your button name attribute not set,
<button type="submit" name "add">add</button></td> make this:
<button type="submit" name="add">add</button></td> moreover not have form tags around form elements:
<form action="" method="post"> //set action php file //your table goes here </form> apart that, make sure name attributes identical post array keys.. example:
$username = ($_post['username']); won't value of following:
<input type="text" name="usernamr" placeholder="stud name" required/> because name username = usernamr..
