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...

<?PHP
//Rural Route Weight Calculator by Jason Pruim 2008
	$c = "0";
	$num= "1";
	//$num = $_POST['txtNum'];
	$PieceWeight = $_POST['txtPieceWeight'];
	$RoutePieces = $_POST['txtRoutePieces'];
	$RouteNumber = $_POST['txtRoute'];


	//self submitting forms
	$self = $_SERVER['PHP_SELF'];
	$totalWeight = ($PieceWeight * $RoutePieces) /16;
	$weightExplode = explode('.', $totalWeight);
	$weightOunces = ((float)('.' . $weightExplode[0])) * 16;
	// Use stut's method... Seems cleaner
	$explodeOunces = ($totalWeight - intval($totalWeight)) * 16;
	if($_POST) {
		echo <<<HTML
		<div class="weightbox">
		<h1>Weight calculator</h1>
	<form method ='post' action='{$self}'>
		<p>Weight of a single piece:<input type="text" name="txtPieceWeight"  
size="5" value="{$PieceWeight}"></p>
		
HTML;

		while ($c != $num) {
			echo <<<HTML
			
			Route Number:<input type="text" name="txtRoute" size="5"  
value="{$RouteNumber}"> Number of pieces: <input type="text"  
name="txtRoutePieces" value="{$RoutePieces}"size="5"><label>Total  
weight of route: {$weightExplode[0]}# {$explodeOunces} Ounces</ 
label><BR>
HTML;
			
			
			
		
			$c++;
		
		}
			echo "<BR><input type='submit' value='Calculate'></form></div>";
	//DEBUG	
	dump_debug($RoutePieces);
	dump_debug($RouteNumber);
	dump_debug($_POST);
	print_debug($explodeOunces);
	dump_debug($weightExplode);
	//END DEBUG
	

	}else{
	echo "<form method='post' action='{$self}'>";
	echo "Number of routes: <input type='text' name='txtNum' size='2'><BR>
		<input type='submit' value='GO'>";
	echo "</form>";
	}
	


?>
