Laravel validation with lang for input names - php

Question

I have one class named Validator that handles all validations that I need to do, and one class that extends my class with my rules and names for the error.
The problem is, I'm trying to use 'Lang' to get a translated message but it don't work and I don't know why.
Validation class:
<?php namespace App\Services\Validators;
abstract class Validator {
protected $data;
public $errors;
public static $rules;
public static $names;
public function __construct($data = null)
{
$this->data = $data ?: \Input::all();
}
public function passes()
{
$validation = \Validator::make($this->data, static::$rules, array(), static::$names);
if ($validation->passes()) return true;
$this->errors = $validation->messages();
return false;
}
}
My class that extends the validator:
use Lang;
class PrestadorSiteValidator extends Validator {
public static $rules = array(
'nome' => 'required',
'nome_fantasia' => 'required',
'email' => 'required|confirmed',
'identificador' => 'required',
'pais_id' => 'required',
'codigo_postal' => 'required',
'estado' => 'required',
'cidade' => 'required',
'rua' => 'required',
'bairro' => 'required',
);
public static $names = array(
'nome' => Lang::get('site.nome'),
'nome_fantasia' => 'Nome Fantasia',
'email' => 'Email',
'identificador' => 'CNPJ',
'pais_id' => 'País',
'codigo_postal' => 'Código Postal',
'estado' => 'Estado',
'cidade' => 'Cidade',
'rua' => 'Rua',
'bairro' => 'Bairro',
);
}
The error that I get:
syntax error, unexpected '(', expecting ')'
When I try to use:
'nome' => Lang::get('site.nome'),
Can someone please help me? :)

You cannot execute code in a PHP variable definition statement, so, instead of:
public static $names = array(
'nome' => Lang::get('site.nome'),
);
You must do something like
public static $names = array(
'nome' => 'site.nome',
);
EDIT:
To do what you need to do, the way you are doing it, you can, in your abstract validator, override an important method:
<?php namespace App\Services\Validators;
abstract class Validator {
protected function explodeRules($rules)
{
foreach(static::$names as $key => $value)
{
if (starts_with($value, 'lang::'))
{
static::$names[$key] = Lang::get(str_replace("lang::", "", $value));
}
}
return parent::explodeRules($rules);
}
}
Then use it:
public static $names = array(
'nome' => 'lang::site.nome',
'nome_fantasia' => 'Nome Fantasia',
'email' => 'Email',
'identificador' => 'CNPJ',
'pais_id' => 'País',
'codigo_postal' => 'Código Postal',
'estado' => 'Estado',
'cidade' => 'Cidade',
'rua' => 'Rua',
'bairro' => 'Bairro',
);
Not a very clean way of doing it, but it should work.
