working with api call adding form to revise results

[system]

Hello,

I am working with the EBAY Finding API tutorial file which is mainly everything inside the code below except the form field added to the results. I am trying to add a form at the end of the results to perform the search again with different keywords. Upon entering a new keyword and clicking go it seems that the page is loading the updated keywords as it is reflecting them in the “eBay Search Results for” $query variable from the form, but the search results are not changing.

Any help would be greatly appreciated for this noob.

you are explicitly setting the query to harry potter at the beginning of the script, and not passing the GET to it when it runs. therefore all you are doing is displaying the new query, you never passed it for processing. change the file to this:

[php]<?php

error_reporting(E_ALL); // Turn on all errors, warnings and notices for easier debugging

// API request variables
$endpoint = ‘http://svcs.ebay.com/services/search/FindingService/v1’; // URL to call
$version = ‘1.0.0’; // API version supported by your application
$appid = ‘OMITTED FOR PRIVACY’; // Replace with your own AppID
$globalid = ‘EBAY-US’; // Global ID of the eBay site you want to search (e.g., EBAY-DE)

if (empty($_GET[‘newkeywords’])) {
$query = ‘harry potter’; // You may want to supply your own query
} else {
$query = $_GET[‘newkeywords’];
}
$safequery = urlencode($query); // Make the query URL-friendly
$i = ‘0’; // Initialize the item filter index to 0

// Create a PHP array of the item filters you want to use in your request
$filterarray =
array(
array(
‘name’ => ‘MaxPrice’,
‘value’ => ‘25’,
‘paramName’ => ‘Currency’,
‘paramValue’ => ‘USD’),
array(
‘name’ => ‘FreeShippingOnly’,
‘value’ => ‘true’,
‘paramName’ => ‘’,
‘paramValue’ => ‘’),
array(
‘name’ => ‘ListingType’,
‘value’ => array(‘AuctionWithBIN’,‘FixedPrice’,‘StoreInventory’),
‘paramName’ => ‘’,
‘paramValue’ => ‘’),
);

// Generates an indexed URL snippet from the array of item filters
function buildURLArray ($filterarray) {
global $urlfilter;
global $i;
// Iterate through each filter in the array
foreach($filterarray as $itemfilter) {
// Iterate through each key in the filter
foreach ($itemfilter as $key =>$value) {
if(is_array($value)) {
foreach($value as $j => $content) { // Index the key for each value
$urlfilter .= “&itemFilter($i).$key($j)=$content”;
}
}
else {
if($value != “”) {
$urlfilter .= “&itemFilter($i).$key=$value”;
}
}
}
$i++;
}
return “$urlfilter”;
} // End of buildURLArray function

// Build the indexed item filter URL snippet
buildURLArray($filterarray);

// Construct the findItemsByKeywords HTTP GET call
$apicall = “$endpoint?”;
$apicall .= “OPERATION-NAME=findItemsByKeywords”;
$apicall .= “&SERVICE-VERSION=$version”;
$apicall .= “&SECURITY-APPNAME=$appid”;
$apicall .= “&GLOBAL-ID=$globalid”;
$apicall .= “&keywords=$safequery”;
$apicall .= “&paginationInput.entriesPerPage=3”;
$apicall .= “$urlfilter”;

// Load the call and capture the document returned by eBay API
$resp = simplexml_load_file($apicall);

// Check to see if the request was successful, else print an error
if ($resp->ack == “Success”) {
$results = ‘’;
// If the response was loaded, parse it and build links
foreach($resp->searchResult->item as $item) {
$pic = $item->galleryURL;
$link = $item->viewItemURL;
$title = $item->title;

    // For each SearchResultItem node, build a link and append it to $results
    $results .= "<tr><td><img src=\"$pic\"></td><td><a href=\"$link\">$title</a></td></tr>";

}

}
// If the response does not indicate ‘Success,’ print an error
else {
$results = "

Oops! The request was not successful. Make sure you are using a valid ";
$results .= “AppID for the Production environment.

”;
}
?> <?php $results .= ""; $results .= ""; $results .= ""; $query = $_GET['newkeywords']; ?> eBay Search Results for <?php echo $query; ?> body { font-family: arial,sans-serif;}

eBay Search Results for <?php echo $query; ?>

<?php echo $results;?>

[/php]

specifically this checks $_GET[‘newkeywords’] first, and if it is empty sets the query as harry potter, otherwise it sets the query to whatever the new keyword was.
