Telling Differece Between A Real Number Or An Error String.

[websmoken]

I'm working on a UPS rates program for my shopping cart.  I come back with an actual shipping amount like 23.55 or an error.  I need to set a variable like $_SESSION["UPS_Error"] if I do.  The errors I've encountered are:

 

error (This is what I get if UPS were busy or offline)

Missing ServiceLevelCode

Missing ShipperPostalCode

Missing ConsigneePostalCode

The maximum per package weight for the selected service from the selected country is 150 pounds.

I've tried the "gettype() " and tried "function check_int" It was probably something I did wrong but couldn't get thoses to work.    Maybe one of ya'll expert coders could lead me in the right direction.

Thanks,

You could replace this...

 

 

    $quote = $rate->getQuote();
			echo $quote;
?>

 

With this...

 

	$quote = $rate->getQuote();

if ( abs ( $quote ) == 0 )
{
	// not a valid dollar amount, so we have an error
	$_SESSION['UPS_Error'] = $quote;
}
else
{
	// got a valid return dollar amount, so show it!
	echo $quote;
}
?>
