Hi

I have a question, I’m building a press release section with a data object in 3.1. I want to upload pdf files with the function that if the file already exist that he not overwrite it but just add a number to it.
I see there is a setting “setReplaceFile” that would do that, but whatever I do it does not seem to work.

Any tips on how to get this to work?

This is what I have so far

public function getCMSFields() {
    $fields = parent::getCMSFields();
    $fields->addFieldToTab('Root.Main', DateField::create('Date','Date of Press Release')
      ->setConfig('showcalendar', true));
    $fields->addFieldToTab('Root.Main', TextField::create('Headline','Headline'));
    $fields->addFieldToTab('Root.Main', HtmlEditorField::create('Excerpt')->setDescription('Add something like the first paragraph of the press release'));
    $fields->addFieldToTab('Root.Main', $PressReleases = UploadField::create('PressRelease','PressRelease file (PDF only)'));

    $PressReleases
      ->setFolderName('ShowPro/press/PressRelease')
      ->getValidator()->setAllowedExtensions(array('pdf'));
    $PressReleases->getUpload()->setReplaceFile(false);
    return $fields;
  }

This topic is probably well solved by now, but just to perhaps suggest for future users (and in case it isn't solved), you might be interested in something like the DMS module.
http://addons.silverstripe.org/add-ons/silverstripe/dms

It handles document versioning amongst other things (such as binding a document to a page, which sounds rather useful in your case).

Do you mean that this is a known bug but has not been fixed yet?

OK, figured it out and for anybody else with the same problem you also have to set "setOverwriteWarning(false)" otherwise it will not work
