PHP create User in moodle via Webservice - php

Question

I want so connect an external website with a moodle-system. I've already set up the webService and created a token to get access.
I've followed http://www.rumours.co.nz/manuals/using_moodle_web_services.htm set up but in contrast i wanted to realise the connection via REST as in https://github.com/moodlehq/sample-ws-clients/find/master
My approach is to have a moodle class which will handle the data exchange. In first place i just wanted to try to create some new hard coded Users via the webService but it fails with the Moodle-Response:
"invalidrecord Can not find data record in database table external_functions. "
Which seems to me as if i the call was successfully but moodle has a problem to find the "core_user_create_users" function. I've checked the local moodle Database and in the table external_functions is an entry for "core_user_create_users" so i'm kind of confused where moodle doesn't know what to do.
Thats my class:
require_once (DOCUMENT_ROOT.'/tcm/api/moodle/curl.php');
class Moodle {
private $token;
private $domainName; // 'local.moodle.dev';
private $serverUrl;
public function __construct($token, $domainName) {
$this->token = $token;
$this->domainName = $domainName;
$this->serverUrl = $this->domainName . '/webservice/rest/server.php' . '?wstoken=' . $this->token;
echo "initialize Service: $this->serverUrl </br>";
}
public function createUser() {
$functionName = 'core_user_create_users';
/// PARAMETERS - NEED TO BE CHANGED IF YOU CALL A DIFFERENT FUNCTION
$user1 = new stdClass();
$user1->username = 'testusername1';
$user1->password = 'testpassword1';
$user1->firstname = 'testfirstname1';
$user1->lastname = 'testlastname1';
$user1->email = 'testemail1#moodle.com';
$user1->auth = 'manual';
$user1->idnumber = 'testidnumber1';
$user1->lang = 'en';
$user1->theme = 'standard';
$user1->timezone = '-12.5';
$user1->mailformat = 0;
$user1->description = 'Hello World!';
$user1->city = 'testcity1';
$user1->country = 'au';
$preferencename1 = 'preference1';
$preferencename2 = 'preference2';
$user1->preferences = array(
array('type' => $preferencename1, 'value' => 'preferencevalue1'),
array('type' => $preferencename2, 'value' => 'preferencevalue2'));
$user2 = new stdClass();
$user2->username = 'testusername2';
$user2->password = 'testpassword2';
$user2->firstname = 'testfirstname2';
$user2->lastname = 'testlastname2';
$user2->email = 'testemail2#moodle.com';
$user2->timezone = 'Pacific/Port_Moresby';
$users = array($user1, $user2);
$params = array('users' => $users);
/// REST CALL
$serverurl = $this->serverUrl . '&wsfunction=' . $functionName;
require_once (DOCUMENT_ROOT.'/tcm/api/moodle/curl.php');
$curl = new curl;
//if rest format == 'xml', then we do not add the param for backward compatibility with Moodle < 2.2
$restformat = "json";
$resp = $curl->post($serverurl . $restformat, $params);
//print_r($resp);
echo '</br>*************Server Response*************</br>';
var_dump($resp);
}
}
I'm using the curl class from the same github-project which i posted above - moodle is linkng to it in their Documentation..
docs.moodle.org/dev/Creating_a_web_service_client
The entry point of my call is hardcoded right now:
<?php
include_once (DOCUMENT_ROOT.'/tcm/api/moodle/moodle.php');
//entry point of code
if (isset($_POST)){
//token and domain would be in $_POST
$bla = new Moodle('0b5a1e98061c5f7fb70fc3b42af6bfc4', 'local.moodle.dev');
$bla->createUser();
}
Does anyone know how to solve the "invalidrecord Can not find data record in database table external_functions" error or has a different approach/suggestion how i can create my users remotely??
Thanks in advance

Answer 1

I got it finally working with the following code:
class Moodle {
private $token; //'0b5a1e98061c5f7fb70fc3b42af6bfc4';
private $domainName; // 'http://local.moodle.dev';
private $serverUrl;
public $error;
public function __construct($token, $domainName) {
$this->token = $token;
$this->domainName = $domainName;
$this->serverUrl = $this->domainName . '/webservice/rest/server.php' . '?wstoken=' . $this->token;
echo "initialize Service: $this->serverUrl </br>";
}
public function createUser() {
$functionName = 'core_user_create_users';
$user1 = new stdClass();
$user1->username = 'testusername1';
$user1->password = 'Uk3#0d5w';
$user1->firstname = 'testfirstname1';
$user1->lastname = 'testlastname1';
$user1->email = 'testemail1#moodle.com';
$user1->auth = 'manual';
$user1->idnumber = '';
$user1->lang = 'en';
$user1->timezone = 'Australia/Sydney';
$user1->mailformat = 0;
$user1->description = '';
$user1->city = '';
$user1->country = 'AU'; //list of abrevations is in yourmoodle/lang/en/countries
$preferencename1 = 'auth_forcepasswordchange';
$user1->preferences = array(
array('type' => $preferencename1, 'value' => 'true')
);
$users = array($user1);
$params = array('users' => $users);
/// REST CALL
$restformat = "json";
$serverurl = $this->serverUrl . '&wsfunction=' . $functionName. '&moodlewsrestformat=' . $restformat;
require_once (DOCUMENT_ROOT . '/tcm/api/moodle/curl.php');
$curl = new curl();
$resp = $curl->post($serverurl, $params);
echo '</br>************************** Server Response createUser()**************************</br></br>';
echo $serverurl . '</br></br>';
var_dump($resp);
}
}
Info:
For all moodle beginners.. Activating the moodle Debug messages helps a bit. You'll receive an additional error information in the response returned form the server.
