Question

我是网络开发和PHP的新手。我正在创建一个包含成员区域的网站，并希望显示欢迎“用户名”消息。在我的实际代码中，有一条欢迎消息显示用户的全名。有人可以帮我吗？下面我粘贴了我用于login.php和login-home.php（成员区域）的代码。谢谢

的login.php

<?PHP
require_once("./include/membersite_config.php");

if(isset($_POST['submitted']))
{
   if($fgmembersite->Login())
   {
        $fgmembersite->RedirectToURL("login-home.php");
   }
}

?>

Answer 1

简单的答案是你需要改变这行代码：

<div class='confirmation'>Welcome back <?= $fgmembersite->UserFullName(); ?>!</div>

这样$ fgmembersite-＆gt; UserFullName（）;成为保存用户名或返回用户名的函数的变量。现在它是一个返回用户全名的函数。

这可能会超出您目前的编程技巧。一个非常简单和可行的方法是在用户登录时将用户名存储为会话变量。然后您可以替换$ fgmembersite-＆gt; UserFullName（）;使用$ _SESSION [“用户名”]或您决定称之为的任何内容。

或者你可以定义你自己的函数来返回用户名，或者如果用户名由于某种原因不可用，还有一些其他的值（这稍微好些设计）。

将欢迎消息从全名更改为仅用户名（PHP）
