In the code that you posted the if statement should just go around the entire server behavior like this:
top of the if statement
<?php if ($eCart1->TotalColumn(TotalWeight) > 0 ){ ?>
the server behavior goes next
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
//WA eCart (Copyright 2007, WebAssist)
//WA eCart USPS Shipping - USPS
$Shipping_SuccessURL = "";
$Shipping_FailureURL = "shipping_failure.php";
$Shipping_Packaging = 0;
$Shipping_PackageArray = array();
$Shipping_PackageIndex = 0;
$Shipping_Counter = 0;
$Shipping_Parameters = array();
$Shipping_Parameters["UserID"] = "xxxxx";
$Shipping_Parameters["USPSServer"] = "http://production.shippingapis.com/shippingapi.dll";
$Shipping_Parameters["CarrierCode"] = "PRIORITY";
$Shipping_Parameters["DefaultIntl"] = "Airmail Parcel Post";
$Shipping_Parameters["ShipperZip"] = "92860";
$Shipping_Parameters["ShiptoZip"] = "92860";
$Shipping_Parameters["ShiptoCountry"] = "US";
while (($Shipping_Packaging == 1 && !$eCart1->EOF()) || ($Shipping_Packaging == 0 && $Shipping_Counter == 0)) {
if (WA_eCart_USPS_IsTrueValue("true")) {
$Shipping_PackageArray[] = array();
$Shipping_PackageIndex = sizeof($Shipping_PackageArray)-1;
$Shipping_PackageArray[$Shipping_PackageIndex]["eCart_Quantity"] = (($Shipping_Packaging == 1)?$eCart1->DisplayInfo("Quantity"):1);
$Shipping_PackageArray[$Shipping_PackageIndex]["IsPackage"] = "true";
$Shipping_PackageArray[$Shipping_PackageIndex]["Quantity"] = "1";
$Shipping_PackageArray[$Shipping_PackageIndex]["WeightUnits"] = "oz";
$Shipping_PackageArray[$Shipping_PackageIndex]["PackageWeight"] = "".$eCart1->DisplayInfo("TotalWeight") ."";
$Shipping_PackageArray[$Shipping_PackageIndex]["PackageType"] = "YOURPACKAGING";
$Shipping_PackageArray[$Shipping_PackageIndex]["PackageSize"] = "REGULAR";
$Shipping_PackageArray[$Shipping_PackageIndex]["PackageMachinable"] = "true";
$Shipping_PackageArray[$Shipping_PackageIndex]["IPackageType"] = "Package";
//Special Services
}
$Shipping_Counter++;
if ($Shipping_Packaging == 1) $eCart1->MoveNext();
}
if ($Shipping_Packaging == 1) $eCart1->MoveFirst();
$Shipping_Result = WA_eCart_USPS_GetRateQuote($eCart1, $Shipping_Parameters, $Shipping_PackageArray);
if ($Shipping_Result && $Shipping_SuccessURL != "")
$eCart1->redirStr = $Shipping_SuccessURL;
else if (!$Shipping_Result && $Shipping_FailureURL != "") {
Header("Location: " . $Shipping_FailureURL); exit;
}
}
else if (!isset($_SESSION["eCart1_USPS_Success"])) {
WA_eCart_USPS_SetSessionDefaults($eCart1);
}
?>
just after the server behavior you will put in the closing curly brace for the if
<?php } ?>
I also updated the cart that is referenced in the example to be your cart so you can put this code directly onto your page.
