Are you sure you need to use sessions? What does input.php do with the data, can you not just pass it straight on to output.php?

Are you sure you don't mean a multiple select box?

If it's just a check box you do something like this:

   <?php
   session_start();
   
   $_SESSION['checkbox_name'] = $_POST['checkbox_name'];

That will store an empty value if it's not checked and the string "on" if it is checked, unless you give the "value" attribute of the checkbox element a value, then that string will show up if checked.

For a multiple select do something like this:

The code for the form:

   
    <select multiple name="multipleSelect[]">
     <option value="option one">option one</option>
     <option value="option two">option two</option>
    </select> 

The code that handles the form:

   <?php
   session_start();
   
     $_SESSION['multiple_select'] = $_POST['multipleSelect'];

This is assuming you're using the "post" method in your forms. The multiple select form element will be posted as an array, so you can just store the array in a session variable.

<?php

   session_start();

   

     $multiple_select = $_SESSION['multiple_select'];
