Hi,

when i try to associate classes or  users to a course, i get the following error:

Fatal error: Undefined class name 'rolesrights' in F:\WebSites\aprender\claroline\inc\lib\course.lib.php on line 261

and the association is canceled.

I upgrade dokeos from 1.6.2 to 1.6.3.   In 1.6.2  all worked fine.

What can i do to solve this problem ?

It looks like some code from the community release has been added in this 1.6.3 version. I'll fix this and let you know how to solve this.

Ok. You can fix this by replacing the function subscribe_user in the file ~/claroline/inc/lib/course.lib.php by following code:

    /**
     * Subscribe a user to a course. No checks are performed here to see if
     * course subscription is allowed.
     * @see add_user_to_course
     */
    function subscribe_user($user_id, $course_code, $status = STUDENT)
    {
        $user_table = Database :: get_main_table(MAIN_USER_TABLE);
        $course_table = Database :: get_main_table(MAIN_COURSE_TABLE);
        $course_user_table = Database :: get_main_table(MAIN_COURSE_USER_TABLE);

        $status = ($status == STUDENT || $status == COURSEMANAGER) ? $status : STUDENT;

        if (empty ($user_id) || empty ($course_code))
        {
            return false;
        }
        else
        {
            // previously check if the user are already registered on the platform

            $handle = api_sql_query("SELECT status FROM ".$user_table."
                                                        WHERE `user_id` = '$user_id' ");
            if (mysql_num_rows($handle) == 0)
            {
                return false; // the user isn't registered to the platform
            }
            else
            {
                //check if user isn't already subscribed to the course
                $handle = api_sql_query("SELECT * FROM ".$course_user_table."
                                                                    WHERE `user_id` = '$user_id'
                                                                    AND `course_code` ='$course_code'");
                if (mysql_num_rows($handle) > 0)
                {
                    return false; // the user is already subscribed to the course
                }
                else
                {
                    $max_sort = api_max_sort_value('0', $user_id);
                    $add_course_user_entry_sql = "INSERT INTO ".$course_user_table."
                                        SET `course_code` = '$course_code',
                                        `user_id`    = '$user_id',
                                            `status`    = '".$status."',
                                            `sort`  =   '". ($max_sort +1)."'";
                    $result = api_sql_query($add_course_user_entry_sql);
                    if ($result )
                    {
                        return true;
                    }
                    else
                    {
                        return false;
                    }
                }
            }
        }
    }

If I download the 1.6.3 file from the Dokeos-site (to do an upgrade from 1.6.2), is this bug still there or is it already fixed in that download?

Hello,

i've made the changes, and now i get this error:

Fatal error: Call to undefined function: api_max_sort_value() in
F:/ WebSites/aprender/claroline/ inc/lib/course.lib.php on line 286

thanks.

[pcvowd]

same problem here

[pcool]

api_max_sort_value() is probably named max_sort_value() in your installation.
try to replace api_max_sort_value() by max_sort_value()

[TL]

Everything OK now THNKS

[pcvowd]

In what file do I replace that?

[bmollet]

[ndorotea]

Perfect.

Thanks

[pcvowd]

Problem solved.

Thank you !
