Media Selection custom validation

Tomasz Czado asked on July 5, 2019 09:21


is there a way to validate image minimum width and height for field? I have custom page type with field that uses Media Selection form controls. I would like to see if selected image size is not smaller then defined width and height.

Hi Tomasz!

This scenario is not supported by defaul Media Selection control. The easiest would be to specify Validayion rule against your field like this:

Image Text

All you need to do is to implement this custom macro rule ValidateImageSize(mediaUrl, minWidth, minHeight). So in macro rule you need to:

  • get MediaFileInfo object by URL (you can cut image GUID from URL and find by GUID)
  • check media file width and height against your borders, that's it!

How do you specify the object id on the k# validation {}?
