Append file to files field from front-end upload

Hi,

I have successfully set up front end image uploading, and am updating a field in a user account with what is uploaded. This is my current code in a controller:

$portfolioImage = $this->form->data('portfolioImage');

        if(!empty($portfolioImage['name'])) {
          $filename = time() . '-'. $portfolioImage['name'];

          $file = kirby()->user()->createFile([
            'source'   => $portfolioImage['tmp_name'],
            'filename' => $filename,
            'template' => 'image'
          ]);

          kirby()->user()->update([
            'allImages' => $filename
          ]);
    
        }

Which is working great. I want to change how it works a little - instead of replacing the file in allImages with what has just been uploaded, I want to add it to the list of files (allImages has multiple: true set on it). What is the best way of doing this?

Update:

It tried this - the process seems to make sense to me (create an array of the existing images, upload the file, append it to the array, write the array to the content file):

$portfolioImage = $this->form->data('portfolioImage');
$existingImages = kirby()->user()->allImages()->toFiles();
$newImageSet = [];

        foreach($existingImages as $existing):
          $newImageSet[] = $existing->uuid();
        endforeach;

        if(!empty($portfolioImage['name'])) {
          $filename = time() . '-'. $portfolioImage['name'];

          $newfile = kirby()->user()->createFile([
            'source'   => $portfolioImage['tmp_name'],
            'filename' => $filename,
            'template' => 'image'
          ]);

          $newImageSet[] = $newfile->uuid();

          kirby()->user()->update([
            'allImages' => Data::encode($newImageSet, 'yaml')
          ]);
    
        }

But this causes a major error - the file is repeatedly uploaded until the site runs out of memory! It seems to be caught in a loop, as the file name (which includes time()) changes each upload before it crashes. If anyone has any thoughts that would be super!

OK got it - below is working for me:

$portfolioImage = $this->form->data('portfolioImage');

        if(!empty($portfolioImage['name'])) {

          $existingImages = kirby()->user()->allImages()->toFiles();
          $newImageSet = [];

          foreach($existingImages as $existing):
            $newImageSet[] = 'file://' . $existing->uuid()->id();
          endforeach;

          $filename = time() . '-'. $portfolioImage['name'];

          $newfile = kirby()->user()->createFile([
            'source'   => $portfolioImage['tmp_name'],
            'filename' => $filename,
            'template' => 'image'
          ]);

          $newImageSet[] = 'file://' . $newfile->uuid()->id();

          kirby()->user()->update([
            'allImages' => Data::encode($newImageSet, 'yaml')
          ]);
    
        }
