Question

这是我的登录页面。我从这里得到什么代码或查询，并添加到我想显示用户名的位置，以显示用户的全名？

<?php
define('DB_HOST', 'localhost');
define('DB_NAME', 'university portal');
define('DB_USER','root');
define('DB_PASSWORD','password007');

$con=mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or die("Failed to connect to MySQL: " . mysql_error());
$db=mysql_select_db(DB_NAME,$con) or die("Failed to connect to MySQL: " . mysql_error());
/*
$ID = $_POST['user'];
$Password = $_POST['pass'];
*/
function SignIn()
{
session_start();   //starting the session for user profile page
if(!empty($_POST['UserName']))   //checking the 'user' name which is from Sign-In.html, is it empty or have some text
{
    $query = mysql_query("SELECT Username, Password, voting_status FROM voters where Username = '$_POST[UserName]' AND Password = '$_POST[password]'") or die(mysql_error());
    $row = mysql_fetch_array($query) or die(mysql_error());
    if(!empty($row['Username']) AND !empty($row['Password']))
    {

        $_SESSION['Username'] = $row['Password'];
        $_SESSION['Voting Status'] = $row['voting_status'];
        header("location:Voters Account.php");

    }
    else{
        echo "username or password is incorrect";
    }
}
}
if(isset($_POST['submit']))
{
    SignIn();
}
          ?>

这是我想要显示用户全名的地方，所以请真的需要帮助，谢谢。

Answer 1

在[用户名]行中打印用户名：

echo $row['Username'];

Answer 2

首先登录代码更改

 $_SESSION['Username'] = $row['Password'];

到

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

如果要显示用户名的页面是登录后的页面，只需启动会话并显示如下用户名

echo $_SESSION['Username'];

希望有所帮助

如何从数据库中获取用户名，并在用户登录时将其显示给用户？
