Laravel 5.5 Multilanguage validation - ajax

Question

Please tell me, I ran into a problem. There is a site based on Laravel 5.5. The site has a multilanguage (two languages en/ru). For multilanguage I'm using:
dimsav/laravel-translatable
mcamara/laravel-localization
Added language files to the directory resources/lang/ru. The problem is the validation of the form. The site has a feedback form in the modal window, working with ajax (sending and validating), error messages are displayed only in the default language, the default language is en. I tried to send data from the form without the help of ajax, everything works well, messages are displayed in both Russian and English.
reoutes/web.php
Route::group(['prefix' => LaravelLocalization::setLocale()], function(){
Route::get('/', 'PagesController#getProfile')->name('profile');
Route::get('/skills', 'PagesController#getSkills')->name('skills');
Route::get('/portfolio', 'PagesController#getPortfolio')->name('portfolio');
Route::get('/resume', 'PagesController#getResume')->name('resume');
Route::post('/contact', 'PagesController#contact');
});
controller
public function contact(Request $request){
$validator = Validator::make($request->all(), [
'name' => 'required',
'email' => 'required|email',
'message' => 'required'
]);
if ($validator->passes()) {
Mail::to('mycontactform#mail.ru')->send(new Contact($request));
return response()->json(['success'=>'Message sent successfully!']);
}
return response()->json(['error'=>$validator->errors()->all()]);
}
js
$(document).ready(function() {
$(".btn-send-message").click(function(e){
e.preventDefault();
$.ajax({
url: "/contact",
type:'POST',
data: $('#contact-form').serialize(),
beforeSend: function() {
$("#loading").show();
$(".fa-paper-plane").hide();
},
complete: function() {
$("#loading").hide();
$(".fa-paper-plane").show();
},
success: function(data) {
if($.isEmptyObject(data.error)){
printSuccessMsg();
}else{
printErrorMsg(data.error);
}
}
});
});
var $success_msg = $(".print-success-msg");
var $error_msg = $(".print-error-msg");
function printSuccessMsg() {
$success_msg.html('Message sent successfully!');
$success_msg.css('display','block');
$success_msg.delay(5000).fadeOut(350);
$('#contact-form')[0].reset();
}
function printErrorMsg (msg) {
$error_msg.find("ul").html('');
$error_msg.css('display','block');
$.each( msg, function( key, value ) {
$error_msg.find("ul").append('<li>'+value+'</li>');
});
$error_msg.delay(5000).fadeOut(350);
}
});
form
<div class="modal-body col-md-8 offset-md-2">
<div class="alert alert-danger print-error-msg" style="display:none">
<strong>Errors:</strong>

Answer 1

Use LaravelLocalization::getLocalizedURL() which returns an URL adapted to $locale.
So your ajax code will be.
$.ajax({
url: "{{ LaravelLocalization::getLocalizedURL(LaravelLocalization::getCurrentLocale(),'/contact') }}",
type:'POST',
data: $('#contact-form').serialize(),
beforeSend: function() {
$("#loading").show();
$(".fa-paper-plane").hide();
},
complete: function() {
$("#loading").hide();
$(".fa-paper-plane").show();
},
success: function(data) {
if($.isEmptyObject(data.error)){
printSuccessMsg();
}else{
printErrorMsg(data.error);
}
}
});

Answer 2

When you return your response try to use this helper __('translated_string')
To use this helper, you have to create some translate.php file in those folders resources/lang/en and resources/lang/en
For example:
File resources/lang/en/translate.php should contain this array
return [
'success_message' => 'Message sent successfully!',
];
File:
resources/lang/ru/translate.php should contain this array
return [
'success_message' => 'Сообщение успешно отправлено!',
];
For example:
return response()->json(['success'=> __('translate.success_message') ]);
To get some translated string, use dot notation for this helper;
