Function Calling

[Hobgoblin]

Hi,

I'm building a shopping cart program for a friend's small business. The cart works flawlessly, but there is a small part I am currently working on, where the user puts in their zip code, and a script (one I got off PHP Builder) looks up the postal zone, then the weight, and returns the shipping price.

Getting the zone works fine:

$tzip = $HTTP_POST_VARS['tzip'];
$zip = $tzip;

$var = GetZoneFromZip($zip);

echoing out $var brings up the appropriate postal zone.

The problem I'm having is the part where it looks up the zone and returns a price. Here's a smippet from that script:

function CalcPriMail($lb,$zone) { 

$lb = ceil($lb,0);

if ($lb == "1" && $zone == "1") { return "3.85"; }

The code I am using to get the return value from that script is below:

$lb = "$qttl";
$zone = "$var";

$shipping = CalcPriMail($lb,$zone);

$qttl is a variable obtained by a mySQL query retrieving the quantity of items in the shopping cart, divided by two. (since all their products weigh 8oz, nothing else is needed to calculate weight).

The error I get is:
Warning: Wrong parameter count for ceil() in /home/...... in line 13

So - anyone have any ideas what I'm doing wrong here? 🙂

You have to ensure that your variable $lb is set and $qttl is not empty before calling ceil:

if( empty($lb) ) { echo "bip!!"; }

Or may be you should not do

$lb = ceil($lb,0);

Rather

$newvar = ceil($lb,0)

But I guess it doesn't matter...

just use this line:

$lb = ceil($lb);
