How could I get the preview image with its metadata via dataProcessing? #37

Hello together, to output image credits at the end of a page, I use the following code for ce textmedia:

`lib.photocredits = FLUIDTEMPLATE lib.photocredits {

[...]

dataProcessing {

Bildnachweis: CE Textmedia

10 = TYPO3\CMS\Frontend\DataProcessing\DatabaseQueryProcessor
10 {
  table = tt_content
  where.data = field:uid
  orderBy = sorting
  as = myrecords
  dataProcessing {
   10 = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
   10 {
     references.fieldName = assets
     as = image
   }
 }

} }

Fluid-Ausgabe:

{image.properties.copyright}`

This works for videos and images and would need to add the preview image to it. I hope someone can help me with this.

Thanks a lot Ulli

Sry i don't know how we can nest the dataProcessing thing correctly. But you can try to use a custom viewhelper like this one below:

<?php
