Checkout by Amazon Zen Cart Plug-in

[djdavedawson]

Amazon will not pass the attribute names = Amazons Checkout page and in the buyers control panel does not show them

Thank you for clarifying this.

Issue #4 - Attribute Names not showing on Amazon Checkout Page

Issue #5 - Special Characters breaks Order Push

The following is a workaround for both Issues 4 & 5

Open file -> checkout_by_amazon/button_generator.php

Find This:

$xmlBuilder->Element('Description', substr(zen_get_products_description($item[id],1), 0, MAX_DESC_LEN)); 

Replace with this:

$attributes_array = $cd->GetItemCustomXml($item);    
                            
              unset($attributes_result);             
                
                foreach($attributes_array as $row)
                  {                                  
                     if ($row['attributes']) {
                      
                         foreach($row['attributes'] as $k)
                         {
                               $attributes_result .= $k['options_name'] . ":  ";
                               $attributes_result .= $k['values_name'] . "  --  ";
                         }
                     }
                  } 
                              
            $xmlBuilder->Element('Description', $attributes_result . substr(preg_replace('/[^a-zA-Z0-9_ -]/s', '', strip_tags(zen_get_products_description($item[id],1))), 0, MAX_DESC_LEN)); 

This workaround simply puts the attribute names before the description at Amazons' Checkout Page when they are present.

This also strips all the html and special characters from the description when sent to Amazon.

This is a shock that someone had actually made progress to improve an aspect of this module. Do you know if its possible to include the attributes to show up on the buyer side Amazon seller central order screen? If this can be done, then I know of a few store owners who would make use of this module again as that is the biggest weakness to not use it.

While I might be the resident "repetitious know it all naysayer" I do agree with your thoughts.. Yep.. the attributes and the other issues (not to mention the lack of Amazon's support) were among the many reasons my client opted to not implement this payment module for now.. It's nice to see someone make forward progress with it.. Hoping one day that I will be able to fully implement it for my client..

If anyone is interested in Amazon checkout, I actually believe I've figured out the duplicate orders issue. The cause, I'm pretty sure, was that Amazon sent two statuses at one time - PROCESSING and UNSHIPPED - setting up race condition so sometimes orders got duplicated and sometimes they did not in amazonorder.php. What I did was set up semaphore to allow only one process to execute the critical code at a given time.

This works for us:

In amazonorder.php, at start of NewIOPNOrders function:

// *********** locking
// Get the lock
$lockfile = 'cache/amazon_order.lock';
$lock = fopen($lockfile, 'a');
$ret = flock($lock, LOCK_EX);
// *********** locking

Then at end of NewIOPNOrders:

// *********** locking
// Release the lock
$ret = flock($lock, LOCK_UN);
fclose($lock);
// *********** locking

One thing I would like to see fixed is for shipping option to be presented on Amazon with lowest cost choice. I haven't been able to figure that out, as Amazon seems to randomly pick default even if I sent them in order.

Just announced - a new Pay by Amazon developed by a UK firm and announced by amazon - I don't know anything more about it but at least it should work. http://go.amazonservices.com/UKCBASPZencart.html

The installation guide says the business address must be in UK, Germany or Luxemburg.

Well, that's a real irritation. You are right. I just let them know the rest of the world awaits.
