eBay API SKU missing from response - php

Question

I am trying to download all my listings from ebay into my database using following code:
$client = new eBaySOAP($session);
$ebay_items_array = array();
try {
$client = new eBaySOAP($session);
$params = array(
'Version' => $Version,
'GranularityLevel' => "Fine",
'OutputSelector' => "ItemID,SKU,Title",
'EndTimeFrom' => date("c", mktime(date("H"), date("i")+10, date("s"), date("n"), date("j"), date("Y"))),
'EndTimeTo' => date("c", mktime(date("H"), date("i"), date("s"), date("n"), date("j")+120, date("Y"))),
'Pagination' => array(
'PageNumber' => $_GET['linkebaynum'],
'EntriesPerPage' => "20"
)
);
$results = $client->GetSellerList($params);
if($results->Ack == "Success")
{
$c = 0;
if(is_array($results->ItemArray->Item))
{
foreach($results->ItemArray->Item as $key => $value)
{
array_push($ebay_items_array, $value->ItemID);
$Qcheck = tep_db_query('select ebay_productstoitems_items_id from ' . TABLE_EBAY_PRODUCTS_TO_ITEMS . ' where ebay_productstoitems_items_id = ' . $value->ItemID);
$check = tep_db_fetch_array($Qcheck);
if($check == 0) {
if($check['ebay_productstoitems_items_id'] = $value->ItemID) {
echo 'Not in Database - Inserting ' . $value->ItemID . '<br>';
tep_db_query("insert ebay_productstoitems set ebay_productstoitems_items_id = '" . $value->ItemID . "'");
}
}else{
echo 'Found - ' . $value->ItemID . ' Nothing to Change<br>';
tep_db_query("update ebay_productstoitems set ebay_productstoitems_items_id = '" . $value->ItemID . "' where ebay_productstoitems_items_id = '" . $value->ItemID . "'");
}
}
$c++;
}
}
} catch (SOAPFault $f) {
print "error<br>";
}
print "Request:<br>".ebay_formatxmlstring($client->__getLastRequest())."<br><br>";
print "Response:<br>".ebay_formatxmlstring($client->__getLastResponse())."<br><br>";
But it will not recover the SKU (or CustomLabel).
Can anyone explain what I am missing to get the SKU into the database along with the ItemID.
Or would I have to recover lists of ItemID and then do a second call to recover the SKU or CustomLabel?

Answer 1

Found out what the problem was the Sandbox does not appear to pass the SKU back. I switched to the live site and hey presto the SKU is being retrieved along with the Itemid.
