Question

我正在尝试修改论坛的登录表单，以便在登录后，它会“欢迎使用用户名”。

这是signin.php内容的一大块 -

echo '<div id="username">Welcome, '+$USERNAME+'</div>';

然后，在index.php中，我想我会添加类似（伪代码）的行 -

#if defined(_STDEXT_BEGIN) && !(defined(_MSC_VER) && (_MSC_VER < 1400 || _MSC_VER >= 1600)) && !defined(_STLPORT_VERSION)
    stdext::unchecked_mismatch
#else
    std::mismatch
#endif
#if _MSC_VER >= 1600
    (stdext::make_unchecked_array_iterator(scan)+3, stdext::make_unchecked_array_iterator(scanEnd), stdext::make_unchecked_array_iterator(match)+3).first - stdext::make_unchecked_array_iterator(scan));
#else
    (scan+3, scanEnd, match+3).first - scan);
#endif

我试过玩$ _SESSION ['用户名']，但我在php中没用，所以任何指导都会非常有用，谢谢。

您可以使用会话

在您的登录脚本中：

Collecting mysql-python

...

session_start();

您要显示的位置：

}else{
    Users_LoggedIn($user, isset($_POST['remember_me']));

    $_SESSION['Username'] = $user['username'];

    header('Location: '.FORUM_URL); // redirects to index.php
    exit;
}

php - 将用户名保存为变量，然后在其他地方回显
