Re: [PHP] Why doesn't working with array's ever stick in my thick head?
Hi Everyone,
I am taking another stab at this problem, complete with code and an
example...
Here is the issue:
I need to be able to display pounds and ounces of a given number of
pieces, the code I have does this just fine for a single route... But
what I can't seem to get through my head is how to do it for a
variable number of routes?
Here is the code I'm working with...
Weight calculator
Weight of a single piece:size="5" value="{$PieceWeight}">
HTML;
while ($c != $num) {
echo << Route Number:value="{$RouteNumber}"> Number of pieces: name="txtRoutePieces" value="{$RoutePieces}"size="5">Total
weight of route: {$weightExplode[0]}# {$explodeOunces} Ounceslabel>
HTML;
$c++;
}
echo "";
//DEBUG
dump_debug($RoutePieces);
dump_debug($RouteNumber);
dump_debug($_POST);
print_debug($explodeOunces);
dump_debug($weightExplode);
//END DEBUG
}else{
echo "";
echo "Number of routes:
";
echo "";
}
?>

I need help! My brain is going to die tonight without it :)

Then I think you want to use the mod operator: (I'm assuming .226 is the cost per ounce and 464 is the total number of ounces) $pounds = intval( .226 * 464 / 16 ); $ounces = ( .226 * 464 ) % 16; Roberto -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

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!
