chamilo-wordpress

Chamilo integration plugin for Wordpress

Install

To install this plugin from source, do the following inside the wp-content/plugins/ directory:

git clone https://github.com/chamilo/chamilo-wordpress chamilo

Then go to your Wordpress plugins panel and go to the "Reading" settings page. Locate the "Chamilo connectivity" section and add your Chamilo URL (like "http://my.chamilo.net/"), the admin username ("admin" or any other username you might have set) and the security key (find it in your app/config/configuration.php by looking for "security_key").

Configuring the courses list widget

Go to the widgets section of your Wordpress configuration panel and locate the "Chamilo Courses list" widget. Place it somewhere useful (drag & drop).

That's it! Now you can see the list of courses from your portal (depending on where you placed the widget).

Configuring the attributes in Woocommerce to put the course code or session id to subscribe user

Go to Products/Attributes, create a new with name CHAMILOCODE and other with name CHAMILOSESSIONID

Shortcode to list your list of courses

You can put the shortcode [chamilo_courses_list_by_user] to show a list of course of the user logged in. To work, you need to add a few lines in /main/webservices/user_info.soap.php

define('WS_ERROR_SECRET_KEY', 1); define('WS_ERROR_NOT_FOUND_RESULT', 2); define('WS_ERROR_INVALID_INPUT', 3); define('WS_ERROR_SETTING', 4); /**

• @param string $code

• @return null|soap_fault */ function returnError($code) { $fault = null; switch ($code) { case WS_ERROR_SECRET_KEY: $fault = new soap_fault( 'Server', '', 'Secret key is not correct or params are not correctly set' ); break; case WS_ERROR_NOT_FOUND_RESULT: $fault = new soap_fault( 'Server', '', 'No result was found for this query' ); break; case WS_ERROR_INVALID_INPUT: $fault = new soap_fault( 'Server', '', 'The input variables are invalid o are not correctly set' ); break; case WS_ERROR_SETTING: $fault = new soap_fault( 'Server', '', 'Please check the configuration for this webservice' ); break; }

  return $fault; }

function WSHelperVerifyKey($params) { global $_configuration, $debug; if (is_array($params)) { $secret_key = $params['secret_key']; } else { $secret_key = $params; } //error_log(print_r($params,1)); $check_ip = false; $ip_matches = false; $ip = trim($_SERVER['REMOTE_ADDR']); // if we are behind a reverse proxy, assume it will send the // HTTP_X_FORWARDED_FOR header and use this IP instead if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) { list($ip1) = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']); $ip = trim($ip1); } if ($debug) { error_log("ip: $ip"); } // Check if a file that limits access from webservices exists and contains // the restraining check if (is_file('webservice-auth-ip.conf.php')) { include 'webservice-auth-ip.conf.php'; if ($debug) { error_log("webservice-auth-ip.conf.php file included"); } if (!empty($ws_auth_ip)) { $check_ip = true; $ip_matches = api_check_ip_in_range($ip, $ws_auth_ip); if ($debug) { error_log("ip_matches: $ip_matches"); } } }

if ($debug) {
    error_log("checkip ".intval($check_ip));
}

if ($check_ip) {
    $security_key = $_configuration['security_key'];
} else {
    $security_key = $ip.$_configuration['security_key'];
    //error_log($ip.'-'.$secret_key.'-'.$security_key);
}

$result = api_is_valid_secret_key($secret_key, $security_key);

if ($debug) {
    error_log('WSHelperVerifyKey result: '.intval($result));
}

return $result;

}

And change the function WSCourseListOfUser to that code

function WSCourseListOfUser($username, $signature) { $params['secret_key'] = $signature;

if (!WSHelperVerifyKey($params)) {
    return returnError(WS_ERROR_SECRET_KEY);
}

if (empty($username) or empty($signature)) {
    return -1;
}
$info = api_get_user_info_from_username($username);
$user_id = $info['user_id'];


$courses_list = [];
$courses_list_tmp = CourseManager::get_courses_list_by_user_id($user_id);
foreach ($courses_list_tmp as $index => $course) {
    $course_info = CourseManager::get_course_information($course['code']);
    $courses_list[] = [
        'code' => $course['code'],
        'title' => api_utf8_encode($course_info['title']),
        'url' => api_get_path(WEB_COURSE_PATH).$course_info['directory'].'/',
        'teacher' => api_utf8_encode($course_info['tutor_name']),
        'language' => $course_info['course_language'],
    ];
}

return $courses_list;

}

Roadmap

In the future, we will add:

• a personal list of courses (not all the public ones but just yours)
• a way to create accounts in Chamilo when they're created in Wordpress
• a way to do Single Sign On (avoid double authentication in Wordpress and Chamilo)
