How I upload an image on laravel 6? - php

Question

im trying to edit an image on laravel 6, but but it does not advance to next view, stays on the form view.
I have seen many tutorials of laravel 5.8 and 6. I can't make it work in any way
This is de controller:
public function update(Request $request, $id)
{
$validator = $request->validate([
'titulo' => 'required | max:50', //campo obligatorio y máximo 50 caracteres
'contenido' => 'required | max:150',
'imagen' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:4096',
]);
$image_name = time().'.'.$request->imagen->getClientOriginalExtension();
$request->image->move(public_path('images'), $image_name);
$datos = array(
'titulo' => $request->titulo,
'contenido' => $request->contenido,
'imagen' => $image_name,
);
Noticia::whereId($id)->update($datos);
return redirect('/mostrar');
}
THis is Web.php file:
Route::get('/actualizar/{id}', 'crearNoticiaController#update')->name('actualizar');
Route::get('/editar/{id}', 'crearNoticiaController#edit')->name('editar');
this is form file:
<div class="subir-imagen">
<form method="get" action="{{ route('actualizar', $noticia->id) }}" enctype="multipart/form-data">
#csrf
<div class="crear-titulo">
<input class="titulo" type="text" name="titulo" placeholder="Escriba el titulo" value="{{$noticia->titulo}}">
</div>
<div class="crear-contenido">
<textarea class="ckeditor" name="contenido" placeholder="Escriba el contenido" >
{{$noticia->contenido}}
</textarea>
</div>
<table border="2">
<tr>
<td><img src="{{URL::to('/')}}/images/{{$noticia->imagen}}" alt="imagen" width="250" align="left"/></td>
</tr>
</table>
<div class="form-group">
<div class="col-md-6">
<input type="file" class="form-control" name="imagen" />
</div>
</div>
<div class="form-group">
<div class="col-md-6 col-md-offset-4">
<input type="submit" class="btn btn-primary" value="Enviar" id="btn-enviar" />
</div>
</div>
</form>
</div>

First run on your project console command:
php artisan storage:link
Then try this code and if return any error message tell me khow:
$imagen = $request->file("imagen");
$extension = $imagen->extension();
$filename = time().".".$extension;
$request->file('imagen')->storeAs("public/images", $filename);
Finally check your public/images folder for image file exists.
Also you can read about storing uploaded files in laravel 6.x official documentation

I've solved with this way:
In web.php I put patch instead get
Route::patch('/actualizar/{id}', 'crearNoticiaController#update')->name('actualizar');
In the edit blade I put: #method('PATCH')
And this is the update in the controller:
public function update(Request $request, $id)
{
$noticia = Noticia::findOrFail($id);
$noticia->titulo = $request->get('titulo');
$noticia->contenido = $request->get('contenido');
$noticia->imagen = $request->file('imagen');
$validator = $request->validate([
'imagen' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:4096',
]);
$imageName = time().'.'.request()->imagen->getClientOriginalExtension();
request()->imagen->move(public_path('images'), $imageName);
$noticia->imagen = $imageName;
$noticia->update();
return redirect('/mostrar'); //Redirigimos a la la vista para mostrar las noticias
}
