Using Amazon Web Services With PHP And SOAP (part 2)
Add search features, shopping carts and wish lists to your AWS-backed online store.
| Rolling The Stones |
The first - and the simplest - type of search available in AWS is the keyword search, exposed via the KeywordSearchRequest() call. Here's a simple example of how it works:
// include class
// create a instance of the SOAP client object
$soapclient = new soapclient("http://soap.amazon.com/schemas2/AmazonWebServices.wsdl", true);
// set up an array containing input parameters to be
// passed to the remote procedure
$params = array(
'keyword' => 'rolling%20stones',
'page' => 1,
'mode' => 'books',
'tag' => 'melonfire-20',
'type' => 'lite',
'devtag' => 'YOUR-TOKEN-HERE'
// create a proxy so that WSDL methods can be accessed directly
$proxy = $soapclient->getProxy();
// invoke the method
$result = $proxy->KeywordSearchRequest($params);
// print the results
This is functionally similar to the scripts you've seen thus far; the primary difference lies in the call to a new function - KeywordSearchRequest() - and in the different arguments passed to it. The "keyword" argument passed to the function contains the words to be used as search keys in the specified Amazon catalog(s); note that this search term must be URL-encoded before being passed to the function.
Here's sample output from the script above:

Next, let's see how this can be integrated into the sample store I've been building.
