YCom Overview

YCom is REDAXO's frontend user-management addon. It plugs into YForm (for forms/datasets) and YRewrite (for permissions on pretty URLs). The result: registration, login, sessions, group permissions, article gating, OTP, external auth — all configured in the backend, consumed in templates.

Plugins shipped with YCom

Plugin	Purpose
auth	Login/logout, sessions, article permissions, brute-force protection, OTP, injections
group	User groups + group-based article/media permissions
media_auth	Media-pool file protection with auth/group checks

Core classes

Class	Purpose
rex_ycom	Base class, table registry
rex_ycom_config	Config access
rex_ycom_user	User model (extends rex_yform_manager_dataset)
rex_ycom_auth	Authentication engine, login/logout, permission checks
rex_ycom_auth_rules	Brute-force protection rules
rex_ycom_user_session	Session management (DB-backed)
rex_ycom_user_token	Token generation/validation
rex_ycom_group	Group model and permission checks
rex_ycom_media_auth	Media file permission checks
rex_ycom_log	User activity logging

User model (rex_ycom_user)

rex_ycom_user extends rex_yform_manager_dataset — use the YOrm methods (see the yform-datasets skill).

Status constants

Constant	Value	Meaning
STATUS_INACTIVE_TERMINATION	-3	Terminated
STATUS_INACTIVE_LOGINS	-2	Deactivated (too many failed logins)
STATUS_INACTIVE	-1	Inactive
STATUS_REQUESTED	0	Requested (pending confirmation)
STATUS_CONFIRMED	1	Confirmed and active
STATUS_ACTIVE	2	Active

Login allowed: status >= 1. Login denied: status <= -1. Pending: status = 0.

Common methods

// Get current logged-in user
$user = rex_ycom_auth::getUser(); // rex_ycom_user|null

// Field access
$user->getValue('login');
$user->getValue('email');
$user->getValue('firstname');
$user->getValue('name');
$user->getValue('status');
$user->getValue('last_login_time');
$user->getValue('last_action_time');
$user->getValue('ycom_groups');

// Group checks
$user->isInGroup($group_id); // bool
$user->getGroups();          // array of group IDs

// Related groups (YOrm collection)
foreach ($user->getRelatedCollection('ycom_groups') as $group) {
    echo $group->getValue('name');
}

// Create user programmatically
rex_ycom_user::createUserByEmail([
    'email'     => '[email protected]',
    'login'     => '[email protected]',
    'password'  => $hashedPassword,
    'firstname' => 'Max',
    'name'      => 'Mustermann',
    'status'    => rex_ycom_user::STATUS_CONFIRMED,
]);

// Update current user
rex_ycom_user::updateUser(['firstname' => 'New Name']);

Extending status options

rex_extension::register('YCOM_USER_STATUS_OPTIONS', function (rex_extension_point $ep) {
    $options = $ep->getSubject();
    $options[3] = 'translate:ycom_account_premium';
    ksort($options);
    return $options;
});

Authentication API (rex_ycom_auth)

Auth status constants

Constant	Value
STATUS_NOT_LOGGED_IN	0
STATUS_IS_LOGGED_IN	1
STATUS_HAS_LOGGED_IN	2
STATUS_HAS_LOGGED_OUT	3
STATUS_LOGIN_FAILED	4

Article permission types

Value	Meaning
0	Inherit from parent (default: accessible to all)
1	Only logged-in users (+ optional group checks)
2	Only NOT logged-in users
3	Accessible to all

Common auth methods

$user = rex_ycom_auth::getUser();

if (rex_ycom_auth::getUser()) { /* logged in */ }

// Check article permission
$article = rex_article::get($id);
rex_ycom_auth::articleIsPermitted($article); // bool

// Programmatic login (e.g. after a custom registration step).
// Each key/value becomes a YOrm where() clause — use real columns,
// not magic names. `login` is a string column, NOT a user id.
rex_ycom_auth::loginWithParams(['id' => $userId]);
rex_ycom_auth::loginWithParams(['email' => $email]);

// Logout (writes log entry, clears stay-logged-in cookie, clears session)
rex_ycom_auth::logout($user);

// Low-level: clear session only (no log entry, no cookie cleanup)
rex_ycom_auth::clearUserSession();

// Session variables
rex_ycom_auth::setSessionVar('key', $value);
rex_ycom_auth::getSessionVar('key', 'string', $default);
rex_ycom_auth::unsetSessionVar('key');

// Check password
rex_ycom_auth::checkPassword($password, $userId); // bool

// Delete user
rex_ycom_auth::deleteUser($id);

Login flow (rex_ycom_auth::init())

1. Checks credentials/session/cookie for login.
2. On STATUS_HAS_LOGGED_IN: redirect to article_id_jump_ok.
3. Checks article permissions via articleIsPermitted().
4. Not permitted + not logged in: redirect to article_id_login.
5. Not permitted + logged in: redirect to article_id_jump_denied.
6. On STATUS_HAS_LOGGED_OUT: redirect to article_id_jump_logout.
7. Processes injections (OTP, password change, terms of use).

Navigation integration

$nav = rex_navigation::factory();
$nav->addCallback('rex_ycom_auth::articleIsPermitted');
echo $nav->show(0, 1, true, true);

This filters out articles the current user isn't allowed to see, with no template changes.

Meta navigation (login/logout button)

$user = rex_ycom_auth::getUser();
$login_article  = rex_ycom_config::get('article_id_login');
$logout_article = rex_ycom_config::get('article_id_logout');

if ($user) {
    echo '<a href="' . rex_getUrl($profile_id) . '">'
         . rex_escape($user->getValue('firstname')) . '</a>';
    echo '<a href="' . rex_getUrl($logout_article) . '">Logout</a>';
} else {
    echo '<a href="' . rex_getUrl($login_article) . '">Login</a>';
    echo '<a href="' . rex_getUrl($register_id) . '">Registrieren</a>';
}

Configuration keys (rex_ycom_config::get())

Override via the YCOM_CONFIG extension point.

Common pitfalls

• Treating rex_ycom_auth::getUser() as a guaranteed user object — it returns null when nobody is logged in. Always check.
• Reading status with == against STATUS_REQUESTED (0) without checking for false-positives — null == 0 is true in loose comparison. Use === or constants.
• Forgetting that articleIsPermitted() doesn't redirect on its own — it just returns bool. The redirect happens inside rex_ycom_auth::init().
• Hardcoding article IDs in templates — always pull from rex_ycom_config::get('article_id_login') etc., so the editor can change them in the backend.
• Calling loginWithParams() from a context where the response was already sent — login sets headers (cookie + redirect), must run before output.
• Passing a user id as ['login' => $userId] to loginWithParams() — login is the string login name, not the id. Use ['id' => $userId] or ['email' => $email].
• Using clearUserSession() as the user-facing logout — it skips the log entry and stay-logged-in cookie cleanup. Use rex_ycom_auth::logout($user) for the full flow.
