💻 1. Extension-Struktur (extensions/MeinCustomTag/)

Ordnerstruktur:

• extensions/MeinCustomTag/extension.json
• extensions/MeinCustomTag/src/Hooks.php

extension.json (Manifest)

{
    "name": "MeinCustomTag",
    "version": "1.0.0",
    "author": "Thorsten",
    "description": "Erweitert MediaWiki um das Tag <customtag>",
    "type": "other",
    "AutoloadNamespaces": {
        "MediaWiki\\Extension\\MeinCustomTag\\": "src/"
    },
    "Hooks": {
        "ParserFirstCallInit": "MediaWiki\\Extension\\MeinCustomTag\\Hooks::onParserFirstCallInit"
    },
    "manifest_version": 2
}

src/Hooks.php (PHP Logik)

<?php
namespace MediaWiki\Extension\MeinCustomTag;

use Parser;

class Hooks {
    public static function onParserFirstCallInit(Parser $parser) {
        $parser->setHook('customtag', [self::class, 'renderCustomTag']);
    }

    public static function renderCustomTag($input, array $args, Parser $parser, $frame) {
        $output = htmlspecialchars($input);
        return "<div class='my-custom-box'><strong>Hinweis:</strong> {$output}</div>";
    }
}

⚡ 2. Aktivieren in LocalSettings.php

wfLoadExtension( 'MeinCustomTag' );
