Hi there,

In your <form> tag, you need to put an action and a method. The action will tell the page where to go when you hit a submit button (i.e., process.php or load_value.php, anything like that, wherever you want it to go) and the method will determine whether the values in your form are submitted via POST or GET.

So, this should do the trick and transfer any values with a 'name' associated to them to your 'action' page:

<form action="wherever_you_want.php" method="post">

//all of your code

<input type="submit" value="submit">
</form>

OK, but just for your reference, I don't believe that you can have a form within a form. You need to have all of your ducks in a row, so to speak, before you plan out your form and submit actions. So here's what I think would be the easiest thing to do in your PHP form ---

Have a single form and submit button and link that to a form validation to determine if the user is a teacher or a student, then direct the user to the appropriate page via an if/else conditional using different header("Location:ex.teacher.php") rules. Does this make sense?

What I would do is have a boolean column with my users something like 'isTeacher' or 'isStudent', then search for that parameter in my conditional. So, something like:

<?php
$user_rollno = $_POST['user_rollno'];
//Note --- ALWAYS filter input, so if you're using a mysqli database, you would have $user_rollno = mysqli_real_escape_string($db_connection, $_POST['user_rollno'])  OR use a PHP sanitize filter, which you can find on php.net

Then find them in your array of users, I'll assume a MySQL database using procedural PHP:

$query = "SELECT * FROM users WHERE user_rollno = $user_rollno;";
$result = mysqli_query($db_connection, $query);
$row = mysqli_fetch_array($result);
$isTeacher = $row['isTeacher'];

if($isTeacher) {
header("Location:teacher_page.php");
} else {
header("Location:student_page.php");
}

?>

And you can set any queries in the URL to direct them to specific pages or whatnot.

Does this help?
