Mehrere Attachments / PDFs einem Mail anhängen

[heyho]

Isotope: Mailanhang

Wie hängt man richtig mehrere Attachments (Dokumente, PDFs, ...) einem Mail an?

Meine Vorgehensweise, nach langem Suchen...

// config.php
$GLOBALS['TL_HOOKS']['initializeSystem'][] = array('Hooks', 'myInitializeSystem');
$GLOBALS['TL_HOOKS']['sendNotificationMessage'][] = array('Hooks', 'addAttachmentsToMail');

// Hooks.php
public function myInitializeSystem( )
{
    /**
     * Attachment-Token für alle Notifications hinzufügen
     */
    foreach( $GLOBALS['NOTIFICATION_CENTER']['NOTIFICATION_TYPE'] as $x=>$y ) {
        foreach( $y as $z=>$h ) {
            $GLOBALS['NOTIFICATION_CENTER']['NOTIFICATION_TYPE'][$x][$z]['email_text'][] = 'file1_document';
            $GLOBALS['NOTIFICATION_CENTER']['NOTIFICATION_TYPE'][$x][$z]['email_html'][] = 'file1_document';
            $GLOBALS['NOTIFICATION_CENTER']['NOTIFICATION_TYPE'][$x][$z]['email_text'][] = 'file2_document';
            $GLOBALS['NOTIFICATION_CENTER']['NOTIFICATION_TYPE'][$x][$z]['email_html'][] = 'file2_document';
            $GLOBALS['NOTIFICATION_CENTER']['NOTIFICATION_TYPE'][$x][$z]['attachment_tokens'][] = 'file1_attachment';
            $GLOBALS['NOTIFICATION_CENTER']['NOTIFICATION_TYPE'][$x][$z]['attachment_tokens'][] = 'file2_attachment';
        }
    }
}


public function addAttachmentsToMail($objMessage, &$arrTokens, $language, $objGatewayModel)
{
    $objGateway = $objGatewayModel->getGateway();
    if ($objGateway instanceof Email) {
    
        /*
         * only if order is paid
         */
         
        $objOrder = Order::findById($arrTokens['order_id']);
        if (! $objOrder->isPaid()) {
            return true; #  muss true sein, damit der weitere Programmablauf nicht abgebrochen wird.
        }
        
        /*
        * Create File dynamicaly or load from somewhere,...
        */
        
        $filepath1 = "/files/somewhere/file1.pdf";
        $filepath2 = "/files/somewhere/file2.docx";
        
        $arrTokens['file1_document'] =  $filepath1;
        $arrTokens['file1_attachment'] = basename($filepath1);
        
        $arrTokens['file2_document'] =  $filepath2;
        $arrTokens['file2_attachment'] = basename($filepath2);
    
    }
    
    return true;

} 

BACKEND
Im Backend müssen diese Attachments beim jeweiligen Benachrichtigung unter "Dateianhänge via Tokens" eingefügt werden.
