download the latest nusoap.php
this is the code i always use to connet such a service:
$soapclient = new soapclient('https://sitename/pagename.asmx?wsdl','wsdl');
if (!$err = $soapclient->getError())
$soapProxy = $soapclient->getProxy() ;
if ( (!$soapclient) OR ($err = $soapclient->getError()) ) {
echo $error ;
return('unsuccessfull');
}
else {
$params = array(
'pin' => $pin , // this is our PIN NUMBER
'amount' => $price,
'orderId' => $orderId,
'callbackUrl' => $callbackUrl,
'authority' => $authority,
'status' => $status
);
$sendParams = array($params) ;
$res = $soapclient->call('methodName', $sendParams);
.....
otherwise, write your code here, specially the line caused error. others will help more.
