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:

''.preg_replace(array('/  /', '/ /'), array('  ', '   '), '
    [TotalResults] => 163
    [Details] => Array
            [0] => Array
                    [Url] => http://www.amazon.com/exec/obidos/redirect?tag=melonfire-20%26creative=YOUR-TOKEN-HERE%26camp=2025%26link_code=sp1%26path=ASIN/1556523734
                    [Asin] => 1556523734
                    [ProductName] => Nankering With the Rolling Stones
                    [Catalog] => Book
                    [Authors] => Array
                            [0] => James Phelge

                    [ReleaseDate] => April, 2000

                    [ImageUrlLarge] => http://images.amazon.com/images/P/1556523734.01.LZZZZZZZ.jpg
                    [ListPrice] => $16.95
                    [OurPrice] => $11.87
                    [UsedPrice] => $10.95

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

How to do Everything with PHP & MySQL
