Using Amazon Web Services With PHP And SOAP (part 1) - Hooking Up (
Page 9 of 9 )
The ASINSearchRequest() method, combined with the AWS "heavy" data format,
makes it easy to build detailed product information pages that are similar to
the originals on Amazon.com. Consider the following revision to the example on
the previous page, which accepts an ASIN on the URL and returns a
neatly-formatted product information page:
<?php
// include class
include("nusoap.php");
// create a instance of the SOAP client object
$soapclient = new
soapclient("http://soap.amazon.com/schemas2/AmazonWebServices.wsdl",
true);
// uncomment the next line to see debug messages
// $soapclient->debug_flag = 1;
// create a proxy so that WSDL methods can be accessed directly
$proxy = $soapclient->getProxy();
// set up an array containing input parameters to be
// passed to the remote procedure
$params = array(
'asin' => sprintf("%010d", $_GET['asin']),
'tag' => 'melonfire-20',
'type' => 'heavy',
'devtag' => 'YOUR-TOKEN-HERE'
);
// invoke the method
$result = $proxy->ASINSearchRequest($params);
$items = $result['Details'];
// display the result
?>

Here's what it looks like:
Pretty cool, huh?
Now here's something for you
to think about. Remember how, a few pages back, I built a product catalog with
the BrowseNodeSearchRequest() method and linked each item in that catalog to the
actual product page on Amazon.com? Well, with the ASINSearchRequest() method,
you no longer need to link to Amazon.com for detailed product information - you
can generate it yourself! Simply alter the links in the product catalog to point
to the PHP script above, send the script the ASIN via the GET method, and you
can provide your visitors with detailed product information on your own
site.
I'll leave this last to you as an exercise. Give it a shot, and
come back next week for the second part of this article, when I'll be showing
you how to add search capabilities to your rapidly-evolving online store. See
you then!
