Custom error message for Laravel validation rule: Dimensions

阅读更多关于 Custom error message for Laravel validation rule: Dimensions

I'm trying to validate an image upload that looks like the following: $this->validate($request, [ 'admin_image'=> 'nullable|image|dimensions:min_width=600,min_height=600', ]); when the selected image too small then laravel shows error: The Admin Image has invalid image dimensiona I think that message is not saying specifically that in which dimension the image small, eg: width or height.

How to Highlight Fields on Rails Validation Errors

阅读更多关于 How to Highlight Fields on Rails Validation Errors

I have already implemented the string display of error messages through: @user.errors.full_messages.each...etc, but I can't get the fields to become highlighted in red. Any ideas? Thanks.
