php
// Hook into the user synchronization process
add_action('eb_user_synchronization', 'sync_additional_user_data', 10, 2);

function sync_additional_user_data($moodle_user, $wp_user_id) {
    // Fetch custom data from Moodle user object
    $custom_field_value = $moodle_user->customfield; // Example custom field

    // Update WordPress user meta
    update_user_meta($wp_user_id, 'custom_field', $custom_field_value);
}

2. Custom Login Redirect

To redirect users to a specific page after logging in via Edwiser Bridge SSO, you can add a custom login redirect function.

php
// Hook into the login redirect process
add_filter('login_redirect', 'custom_login_redirect', 10, 3);

function custom_login_redirect($redirect_to, $request, $user) {
    // Check if the user is logging in through Edwiser Bridge
    if (isset($user->ID) && get_user_meta($user->ID, 'eb_user_moodle_id', true)) {
        return home_url('/custom-dashboard'); // Redirect to custom dashboard
    }
    return $redirect_to;
}

Custom API Integration

1. Fetch Moodle Courses and Display on WordPress

Using Moodle's REST API, you can fetch course data and display it on a WordPress page.

In WordPress:

  1. Create a function to fetch courses from Moodle.
  2. Display the courses on a WordPress page.
php
function fetch_moodle_courses() {
    $moodle_url = 'https://your-moodle-site.com/webservice/rest/server.php';
    $token = 'your_moodle_api_token';
    $function_name = 'core_course_get_courses';
    $url = "$moodle_url?wsfunction=$function_name&moodlewsrestformat=json&wstoken=$token";

    // Make the API request
    $response = wp_remote_get($url);
    if (is_wp_error($response)) {
        return [];
    }
    
    $courses = json_decode(wp_remote_retrieve_body($response), true);
    return $courses;
}

function display_moodle_courses() {
    $courses = fetch_moodle_courses();
    if (empty($courses)) {
        return 'No courses found.';
    }

    $output = '<ul>';
    foreach ($courses as $course) {
        $output .= '<li>' . esc_html($course['fullname']) . '</li>';
    }
    $output .= '</ul>';

    return $output;
}

// Shortcode to display Moodle courses
add_shortcode('moodle_courses', 'display_moodle_courses');

Place [moodle_courses] shortcode in any WordPress page to display the list of Moodle courses.

2. Enroll User in Moodle Course from WordPress

To enroll a user in a Moodle course from WordPress, you can create a function that makes an API request to Moodle's enrollment endpoint.

In WordPress:

  1. Create a function to enroll users.
  2. Call this function when needed, such as upon purchasing a course.
php
function enroll_user_in_moodle_course($user_id, $course_id) {
    $moodle_url = 'https://your-moodle-site.com/webservice/rest/server.php';
    $token = 'your_moodle_api_token';
    $function_name = 'enrol_manual_enrol_users';

    // Get Moodle user ID from WordPress user ID (if stored)
    $moodle_user_id = get_user_meta($user_id, 'moodle_user_id', true);
    if (!$moodle_user_id) {
        return false;
    }

    $data = [
        'enrolments' => [
            [
                'roleid' => 5, // Student role ID
                'userid' => $moodle_user_id,
                'courseid' => $course_id
            ]
        ]
    ];

    $url = "$moodle_url?wsfunction=$function_name&moodlewsrestformat=json&wstoken=$token";
    $response = wp_remote_post($url, [
        'body' => $data,
        'headers' => ['Content-Type' => 'application/json']
    ]);

    if (is_wp_error($response)) {
        return false;
    }

    return true;
}

// Example usage: Enroll user 2 in course 3
enroll_user_in_moodle_course(2, 3);

Embedding Moodle Content in WordPress

To embed Moodle content using iframes, you can create a shortcode in WordPress.

php
function embed_moodle_content($atts) {
    $atts = shortcode_atts([
        'url' => '',
        'width' => '100%',
        'height' => '600px'
    ], $atts);

    if (empty($atts['url'])) {
        return 'No URL provided.';
    }

    return '<iframe src="' . esc_url($atts['url']) . '" width="' . esc_attr($atts['width']) . '" height="' . esc_attr($atts['height']) . '"></iframe>';
}

// Shortcode to embed Moodle content
add_shortcode('embed_moodle', 'embed_moodle_content');

Place [embed_moodle url="https://your-moodle-site.com/course/view.php?id=2"] in any WordPress page to embed the Moodle course page.
