实体分析

项目（文章）实体

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);
    }
}

处理程序模式

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);
    }
}

权限系统

权限类型

权限	描述
publisher_view	查看category/articles
publisher_submit	提交新文章
publisher_approve	自动-approve提交
publisher_moderate	审核未决文章
publisher_global	全局模区块权限

权限检查

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()
        );
    }
}

模板结构

前端模板

模板	目的
publisher_index.tpl	模区块主页
publisher_item.tpl	单篇
publisher_category.tpl	类别列表
publisher_submit.tpl	提交表格
publisher_search.tpl	搜索结果

区块模板

模板	目的
publisher_block_latest.tpl	最近的文章
publisher_block_spotlight.tpl	专题文章
publisher_block_category.tpl	类别菜单

使用的关键模式

1. Handler Pattern - 数据访问封装
2. 值对象 - 状态常量
3. 模板方法 - 表单生成
4. 策略 - 不同的显示模式
5. 观察者 - 事件通知

模区块开发经验教训

1. 使用 XOOPSPersistableObjectHandler 进行 CRUD
2. 实施细化权限
3. 将表示与逻辑分开
4. 使用 Criteria 进行查询 5.支持多种内容状态
5. 与XOOPS通知系统集成
