我是Android新手,我正在開發一個PHP和MySQL應用程序。我試圖從我的設備發送一些數據到PHP腳本,並將數據添加到我的數據庫,但添加到數據庫的數據爲空。我不使用模擬器,只使用Android設備。這是我的PHP和Java代碼:Android設備發送空數據到PHP
$dbHost = "localhost";
$dbName = "emergency_db";
$dbUser = "root";
$dbPassword = "";
$connect = mysql_connect($dbHost, $dbUser, $dbPassword) or die ("Connection error"); // connects to database
mysql_select_db($dbName) or die ("Database selection error"); // selects the database
$username=$_POST['username'];
$password=$_POST['password'];
$name=$_POST['name'];
$email=$_POST['email'];
mysql_query("INSERT INTO USERS(Username, Password, Name, Email)VALUES('$username', '$password', '$name' , '$email')");
mysql_close($connect);
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://localhost/register.php");
List<NameValuePair> params = new ArrayList<NameValuePair>(4);
params.add(new BasicNameValuePair("username", username));
params.add(new BasicNameValuePair("name", name));
params.add(new BasicNameValuePair("email", email));
params.add(new BasicNameValuePair("password", password));
httppost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
你測試你要發送的空值的數據? – kabuto178 2013-05-13 18:49:59
我已經測試了手機中的數據,它們不是空的。 – 2013-05-13 19:02:43
我是新來的PHP,我想你需要打開Db連接 – 2013-05-13 19:22:33
