I'm trying to retrieve errors when a user fills a form submitted using ajax. I'm following this tutorial. I'm not getting the result expected despite the logic I think should be right. Here is my blade view code :
@extends('layouts.layout')
@section('title','Soumettre thématique')
@section('content')
<body>
<div class="container_fluid">
<div class="row">
<div class="alert alert-danger print-error-msg" style="display: none;">
@if($errors->any())
<ol style="color: red">
@foreach($errors->all() as $error)
<li>
{{$error}}
</li>
@endforeach
</ol>
@endif
</div>
</div>
</div>
<form method="POST" action=" {{route('themes.store')}} ">
@csrf
<!-- Intitulé du thème -->
<input type="text" name="intitule" id="intitule" placeholder="Intitulé du thème" required><br>
<!-- Catégorie -->
<select name="categorie" required>
<option value="">-- Catégorie --</option>
<option value="web">Développement web</option>
<option value="appMobile">Programmation application mobile</option>
<option value="secure">Sécurisation</option>
<option value="other">Autre</option>
</select> <br>
<!-- Filière désirée -->
<input type="checkbox" name="filiere[]" id="GL" value="GL" required>
<label for="GL">Génie Logiciel</label><br>
<input type="checkbox" name="filiere[]" id="SI" value="SI" required>
<label for="SI">Sécurité Informatique</label><br>
<input type="checkbox" name="filiere[]" id="IM" value="IM" required>

<input type="checkbox" name="filiere[]" id="SIRI" value="SIRI" required>
<label for="SIRI">Systèmes d'Information et Réseaux Informatiques</label><br>
<!-- Descriptif -->

<input type="submit" name="submit" id="submit" value="Ajouter">

The controller store function :
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$validator = Validator::make($request->all(),[
'intitule' => 'unique:themes,intitule'
]);
$theme = new Theme;
$theme->intitule = $request->input('intitule');
$theme->description = $request->input('description');
$theme->categorie = $request->input('categorie');
$request->merge([
'filiere' => implode(',', (array) $request->get('filiere'))
]);
$theme->filiereDesiree = $request->input('filiere');
$theme->save();
if ($validator->passes()) {
return response()->json(['success'=>'Added new records.']);
}
return response()->json(['error'=>$validator->errors()->all()]);
}
The problem is I'm not getting a message at all, either success or error may it be. I don't know where I'm doing wrong there.
P.S: I've already used Ajax to submit this form. I did it using XMLHttpRequest object. The problem was I do not know how to use the 422 status to return errors using this XHR object. I've looked for it but found nothing really helpful.. So I changed this method to use here the ajax() jquery function which seems to be more used. Still not getting the messages.. It's the first time I try to manage the validation errors using Ajax. Your help would be very welcome
