I'am not able to understand why is this happening please Guide me.
My PHP File
<?php
require 'DbConnect.php';
$i=1;
$Password = $_POST["password"];
$Email = $_POST["email"];
$Pin = $_POST["pin"];
//$KeyCode = $_REQUEST["key"];
if((isset($_POST["password"])) && (isset($_POST["email"])) && (isset($_POST["pin"])))
{
$query4 = ("SELECT seller_id, name, email, password, verification_Pin, verification_Code, created_Date FROM `seller` WHERE email = '$Email'");
$query_run = mysql_query($query4);
$row=mysql_fetch_row($query_run);
$int=$row[0];
$strName=$row[1];
$strEmail=$row[2];
$strPwd=$row[3];
$strPin=$row[4];
echo $Pin;
echo $Password;
echo $Email;
echo $int;
echo $strEmail;
echo $strPwd;
echo $strPin;
if(($Email==$strEmail) && ($Password==$strPwd) && ($Pin==$strPin))
{
global $i;
$i=2;
$id=updateValidation($int);
echo $id;
if($id==1)
{
echo "Verified";
}
else
{
echo "Not Verified";
}
}
else
{
echo "Invaild";
}
}
else
{
echo "Values not set";
}
function updateValidation($sid)
{
global $i;
if($i==2)
{
echo "Inside Update vAlidation";
$queryUpdate = ("UPDATE `seller` SET verification_Pin = 0, verification_Code = 'Verified', created_Date = CURDATE() where seller_id='$sid'");
if(mysql_query($queryUpdate))
{
return 1;
}
else
{
return 2;
}
}
else
{
echo "i not 2";
}
}
?>
My Class file:
Button ok = (Button) myDialog
.findViewById(R.id.button1);
et_pin = (EditText) myDialog
.findViewById(R.id.editText1);
ok.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Toast.makeText(getApplicationContext(),
"CLICKED OK", Toast.LENGTH_LONG).show();
pin = et_pin.getText().toString();
Toast.makeText(
getApplicationContext(),
"email,pass,pin= " + str1 + "," + str2
+ "," + pin, Toast.LENGTH_LONG)
.show();
new App_pin_Task().execute(FILENAME_pin);
// Intent intent = new
// Intent(Dealer_details.this,
// Login.class);
// startActivity(intent);
}
});
public class App_pin_Task extends AsyncTask<String, Integer, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@SuppressLint("NewApi")
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
Toast.makeText(getApplicationContext(),
"Inside App_pin_Task post Execute(Result)=" + result,
Toast.LENGTH_LONG).show();
if (result.contains("Invalid")) {
et_pin.setText("");
} else {
Intent myIntent = new Intent(Login.this, UserActivity.class);
startActivity(myIntent);
}
}
@Override
protected void onProgressUpdate(Integer... values) {
// TODO Auto-generated method stub
super.onProgressUpdate(values);
}
@Override
protected String doInBackground(String... params) {
// String is = null;
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"http://animsinc.com/verifyEmail.php");
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
4);
nameValuePairs.add(new BasicNameValuePair("email", str1));
nameValuePairs.add(new BasicNameValuePair("password", str2));
nameValuePairs.add(new BasicNameValuePair("pin", pin));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
httpclient.execute(httppost);
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = EntityUtils.toString(entity);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
}
return is;
}
}
What is being returned with
$Password = $_REQUEST["password"];
$Email = $_REQUEST["email"];
$Pin = $_REQUEST["pin"];
$KeyCode = $_REQUEST["key"];
Your server configuration may have this option disabled and not returning anything.
You shouldn't use $_REQUEST anyway because you can never be sure where the data is actually coming from: $_POST, $_GET or $_cookie.
try this!
Change this
$Password = $_REQUEST["password"];
$Email = $_REQUEST["email"];
$Pin = $_REQUEST["pin"];
$KeyCode = $_REQUEST["key"];
to for Get Request
$Password = $_GET["password"];
$Email = $_GET["email"];
$Pin = $_GET["pin"];
$KeyCode = $_GET["key"];
or for Post Request
$Password = $_POST["password"];
$Email = $_POST["email"];
$Pin = $_POST["pin"];
$KeyCode = $_POST["key"];
or
"SELECT seller_id, name, email, password, verification_Pin,
verification_Code, created_Date FROM seller WHERE email = '".$Email."'"
Complementing the answer from fayeq-ali-khan I would also do the following;
First use post and add html special character for security.
htmlspecialchars => Convert special characters to HTML entities
$Password = htmlspecialchars($_POST['password'],ENT_QUOTES);
$Email = htmlspecialchars($_POST['email'],ENT_QUOTES);
$Pin = htmlspecialchars($_POST['pin'],ENT_QUOTES);
$KeyCode = htmlspecialchars($_POST['key'],ENT_QUOTES);
Also on your android activity and before you send the string it would be a good idea to trim the value to make sure that you are not transmitting empty character that can also mess up with the PHP
nameValuePairs.add(new BasicNameValuePair("email", str1.trim()));
nameValuePairs.add(new BasicNameValuePair("password", str2.trim()));
nameValuePairs.add(new BasicNameValuePair("pin", pin.trim()));
I hope it help you with something
