I'm trying to access the messages from the validator in the controller using the following code.
$valid = Validator::make($input,$rules);
print_r($valid->messages());
However, I'm not getting any output even though the validation is failing.
What do I need to do to get the Laravel-generated validation messages?
You need to run $validator->fails() or $validator->passes() before checking for the messages:
$valid = Validator::make($input,$rules);
$validator->fails();
print_r($valid->messages());
But assuming you know that, well, you could be using messages()->all(), but the way you're are doing should work. Try this (standalone-ish) code in your end:
$validator = Validator::make(
array('name' => 'Dayle'),
array('name' => 'required|min:15')
);
if ($validator->fails())
{
// The given data did not pass validation
}
print_r($validator->messages()->all());
If it works then the problem is realated to your $input and/or $rules.

So i'm working on validating a form's inputs using the following code:
$request->validate([
'title' => 'bail|required|max:255',
'body' => 'required',
]);
So basically, there are two fields in the form, a title and a body and they have the above rules. Now if the validation fails I want to catch the error directly in the controller and before being redirected to the view so that I can send the error message as a response for the Post request. What would be the best way to do it?
I understand that errors are pushed to the session but that's for the view to deal with, but i want to deal with such errors in the controller itself.
Thanks
If you have a look at the official documentation you will see that you can handle the input validation in different ways.
In your case, the best solution is to create the validator manually so you can set your own logic inside the controller.
If you do not want to use the validate method on the request, you may create a validator instance manually using the Validator facade.
Here a little example:
public function store(Request $request)
{
$validator = Validator::make($request->all(), [
'title' => 'bail|required|max:255',
'body' => 'required',
]);
// Check validation failure
if ($validator->fails()) {
// [...]
}
// Check validation success
if ($validator->passes()) {
// [...]
}
// Retrieve errors message bag
$errors = $validator->errors();
}
For someone who wants to know how to get validation errors after page redirection in the controller:
$errors = session()->get('errors');
if ($errors) {
//Check and get the first error of the field "title"
if ($errors->has('title')) {
$titleError = $errors->first('title');
}
//Check and get the first error of the field "body"
if ($errors->has('body')) {
$bodyError = $errors->first('body');
}
}
$errors will contain an instance of Illuminate/Contracts/Support/MessageBag
You can read more on the API here: https://laravel.com/api/8.x/Illuminate/Contracts/Support/MessageBag.html
Note: I have tested it in Laravel 8, it should work on Laravel 6+ if you get the MessageBag from the session
As the question states. I am using the validation method where the Rules and Custom Messages are placed in the Http/Requests folder. However, I want to get the messageErrorBag in Laravel I don't have any problems if I am using the code below I can easily add my own variables to be passed together with the validator message bag.
$validatedData = $request->validate([
'title' => 'required|unique:posts|max:255',
'body' => 'required',
]);
However, if using the code below. I cannot do it since Laravel already handles the error return as per documentation.
public function store(StoreBlogPost $request)
{
// The incoming request is valid...
// Retrieve the validated input data...
$validated = $request->validated();
}
My question how can I do it? before it redirects back with the error message bag.? Is it possible
If you use StoreBlogPost in Controller , it automatically returns messages but if you want your messages in body of controller you should add validator to your controller body and use this code:
if ($validator->fails())
{
foreach ($validator->messages()->getMessages() as $field_name => $messages)
{
var_dump($messages); // messages are retrieved (publicly)
}
}
hope it helps
Hi guys I'm working on API but I need to validate some data at backend, in this case, we only need a postman to send parameters and headers.
All is working fine now but I need more useful data in each request, Laravel has by default a Validator Form Request Validation, but I don´t know how to use at API side.
I need to send the error message in JSON to Postman.
I found two options, one, make validations into a controller but seems to much code and the other make a php artisan make:request StoreObjectPost and then import the request into the controller and change the request of the store method, which one do you recommend, Ty!
