Adding information into the database - php

Question

private void AddGroupTasks(){
title1 = tTitle.getText().toString();
detail1 = tDetail.getText().toString();
ArrayList<NameValuePair> b = new ArrayList<NameValuePair>();
Tasks = new ArrayList<String>();
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost ("http://203.209.111.88/AddGroupTasks.php");
httppost.setEntity(new UrlEncodedFormEntity(b));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line=null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
So, When I click add,the information is supposed to be added to database. However, it gives a null value. By the way, I'm writing a to-do list app.
$Title = $_REQUEST['tTitle'];
$Detail = $_REQUEST['tDetail'];
$Group = $_REQUEST['spin'];
$DueDate = $_REQUEST['tDueDate'];
$Title = "'".$Title."'";
$Detail = "'".$Detail."'";
$Group = "'".$Group."'";
$DueDate = "'".$DueDate."'";
print $Title;
$database = "CloudList";
mysql_connect("localhost","root","1234");
mysql_select_db($database) or die("Unable to select database");
$q = "INSERT INTO message(group_name,message_title,message_details,message_due) VALUES($Group,$Title,$Detail,$DueDate)";
$result = mysql_query($q);
print $q;
mysql_close();
Here, This is my PHP Script.

Try this code, replace with your code and let me know what happen,
private void AddGroupTasks(){
title1 = tTitle.getText().toString();
detail1 = tDetail.getText().toString();
ArrayList<NameValuePair> b = new ArrayList<NameValuePair>();
Tasks = new ArrayList<String>();
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost ("http://203.209.111.88/AddGroupTasks.php");
b.add(new BasicNameValuePair("tTitle",
"anyTitle"));
b.add(new BasicNameValuePair("tDetail",
"anyDetail"));
b.add(new BasicNameValuePair("spin",
"AnythingaboutSpin"));
b.add(new BasicNameValuePair("tDueDate",
"anytDueDate"));
httppost.addHeader("Content-Type", "application/x-www-form-urlencoded");
httppost.setEntity(new UrlEncodedFormEntity(b, HTTP.UTF_8));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line=null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}

Try to set quotes in your Values section. It should look like:
$q = "INSERT INTO message(group_name,message_title,message_details,message_due) VALUES('$Group','$Title','$Detail','$DueDate')";
