[5.7] Show displayable values for relative dates in validation error messages

[sebdesign]

Currently the after, after_or_equal, before, before_or_equal and date_equals validation rules allow us to use relative keywords in english to compare dates, e.g. date_equals:tomorrow.

When the placeholders are replaced in the validation messages, the :date parameter is normally replaced if it references another attribute, e.g. after:start_date but not when it's a relative keyword.

This is an issue when the locale is other than english: e.g. the date_equals:tomorrow in french is translated to Le champ date doit être une date égale à tomorrow.

This commit allows for developers to specify custom translation for these values.

E.g. in fr/validation.php:

'values' => [
    'date' => [
        'tomorrow' => 'demain',
    ],
],

So now the validation message will be translated to Le champ date doit être une date égale à demain.

getDisplayableValue only takes 1 parameter. Why are you passing two?

[sebdesign]

@taylorotwell if I'm not mistaken it actually takes two parameters:

framework/src/Illuminate/Validation/Concerns/FormatsMessages.php

Line 311 in ac74573

public function getDisplayableValue($attribute, $value)

Is that correct?

[taylorotwell]

Heh, sorry.
