Changing $_POST, while keeping its structure

[Enlightened]

I have tried a few suggestions, it seems its almost impossible to keep the post superglobals original structure. I dont know if this makes sense but here it goes.

Form Amount: 100.00 <-- $_POST['amount']

$total = $_POST['amount'];

$total + 2.00;

$_POST['amount'] = $total;

I'd like this to echo 102.00

Only displays what was entered (100.00)

Ive tried using (int) from a prior suggestion, It would only allow 2 digits to be entered, (11, or 30) opposed to 100.00

Im trying to keep the $_POST structure because im sending the post data as a whole through a class, Is this possible?

Any help is much appreciated.

If i did that would i be able to reference the original $_POST var

like $_POST['amount'] = $total; ?

Reason i ask is i have a class that requires the $_POST data

$order = new order($_POST);

So the new $_POST['amount'] would have to be changed from say, 100.00 to 102.00

As the $total var would.

Thanks for your reply

hi there
i think,
You would need to add the 2.00 extra charge before you send it thorugh POST.

I cant see another way to edit post unless you send it to another page add the 2.00 and re-submit the post variable

That would work to, Would i need to use js?

I tried doing name="amount" value="<?php echo $_POST['amount'] + 2.00; ?>"

but that didint work

Hello again,

ive built this bit of code for you, and yes the final out come produces POST with the 2.00 addedd to the total.

load the page up and see what i mean then edit it to your vars..

<?php
if (isset($_POST['Submit']))
{
$item_cost = $_POST['cost'];
$del_charge = 2.00;

$total = $item_cost + $del_charge;

echo "item costs\t". $item_cost. ".00<br>\n";
echo "delivery charge = \t" . $del_charge . ".00<br>";
echo "total =".$total . ".00<br>\n
<form method=\"post\" action=\"\">
  <input type=\"hidden\" name=\"total\" value=" . $total.">
  <input type=\"submit\" name=\"Search\" value=\"Submit\">
</form>";
exit();
}
if (isset($_REQUEST['Search'])){
	echo $_POST['total'];
	exit();
}
?>
<form name="form1" method="post" action="">
  <input type="text" name="cost">
  <input type="submit" name="Submit" value="Submit">
</form> 

Hope this helps you 🙂

Enlightened, you can do exactly as you first thought, and add two dollars directly to the post value.

<?php
// add two dollars and format the number
$_POST['amount'] = number_format($_POST['amount'] + 2.00, 2);
// now post amount is $2.00 more
echo $_POST['amount'];
?>

Hello again, I wanted to thank all that helped, I finally found the answer...

Using float opposed to int (as there is no decimals in an integer) would allow me

to get the result i needed. Once again thank you all

$_POST['x_amount'] = sprintf('%.2f', (float) $_POST['x_amount']+2);
