Extend validation

[timhuijser]

Hi Jonathan,

Right now I'm trying to add dynamic validation of a cropped image. How can I extend the CropValidator or the AbstractImageValidator to achieve this?

The image sizes are managed in a separate yaml file and I would like to only declare them once, not twice, for a liip filter and the crop validation. I wrote a provider to retrieve the image sizes from the yaml file. I then should pass it to the configuration of the validator in some way.

Hope you can help!

Can you post an example of your custom yaml configuration file for image sizes ?

Is it really an issue to have this information duplicated ? From my experience, these kind of thing do not change a lot. You will lose a lot of time for this optimization with little benefit in my opinion.

If you already have all information mandatory for the crop validator in a service, you can inject it directly in the service by overriding the default one :

jb_fileupload.crop.validator:
        class: "%jb_fileupload.image.crop.class%"
        tags:
            - { name: jb_fileuploader.validator, alias: Crop }

You can either completly override this validator service to inject your provider as an argument or create a custom compiler pass to add your provider as an argument in the default jb_fileupload.crop.validator and override the class to change the implementation. I had a blog post on the last solution (http://blog.bouzekri.net/2015/02/02/surcharger-n-importe-quel-service-symfony/) but it is in french ...

Thank you for your fast reply! I think for now I will just duplicate the information, it's the easiest way. It was more an optimisation. Right now I'm diving into Symfony, I will return and try your suggestions when I'm more advanced ;). Thank you for your help!
