[FLOW3-general] Weight / compound error messages

[Adrian Föder]

Hi again,

again a general issue, happening on a concrete use case of mine that'll 
explain what I mean.

I want to validate an image upload, it's annotated with two validators:

* @FLOW3\Validate([...]SizeValidator, options={ "minimumWidth"=180, 
"minimumHeight"=180 })
* @FLOW3\Validate([...]TypeValidator, options={ 
"allowedTypes"={"jpeg","png","gif"} })

When uploading a text file for example, I satisfyingly get the following 
errors:

1319801362: The actual image width of 0 is lower than the allowed 
minimum width of 180.

1319801925: The actual image height of 0 is lower than the allowed 
minimum height of 180.

1328030664: The uploaded file is no valid image.

That's fine, but you could imaging that I want to have kind of two 
stages of validation, first stage would affect >>1328030664: The 
uploaded file is no valid image.<<, next stage would affect the 
remaining errors.

Is there already something in planning that accommodates that? For a 
pretty simple solution it would even be sufficient to allow setting up 
the ViewHelper to show only e.g. one error at a stage, with a specific 
sort order, maybe

<f:form.validationResults
   for="newImage"
   errorCodeOrder="1328030664,1319801362,1319801925"
   errorLimit="1"
/>

(of course just a draft), or, just coming into mind,

<f:form.validationResults
   for="newImage"
   occurrenceCompilation="[1328030664],[1319801362,1319801925]"
/>


Your thoughts?

Best,
Adrian
