Laravel 5.2 Custom validation message with custom validation function

Question

I want to create custom validation rule with custom validation error message. For this I created a rule:

$rule => [
    'app_id' => 'isValidTag'
]

And for custom message:

$message => [
   app_id.isValidTag   => 'Not a Valid id'
];

After that I created Service Provider:

class CustomValidationServiceProvider extends ServiceProvider
{
    public function boot() {

    //parent::boot();

    $this->app->validator->resolver(function($transator,$data,$rules,$messages){
            return new CustomValidator($transator,$data,$rules,$messages);
        });
    }
}

And my Custom validation class is:

class CustomValidator extends Validator {
    if(empty($parameters)) {
        return true;
    }

    $conext = $parameters[0];
    $tag = Tag::where('id', $value)->where('context', $conext)->get();

    $flag = false;
    if($tag->count() > 0) {
        $flag = true;
    }       

    return $flag;
}

All is working fine but the issue is my custom message for app_id.isValidTag is not working even all other message are working fine.

Please suggest me what I missing here or in Laravel 5.2 there is some change to display message. Any idea will be appreciated.

Here is a great tutorial for this: http://itsolutionstuff.com/post/laravel-5-create-custom-validation-rule-exampleexample.html

I think you did it Laravel 4.* way. This is how it is done in Laravel 5.2 in my example where i was making registration authorisation form so files like AuthController.php was premade:

AuthController.php

Validator::make($data, [
    ...
    // add your field for validation
    'name_of_the_field' => 'validation_tag', // validation tag from validation.php
    ...

CustomAuthProvider.php // if you didn't make a custom provider use Providers/AppServiceProvider.php

public function boot() {
    ...
    Validator::extend('validation_tag', function($attribute, $value, $parameters, $validator) {
            // handle here your validation
            if (  your_query ) {
                return true;
            }
            return false;
    });

validation.php

...
// add your validation tag and message to be displayed
'validation_tag'           => 'The field :attribute isn't good',
...

file.blade.php // to add at the end of the page all your errors add

@if (count($errors) > 0)
      <div class="alert alert-danger">
             <ul>
                   @foreach ($errors->all() as $error)
                         <li>{{ $error }}</li>
                   @endforeach
             </ul>
       </div>
@endif

You can also add the error message directly in the function using $validator->setCustomMessage(['<attribute>.<rule name>' => '<error message>'])
