Why cant the code match ? PHP Response and Android - php

Question

This is my java code
public void login() {
try {
httpclient = new DefaultHttpClient();
httppost = new HttpPost("http://192.168.0.104/rocket/assign_job.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));// $Edittext_value = $_POST['Edittext_value'];
//nameValuePairs.add(new BasicNameValuePair("userName", rocketName));
Log.d("smsCode ===", smsCode);
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);
runOnUiThread(new Runnable() {
public void run() {
Log.d("PHP Response: ", response);
pDialog.dismiss();
}
});
if (response.equalsIgnoreCase("success")) {
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(UserPage.this, "Job Assigned", Toast.LENGTH_SHORT).show();
}
});
} else {
showAlert();//testing bitbuckettt
}
} catch (Exception e) {
pDialog.dismiss();
System.out.println("Exception : " + e.getMessage());
}
}
This is my PHP Code:
<?php
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
if(isset($_POST['smsCode'])){
$smsCode = $_POST['smsCode'];
$query_search = "SELECT * FROM confirmedrequest WHERE smsCode='".$smsCode."'";
$query_exec = mysqli_query($db->getConnection(),$query_search) or die(mysqli_error($db->getConnection()));
$row = mysqli_num_rows($query_exec);
if($row == 0){
echo "failed";
}else{
echo "success";
$rocketName = mysqli_real_escape_string($db->getConnection(),$_POST["userName"]);
$sql_update = "UPDATE confirmedrequest SET jobTakenBy = '$rocketName' WHERE smsCode = $smsCode ";
$sql_exec = mysqli_query($db->getConnection(),$sql_update) or die(mysqli_error($db->getConnection()));
}
}else{
echo "Empty code";
}
?>
The PHP Response in logcat is always failed even though the code matches. I have tried to debug it for several hours but still cant solve. All I want is to run the code below (response.equalsIgnoreCase("success")) when the code matches.

You have to set the headers in order to the response to be formatted in a correct way:
$db = new DB_CONNECT();
if(isset($_POST['smsCode'])){
$smsCode = $_POST['smsCode'];
$query_search = "SELECT * FROM confirmedrequest WHERE smsCode='".$smsCode."'";
$query_exec = mysqli_query($db->getConnection(),$query_search) or die(mysqli_error($db->getConnection()));
$row = mysqli_num_rows($query_exec);
if($row == 0){
http_response_code(500);
echo "failed";
}else{
http_response_code(200);
echo "success";
$rocketName = mysqli_real_escape_string($db->getConnection(),$_POST["userName"]);
$sql_update = "UPDATE confirmedrequest SET jobTakenBy = '$rocketName' WHERE smsCode = $smsCode ";
$sql_exec = mysqli_query($db->getConnection(),$sql_update) or die(mysqli_error($db->getConnection()));
}
}else{
http_response_code(400);
echo "Empty code";
}
