[RESOLVED] Modifying $_POST input

[Enlightened]

Hello,

I was doing a lot of reading on the web, regarding modifying $_POST input and why its probably not a good idea. I couldnt quite understand why it shouldnt be done.

What i am trying to do is create an input, <input type="text" name="moo" value="<?php $total = $_POST['moo'] + 2.00; echo $total; ?>">

The idea is to add 2.00 to whatever they enter.

Is this truly a bad idea, Or am i probably looking over an easier solution?

Any help is much appreciated

There is nothing wrong with what you are doing.

The $_post value has already been returned to the server so there is NOTHING wrong with using it to decide what to display on the next page (including a form). Hell, that's the whole point of forms....
