editing POST data

Enlightened

Hello, I would like to edit some POST data before running it through some classes,

For instance, I have $_POST['amount'], I would like to add 2.00 to it. If i do something like:

$total = $_POST['amount'] + 2.00;

echo "$total";

It works, but with this class, im passing all the $_POST data through, Which means it would ignore the total var. Is there a way to "add" to the post?

Or is there an easier way to edit it within the form on submit?

You already get the result you want so within your forum why don't you first use the $total = $_POST['amount'] + 2.00; and then make $total a hidden value like the below:

echo "<input type=\"hidden\" value= \"$total\" name=\"total\">";

Now when you submit your form you will pass the $_POST['amount'] with its newly adjusted value and then just access the total variable.

$_POST['amount'] += 2;

It's not like the array is read-only 🙂

Or make a new array index to store the new POST data:
$POST['total'] = $POST['amount'] + 2;

Even better still, rewrite those classes so that they aren't tied irrevocably to getting their data from $POST but instead can get them from any array passed to it. Then you could pass the $POST array as-is, or take the opportunity to build a new array with whatever values are appropriate and pass that.
