use of POST with multiple variables

hi! I've been working for a while with the ethernet shield but there is a part that I can't make it work. I try to connect with a website using the POST method, but it doesn't seem to work with more than one variable. Here is the code:

void detectSensors(){
  //Here we will assign the name for each sensor
  String sensorname= "sensor1=office";
  String sensorname2= "sensor2=showroom";
  String toarray= sensorname2+"&"+sensorname;
  //CREATE A TABLE FOR THIS ARDUINO WITH THE NAME OF ARDUINOTABLE
  if (client.connect(myserver, 80)) {
    Serial.println("Putting sensors..");
    client.println("POST /my/sensors.php HTTP/1.1");
    client.println("User-Agent: arduino-ethernet");
    client.println("Host: www.webpage.com");
    client.println("Connection: close");
    client.println("Content-Type: application/x-www-form-urlencoded;");
    client.print("Content-Length: ");
    client.println(toarray.length());
    client.println();
    Serial.println(toarray);
    client.stop();
    Serial.println("Yes!! sensors put");  
    } 
  else {
    Serial.println("connection failed, sensors not put...");
    Serial.println();
  }
}

If I do with only one variable I find no problem, and the website reads the POST perfectly, when I put two, I can connect to the website but there is no readable POST...Any suggestion?

The code you posted POSTS no data. Why not?

    Serial.println(toarray);

Really looks to me like that should be client.println.

Of course, POSTing "sensor1=office&sensor2=showroom" makes no sense to me. YMMV.
