I'm not sure why you need to add "id" and maybe you should remove the quotes around "false" when defining the "bCreateToken" paramenter.
Code:
<?php
require_once 'pathTo/jsonRPCClient.php';
define( 'LS_BASEURL', 'https://pathTo/limesurvey/');
define( 'LS_USER', 'admin' );
define( 'LS_PASSWORD', 'password' );
$iSurveyID = $_GET["sid"];
$token = $_GET["token"];
$email = $_GET["email"];
$firstName = $_GET["firstname"];
$lastName = $_GET["lastname"];
$language = $_GET["lang"];
// Instantiate a new RPC client
$myJSONRPCClient = new jsonRPCClient( LS_BASEURL.'/index.php/admin/remotecontrol' );
// Get a session key
$sSessionKey= $myJSONRPCClient->get_session_key( LS_USER, LS_PASSWORD );
// Check if token already exists
$tokenExists = false;
$aConditions = array("completed"=>"N");
$listParticipants = $myJSONRPCClient->list_participants($sSessionKey, $iSurveyID, 0, 100000, false, false, $aConditions);
foreach ($listParticipants as $value) {
if(is_array($value)) {
if(array_key_exists('token', $value)) {
if($value['token'] == $token) {
$tokenExists = true;
}
}
}
}
// Token does not exist so we'll create one
if($tokenExists == false) {
// Define the token params
$tokenParams = array("email"=>$email,"lastname"=>$lastName,"firstname"=>$firstName,"token"=>$token,"language"=>$language,"emailstatus"=>"OK");
$aParticipantData=array($tokenParams);
$bCreateToken = false;
// Create the token in survey 2
$newToken = $myJSONRPCClient->add_participants( $sSessionKey, $iSurveyID, $aParticipantData, $bCreateToken);
// If token successfully created, redirect to survey
if(isset($newToken[0]['tid']) && isset($newToken[0]['token'])) {
echo('New token '.$newToken[0]['token'].', ID '.$newToken[0]['tid']);
}
// Otherwise, display errors
else if (isset($newToken['status'])) {
echo $newToken['status'];
}
else {
echo '<br />';
echo 'Error: '.$newToken[0]['errors']['token'][0];
}
}
// Token already exists
else {
echo 'The token already exists!';
}
// Release the session key
$myJSONRPCClient->release_session_key( $sSessionKey );
?>
