我試圖在 laravel 6 上編輯圖像，但它沒有前進到下一個視圖，停留在表單視圖上。我看過很多 laravel 5.8 和 6 的教程。我無法讓它以任何方式工作這是 de 控制器： 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');}這是 Web.php 文件：Route::get('/actualizar/{id}', 'crearNoticiaController@update')->name('actualizar');Route::get('/editar/{id}', 'crearNoticiaController@edit')->name('editar');這是表格文件：<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>

我用這種方式解決了：
在 web.php 我把補丁而不是得到
Route::patch('/actualizar/{id}', 'crearNoticiaController@update')->name('actualizar');
在我輸入的編輯刀片中：@method('PATCH')
這是控制器中的更新：
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
}

我遇到了同樣的問題，但幸運的是我解決了這個問題。我在下面添加了我的解決方案，我認(rèn)為這會幫助你解決這個問題
public function updatePost(Request $request, $id)
{
$validatedData = $request->validate([
'title' => 'required|unique:posts|max:25|min:4',
'image' => 'mimes:jpeg,jpg,png,JPEG,JPG,PNG | max:100000',
]);
$data = array();
$data['category_id'] = $request->category_id;
$data['title'] = $request->title;
$data['details'] = $request->details;
$image = $request->file('image');
if($image)
{
$image_name = hexdec(uniqid());
$ext = strtolower($image->getClientOriginalExtension());
$image_full_name = $image_name.'.'.$ext;
$upload_path = 'public/assets/img/';
$image_url = $upload_path.$image_full_name;
$success = $image->move($upload_path,$image_full_name);
$data['image'] = $image_url;
unlink($request->old_photo);
$posts = DB::table('posts')->where('posts.id', $id)->update($data);
if($posts)
{
return Redirect()->route('all.posts')->with('success','Posts are inserted successfully');
}
else
{
return back()->with('error', 'Posts are not inserted successfully');
}
}
else
{
$data['image'] = $request->old_photo;
$posts = DB::table('posts')->where('posts.id', $id)->update($data);
if($posts)
{
return Redirect()->route('all.posts')->with('success','Posts are inserted successfully');
}
else
{
return back()->with('error', 'Posts are not inserted successfully');
}
}
}

首先在您的項目控制臺命令上運行：
php artisan storage:link
然后嘗試此代碼，如果返回任何錯誤消息，請告訴我 khow：
$imagen = $request->file("imagen");
$extension = $imagen->extension();
$filename = time().".".$extension;
$request->file('imagen')->storeAs("public/images", $filename);
最后檢查您的public/images文件夾中是否存在圖像文件。
