Error Handling
As Services_Ebay is a PHP 5 only package, it uses exception handling and the PEAR_Exception class as base class for all exceptions. Exceptions can be thrown, whenever you try to call any of the API calls provided by Services_Ebay, which means you should always nest those in a try/catch-block:
Exception handling
<?php
require_once 'Services/Ebay.php';
// pass some authentication data
$session = Services_Ebay::getSession($devId, $appId, $certId);
$session->setToken($token);
// create new proxy object
$ebay = new Services_Ebay($session);
try {
// call a method
echo $ebay->GeteBayOfficialTime();
} catch (Exception $e) {
echo "Something went wrong.";
echo $e;
}
?> When calling a non-existent API call or passing the wrong parameters to the API, eBay will abort the API call and return an XML-document that contains error information. Services_Ebay will automatically convert this into an exception that can be easily handled by your PHP application.
Warnings in Services_Ebay
In some cases, the eBay API will still process your request, even if you passed invalid parameters and include error information in the resulting XML-document alongside the actual response of your request.
In this case, the errors will be tagged as warnings, as they were not serious errors. Services_Ebay will not convert these errors to exceptions, but only to instances of Services_Ebay_Error. These objects will be stored in the Services_Ebay_Session and can be retrieved by your application at a later point.
Handling warnings
<?php
require_once 'Services/Ebay.php';
// pass some authentication data
$session = Services_Ebay::getSession($devId, $appId, $certId);
$session->setToken($token);
// create new proxy object
$ebay = new Services_Ebay($session);
try {
// call a method
echo $ebay->GeteBayOfficialTime();
} catch (Exception $e) {
// Just ignore the exception and handle them
// with any warnings, that might have occured.
}
$errors = $session->getErrors();
if (count($errors) == 0) {
echo "No errors or warnings.\n";
} else {
foreach ($errors as $error) {
printf("%s: %s (%d))\n", $error->getSeverity(), $error->getLongMessage(), $error->getCode());
}
}
