I have been getting the error below when i try to enroll users to moodle through enrol_manual_enrol_users

Array ( [exception] => invalid_parameter_exception [errorcode] => invalidparameter [message] => Invalid parameter value detected [debuginfo] => enrolments => Invalid parameter value detected: Missing required key in single structure: roleid )

This is my code

$MoodleRest = new MoodleRest('http://localhost/moodle/webservice/rest/server.php', $this->token);
$enrolment = array(
"userid" => $user_id,
"courseid" => $course_id,
"roleid" => 4
);
$enrolments = array(array($enrolment));
$params = array( 'enrolments' => $enrolments );
$result_query = $MoodleRest->request('enrol_manual_enrol_users', $params);
if (!empty($result_query['exception'])) {
print_r(array('Error querying enroll', $result_query));
die();
}

I suspect you have too many arrays nested. Your output will look like:

[
    'enrolements' => [
        [
             [
                 [
                     'userid' => 1,
                      ....
                 ],
             ],
        ],
    ],
]

Instead of like:

[
    'enrolements' => [
        [
            'userid' => 1,
            ....
        ],
    ],
]

Hey i am glad you replied but i already tried reducing the nested arrays and it was giving me another error

Array ( [0] => Error querying enroll [1] => Array ( [exception] => invalid_parameter_exception [errorcode] => invalidparameter [message] => Invalid parameter value detected [debuginfo] => Context does not exist ) )

The Less nested arrays are as follows :
$enrolment = array(
"userid" => $user_id,
"courseid" => $course_id,
"roleid" => 4
);
$enrolments = array($enrolment);
$params = array( 'enrolments' => $enrolments );

The error suggests that at least one value you are passing to the web service does not exist.

Have you verified that both the userid and courseid being passed exist in the Moodle instance you are querying?

You may also want to check that the account that you are logging into the webservice as has the correct permissions to view and enrol users onto the course (although I would expect a different error for that)
