Penerbit - Kait dan Acara

Kait dan Acara Penerbit

Panduan lengkap untuk memperluas fungsionalitas Publisher menggunakan acara, kait, dan plugin.

Ikhtisar Sistem Acara

Apa Itu Acara?

Peristiwa memungkinkan module lain bereaksi terhadap tindakan Penerbit:

Publisher Action → Trigger Event → Other modules listen/react

Examples:
  - Article created → Send notification email
  - Article published → Update social media
  - Comment posted → Notify author
  - Category created → Update search index

    ));
    curl_exec($ch);
    curl_close($ch);
}
?>

Sistem Kait

Kait Penerbit

Kait memungkinkan modifikasi pada perilaku Penerbit:

penerbit.view.artikel.mulai

Dipanggil sebelum artikel dirender.

xoops_events()->attach(
    'publisher.view.article.start',
    'modify_article_before_display'
);

function modify_article_before_display(&$item) {
    // Modify item before display
    $title = $item->getVar('title');
    $item->setVar('title', '[FEATURED] ' . $title);
}

penerbit.view.artikel.akhir

Dipanggil setelah artikel dirender.

xoops_events()->attach(
    'publisher.view.article.end',
    'append_to_article'
);

function append_to_article(&$article) {
    // Add content after article
    $article .= '<div class="related-articles">';
    $article .= '<!-- Related articles content -->';
    $article .= '</div>';
}

penerbit.izin.periksa

Dipanggil saat memeriksa izin.

xoops_events()->attach(
    'publisher.permission.check',
    'custom_permission_logic'
);

function custom_permission_logic(&$allowed, $permission, $itemId) {
    // Custom permission logic
    if (custom_rule_applies($itemId)) {
        $allowed = true;
    }
}

Sistem Pengaya

Buat Plugin

Plugin memperluas fungsionalitas Publisher:

Struktur File:

modules/publisher/plugins/
├── myplugin/
│   ├── plugin.php (main file)
│   ├── language/
│   │   └── english.php
│   ├── templates/
│   └── css/

plugin.php:

<?php
// Plugin information
define('MYPLUGIN_NAME', 'My Publisher Plugin');
define('MYPLUGIN_VERSION', '1.0.0');
define('MYPLUGIN_DESCRIPTION', 'Extends Publisher with custom features');

// Register hooks/events
xoops_events()->attach(
    'publisher.item.created',
    'myplugin_on_item_created'
);

xoops_events()->attach(
    'publisher.view.article.end',
    'myplugin_append_content'
);

// Plugin functions
function myplugin_on_item_created($data) {
    // Handle item creation
}

function myplugin_append_content(&$content) {
    // Append content to article
    $content .= '<div class="myplugin-content">Custom content</div>';
}

// Plugin API
class MyPublisherPlugin {
    public static function getArticles($limit = 10) {
        $itemHandler = xoops_getModuleHandler('Item', 'publisher');
        return $itemHandler->getRecent($limit);
    }

    public static function getCategoryTree() {
        $catHandler = xoops_getModuleHandler('Category', 'publisher');
        return $catHandler->getRoots();
    }
}
?>

Muat Plugin

Dalam inisialisasi Penerbit:

<?php
// Load plugin
$pluginPath = XOOPS_ROOT_PATH . '/modules/publisher/plugins/myplugin/plugin.php';
if (file_exists($pluginPath)) {
    include_once $pluginPath;
}
?>

Filter

Filter Konten

Filter mengubah pemrosesan data before/after:

<?php
// Filter article title
$title = apply_filters('publisher_item_title', $title, $itemId);

// Filter article body
$body = apply_filters('publisher_item_body', $body, $itemId);

// Filter article display
$display = apply_filters('publisher_item_display', $display, $item);
?>

Daftar Filter

<?php
// Add filter
add_filter('publisher_item_title', 'my_title_filter');

function my_title_filter($title, $itemId) {
    // Modify title
    return strtoupper($title);
}

// Add filter with priority
add_filter(
    'publisher_item_body',
    'my_body_filter',
    10,  // priority (lower = earlier)
    2    // number of arguments
);

function my_body_filter($body, $itemId) {
    // Add watermark to body
    return $body . '<p class="watermark">© ' . date('Y') . '</p>';
}
?>

Kait Tindakan

Tindakan Khusus

Jalankan kode pada titik tertentu:

<?php
// Do action
do_action('publisher_article_saved', $itemId, $item);

// Do action with arguments
do_action('publisher_comment_approved', $commentId, $comment);

// Listen to action
add_action('publisher_article_saved', 'my_action_handler');

function my_action_handler($itemId, $item) {
    // Execute code
    log_article_save($itemId);
    update_statistics();
}
?>

Memperluas dengan Plugin

Contoh Plugin: Artikel Terkait

<?php
class RelatedArticlesPlugin {
    public static function init() {
        xoops_events()->attach(
            'publisher.view.article.end',
            array(__CLASS__, 'displayRelated')
        );
    }

    public static function displayRelated(&$content) {
        // Get related articles
        $related = self::getRelatedArticles();

        if (count($related) > 0) {
            $html = '<div class="related-articles">';
            $html .= '<h3>Related Articles</h3>';
            $html .= '<ul>';

            foreach ($related as $article) {
                $html .= '<li>';
                $html .= '<a href="' . $article->url() . '">';
                $html .= $article->title();
                $html .= '</a>';
                $html .= '</li>';
            }

            $html .= '</ul>';
            $html .= '</div>';

            $content .= $html;
        }
    }

    protected static function getRelatedArticles() {
        // Get current article
        global $itemId;

        $itemHandler = xoops_getModuleHandler('Item', 'publisher');
        $item = $itemHandler->get($itemId);

        if (!$item) {
            return array();
        }

        // Get articles in same category
        $related = $itemHandler->getByCategory(
            $item->getVar('categoryid'),
            $limit = 5
        );

        // Remove current article
        $related = array_filter($related, function($article) {
            global $itemId;
            return $article->getVar('itemid') != $itemId;
        });

        return array_slice($related, 0, 3);
    }
}

// Initialize plugin
RelatedArticlesPlugin::init();
?>

Praktik Terbaik

Pedoman Pendengar Acara

  - my_module_on_publisher_item_created
  - Instead of: process_event_1

✓ Document your events
  - Comment what trigger point is
  - List expected data
  - Show usage examples

✓ Unload listeners properly
  - Clean up on module uninstall
  - Remove hooks when no longer needed

Kiat Kinerja

✗ Avoid database queries in listeners
✗ Don't block execution with slow operations
✗ Avoid modifying data unnecessarily

✓ Queue long-running tasks
✓ Cache external API calls
✓ Use lazy loading for dependencies
✓ Batch database operations

Men-debug Acara

Aktifkan Mode Debug

        'publisher_debug_event'
    );
}

function publisher_debug_event($data) {
    error_log('Publisher Event: ' . print_r($data, true));
}
?>

// Log event data
xoops_events()->attach(
    'publisher.item.created',
    'log_publisher_events'
);

function log_publisher_events($data) {
    $log = XOOPS_ROOT_PATH . '/var/log/publisher.log';
    $entry = date('Y-m-d H:i:s') . ' - ';
    $entry .= 'Event: publisher.item.created' . "\n";
    $entry .= 'Data: ' . json_encode($data) . "\n\n";
