Here my best solution for manage :
- Store and Update submission in same form
- Load form with DB data on first load
- Load form with request data for nexts loads (with errors)
form.blade.php :
<!-- Display errors -->
@if ($errors->any())
<div class="alert alert-danger">
<ul style="margin:0">
@foreach ($errors->all() as $error)
<li></li>
@endforeach
</ul>
</div>
@endif
<!-- Store/Update Form -->
<form method="post" action="">
@if($post->id) @method('put') @endif
@csrf
<!-- Input -->
<div class="form-group">
<label>Titre</label>
<input type="text" name="title" class="form-control @error('title') is-invalid @enderror" value="" >
</div>
<!-- Textarea -->
<div class="form-group">
<label>Contenu</label>
<textarea name="content" rows="6" class="form-control @error('content') is-invalid @enderror">{!! count(old()) === 0 ? $post->content : old('content') !!}</textarea>
</div>
<!-- Checkbox -->
<div class="form-group">
<label>
<input type="hidden" name="online" value="0">
<input type="checkbox" name="online" value="1" class="@error('online') is-invalid @enderror" >
En ligne ?
</label>
</div>
<!-- Select (single value) -->
<div class="form-group">
<label>Catégorie</label>
<select name="category_id" class="form-control @error('category_id') is-invalid @enderror">
<option value=""></option>
@foreach($categories as $category)
<option value="" ></option>
@endforeach
</select>
</div>
<!-- Select (multiples values) -->
<div class="form-group">
<label>Tags</label>
<input type="hidden" name="tags" value="">
<select name="tags[]" class="form-control @error('tags') is-invalid @enderror" multiple="true">
@foreach($tags as $tag)
<option value="" ></option>
@endforeach
</select>
</div>
<button class="btn btn-primary" type="submit">Sauvegarder</button>
<a class="btn btn-light" href="">Annuler</a>
</form>

Routes.php :
<?php
// Welcome
Route::get('/', function () {
return view('app');
});
// Posts
Route::get('/posts', 'PostsController@index')->name('posts.index');
Route::get('/posts/create', 'PostsController@create')->name('posts.create');
Route::post('/posts/create', 'PostsController@store')->name('posts.store');
Route::get('/posts/{slug}/edit', 'PostsController@edit')->name('posts.edit');
Route::put('/posts/{slug}/edit', 'PostsController@update')->name('posts.update');
Consider the inputs "hidden" in the view who allow to resolve many problems on submissions. Consider too following methods :
- getTags()
- getCategory()
Until now it's the best solution I had find to simplify the view and the controller.
If someone had some bests practices, I'll be happy to read him.
Thanks everyone ;-)
