当我运行代码时,它只给我一个空白页面,并且不会从login.php继续
我做过echo $ test = $ stmt-&gt; affected_rows;这显示为-1我不熟悉PHP,并不真正了解它出错的地方。

if($stmt->execute()){
//Gets the results and assigns it to $result
$result = $stmt->get_result();
//runs a while loop so that the role can be pulled out and assigned to $role for the switch
while($row = $result->fetch_assoc()){
$role = $row['role'];
}
// If result matched $myuser
最后修好了!感谢您的帮助,让您朝着正确的方向前进。
