Ein Hook ist simpel: Von der bekannten Modulstruktur benötigt man nur die /config/config.php, in der man Klasse und Funktion an den gewünschten Hook hängt:
|
1 |
$GLOBALS['TL_HOOKS']['postUpload'][] = array('ZipUploadCustom', 'handleFiles'); |
Sowie die Klasse als solche (direkt im Modulordner):
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
// extend System to have access to the logger: class ZipUploadCustom extends System { public function handleFiles($arrFiles) { foreach ($arrFiles as $file) { $file = TL_ROOT . '/' . $file; if(substr(strtolower($file), -4) === '.zip') { $this->extractZIP($file); } } } // ... } |
Das war’s im Wesentlichen. Der Vollständigkeit halber hier noch die Funkion zum Entpacken, sowie ein wenig Aufräumen der hochgeladenen Dateien:
