Use Of Notifiers - How To

[swguy]

The first form is correct. Use zco_notifier for procedural cases.

Hi!

I'm trying to generate a file with shipping & order detail using the notifiers (NOTIFY_CHECKOUT_PROCESS_AFTER_SEND_ORDER_EMAIL).

The problem is that I need certain values be also included in the output file such as order id, product details and shipping weight.

I think when the trigger calls for my notifier, it is attached to order.php class only and $order->variables works just fine (except $order->order_id).

But I'd definitely like $shipping_weight (all cart weight + tare or large_tare) and $order_id be included.

How do I pass variables from shipping.php class?
And why wouldn't $order->order_id not working whereas $order->total_weight does?

Without looking in great detail, I suspect you will need to "global" the $shipping_weight variable in order to use it in your notifier class.

Also global the $insert_id if you want the number of the current order.

Thanks Dr. Byte!

'global'ling $insert_id worked. However, I still can't get the $shipping_weight to work, which I suspect that my observer is attached so well only to class order.php. Perhaps use a different notifier than NOTIFY_CHECKOUT_PROCESS_AFTER_SEND_ORDER_EMAIL?

Below is the code:

<?php
 class xml_generate extends base { 
   function xml_generate() {
     global $zco_notifier;
     $zco_notifier->attach($this, array('NOTIFY_CHECKOUT_PROCESS_AFTER_SEND_ORDER_EMAIL'));
   }
   function xml_config_switch() {
       if ( defined('GENERATE_XML') && (GENERATE_XML == 'false') ) {
          return false;
       } 
       return true;
   }
   function update(&$callingClass, $eventID) { 
       if (!$this->xml_config_switch()) return;
       global $order, $shipping_weight, $insert_id;
     //Begin USPS Domestic clause
     if (strpos($order->info['shipping_module_code'], 'usps') !== FALSE) {
     $xml_msg = "<DAZzle Layout='c:\endicia\dazzle7\Zebra Label.lyt' OutputFile='C:\endicia\dazzle7\xmlout\domestic" . strftime('&#37;Y%b%d-%H%M%S') . ".xml' Start='PRINTING' Test='YES' Prompt='NO' AutoClose='NO'>" . "\r\n";
  $xml_msg .= "<Package ID='1'>\r\n";
  if (strpos($order->info['shipping_method'], 'Parcel') !== FALSE) {$xml_msg .= "<MailClass>PARCELPOST</MailClass>\r\n";}
  if (strpos($order->info['shipping_method'], 'First') !== FALSE) {$xml_msg .= "<MailClass>FIRST</MailClass>\r\n";}
  if (strpos($order->info['shipping_method'], 'Priority') !== FALSE) {$xml_msg .= "<MailClass>PRIORITY</MailClass>\r\n";}
  if (strpos($order->info['shipping_method'], 'Express') !== FALSE) {$xml_msg .= "<MailClass>EXPRESS</MailClass>\r\n";}
  $xml_msg .= "<DateAdvance>0</DateAdvance>\r\n";
  $xml_msg .= "<PackageType>NONRECTPARCEL</PackageType>\r\n";
  $xml_msg .= "<Oversize>FALSE</Oversize>\r\n";
  $xml_msg .= "<WeightOz>" . ($order->total_weight * 16) . "</WeightOz>\r\n"; //works without handling charge
  $xml_msg .= "<WeightOz>" . ($shipping->shipping_weight * 16) . "</WeightOz>\r\n"; //returns 0
  $xml_msg .= "<WeightOz>" . ($shipping_weight * 16) . "</WeightOz>\r\n";  //returns 0
  $xml_msg .= "<Services>CertifiedMail='OFF' DeliveryConfirmation='OFF' ></Services>\r\n";
  $xml_msg .= "<Value>" . $order->info['total'] . "</Value>\r\n";
  $xml_msg .= "<Description>" . $order->products_ordered . "</Description>\r\n";
  $xml_msg .= "<ReferenceID>" . $insert_id . "</ReferenceID>\r\n";
  $xml_msg .= "<ToName>" . $order->delivery['firstname'] . " " . $order->delivery['lastname'] . " - " . $order->delivery['company'] . "</ToName>\r\n";
  $xml_msg .= "<ToAddress1>" . $order->delivery['street_address'] . "</ToAddress1>\r\n";
  $xml_msg .= "<ToCity>" . $order->delivery['city'] . "</ToCity>\r\n";
  $xml_msg .= "<ToState>" . $order->delivery['state'] . "</ToState>\r\n";
  $xml_msg .= "<ToPostalCode>" . $order->delivery['postcode'] . "</ToPostalCode>\r\n";
  $xml_msg .= "<ToEMail>" . $order->customer['email_address'] . "</ToEMail>\r\n";
  $xml_msg .= "</Package>\r\n</DAZzle>\r\n";
  $OutFile = "includes/xml/usps/domestic" . strftime('%Y%b%d-%H%M%S') . ".xml"; //Setting path n file name to USPS domestic
  } //End if USPS Domestic clause
  
  //Generate XML File
  $fp = fopen($OutFile, 'a');
  $fout = fwrite( $fp , $xml_msg );
  fclose($fp);
   }
 }
?>

Notice I'm trying 3 possible weight (in oz)?

$order->total_weight is likely your only option.

The $shipping_weight is only available in the shopping cart, which is empty after the order is placed.

Or you could write your own weight recalculator using the weight calculations in the calculate() function of the shopping_cart class.

Thanks Dr. Byte.

As I'm not much of a programmer, I'm just putting the static tare value matching what I've put on the configuration, unless there is a method of saving $weight in shopping_cart class to some other (global?) varible that does not get reset and passed onto my observer. Or should resetting of $weight commented out from shopping_cart class and be reset at the end of my observer?

Options:
a. extend the order database table to also store the total weight as calculated by shopping cart, and then write code to ensure that info gets stored appropriately
b. add a $_SESSION['shipping_weight'] variable before the shopping cart is reset, and then refer to that during your observer activities
c. alter the order-total class to store the weight in the shipping method details, and then extract that information during your export
d. recalculate the entire weight from scratch, rewriting much of the shopping-cart class

Try using this:

 $_SESSION['cart']->weight
