Question

我刚刚在脚本中构建了一个php和mysql日志，该脚本可以转发到成员区域。我现在想要显示登录的成员名称，例如欢迎斯蒂芬。

最好的方法是什么？

这是我的代码

<?php

$host="localhost"; // Host name
$username="stephen2_phptest"; // Mysql username
$password="********"; // Mysql password
$db_name="stephen2_phptest"; // Database name
$tbl_name="registers"; // Table name

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];


// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);

$sql="SELECT * FROM registers WHERE email='$myusername' and password='$mypassword'";
$result=mysql_query($sql);

// Mysql_num_row is counting table row
$count=mysql_num_rows($result);

// If result matched $myusername and $mypassword, table row must be 1 row

if($count==1){

// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword");
header("location:members.php");
}
else {
echo "Wrong Username or Password";
}
?>

这是会员区的代码：

<?php

$host="localhost"; // Host name
$username="stephen2_phptest"; // Mysql username
$password="********"; // Mysql password
$db_name="stephen2_phptest"; // Database name
$tbl_name="registers"; // Table name

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
session_start();
if(!session_is_registered(myusername)){
header("location:index.php");

$myusername=$_POST['myusername'];
}
?>
<html>
<link rel="stylesheet" type="text/css" href="../php/css/styles.css">
<body>
    <div class="members-screen">
Login Successful</br>
Welcome [persons name to load here]<?php echo $_POST['myusername'] ?> <a href="../php/logout.php"> | Logout</a>
<div class="menu">
    <div class="menu-btn">
        <a href="">Home</a>
        </div>
        <div class="menu-btn">
            <a href="">Search</a>
            </div>
            <div class="menu-btn">
                <a href="">Messages</a>
                </div>
                <div class="menu-btn">
                    <a href="">Matches</a>
                    </div>
                    <div class="menu-btn">
                        <a href="">My Account</a>
                        </div>
    </div>
</div>
</body>
</html>

Answer 1

你要做的是： 1.加载用户名时将其保存到$ _SESSION变量中。就像$ _SESSION ['user'] = $ mysql_row ['user'] 2.每当你想要显示名字时放入$ _SESSION ['user']

Answer 2

在用户登录时将名称存储在会话中，并在需要显示时使用它。

session_start();

// Your login process

if($valid == true) {
   $_SESSION['logged_user'] = 'stephen'; // Fetch name from database
}

然后你需要在哪里展示：

session_start();
echo $_SESSION['logged_user'];

登录脚本加载用户名
