Question

This is so simple, yet I cannot get my head into the logic.

Have a simple online form. Want to be able to adjust a variable after submitting.

If anyone can shed light on this one, would be really super appreciative!

$chocolatebar = $HTTP_POST_VARS['chocolatebar'];

if $chocolatebar = "a"  then we want to change the value to "snickers";

if $chocolatebar = "b"  then we want to change the value to "mars";

if $chocolatebar = "c"  then we want to change the value to "cherry ripe"; 

Answer 1

$chocolatebar = isset($_POST['chocolatebar']) ? $_POST['chocolatebar'] : '';
if ($chocolatebar == "a")  $chocolatebar = "snickers";
elseif ($chocolatebar == "b")  $chocolatebar = "mars";
elseif ($chocolatebar == "c")  $chocolatebar = "cherry ripe";
