Hi Everyone,
SO it's friday, I'm tired, and I can't seem to think straight... I am
attempting to do some very basic math with some arrays... Here's
the pseudo
code that I'm working with:
NumberOfPieces * PieceWeight = TotalWeight
explode total weight to get tenth's of pounds, then divide tenth's of
pounds by 16 to grab ounces.
Display TotalWeight # Exploded Ounces.
Which I have working just fine for a single set of boxes...
My problem is I want to be able to automatically add say 50 boxes
in a form
to process the weight of each route...
So what I need to do is probably use some kind of a counter to loop
through
my $RoutePieces array and multiply by the $PieceWeight?
$PieceWeight is a
static number.
Now let me show you some abbreviated code to try and explain what
I'm using
right now:
<?PHP
$i= "0";
$num= "2";
$PieceWeight = $_POST['txtPieceWeight'];
$RoutePieces[] = $_POST['txtRoutePieces'];
$RouteNumber[] = $_POST['txtRoute'];
$totalWeight = $PieceWeight * $RoutePieces/16;
$weightExplode = explode('.', $totalWeight);
//$weightOunces = ((float)('.' . $weightExplode[1])) * 16;
// Use stut's method... Seems cleaner
$explodeOunces = ($totalWeight - intval($totalWeight)) * 16;
while($i <= $num){
echo <<<HTML
<p>
Route Number:<input type="text" name="txtRoute[$i]" size="4"
value
="{$RouteNumber[$i]}"> Number of pieces: <input type="text"
name="txtRoutePieces[$i]" size="4"
value="{$RoutePieces[$i]}"><label>Total
weight of route: {$weightExplode[0]} # {$explodeOunces} Ounces</
label>
</p>
HTML;
$i++;
echo $i;
}
?>
the $_POST array has the proper values stored properly... I just
can't seem
to figure out how to work with the values... Any ideas? Or slaps on
the back
of the head to wake me up a little? :)
I need help :P

Rather than a counter, you could use foreach:
foreach ( $RoutePieces as $key => $value )
{
$blah = $value * $PieceWeight;
}
Make sense?
The idea make sense, and I think it will work. But I'm getting this
error:
[Fri May 9 13:19:33 2008] [error] PHP Fatal error: Unsupported
operand types in /Volumes/RAIDer/webserver/Documents/dev/weightcalc/
index.php on line 22
foreach ($RoutePieces as $key => $value){
$testWeight = $value * $PieceWeight; <-------Line 22
}
Some quick trying tells me that the problem is my "*" I don't remember
having this problem before. Is there another character I should use to
multiply with? :)
Thanks for looking!
