
}
?>
get_data.php
<?php
session_start();
require_once('dbConnect.php');
$sql = "SELECT Student.Name,Student.Surname FROM Student WHERE Student.ID_Teacher = {$_SESSION['id']}";
$res = mysqli_query($con,$sql);
$result = array();
while($row = mysqli_fetch_array($res))
{
array_push($result, array('Name'=>$row[0], 'Surname'=>$row[1]));
}
echo json_encode(array("result"=>$result));
mysqli_close($con);
?>

For your information, I have to retrieve the data from another web server url(http://........................./lastClock.php) and the name of the entity from the table is dclkrec(represent date) and cclktime(represent time).
Any help from you guys would be very appreciated. Thank you in advanced.

You are doing a lot of wheel reinvention here. There are tools for networking and serialising/deserialising data.
For networking I can recommend Retrofit
Working with JSON objects Gson
Try these and your life will be much easier. Trust me. It is worth investing a little time.

How can I compare my Encrypted password from database in android

Here are my Android and PHP codes available. I am able to compare the password and Login successfully if password is in form of normal String. But when I am entering the password in encrypted format I am not able to compare the password value.And therefore not able to Login Successfully.

See this link for accepted characters in URL. Persian characters are not supported as get parameters in a url. You can use http post for sending the data to the server.

first make sure that you are sending right word (persian ) from android side , maybe your java code not sending text in UTF-8 , then make sure that your server, database , and table collection are utf8_persian_ci
and change this
BufferedReader in = new BufferedReader(
new InputStreamReader(urlConnection.getInputStream()));
to this:
BufferedReader in = new BufferedReader(
new InputStreamReader(urlConnection.getInputStream(), "utf-8"),8);

I have a Android app about Public Transportation, and I have a PHP script that connects to mySQL database. This is the main.java

` Why I receive this error when I m running the app? Thanks!

HTML is not JSON, and it can not be parsed into JSONObjects. The top answer for org.json.JSONException: Value <!DOCTYPE of type java.lang.String cannot be converted to JSONObject is pretty good at explaining this further.

after logged in ,remain in home_screen until logout

I want to send the username and password to the server and it returns a response whether the username and password matches. I do not want to ask for login each time my app starts, instead I want to remain in the home_screen until I logout from my android app. How can I do this? any example will be thankfull..
package com.example.test5;
import android.content.Context;
import android.content.DialogInterface;
import android.content.SharedPreferences;
import android.content.DialogInterface.OnClickListener;
import android.os.AsyncTask;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity implements OnClickListener{
private EditText username;
private EditText password;
private Button login;
static String u;
static String p;
Context context = MainActivity.this;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
username = (EditText)findViewById(R.id.editText1);//Visibility
password = (EditText)findViewById(R.id.editText2);//Visibility
login = (Button)findViewById(R.id.button1);//Visibility
login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
u = username.getText().toString();
p = password.getText().toString();
Toast.makeText(MainActivity.this, "Checking User Login",Toast.LENGTH_SHORT).show();
new MyAsyncTask_Login(context).execute(u,p);
}
});
}
#Override
public void onClick(DialogInterface dialog, int which) {
}
}
my asynctask class
package com.example.test5;
import java.io.StringReader;
import java.util.LinkedList;
import java.util.List;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserFactory;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.content.res.XmlResourceParser;
import android.os.AsyncTask;
import android.preference.PreferenceManager;
import android.widget.Toast;
public class MyAsyncTask_Login extends AsyncTask<String, Void, String>{
public static final String MyPREFERENCES = "MyPrefs" ; //editor: never used
public static final String userName = "name";
public static final String Password = "password";
SharedPreferences sharedpreferences; //editor: never used
private Context context;
public MyAsyncTask_Login(Context context) {
this.context = context;
}
#Override
protected String doInBackground(String... params) {
String response = new Login_WebService().checkLogin(params[0], params[1]);
return response;
}
#Override
protected void onPostExecute(String result) {
String strResponse = result;
try {
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
XmlPullParser parser = factory.newPullParser();
parser.setInput(new StringReader(strResponse));
List<String> tags = new LinkedList<String>();
tags.add("valid");
for (int type = parser.next(); type != XmlResourceParser.END_DOCUMENT; type = parser.next()) {
if (type == XmlResourceParser.START_TAG) {
String name = parser.getName();
if (tags.contains(name)) {
type = parser.next();
if (parser.getText().trim().equals("1")) {
Toast.makeText(context, "logged in succesfully.",Toast.LENGTH_SHORT).show();
try {
String user = MainActivity.u;
String pass = MainActivity.p;
Intent i = new Intent(context,Home_page.class);
context.startActivity(i);
}
catch (Exception e) {
Toast.makeText(context, e.toString(),Toast.LENGTH_SHORT).show();
}
}
else {
Toast.makeText(context, "Invalid User",Toast.LENGTH_SHORT).show();
}
}
}
}
}
catch (Exception e) {
}
}
}

You can do like this:
Save your login data in shared Preferences.
When the user login:
protected void doInBackground(Activity... params) {
Activity activity = (Activity) params[0];
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(activity);//Pass activity in params o
Editor editor = prefs.edit();
editor.putString("username",u);
editor.putString("password",p);
editor.commit();
}
in on create when the user restart the app read the shared preferences:
u = prefs.getString("username", "");
p = prefs.getString("password", "");
if(u.equals("") || p.equals(""))
//user needs new login
else
//user already login
To make logout put "" in sharedpreferences.
