android로 SQL 행을 업데이트하려고 시도했습니다.

Question

SQL 데이터베이스에서 일부 행을 업데이트하려고했습니다. php 함수는 잘 작동하지만 안드로이드 코드에 적용하면 아무 것도 바뀌지 않습니다. 내 응용 프로그램을 실행할 때 내 응용 프로그램은 "Update Successfull"이라고 말하지만 SQL 데이터베이스에서는 항상 동일합니다.

누구든지 나를 도와 주거나 해결책을 찾도록 도와 줄 수 있습니까?

id | username | password | email | name 

PHP 함수의 코드 :

<?php 
if(isset($_POST['update'])) 
{ 
$dbhost = 'localhost'; 
$dbuser = 'dbuser'; 
$dbpass = 'dbpassword'; 
$conn = mysql_connect($dbhost, $dbuser, $dbpass); 
if(! $conn) 
{ 
    die('Could not connect: ' . mysql_error()); 
} 

$username = $_POST['username']; 
$name = $_POST['name']; 

$sql = "UPDATE tbl_user SET name = '$name' WHERE username = '$username'"; 

mysql_select_db('my_table'); 
$retval = mysql_query($sql, $conn); 
if(! $retval) 
{ 
    die('Could not update data: ' . mysql_error()); 
} 
echo "Updated data successfully\n"; 
mysql_close($conn); 
} 
else 
{ 
?>

이 그것을 작동하는 솔루션입니다 .... 그것은 미래의 누군가에 도움이 될 수 있습니다 희망

String nameperson = nome.getText().toString();
