[11.x] Add case sensitive replacements in validation messages

[fabio-ivona]

premise

Until now, when a validation message is generated after a validation failure, just the :attribute replacement is case-sensitive:

// lang/en/validation.php
<?php
return [
    //..
    'required_with' => 'The :Attribute field is required when :value is present.', // or :ATTRIBUTE for uppercase
    //..
];

results in: The Email field is required when foo is present. (or EMAIL, if :ATTRIBUTE was used)

description

this pull request implements the same behavior also for other replacements in messages for:

• present_if
• present_unless
• present_with (along with present_with_all)
• required_with (along with required_with_all, required_without and required_without_all)
• required_if
• required_if_accepted
• required_if_declined
• required_unless
• prohibited_if
• prohibited_unless
• prohibits

this will allow case-sensitive replacements like this one:

// lang/en/validation.php
<?php
return [
    //..
    'required_with' => 'The :Attribute field is required when :Value is present.', // or :ATTRIBUTE for uppercase
    //..
];

will now result in: The Email field is required when Foo is present. (or EMAIL/FOO, if :ATTRIBUTE/:VALUE was used)

Thanks for your pull request to Laravel!

Unfortunately, I'm going to delay merging this code for now. To preserve our ability to adequately maintain the framework, we need to be very careful regarding the amount of code we include.

If applicable, please consider releasing your code as a package so that the community can still take advantage of your contributions!
