如何在 laravel 6 上上传图片？

Question

我试图在 laravel 6 上编辑图像，但它没有前进到下一个视图，停留在表单视图上。

我看过很多 laravel 5.8 和 6 的教程。我无法让它以任何方式工作

这是 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');

}

这是 Web.php 文件：

Route::get('/actualizar/{id}', 'crearNoticiaController@update')->name('actualizar');

Route::get('/editar/{id}', 'crearNoticiaController@edit')->name('editar');

这是表格文件：

<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>

Answer 1

我用这种方式解决了：在 web.php 我把补丁而不是得到Route::patch('/actualizar/{id}', 'crearNoticiaController@update')->name('actualizar');在我输入的编辑刀片中：@method('PATCH')这是控制器中的更新：&nbsp;public function update(Request $request, $id){&nbsp; &nbsp; $noticia = Noticia::findOrFail($id);&nbsp; &nbsp; $noticia->titulo = $request->get('titulo');&nbsp;&nbsp; &nbsp; $noticia->contenido = $request->get('contenido');&nbsp; &nbsp; $noticia->imagen = $request->file('imagen');&nbsp; &nbsp; $validator = $request->validate([&nbsp; &nbsp; &nbsp; &nbsp;'imagen' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:4096',&nbsp; &nbsp; ]);&nbsp; &nbsp; $imageName = time().'.'.request()->imagen->getClientOriginalExtension();&nbsp; &nbsp; request()->imagen->move(public_path('images'), $imageName);&nbsp; &nbsp; $noticia->imagen = $imageName;&nbsp; &nbsp; $noticia->update();&nbsp; &nbsp; return redirect('/mostrar'); //Redirigimos a la la vista para mostrar las noticias&nbsp;}

我遇到了同样的问题，但幸运的是我解决了这个问题。我在下面添加了我的解决方案，我认为这会帮助你解决这个问题&nbsp; &nbsp;public function updatePost(Request $request, $id)&nbsp; &nbsp;{&nbsp; &nbsp; $validatedData = $request->validate([&nbsp; &nbsp; &nbsp;

首先在您的项目控制台命令上运行：php artisan storage:link然后尝试此代码，如果返回任何错误消息，请告诉我 khow：$imagen = $request->file("imagen");$extension = $imagen->extension();$filename = time().".".$extension;$request->file('imagen')->storeAs("public/images", $filename);最后检查您的public/images文件夹中是否存在图像文件。
