Customizing Error Messages in Validation Rules

[chamyeongdo]

I'm trying to create custom error messages.

For instance, there's a rule called 'different'. I was able to customize the error message for 'different' as follows:

'different' => ':Attribute and :other must be different.',

Reference gist: https://gist.github.com/johnhout/055d2c039cfb7574d657#file-validation-php-L41

I used the :other parameter to write the error message. However, I haven't been able to find any reference in the official documentation or in the source code that explains how the :other value is provided.

Also, for the dimensions rule, I noticed that parameters like :max_width, :max_height are provided.

But I couldn't find any information about this in any part of the official documentation either.

At some point, \Illuminate\Validation\Concerns\ReplacesAttributes::replaceDifferent() is called
That, in return, calls \Illuminate\Validation\Concerns\ReplacesAttributes::replaceSame(), which replaces :other

Hope, that helps!
