Loop problem

[Anon]

I am creating an order form that is populated by a .dat file. Each item appears in a separate table row with alternating red and gray background colors. Each row lists the item's name, price, and offers a dropdown to choose the quantity ordered.

I also want there to be a small input box that tells how much the person owes according to the quantity (1-10) they select from the dropdown. However, the boss wants the cost to change without having to press the submit button first (i.e., choose a number from the select box, and the input cost box automatically changes).

The problem I am having is that the price is generated in the for loop that pulls info from the dat file. Am I making any sense?

The code looks like this:

/* alternate bgcolor in a table */
function useColor(){
	/* remember the last color we used */
	static $ColorValue;

	/* choose the next color */
	if($ColorValue == "#990000"){
		$ColorValue = "#c0c0c0";
	}
	else{
		$ColorValue = "#990000";
	}
	return($ColorValue);
}

/* print table header */
	print "<center><a name=\"taste\" href=\"tasteoftexas.htm\"><img src=\"totop.gif\" width=\"411\" height=\"87\" border=\"0\"></a>\n";
	print "<table width=\"600\" cellpadding=\"3\" cellspacing=\"3\" border=\"0\">\n";

/* print taste of texas content */
$products = file("taste_of_texas.dat");
for ($i=0; $i<count($products); $i++){
	$products[$i] = stripslashes($products[$i]);
	$info = explode("|", $products[$i]);
		$title					= $info[0];
		$productname		= $info[1];
		$price					= $info[2];

	/* get color for this row */
	$RowColor = useColor();

	/* print out HTML for row and set bgcolor */
	print "<tr>\n";
	print "<td bgcolor=\"$RowColor\" width=\"425\"><font face=\"arial\" color=\"#ffffff\" size=\"-1\"><b>$title</b><br>\n";
	print "$productname</font></td>\n";
	print "<td bgcolor=\"$RowColor\" width=\"100\"><font face=\"arial\" color=\"#ffffff\" size=\"-1\"><b>Quantity:\n";

					/* set variable for quantity */
					$product_quantity = $productname . "quantity";

					print "<select name=\"$product_quantity\">\n";

					for($count=0; $count < 10; $count++)
					{
						print "<option value=\"$count\"";
							if ($product_quantity == '$count'){ print(" selected"); }
						print ">$count\n";
					}

					print "</select></b><br>\n";
	print "&nbsp;</font></td>\n";
	print "<td align=\"center\" bgcolor=\"$RowColor\" width=\"75\"><font face=\"arial\" color=\"#ffffff\" size=\"-1\"><b>\n";

					/* set variable for cost */
					$cost = $price * $quantity;
				print "$cost";
}

	/* print table footer */
	print "</table></center>\n";
	print "<p align=\"center\">\n";
	print "<font face=\"arial\" size=\"-1\"><a href=\"#order\">Place Order</a></font>\n";

Sorry if that was impossible to read... I've removed the font tags 🙂
