Laravel: Why are validation messages not show? - laravel

Question

I use Laravel 5.4 on hosting. My validation method is working, but it doesn't show messages. I do all the needed operations for displaying errors but it doesn't work.
#if($errors->has('recipient'))
<div class="form-group">
<label class="col-lg-2 control-label"></label>
<div class="col-lg-10">
<div class="alert alert-danger">
<ul>
#foreach ($errors->get('recipient') as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
</div>
</div>
#endif
I use {{ csrf_field() }} tokens. Validation rules work if wrong user types are used, but messages are not displayed.
My send method:
public function send(Request $request)
{
$this->validator($request->all())->validate();
$this->create($request->all());
return redirect($this->redirectToAfterSendMessage);
}
My validator code:
protected function validator(array $data)
{
return Validator::make($data, [
"$this->recipient" => [
'sometimes',
'required',
'email',
'exists:users,email',
Rule::notIn([auth()->user()->email])
],
"$this->subject" => 'sometimes|required|min:10',
"$this->message" => 'sometimes|required|min:50',
], $this->validator_messages());
}
My routes:
Route::get('/compose', 'InboxController#compose') ->name('compose');
Route::post('/compose', 'InboxController#send');
Result of dump($errors):
ViewErrorBag {#244 ▼
#bags: []
}

EDITED
To fix your current problem, change $errors->get('recipient') to $errors->all().
It should look like this:
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach

This isn't a direct solution for your question. However an even better approach (imo) than yours are custom requests. You can quickly generate custom requests by using the following command:
php artisan make:request CustomRequest
After that you can change type from Request to CustomRequest
public function send(CustomRequest $request)
{
$this->create($request->all());
return redirect($this->redirectToAfterSendMessage);
}
And in CustomRequest.php your extract your validation logic like so:
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class CustomRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'name' => 'required',
'email' => 'required',
'message' => 'required',
];
}
public function messages()
{
return [
'name.required' => 'Name is required.',
'email.required' => 'Email is required.',
'message.required' => 'Message is required.',
];
}
}
Hope this helps.

You need to change:
"$this->recipient"
"$this->subject"
"$this->message"
To:
'recipient'
'subject'
'message'
