Entity-Analyse

Item (Artikel) Entity

class Item extends \XoopsObject
{
    // Fields
    public function initVar(): void
    {
        $this->initVar('itemid', XOBJ_DTYPE_INT, null, false);
        $this->initVar('categoryid', XOBJ_DTYPE_INT, 0, false);
        $this->initVar('title', XOBJ_DTYPE_TXTBOX, '', true);
        $this->initVar('subtitle', XOBJ_DTYPE_TXTBOX, '');
        $this->initVar('summary', XOBJ_DTYPE_TXTAREA, '');
        $this->initVar('body', XOBJ_DTYPE_TXTAREA, '', true);
        $this->initVar('uid', XOBJ_DTYPE_INT, 0);
        $this->initVar('status', XOBJ_DTYPE_INT, 0);
        $this->initVar('datesub', XOBJ_DTYPE_INT, time());
        // ... more fields
    }

    // Business methods
    public function isPublished(): bool
    {
        return $this->getVar('status') == _PUBLISHER_STATUS_PUBLISHED;
    }

    public function canEdit(int $userId): bool
    {
        return $this->getVar('uid') == $userId
            || $this->isAdmin($userId);
    }
}

Handler Pattern

class ItemHandler extends \XoopsPersistableObjectHandler
{
    public function __construct(\XoopsDatabase $db)
    {
        parent::__construct(
            $db,
            'publisher_items',
            Item::class,
            'itemid',
            'title'
        );
    }

    public function getPublishedItems(int $limit = 10): array
    {
        $criteria = new \CriteriaCompo();
        $criteria->add(new \Criteria('status', _PUBLISHER_STATUS_PUBLISHED));
        $criteria->setSort('datesub');
        $criteria->setOrder('DESC');
        $criteria->setLimit($limit);

        return $this->getObjects($criteria);
    }
}

Berechtigungssystem

Berechtigungstypen

Permission	Description
publisher_view	View category/articles
publisher_submit	Submit new articles
publisher_approve	Auto-approve submissions
publisher_moderate	Review pending articles
publisher_global	Global module permissions

Permission Check

class PermissionHandler
{
    public function isGranted(string $permission, int $categoryId): bool
    {
        $userId = $GLOBALS['xoopsUser']?->uid() ?? 0;
        $groups = $this->getUserGroups($userId);

        return $this->grouppermHandler->checkRight(
            $permission,
            $categoryId,
            $groups,
            $this->helper->getModule()->mid()
        );
    }
}

Verwendete Schlüsselmuster

1. Handler-Muster - Datenzugriffskapselung
2. Value Object - Statuskonstanten
3. Template Method - Formulargenerierung
4. Strategy - Verschiedene Anzeigemodi
5. Observer - Benachrichtigungen bei Ereignissen

Lektionen für die Modulentwicklung

1. Verwende XoopsPersistableObjectHandler für CRUD
2. Implementiere granulare Berechtigungen
3. Trennung von Präsentation und Logik
4. Verwende Criteria für Abfragen
5. Unterstütze mehrere Content-Status
6. Integriere dich mit dem XOOPS-Benachrichtigungssystem
