html登录号如何显示用户名 HTML更改登录标签 登录后用户名

我想知道如何做到这一点后，我登录successfully.Just给我一些想法开始会做。？

这里是我的checklogin.php

session_start();

define("DB_HOST","localhost");

define("DB_NAME","user_database");

define("DB_USER","root");

define("DB_PASSWORD","");

mysql_connect(DB_HOST,DB_USER,DB_PASSWORD);

mysql_select_db(DB_NAME)

or die("Failed to connect to the database");

$myusername=$_POST["myusername"];

$mypassword=$_POST["mypassword"];

$myencryptedpassword=md5($mypassword);

$query="SELECT * FROM users WHERE username='$myusername' AND password='$myencryptedpassword'";

$result=mysql_query($query);

$count=mysql_num_rows($result);

if($count==1){

$_SESSION['is_logged']=true;

$_SESSION['username']=$myusername;

echo "Login Successful. Welcome ".$myusername;

sleep(2);

header("refresh:1;url=onlinestore.html");

}

else{

echo "Wrong Username or Password.Please try again. ";

sleep(2);

header("refresh:2;url=login.html");}

?>

代码这里是我的onlinestore.html

Login/Register;

代码这是我想改变身体的一部分。我希望它在登录成功后从登录/注册更改为用户名。

像raheel说的东西像一个会话或cookie –

请阅读了很多关于'SQL INJECTION'。还请阅读'PDO_MYSQL'而不是'mysql_ *' –
