prepareformdata hook form upload rename

**Speedygonzalez** · 13.02.2023, 06:44

Hallo,

vielleicht kann mich mal jemand anstuppsen damit ich meinen Fehler finde.

Ich möchte aus einem Formular welches 3 Upload Felder hat die Upload Daten umbennen Anhand vom Feld Vorname Nachnahme und dem UploadFeld.

Was habe ich bis jetzt gemacht:

Ordner erstellt
system/modules/filerename
system/modules/filerename/config

Datei erstellt
system/modules/filerename/filereame.php

Code:

<?php
use Contao\DataContainer;
use Contao\File;
use Contao\StringUtil;

namespace Contao;

class FileRename extends \Backend
{
    public function prepareFormData(DataContainer $dc)
    {
        // Get the form data
        $formData = $dc->activeRecord->row();
        
        // Get the file object for the upbewerbung field
        $file = FilesModel::findByUuid($formData['upbewerbung']);
        if ($file === null)
        {
            return;
        }
        
        // Set the new file name
        $newFileName = StringUtil::generateAlias($formData['vorname'] . '-' . $formData['nachname'] . '-bewerbung.pdf');
        $file->name = $newFileName;
        $file->save();
        
        // Get the file object for the uplebenslauf field
        $file = FilesModel::findByUuid($formData['uplebenslauf']);
        if ($file === null)
        {
            return;
        }
        
        // Set the new file name
        $newFileName = StringUtil::generateAlias($formData['vorname'] . '-' . $formData['nachname'] . '-lebenslauf.pdf');
        $file->name = $newFileName;
        $file->save();
        
        // Get the file object for the upzeugnis field
        $file = FilesModel::findByUuid($formData['upzeugnis']);
        if ($file === null)
        {
            return;
        }
        
        // Set the new file name
        $newFileName = StringUtil::generateAlias($formData['vorname'] . '-' . $formData['nachname'] . '-zeugnis.pdf');
        $file->name = $newFileName;
        $file->save();
    }
}

system/modules/filerename/config/config.php

Code:

// Register the classes
ClassLoader::addClasses(array
(
    'FileRename' => 'system/modules/filerename/FileRename.php'
));

// Register the hooks
$GLOBALS['TL_HOOKS']['prepareFormData'][] = array('FileRename', 'prepareFormData');

warum machst Du das nicht so, wie im Handbuch beschrieben?

https://docs.contao.org/dev/referenc...epareFormData/

also folgende Datei anlegen src/EventListener/PrepareFormDataListener.php, Inhalt aus Beispiel einfügen + anpassen...

**Speedygonzalez** · 13.02.2023, 11:12

Vielen dank Zonky das hatte ich mir auch angesehen.

Reicht es dann nur die Datei zu erstellen benötige ich dann diese ganze Class Loader sachen nicht nur die Datei in dem von dir genannten Verzeichnis ?

Und vielleicht was ich in einem anderen Beitrag gefunden habe das man in der composer.json das /src eintragen soll falls er es nicht Automatisch lädt.

Ich versuche mal mein Glück bin nur kein PHP Coder und muss mir das zusammen Basteln
