Hi all, I'm trying to post login information to a php page which in turn logs in and send a response back for the device to read. The problem is that even with the correct combination of username and password, i still get failure as response from the php instead of success.
Here are my codes:
Deviceside:
String userString = userField.getText();
String passField.getText();
URLEncodedPostData encodedData = new URLEncodedPostData(null, false);
encodedData.append("username", userString);
encodedData.append("password", passString);

HttpConnection connection = (HttpConnection)Conector.open(url);
Connection.setRequestMethod("POST");
Connection.setRequestProperty("Content-Type", "application/xwww-form-urlencoded");
Connection.setRequestProperty("Content-Length", (new Integer(postData.length)).toString());
OutputStream requestOutput = connection.openOutputStream();
RequestOutput.write(postData);
RequestOutput.close();

Int responseCode = connection.getResponseCode();
If (responseCode == HttpConnection.HTTP_OK) {
// get the response from server
}

Server side:
$user = $_POST['username'];
$password = $_POST['password'];
$select_user = mysql_query("SELECT * from users where username = '$user' and password = '$password'");

If (mysql_num_rows($select_user) != 0) {
echo ("Success");
}
else {
echo ("Failure");
}
}

I think the problem is that m not posting the values properly but i can't seem to identify where the flaw is. Please help

first: do not execute networking on the event thread. see http://supportforums.blackberry.com/t5/Java-Development/What-is-the-Event-Thread/ta-p/446865

i would suggest that you check your output using a local proxy such as tcpmon.

The networking is not on the event thread... I just extracted the code from my posthttprequest thread. I will try to check the output. Thanks

Hi 

Pleas try this code. put your username password value as a parameter.

	public static boolean useraccount(String username,String password)
    {
	    boolean ret = false;
        InputStream inputStream = null;
        HttpConnection httpConnection = null;
    
        try
        {
            
            StringBuffer returnStringBuffer = new StringBuffer();
            String returnString = new String();
            

            String desiredEncoding = "ISO-8859-1";


            URLEncodedPostData params = new URLEncodedPostData(URLEncodedPostData.DEFAULT_CHARSET, true);
        
          
            params.append("username", username);
            params.append("password", password);
               
            String url = "<YOUR URL>" + params.toString();                     
                                       
            //Connecting to Server
            httpConnection = (HttpConnection)Connector.open(url);
            
            inputStream = httpConnection.openDataInputStream();
            
            if(httpConnection.getResponseCode() == HttpConnection.HTTP_OK)
            {
                int ch;
            
                //Process Response
                
                // check header field for a specific encoding
                String contenttype = httpConnection.getHeaderField("Content-Type");
                if (contenttype != null)
                {
                    contenttype = contenttype.toUpperCase();
                    if (contenttype.indexOf("UTF-8") != -1)
                    {
                        desiredEncoding = "UTF-8";
                    }
                }
            
                // get an inputstreamreader to handle utf-8 data
                InputStreamReader isr = new InputStreamReader(inputStream,desiredEncoding);
            
                while ((ch = isr.read()) != -1) 
                {
                    returnStringBuffer.append((char) ch);
                }
                    
                inputStream.close();
                httpConnection.close();
                inputStream = null;
                httpConnection = null;
                returnString = returnStringBuffer.toString();

                // examine return string
                if (returnString.indexOf("SUCCESS") != -1)
                {
                    ret = true;
                }
                return ret;
            }
            inputStream.close();
            httpConnection.close();
            inputStream = null;
            httpConnection = null;
            //Bad Transaction.
            return ret;
        }
        catch (Exception e)
        {
            System.out.println("Error occurred in ProcessTransaction(,)\n" + e.toString());
            return ret;
        }
        finally
        {
            try
            {
                if (inputStream != null)
                    inputStream.close();
                if (httpConnection != null)
                    httpConnection.close();
            }
            catch (Exception ee)
            {
            }
        }
   }

@pankajes12; thanks for the code... Same output though. Its returning false.

If it'll help, here's the link to the php file http://www.onadabayi.x10.mx/SociaLink/test.php
A form that posts to the test.php is located at www.onadabayi.x10.mx/SociaLink/login.html

A valid username=daniel and password= daniel

[pankajace12]

HI

Can you check, what url is exactly passed to server?

Thanks

[Oloruntoba]

Yes... "http://www.onadabayi.x10.mx/test.phpusername=daniel&password=daniel"

[pankajace12]

hi, if you will put it on browser. it is also not working.

So confirm your url first.

Thanks

This is not the same as sending a POST request with username/password, just saying.

If your webservice requires this format a simple GET would be sufficient.
