support rules as array for multiple file uploads

[simonbuehler]

allows rules for multiple files like
->rules(['files' => 'between:1,3', 'files.*' => 'required|max:1024']) so not only the individual file properties are validated but also e.g. the min/max number of uploaded files

[simonbuehler]

found a error when submitting , please don't merge

[simonbuehler]

works so far, rules can either be

only per File Validation

FileUpload::make('Uploads', 'files')
->multiple()
->rules('required|mimes:pdf,png,jpg,jpeg,gif|max:1024')

or also for the Files Collection as well like setting it to be required or min/max number of files

FileUpload::make('Uploads', 'files')
->multiple()
->rules(['files' => 'between:1,3', 'files.*' => ['required','mimes:pdf,png,jpg,jpeg,gif','max:1024']])

Only i can't show the errors for the 'files', they are detected (e.g. no files uploaded) on submit and returned in the "errors" array but not picked up by the form, any hint on this? edit: fixed in layout

What is your reason for this change?

I guess if you have multiple rules it means that the field is set to be multiple?

[simonbuehler]

this would allow to use multiple and only check the individual files ( field.name.*) or check the array (field.name) for backwards compatibility (or both)

the old behaviour was to either show only the individual files error (for multiple set) or the single file error (multiple not set)
