i'd created a login page, where user need to enter their username and password here, stored in
$username = $_POST["name"]; $password = $_POST["password"];
then after submit button being pressed, the username will show in welcome.php, which is the action for the submit button. From here, the user will have a link to another page with forms, here i need to display the username again. However it cant. How to make the variables pass across pages without using any database?
