Remembering session inputs
I’m starting to build an order form that has a five step process. Size, color, quantity, etc. Everything will be added up on the fifth step. I am new to sessions, but I think I can get that part to work, the problem that I can see is this: What if a user wants to change something on step one when they’re finished? It’s probably simple. I’m thinking that it will be along the lines of…
<?php session_start();
if $_SESSION[‘choosesize’] is there, then show the size
else, blank selection
?>
<select name=”choosesize”>
<option value=”small”>small</option>
<option value=”medium”>medium</option>
</select>
As you can see I don’t know what the code would be. But this idea should work right? Linking 5 php pages together with sessions to be totaled on the final page?

echo "<option value='$val'$select>$val</option>n";
