替换
start_session();
借-
它的会话\u开始()不是start\u会话()
也可以在index.php中使用
<?
include "functions.php";
if(!isset($_SESSION))
{
session_start();
}
if($_SESSION['ses_username'] == '')
{
session_destroy();
}
?>
你在用什么代码
start_session();
session_destroy();
start_session();
拆下所有这些部件,并将其更换为
session_start();
if($_SESSION['ses_username'] == "")
{
session_destroy();
}
不工作意味着什么?什么不起作用?您是否收到任何错误?您必须在页面顶部使用session\u start()
,并且只能使用一次。您为什么要多次使用它?/我登录时总是显示此警报代码。?>警报(“用户名/密码tidak terdaftar”);location.href=“index.php”;替换start_session()时仍然不想工作;使用session_start();在register globals和会话cookies中是否有php.ini配置的链接?我已经将您的代码放入了我的代码中,但仍然无法登录。。。安全检查总是在说:您的用户名和密码错误时激活。我已经仔细检查了用户名和密码是否正确。我已经将您的代码放入我的代码中,但仍然无法登录。。。安全检查总是在说:您的用户名和密码错误时激活。我仔细检查了用户名和密码是否正确。
session_start();
if($_SESSION['ses_username'] == "")
{
session_destroy();
}
