Hello, trying to get this script to run and getting error messages. Can someone else give it a try? I'm sure it is not that difficult for you seasoned pros...yes I'm trying to butter you up. ;-)

Here's the code:

<?php

// AOL Video Search REST API
// Basic Video Search application using PHP 5
// Using SimpleXML library for XML parsing, and CURL for server to server requests
// Author: Moninder Jheeta
// August 26, 2006

{

$appid = "1x1jhj64466mi12ia";

if (isset($_POST['searchBox'])) {

// get the query from the searchBox variable

$query = $_POST['searchBox'];

// urlencode the query, and assemble the REST request

$apiRequest = "http://beta.searchvideo.com/apiv3?appid=$appid&method=truveo.videos.getVideos&query=" .
urlencode($query) .
"&start=0&results=25&showAdult=1";

// open a curl session to process the REST request
// use the option CURLOPT_HEADER to make sure that http headers are retrieved along with the REST response xml
// use the option CURLOPT_RETURNTRANSFER to have the REST response put into a string variable for your use

$curlSession = curl_init($apiRequest);
curl_setopt($curlSession, CURLOPT_HEADER, true);
curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, true);
$xmlResponse = curl_exec($curlSession);
curl_close($curlSession);

// parse the HTTP status code out of the status header to make sure that the request returned correctly

$httpStatusHeader = array();
preg_match('/\d\d\d/', $xmlResponse, $httpStatusHeader);
$httpStatusCode = $httpStatusHeader[0];

// since the $xmlResponse variable includes the http headers as well as the actual xml response, get
// the xml response by taking the part of $xmlResponse starting from <?xml

$xml = strstr($xmlResponse, '<?xml');

// using the SimpleXML library, available in PHP 5, load the xml string into an object
// for more info on SimpleXML, see http://php.net/manual/en/ref.simplexml.php

$xmlObject = simplexml_load_string($xml);

// if the HTTP status code is 403, 503, or 400, then throw an exception
// which includes the error message given by the REST API

if ($httpStatusCode == 400 || $httpStatusCode == 403 || $httpStatusCode == 503 ) {
$Error = $xmlObject->Error;
throw new Exception($Error);
}

// get the VideoSet, VideoSet title, and number of videos from the xml response, and pass to the
// createThumbnailTable function along with the dimensions desired for the table.

$VideoSet = $xmlObject->VideoSet;
$VideoSetTitle = $VideoSet->title[0];
$numVideos = intval($VideoSet->totalResultsReturned[0]);

$cellsPerRow = 5;
$rows = 5;
$html = createThumbnailTable($VideoSet, $numVideos, $cellsPerRow, $rows);

// the $html variable is displayed in the ResultsDiv below
}

}
catch (Exception $e) {
$html = $e->getMessage();
}

function createThumbnailTable($VideoSet, $numVideos, $cellsPerRow, $rows) {

$html = '<table style="width: 100%; margin: 0 0 0 0; border: 0px; border-style: none; border-collapse: collapse;
vertical-align: top;">';
for ($j=0; $j < $rows; $j++) {
$html .= '<tr>';
for ($k=0; $k < $cellsPerRow; $k++) {
$i = ($j * $cellsPerRow) + $k;
$html .= '<td align="center" valign="top" style="padding: 12px 4px 12px 4px;">';
if ($i >= $numVideos) {
$html .= ' ';
}
else {
// get the properties of each video from the VideoSet
// any property of a video can be accessed as $Video->someproperty[0]

$Video = $VideoSet->Video[$i];
$id = $Video->id[0];
$title = $Video->title[0];
$videoUrl = $Video->videoUrl[0];
$thumbnailUrl = $Video->thumbnailUrl[0];

$html .= '<div style="width: 130px;">';
$html .= '<a href="javascript:playVideo(\'' . $videoUrl . '\',' . $id . '); void(0);"><img src="' .
$thumbnailUrl . '" class="thumbnail" alt="click to play video"/></a>';
$html .= '<div><a href="javascript:playVideo(\'' . $videoUrl . '\',' . $id . '); void(0);">' . $title .
'</a></div>';
$html .= '</div>';
}
$html .= '</td>';
}
$html .= '</tr>';
}
$html .= '</table>';
return $html;
}
