I read these 2 articles to get me started with using Amazon Web Services:

I have a page with a Table of Contents linking to specific Browse Nodes that
would be of interest to our viewers.
I'd like to add a link to a results page with books published by Nolo Press.
To do this I'm passing the name "nolo" via the link.
Here is the code I have so far. Note, that it works perfectly when I only
want to see a list from a Browse Node.
CODE::
----------------------------
//get publisher information
$publisher = $_GET['publisher'];
if ($publisher == "nolo")
{
$publisher = "Nolo Press";
}
// if keyword is set, get those results
if (isset($keyword))
{
$catalogParams = array(
'keyword' => htmlentities($keyword),
'page' => $page,
'mode' => 'books',
'tag' => 'tag',
'sort' => '+pmrank',
'type' => 'lite',
'devtag'=> 'tag'
);
// invoke the method
$result = $proxy->KeywordSearchRequest($catalogParams);
$catalogItems = $result['Details'];
$catalogTotal = $result['TotalResults'];
}
else
{
// get items from the catalog
// sort order is default
$catalogParams = array(
'browse_node' => $node,
'page' => $page,
'mode' => 'books',
'tag' => 'tag',
'type' => 'heavy',
'devtag' => 'tag'
);
$catalogResult = $proxy->BrowseNodeSearchRequest($catalogParams);
$catalogTotal = $catalogResult['TotalResults'];
$catalogItems = $catalogResult['Details'];
}
if (isset($publisher))
{
//THE FOLLOWING LINE IS LINE 115
foreach ($catalogItems as $i)
{
if($i['Manufacturer'] == $publisher)
{
$catalogParams = array(
'browse_node' => $node,
'page' => $page,
'mode' => 'books',
'tag' => 'tag',
'type' => 'heavy',
'devtag' => 'tag'
);
$catalogResult = $proxy->BrowseNodeSearchRequest($catalogParams);
$catalogTotal = $catalogResult['TotalResults'];
$catalogItems = $catalogResult['Details'];
}
}
}
// format and display the results
?>
<!-- inner catalog table -->
<table border="0" cellspacing="5" cellpadding="0">
<?
// parse the $items[] array and extract the necessary information
// (image, price, title, author, item URL)
//THE FOLLOWING LINE IS LINE 209
foreach ($catalogItems as $i)
{
?>
<tr>
<td align="center" valign="top" rowspan="3">
<a href="book.php?asin=<? echo $i['Asin']; ?>">
<img border="0" src=<? echo $i['ImageUrlSmall']; ?>></a></td>
<td><b><a href="book.php?asin=<? echo $i['Asin']; ?>">
<? echo $i['ProductName']; ?></a></b> /
<? echo implode(", ", $i['Authors']); ?></td>
</tr>
<tr>
<td align="left" valign="top"><font size="-1">
<!--List Price: <? echo $i['ListPrice']; ?> / Amazon.com-->
Price: <? echo $i['OurPrice']; ?> / Used Price:
<? echo $i['UsedPrice'] ?>
</font></td>
</tr>
<tr>
<td colspan=2> </td>
</tr>
<?
}
?>
</table>
----------------------------------------------------------
END CODE
I get this error only if $publisher is set (these lines are marked above):
Warning: Invalid argument supplied for foreach()
in /home/www/palawport/amazon/sample7.php on line 115
Warning: Invalid argument supplied for foreach()
in /home/www/palawport/amazon/sample7.php on line 209
I did a little test and tried to see if catalogItems had any data. The
following code ONLY returned the Publisher ... nothing else.
print_r($catalogItems);
print "<p>";
print_r($publisher);
print "<p>";
print_r($keyword);
exit;
Suggestions are welcome :)
Thanks
Nicole
