Question

我试图建立一个注册页面，用户可以在其中注册他们的姓名和其他详细信息。输入的详细信息可以上传到我的数据库。但是我无法将图像上传到数据库。

php代码

private static Cache<String, Integer> cache;

private static final String QUERY = "EXEC myQuery";

public static Integer getLanguageId(String language) {
    if (language == null) {
        return null;
    }
    Integer languageId = cache.get(language);
    if (languageId == null) {
        throw new Exception();
    }
    return languageId;
}

static void configureCache() {
    if (cache == null) {
        //CacheManager call database
        cache = CacheManager.getInstance()
                .createCache(QUERY, new RuleConfigurer.StringAndIntegerRowMapper());
    }
}

Java代码

RequestHandler.Java

 <?php


$hostname = "localhost";
//Define your database username here.
$username = "Droidparkz";
//Define your database password here.
$password = "***********";
//Define your database name here.
$dbname = "KEA";

$con = mysqli_connect($hostname,$username,$password,$dbname);

 $Image = $_POST['Image'];

 $id = 0;

 $res = mysqli_query($con,$sql);

 while($row = mysqli_fetch_array($res)){
 $id = $row['id'];
 }

 $path = "http://droidparkz.in/kea/profileimages/images/$id.png";

 $sql = "INSERT INTO User_details (IMAGE) VALUES ('$path')";

 if(mysqli_query($con,$sql)){
 file_put_contents($path,base64_decode($image));
 echo "Successfully Uploaded";
 }

 mysqli_close($con);

            else
                result.append("&");

            result.append(URLEncoder.encode(entry.getKey(), "UTF-8"));
            result.append("=");
            result.append(URLEncoder.encode(entry.getValue(), "UTF-8"));
        }

        return result.toString();
    }
}

通过参考一些在线教程和其他地方来完成代码。我不确定代码是否正确。如果您提供用于上传图像和文本的单个php代码，将为您提供很大的帮助。

使用php和android将图像上传到Mysql服务器
