将信息发送到服务器但信息在某处丢失

我在Android应用程序中调用此代码:

public static void sendAccelerationData(String userIDArg, String dateArg, String timeArg,
            String timeStamp, String lat, String longi, String alt)
    {
        //fileName = "AddAccelerationData.php";

        //Add data to be send.
        ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(6);
        nameValuePairs.add(new BasicNameValuePair("userID", userIDArg));
        nameValuePairs.add(new BasicNameValuePair("date",dateArg));
        nameValuePairs.add(new BasicNameValuePair("time",timeArg));
        //nameValuePairs.add(new BasicNameValuePair("timeStamp",timeStamp));

        nameValuePairs.add(new BasicNameValuePair("lat",lat));
        nameValuePairs.add(new BasicNameValuePair("longi",longi));
        nameValuePairs.add(new BasicNameValuePair("alt",alt));

        //this.sendData(nameValuePairs);
        try
        {
            TextLog.addLogStuff("SERV Trying to connect to Server");
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new      
            HttpPost("http://myserver.php");
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            HttpResponse response = httpclient.execute(httppost);
            Log.i("ServerConn", response.getStatusLine().toString());
            TextLog.addLogStuff("SERV PostData:  "  +response.getStatusLine().toString());
                //Could do something better with response.
        }
        catch(Exception e)
        {
            Log.e("log_tag", "Error:  "+e.toString());
            TextLog.addLogStuff("SERV Connection error:  " +e.toString());
        }  
    }

然后myserver.php的代码是:

  ?php


    //from the online tutorial:

    $usr = "bikemap";
      $pwd = "pedalhard";
      $db = "test";
      $host = "localhost";

      $cid = mysql_connect($host,$usr,$pwd);

      if (!$cid) { echo("ERROR: " . mysql_error() . "\n"); }

      $userID = $_POST['userID'];
      $date = $_POST['date'];
      $time = $_POST['time'];

      $lat = $_POST['lat'];
      $long = $_POST['longi'];
      $alt = $_POST['alt'];
       mysql_select_db("test");
      mysql_query("INSERT INTO gpsdata (userID, date, time, lat, longi, alt) VALUES ('$userID', '$date', '$time', '$lat','$longi','$alt') ") or die(mysql_error()); 

      /*$SQL = " INSERT INTO gpsdata ";
    $SQL = $SQL . " (userID, date, time, lat, longi, alt) VALUES ";
    $SQL = $SQL . " ('$userID', '$date', '$time', '$lat','$longi','$alt') ";
    $result = mysql_query("$SQL");

    if (!$result) {
        echo("ERROR: " . mysql_error() . "\n$SQL\n"); } */

    //echo ("New Link Added\n");



    mysql_close($cid); 
    ?>

不知何故,信息没有进入sql server。为了让方法开始,我一遍又一遍地传递6个字符串进行故障排除。这些都没有进入服务器。有什么想法吗?

编辑:

今天早上我尝试了更多故障排除。我将这些行插入到我的android代码中:

Log.i("ServerConn", response.getStatusLine().toString());
            TextLog.addLogStuff("SERV PostData:  "  +response.getStatusLine().toString());
            TextLog.addLogStuff("SERV rawData:  "  + nameValuePairs);

我从TextLog创建的文本文件中找到了这个:

11/11/2011 10:11:09:460 AM:  SERV userID:  Loren 
11/11/2011 10:11:09:464 AM:  SERV Trying to connect to Server 
11/11/2011 10:11:11:666 AM:  SERV PostData:  HTTP/1.1 200 OK 
11/11/2011 10:11:11:674 AM:  SERV rawData:  [userID=Loren, date=today, time=now,
    > lat=bit 1, longi=bit 2, alt=bit 3]

所以网页或服务器一定有问题,对吧?更多信息。

编辑v2:

我将其添加到php文件中:

$string = "User ID:  ";
$string = $string . $userID;
$string = $string . "Date:  " . $date;
$string = $string . "\n";


 $filename = 'test.txt';
 $fp = fopen($filename, "a");
 $write = fputs($fp, $string);
 fclose($fp);

这是文本文件的内容:

用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:
用户ID:日期:

问题1我是否使用正确的措辞写入文本文件?我今天早些时候回答了这个我正在使用正确的措辞。

问题2如果我使用的是正确的措词,那么从机器人到页面的数据会丢失吗?

谢谢大家!
