I want to create an android application that will connect to the CakePhp website and pass data between them. So I create a HTTP post request to pass my "email" and "password" to CakePHP loginsController for Login validation I use the android code shown in the below.

 List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
 nameValuePairs.add(new BasicNameValuePair("email", email));
 nameValuePairs.add(new BasicNameValuePair("password", password));
 try
{
  HttpClient httpclient = new DefaultHttpClient();
   HttpPost httppost = new HttpPost("http://10.0.2.2/Mebuddie/logins/login");

   httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8));
   HttpResponse response = httpclient.execute(httppost);
   HttpEntity entity = response.getEntity();
   InputStream is = entity.getContent();
   BufferedReader reader =
            new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
    StringBuilder sb = new StringBuilder();
    String line = "";
             while ((line = reader.readLine()) != null) 
                       {
                       sb.append(line + "n");
                       }
       is.close();
        Log.i("response", sb.toString());

       }
              catch (Exception e) 
                 {

                    e.printStackTrace();
                 }

If anybody can answer my question please help me. It's my request to all Cakephp and Android Experts. What can i write on the LoginsController to handle this request?

I write some code in login() function under Logins_controller in my cakephp shown below,

         public function login() {

            pr($_POST);

        if ($this->data && 
                isset($this->data['email']) && isset($this->data['password']))
        {
            $arrUser  = $this->Login->find('all',array(
                    'conditions'=>array(
                        'email'=> $this->data['username'],
                        'password' => $this->Auth->password($this->data['password']),
                    )
                )
            );


             if (count($arrUser) > 0)
            {
                $arrReturn['status'] = 'SUCCESS';
                $arrReturn['data'] =
                      array( 'loginSuccess' => 1,'id' => $arrLogin[0]['Login']['id'] );
                 //logged in
            }
            else {
                $arrReturn['status'] = 'NOTLOGGEDIN';
                $arrReturn['data'] = array( 'loginSuccess' => 0 );
            }
                echo json_encode($arrReturn);
        }

The pr($_POST); function send back the content of the post requst to the android aplication . when i print response in the logcat in the eclipse ide it shows,

                  <pre>Array
             (
                 [email] => imransyd.ahmed@gmail.com
                 [password] => Cpa@2011
             ) 
                    </pre>

Along with All html content in the login form .

**My Question is,

       1.How can i get back  only the email & password without the  html content.

       2. how to return the values in the $arrReturn from the cakephp to my android          application 
please give me an example code for return data from cakephp to android**

$this->request->data['email'] and $this->request->data['password'] should contain your data.

If you are unsure of how the data is posted, send back the content of the $_POST with: pr($this->request->data) inside your login action.

E.g. your login action can look like this:

<?php
public function login()
{
    if ($this->request->is('post'))
    {
        $this->Auth->fields = array(
            'username' => 'email',
            'password' => 'password'
        );
        if ($this->Auth->login($this->request->data))
        {
            //logged in
        }
    }
}

for CakePHP version 1.3 replace $this->request->data with $this->data and replace is('post') with isPost().

Your questions:

  1. How can i get back only the email & password without the html content.
echo $this->data['email'];
echo $this->data['password']
exit;

or use echo json_encode($this->data); for a more structured response

  1. how to return the values in the $arrReturn from the cakephp to my android application please give me an example code for return data from cakephp to android

Use json_encode($arrReturn);. See How to parse JSON in Android for an example how to handle json data.

  • To only return your username and password, I would suggest using json data, e.g. `echo json_encode($this->data);` then `exit;` to skip all html in layout and view – Yoggi Jan 17 '13 at 08:38
