Subject: RE: [PHP] Looping Addition
Let me explain this as best I can. The user enters how many numbers he
wants
to add. This form goes to another page. This page loops a form field
and
it's name is num and after num is the number
One more question... If I then wanted to do this for the other operations
(such as multiplication, division, etc), how would I do that?
Assuming you've figured out how to do an array...
You'll have to loop through the values like in the code that others posted.
foreach($_POST['number'] as
:24 AM

So would I just put this?
foreach(%_POST['number'] as $num)
{
$output *= $num;

echo $output;
That's for multiplication.
Yes. Wouldn't it have been quicker for you to try it than to ask?
BTW make sure that none of $num is zero.

Continuing this even more...how would I use this same method only to
subtract?

You simply need the absolute value of the difference. So taking Stephen's
example below..
$total = 0;
foreach( $_POST['nums'] as $number )
{
$total -= $number;// if users inputs 5 as first value result
equals -5
$total = abs($total
But then, if the user entered 5 - 6, it should be -1 but it'd return
positive one... Is there another way?
Come on, man... this is addition and subtraction. You can't figure it out?

No, I wasn't going to ask that. But thanks for the info. :P

What type is $_POST['vars']? I think that it is a string...you might
have to convert it to an integer...
if( is_numeric( $_POST['vars'] ) )
{
$vars = (int)$_POST['vars'];
}
else
{
echo Error: \$_POST['vars'] is not an integer.;
}

there are no more to add...
If you mean that $_POST['vars'] is an array of numbers:
$total = 0;
foreach(

Let me explain this as best I can. The user enters how many numbers he
wants
to add. This form goes to another page. This page loops a form field
and
it's name is num and after num is the number it is currently on.
Here's
the code:
form name=add method=post action=?php
18 matches
