enter <form method = "get" action = "register.php">
<label>Choose Department:</label><br>
<select name = "select" class= "textfields" id= "">
<option id = "">Choose department</option>
<?php
//connect to db
$connect = mysqli_connect('localhost', 'root', '', 'guu portal') or die ('cant you just connect to the database');
$query = "select * from departments";
$result = mysqli_query($connect,$query);
while($row = mysqli_fetch_array($result)){
$take = $row['id'] ;
?>
<option id = "<?php echo $take; ?>"><?php echo $row['departments']; ?></option>
<?php }
?>
