Date validation - How localize/translate strings "today" and "tomorrow" - laravel

Question

In my model I defined a few validation rules for date fields using before and after:
'birth_date' => 'required|date|before:today|after:01-jan-1920',
'another_date' => 'required|date|before:tomorrow|after:01-jan-1990',
The validation works fine, however I can't figure out how to translate the strings today and tomorrow on the validation message.
In the validation.php language file the after and before messages are localizable, however the :date part of the message is still displaying the English version for today and tomorrow.
"after" => "The :attribute must be a date after :date.",
"before" => "The :attribute must be a date before :date.",
How could I localize those two words - today and tomorrow - in the validation message?

Answer 1

In short, add following code into resources/lang/whichever/validation.php
'values' => [
// or whatever fields you wanna translate
'birth_date' => [
// or tomorrow
'today' => '今天'
]
]
Explained:
https://github.com/laravel/framework/blob/7.x/src/Illuminate/Validation/Concerns/FormatsMessages.php#L319
/**
* Get the displayable name of the value.
*
* #param string $attribute
* #param mixed $value
* #return string
*/
public function getDisplayableValue($attribute, $value)
{
if (isset($this->customValues[$attribute][$value])) {
return $this->customValues[$attribute][$value];
}
// the key we want
$key = "validation.values.{$attribute}.{$value}";
// if the translate found, then use it
if (($line = $this->translator->get($key)) !== $key) {
return $line;
}
if (is_bool($value)) {
return $value ? 'true' : 'false';
}
return $value;
}

You can use custom validation messages per field, either on validation language file or in your code itself: https://laravel.com/docs/5.2/validation#custom-error-messages
Let's simulate a controller validation to see how it works:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Routing\Controller;
class YourController extends Controller
{
public function store(Request $request)
{
$rules = [
'birth_date' => 'required|date|before:today|after:01-jan-1920',
];
$messages = [
'birth_date.before' => 'A data de nascimento deve ser uma data antes de hoje.', // "The birth date must be a date before today" in portuguese
];
$this->validate($request, $rules, $messages);
/* your stuff */
}
}
You can also do that with form requests (which are even nicer), all you need to do is return your custom translated messages inside messages() method. :)

Use custom error messages.
$this->validate(
$request,
[
'phone' => 'required|regex:/^(\d[\s-]?)?[\(\[\s-]{0,2}?\d{3}[\)\]\s-]{0,2}?\d{3}[\s-]?\d{4}$/i'
],
[
'regex' => 'You must enter a valid phone number.',
'required' => 'You must enter a valid phone number.'
]
);
Replace 'regex' and 'required' with 'before:today' and 'before:tomorrow' and replace with custom error messages.

Answer 4

It probably makes more sense to make some custom validations but I think you should be able to do this simply with Carbon:
$dt = new Carbon\Carbon();
$today = $dt->today();
$tomorrow = $dt->tomorrow();
$rules = [
...
'birth_date' => 'required|date|before:'.$today.'|after:01-jan-1920',
'another_date' => 'required|date|before:'.$tomorrow.'|after:01-jan-1990'
];