You could instantiate the validator yourself like this:
$validator = Validator::make($request->all(), [
'name' => 'min:5'
]);
// then, if it fails, return the error messages in JSON format
if ($validator->fails()) {
return response()->json($validator->messages(), 200);
}
$PostData = Input::all();
$Validator = Validator::make(array(
'name' => $PostData['name']
), array(
'name' => 'required'
));
if ($Validator->fails()) { //if validator is failed
return false;
} else {
// do some thing here
}
Hope this may help you
You should override response(array $errors) method of FormRequest.
public function response(array $errors)
{
//Format your error message
if ($this->expectsJson()) {
return new JsonResponse($errors, 422);
}
return $this->redirector->to($this->getRedirectUrl())
->withInput($this->except($this->dontFlash))
->withErrors($errors, $this->errorBag);
}
I prefer the second option. We will be able to keep our controller clean that way, even when we use many validations for the data or using custom error message in the validation
I was testing this new framework (Laravel) and upto now i'm following those examples which they have put in their documentation. All is going good till i got this problem.
i am calling Redirect::to('\signup')->withErrors($validator->messages()); but its not showing anything
but if i just print it like print_r($validator->messages()); it shows me the errors. Please help me and tell me where i am going wrong?
Controller
public function registerUser(){
$validator = Validator::make(Input::all(),array(
'username' => 'required|email|unique:user',
'password' => 'required|min:8',
'fullname' => 'required'
)
);
if($validator->fails()){
return Redirect::to('signup')->withInput()->withErrors($validator);
}else{
return Redirect::route('user');
}
}
Route
Route::get('/signup',array('as'=>'signup', 'uses'=>'HomeController#signUp'));
View
<?php print_r($errors) ; ?>
Here's the relevant information from the Laravel website:
Route::post('register', function()
{
$rules = array(...);
$validator = Validator::make(Input::all(), $rules);
if ($validator->fails())
{
return Redirect::to('register')->withErrors($validator);
}
});
Which you can reference from Blade like this...
<?php echo $errors->first('email'); ?>
Notice how $errors is an object? You call print_r($errors) which may not produce very useful output.
Try this...
<?php
var_dump($errors->first('username'));
var_dump($errors->first('password'));
var_dump($errors->first('email'));
?>
Also: Your unique:user validation should probably be unique:user,username. Use the database table name and column name, not the model values.
Note: If you are testing this in a browser, you may want to look into using Clockwork, which allows you to see Session information from the browser without the print_r/var_dump calls.
The problem was that I changed the secure option to true in session file (in config folder) and was testing it on local server without https. That is why my errors were not showing in view.
I'm trying to create a custom validation rule within laravel 4 and am struggling to get it to work or understand what I'm doing.
Currently - when I try to submit a form and validate it i get the following in my browser:
/**/
Which I'm taking as something is broken!
I have created a class in app/validators/customValidate.php
class CustomValidate extends Illuminate\Validation\Validator
{
public function uniqueMailchimp($attribute, $value, $parameters)
{
$mailchimp = MailchimpWrapper::lists()
->memberInfo(
'xxxxxxx',
array('emails'=>array(
'email'=>$value
)
));
//dd($$mailchimp['success_count']);
return ($mailchimp['success_count'] > 0 ? false : true );
}
I have run composer dump-autload
In my controller I am doing the following:
$rules = array(
'email' =>'email|uniqueMailchimp',
);
$messages = array(
'uniqueMailchimp'=>'The email provided has already been used.'
);
$validator = Validator::make($data, $rules, $messages);
}
I am then checking for a valid form with:
if($validator->passes()) {
# code
}
if validation fails the controller should redirect to the view:
return Redirect::route('members.create')
->withInput()
->withErrors($validator)
->with('errMessage', $message);
I've probably missed a step. I've seen posts about registering the rule in global.php but I'm not sure what I'm doing.
Any help appreciated
You are quite right - you need to register your rule with the validator. In any bootstrap-like file (a service provider is the best candidate if you have one, else app/start/global.php is good, and routes.php wouldn't be crazy either) you need the following code:
Validator::extend('foo', 'CustomValidate#uniqueMailchimp');
However, if you take a look at the docs you'll see that you don't need a whole class for this - you can just do it as a closure. A class is useful if you want the automatic IoC DI carried out for you though (although you don't appear to use that in your validator).
