[TYPO3-dev] FAL: Remove files in frontend extension

[Klaus Heuer]

Hi Frans,

the debug output was exactly the same, if I add an Image via Backend TCA 
Form or Frontend ...

I solved the image remove function now directly in the controller:

public function savePostAction() {
...
if ($post['imagedelete'] == 1) {
             $images = $DBPost->getImage();
             foreach ($images as $img) {

                  //remove the file reference
                 $reference = 
$this->fileReferenceRepository->findByUid($img->getUid());
$this->fileReferenceRepository->remove($reference);

                 //remove the image in model (only one image allowed)
                 $DBPost->setImage(null);
             }
         }
...

I know, that is not an "ideal solution" but it works;)  The images can 
now added / deleted via Backend TCA Form and Frontend editing (without 
deleting the image file itself).

Thanks for your help,

Klaus
