Question

I have a problem with this code:

    <?php   echo "<meta http-equiv='refresh' content='3;search_enroll.php?&id='.$id />"; ?>

I’m using this code to pass a value from this page to this page with $id and it is not empty I echoed $id and it holds the value. And this is the code on the receiving end:

   <?php
            if (isset($_POST['SearchS'])){
                $id = $_POST['searchstudent'];

            }else if(!empty($_GET['id'])){
                $id = $_GET['id'];
            }
            else if(!empty($_GET['student_id'])){
                $id = $_GET['student_id'];
            }

            else {
                $id= $_REQUEST['student_id']; <--- this is line 37
            }
            ?>

currently having this error note and I expect the 2nd else statement should retrieve the code.

Notice: Undefined index: student_id in C:\xampp\htdocs\Thesis\search_enroll.php on line 37

Do your string escaping right or don’t do it at all:

<?php
    echo "<meta http-equiv='refresh'
                content='3;search_enroll.php?id=".$id."' />"; ?>
