我为我的移动应用程序创建了一个登录系统，但按下按钮的那一刻没有任何反应。当我查看网络监视器时，它正在连接，所以我想知道出了什么问题。

我错过了什么吗？

.mxml 文件：

您正在使用mysqli连接到数据库，但调用过时的 mysql_## 函数来执行查询。

而是更新您的代码

$query = "SELECT * FROM account WHERE email = '$username' AND password = '$password'";
$result = $mysqli->query($query);
if(!$result->num_rows)
// No Results Found
else
// Results found
