HTML Change login username after login

Before before log in

After enter image description here

I want to know how to do this after a successful login. Just let me know how to get started.

Here is my code for checklogin.php

<?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");} ?>

Here is my code for onlinestore.html

 <body> <li class='active' style='float:right;'><a href='registerform.html'><span id='register'>Login/Register</span></a></li>;

This is the part of the body that I want to change. I want it to change from Login / Register to username after a successful login.

You need a simple condition

 if($_SESSION['logged_in']){ echo $_SESSION['username']; }else{ echo 'Please login'; }

When your login condition becomes true, set some session data or cookie data, then use the condition to display content based on the session or cookie

You can do this with the if condition.

inside the html code, but before the label is defined.

 <?php if($_SESSION['is_logged']) echo "<label>$_SESSION['username']</label>"; else echo "<label>Please login</label>"; ?>
