I am trying to compare the value from EditText in Android and compare it with a value from MySQL with PHP.
Here is my java code:
public class DisplayInformation extends MainActivity {
private Button confirmCode;
private ProgressDialog pDialog;
JSONParser jsonParser = new JSONParser();
HttpPost httppost;
StringBuffer buffer;
HttpResponse response;
HttpClient httpclient;
EditText smsCode;
List<NameValuePair> nameValuePairs;
private static final String LOGIN_URL = "http://10.0.2.2/callarocket/confirmedRequest.php";
private static final String TAG_SUCCESS = "success";
private static final String TAG_MESSAGE = "message";
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.second_screen);
TextView textView1 = (TextView)findViewById(R.id.textView1);
TextView textView2 = (TextView)findViewById(R.id.textView2);
TextView textView3 = (TextView)findViewById(R.id.textView3);
TextView textView4 = (TextView)findViewById(R.id.textView4);
TextView textView5 = (TextView)findViewById(R.id.textView5);
textView1.setText(getIntent().getStringExtra("displayName"));
textView2.setText(getIntent().getStringExtra("displayContact"));
textView3.setText(getIntent().getStringExtra("displayAddress"));
textView4.setText(getIntent().getStringExtra("displayStore"));
textView5.setText(getIntent().getStringExtra("displayRequest"));
smsCode = (EditText) findViewById(R.id.smscode);
confirmCode = (Button)findViewById(R.id.confirmsmscode);
//confirmCode.setOnClickListener(this);
confirmCode.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
pDialog = ProgressDialog.show(DisplayInformation.this, "",
"Validating Code...", true);
new Thread(new Runnable() {
public void run() {
login();
}
}).start();
}
});
}
// public void onClick(View v) {
// TODO Auto-generated method stub
//new CreateUser().execute();
//}
public void login(){
try{
httpclient=new DefaultHttpClient();
httppost= new HttpPost("http://10.0.2.2/callarocket/check_code.php"); // make sure the url is correct.
//add your data
nameValuePairs = new ArrayList<NameValuePair>(1);
// Always use the same variable name for posting i.e the android side variable name and php side variable name should be similar,
//int smsNum = Integer.parseInt(smsCode.getText().toString());
nameValuePairs.add(new BasicNameValuePair("smsCode",smsCode.getText().toString())); // $Edittext_value = $_POST['Edittext_value'];
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
//Execute HTTP Post Request
response=httpclient.execute(httppost);
ResponseHandler<String> responseHandler = new BasicResponseHandler();
final String response = httpclient.execute(httppost, responseHandler);
System.out.println("Response : " + response);
runOnUiThread(new Runnable() {
public void run() {
//tv.setText("Response from PHP : " + response);
pDialog.dismiss();
}
});
if(response.equalsIgnoreCase("Code Found")){
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(DisplayInformation.this,"Code Matched", Toast.LENGTH_SHORT).show();
}
});
//startActivity(new Intent(AndroidPHPConnectionDemo.this, UserPage.class));
}else{
showAlert();
}
}catch(Exception e){
pDialog.dismiss();
System.out.println("Exception : " + e.getMessage());
}
}
public void showAlert(){
DisplayInformation.this.runOnUiThread(new Runnable() {
public void run() {
AlertDialog.Builder builder = new AlertDialog.Builder(DisplayInformation.this);
builder.setTitle("Error.");
builder.setMessage("Invalid Code.")
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
AlertDialog alert = builder.create();
alert.show();
}
});
}
}
And here is my PHP code:
<?php
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
//$smsCode = 8044;
$smsCode = isset($_POST['smsCode']);
$query_search = "SELECT * FROM userrequests WHERE smsCode='".$smsCode."'";
$query_exec = mysqli_query($db->getConnection(),$query_search) or die(mysqli_query());
$row = mysqli_num_rows($query_exec);
//echo $rows;
if($row == 0) {
echo "Invalid SMS Code";
}
else {
//Authentication code is correct
echo "Code matched";
}
?>
There is no error but it always show "Invalid Code" although the code entered is correct. How do I fix this ?
