Cangkuk dan Acara

Gambaran KeseluruhanXOOPS menyediakan cangkuk dan acara sebagai titik sambungan yang membolehkan modul berinteraksi dengan fungsi teras dan satu sama lain tanpa kebergantungan langsung.## Cangkuk vs Acara| Aspek | Cangkuk | Peristiwa |

|--------|-------|--------| | Tujuan | Ubah suai behavior/data | Bertindak balas terhadap kejadian | | Kembali | Boleh mengembalikan data yang diubah suai | Lazimnya batal | | Masa | Tindakan Before/during | Selepas tindakan | | Corak | Rantai penapis | Observer/pub-sub |## Sistem Cangkuk### Mendaftar Cangkuk

php
// Register a hook in xoops_version.php
$modversion['hooks'][] = [
    'name'     => 'user.profile.display',
    'callback' => 'mymodule_hook_user_profile',
    'priority' => 10,
];

Panggilan Balik Cangkuk

include/hooks.php

php
function mymodule_hook_user_profile(array $data): array
{
    $userId = $data['user_id'];

    // Add custom profile fields
    $data['fields']['reputation'] = mymodule_get_user_reputation($userId);
    $data['fields']['badges'] = mymodule_get_user_badges($userId);

    return $data;
}

Cangkuk Teras Tersedia| Nama Cangkuk | Data | Penerangan |

|-----------|------|-------------| | user.profile.display | Tatasusunan data pengguna | Ubah suai paparan profil | | content.render | Kandungan HTML | Output kandungan penapis | | form.submit | Data borang | Data borang Validate/modify | | search.results | Susunan keputusan | Tapis hasil carian | | menu.main | Item menu | Ubah suai menu utama |## Sistem Acara### Menghantar Acara

php
// In your module code
$eventHandler = xoops_getHandler('event');

$eventHandler->trigger('mymodule.article.created', [
    'article_id' => $article->id(),
    'author_id'  => $article->authorId(),
    'title'      => $article->title(),
]);

Mendengar Acara

class/Preload.php

php
class MyModulePreload extends \XMF\Module\Helper\AbstractHelper
{
    public function eventMymoduleArticleCreated(array $args): void
    {
        $articleId = $args['article_id'];

        // Notify subscribers
        $this->notifyNewArticle($articleId);
    }

    public function eventUserLogin(array $args): void
    {
        $userId = $args['userid'];

        // Update last login for module
        $this->updateUserActivity($userId);
    }
}

Rujukan Acara Pramuat### Acara Teras

php
// Header/Footer
public function eventCoreHeaderStart(array $args): void {}
public function eventCoreHeaderEnd(array $args): void {}
public function eventCoreFooterStart(array $args): void {}
public function eventCoreFooterEnd(array $args): void {}

// Includes
public function eventCoreIncludeCommonStart(array $args): void {}
public function eventCoreIncludeCommonEnd(array $args): void {}

// Exceptions
public function eventCoreException(array $args): void {}

Acara Pengguna

php
public function eventUserLogin(array $args): void {}
public function eventUserLogout(array $args): void {}
public function eventUserRegister(array $args): void {}
public function eventUserActivate(array $args): void {}
public function eventUserDelete(array $args): void {}

Peristiwa Modul

php
public function eventSystemModuleInstall(array $args): void {}
public function eventSystemModuleUninstall(array $args): void {}
public function eventSystemModuleUpdate(array $args): void {}
public function eventSystemModuleActivate(array $args): void {}
public function eventSystemModuleDeactivate(array $args): void {}

Acara Modul Tersuai### Menentukan Peristiwa

php
// Define event constants
class ArticleEvents
{
    public const CREATED = 'mymodule.article.created';
    public const UPDATED = 'mymodule.article.updated';
    public const DELETED = 'mymodule.article.deleted';
    public const PUBLISHED = 'mymodule.article.published';
}

Mencetuskan Peristiwa

php
class ArticleService
{
    public function publish(Article $article): void
    {
        $article->publish();
        $this->repository->save($article);

        // Trigger event
        $GLOBALS['xoopsPreload']->triggerEvent(
            ArticleEvents::PUBLISHED,
            ['article' => $article]
        );
    }
}

Mendengar Peristiwa Modul

php
// In another module's Preload.php

public function eventMymoduleArticlePublished(array $args): void
{
    $article = $args['article'];

    // Index for search
    $this->searchIndexer->index($article);

    // Update sitemap
    $this->sitemapGenerator->addUrl($article->url());
}

Amalan Terbaik1. Gunakan Nama Tertentu - Format module.entity.action

2. Lulus Data Minimum - Hanya apa yang pendengar perlukan
3. Peristiwa Dokumen - Senaraikan acara dalam dokumen modul
4. Elakkan Kesan Sampingan - Pastikan pendengar fokus
5. Kendalikan Ralat - Jangan biarkan ralat pendengar pecah mengalir## Dokumentasi Berkaitan- Sistem Peristiwa - Dokumentasi acara terperinci
