Hi all,

I'm still relatively new to SilverStripe and have been trying to get to grips with things since 3.0.0 came out. I'm wondering if there's any way of only allowing certain file types to be uploaded with the UploadField? I can't seem to find anything in the API documentation for it.

I'm interested in limiting it to just images (only for an imaginary client's needs). The 'client' will need to be able to upload hundreds of images per DataObject, so I wasn't sure whether UploadField was the best thing to use.

Thanks

I did try that but I can still upload any type of file :/

This is my implementation of it:

$uploadField = new UploadField('Images');
$uploadField->allowedExtensions = array('jpg', 'gif', 'png');
      
$fields->addFieldToTab("Root.Images", $uploadField);

Thanks
