用于更新 android 中的 Base64 图像字符串的更新查询

Question

我有一个 php 页面有一个更新查询来更新图片

$email=$_POST['email'];
$name = $_POST['name'];
$phone= $_POST['mobile'];
$buffer = mysql_real_escape_string($_POST['image']);
$user_image = base64_decode($buffer);
require_once __DIR__ . '/db_connect.php';
$db = new DB_CONNECT();

$q="UPDATE  register SET  name ='$name',
    user_image ='$userimage',
    phone_number = '$phone' WHERE  register.email ='$email'";
if ($result) {
    $response["success"] = 1;
    $response["message"] = "Image successfully Updated.";
} else {
    $response["success"] = 0;
    $response["message"] = "Oops! An error occurred.";
    echo json_encode($response);
}

但它警告我

Warning: mysql_real_escape_string() [function.mysql-real-escape-string]: Access denied for user

这是我的异步任务 class，它将数据发送到 php 页面

    List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add(new BasicNameValuePair("email", email_id));
    params.add(new BasicNameValuePair("name", uname));
    params.add(new BasicNameValuePair("mobile", umobile));
    params.add(new BasicNameValuePair("image",setImageString));
    JSONObject json = jsonParser.makeHttpRequest(url_update_info,
            "POST", params);

Answer 1

调用前连接到数据库

$buffer = mysql_real_escape_string($_POST['image']);

像这样：

require_once __DIR__ . '/db_connect.php';
$db = new DB_CONNECT();

$email=$_POST['email'];
$name = $_POST['name'];
$phone= $_POST['mobile'];
$buffer = mysql_real_escape_string($_POST['image']);
$user_image = base64_decode($buffer);

basically, mysql_real_escape_string is done by mysql, you need a connection to mysql working

Answer 2

您可以像这样实现 mysql_real_escape 功能...

$email=$_POST['email']; 
$name = $_POST['name'];
$phone= $_POST['mobile'];
$buffer=$_POST['image'];
$user_image = base64_decode($buffer);

require_once __DIR__ . '/db_connect.php';
$db = new DB_CONNECT();
$query=sprintf("UPDATE register SET 
name='%s',user_image='%s',phone_number='%s' WHERE email='%s'", 
$name, mysql_real_escape_string($user_image), $phone, $email);
$result = mysql_query($query);
