好的，我需要帮助。作为一名新程序员，我正在设计一个登录和注册活动。我有数据库问题。它不是存储输入数据库不存储信息
注册请求
import com.android.volley.Response;
import com.android.volley.toolbox.StringRequest;
import java.util.HashMap;
import java.util.Map;
public class RegisterRequest extends StringRequest {
private static String REGISTER_REQUEST_URL = "http://localhost/Register.php";
private Map<String, String> params;
public RegisterRequest(String name, String password, String email, String gender, Response.Listener<String> listener){
super(Method.POST, REGISTER_REQUEST_URL,listener,null);
params = new HashMap<>();
params.put("name", name);
params.put("password", password);
params.put("email", email);
params.put("gender", gender);
}
@Override
public Map<String,String> getParams(){
return params;
}
}

注册PHP来存储数据库
信息$con = mysql_connect("localhost", "root", "batman", "database");
$username=$_POST["username"];
$password=$_POST["password"];
$email=$_POST["email"];
$gender=$_POST["gender"];
$statement = mysqli_prepare($con, "INSERT INTO register (username, password, email,gender) VALUES (?, ?, ?, ?)");
mysqli_stmt_bind_param($statement, "siss", $username, $password, $email, $gender);
mysqli_stmt_execute($statement);
$response = array();
$response = ["success"] = true;
echo json_encode($response);
请帮我查一下。
