    <p>I'm trying to send a few STRING variables from android to PHP as JSON. I accomplished this using one of the guides on the internet but unfortunately its not working and i'm unable to solve it using other similar questions on StackOverflow.</p> <p>Here's my android code :-</p> <pre><code>JSONObject jsonObject= new JSONObject(); JSONArray jsonArray=new JSONArray(); public class sendData extends AsyncTask&lt;String, String, Void&gt; { @Override protected Void doInBackground(String... params) { HttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost("http://bdp.site40.net/sendRegData.php"); try { HttpEntity httpEntity = new StringEntity(jsonArray.toString()); httpPost.setEntity(httpEntity); httpClient.execute(httpPost); } catch (IOException e) { } return null; } } public void onClickSubmitButton(View view) throws JSONException { jsonObject.put("name",name); jsonObject.put("blood",blood); jsonObject.put("cell",cell); jsonObject.put("email", email); jsonObject.put("address",address); jsonObject.put("country",country); jsonObject.put("state",state); jsonObject.put("city",city); jsonArray.put(jsonObject); new sendData().execute(); } </code></pre> <p>And here is my PHP code :-</p> <pre><code>&lt;?php $json = file_get_contents("php://input"); $data = json_decode($json); $name = $data[0]-&gt;name; $blood = $data[0]-&gt;blood; $cell = $data[0]-&gt;cell; $email = $data[0]-&gt;email; $address = $data[0]-&gt;address; $country = $data[0]-&gt;country; $state = $data[0]-&gt;state; $city = $data[0]-&gt;city; $con = mysql_connect("","","") or die(mysqli_connect_error()); $db = mysql_select_db("",$con) or die(mysqli_connect_error()); mysql_query("INSERT INTO Donors(Name,Blood,Mobile,E-Mail,Address,Country,State,City)VALUES('$name','$blood','$cell','$email','$address','$country','$state','$city')"); ?&gt; </code></pre> <p>After experimenting a little I have narrowed it down to the fact that the problem lies in which i SEND data to the PHP script AND/OR the way data is RECIEVED by the PHP script. Can anyone please look for the problem and correct it? Thank You!</p> <p>Points to Note:</p> <ol> <li>I have removed MySQL username,password,database name and host for privacy(obviously).</li> <li>All the 8 variables are in String format.</li> </ol>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
