Hi,
I'm trying to create my own custom function for webservice using this tutorial:
https://docs.moodle.org/dev/Adding_a_web_service_to_a_plugin
But when i call it it shows this error:
{"exception":"invalid_parameter_exception","errorcode":"invalidparameter","message":"Detectado valor de par\u00e1metro no v\u00e1lido","debuginfo":null}I'm calling this way:
<?php
$token = '48b69d293d73a973997d5f95';
$domainname = 'http://mydomain.com/moodle';
$functionname = 'local_myplugin_create_groups';
$restformat = 'json';
$group = new stdClass();
$group->name = 'Nou grup prueba';
$group->courseid = 8;
$group->description='grupo prueba función';
$group->enrolmentkey='dadss';
$groups = array( $group);
$params = array('groups' => $groups);
/// REST CALL
header('Content-Type: text/plain');
$serverurl = $domainname . '/webservice/rest/server.php'. '?wstoken=' . $token . '&wsfunction='.$functionname;
require_once('./curl.php');
$curl = new curl;
$restformat = ($restformat == 'json')?'&moodlewsrestformat=' . $restformat:'';
$resp = $curl->post($serverurl . $restformat, $params);
print_r($resp);
?>
And my externallib.php :
require_once($CFG->libdir . "/externallib.php");
class local_myplugin_external extends external_api {
/**
* Returns description of method parameters
* @return external_function_parameters
*/
public static function create_groups_parameters() {
return new external_function_parameters(
array(
'groups' => new external_multiple_structure(
new external_single_structure(
array(
'courseid' => new external_value(PARAM_INT, 'id of course'),
'name' => new external_value(PARAM_TEXT, 'multilang compatible name, course unique'),
'description' => new external_value(PARAM_RAW, 'group description text'),
'enrolmentkey' => new external_value(PARAM_RAW, 'group enrol secret phrase'),
)
)
)
)
);
}
public static function create_groups_returns() {
return new external_multiple_structure(
new external_single_structure(
array(
'id' => new external_value(PARAM_INT, 'group record id'),
'courseid' => new external_value(PARAM_INT, 'id of course'),
'name' => new external_value(PARAM_TEXT, 'multilang compatible name, course unique'),
'description' => new external_value(PARAM_RAW, 'group description text'),
'enrolmentkey' => new external_value(PARAM_RAW, 'group enrol secret phrase'),
)
)
);
}
/**
* Create groups
* @param array $groups array of group description arrays (with keys groupname and courseid)
* @return array of newly created groups
*/
public static function create_groups($groups) { //Don't forget to set it as static
global $CFG, $DB;
require_once("$CFG->dirroot/group/lib.php");
$params = self::validate_parameters(self::create_groups_parameters(), array('groups'=>$groups));
$transaction = $DB->start_delegated_transaction(); //If an exception is thrown in the below code, all DB queries in this code will be rollback.
$groups = array();
foreach ($params['groups'] as $group) {
$group = (object)$group;
if (trim($group->name) == '') {
throw new invalid_parameter_exception('Invalid group name');
}
if ($DB->get_record('groups', array('courseid'=>$group->courseid, 'name'=>$group->name))) {
throw new invalid_parameter_exception('Group with the same name already exists in the course');
}
// now security checks
$context = get_context_instance(CONTEXT_COURSE, $group->courseid);
self::validate_context($context);
require_capability('moodle/course:managegroups', $context);
// finally create the group
$group->id = groups_create_group($group, false);
$groups[] = (array)$group;
}
$transaction->allow_commit();
return $groups;
}
}
Anyone can help me?
Thanks
