Laravel 5.5更新帖子不起作用

edit.blade.php:

{!! Form::model($post, array('method'=>'PATCH','url'=>'/posts/{post}'.$post->id))  !!}

{{ method_field('PATCH') }}

{{csrf_field()}}

Route::get('/', 'PostsController@index')->name('home');
Route::get('/posts/create', 'PostsController@create');
Route::post('/posts', 'PostsController@store');
Route::get('/posts/{post}', 'PostsController@show');
Route::get('/posts/tags/{tag}', 'TagsController@index');
Route::post('/posts/{post}/comments','CommentsController@store');
Route::get('/posts/{id}/edit', 'PostsController@edit');
Route::get('/edit/{post}', 'PostsController@update');
Route::patch('/post/{post}', 'PostsController@update');
Route::get('/register', 'RegistrationController@create');
Route::post('/register', 'RegistrationController@store');
Route::get('/login', 'SessionsController@create');
Route::post('/login', 'SessionsController@store');
Route::get('/logout', 'SessionsController@destroy');

Post::where('id', $post)->update($request->all());

Post::where('id', $post->id)->update($request->all());

后置控制器：

public function edit( Post $post )
{
    return view('posts.edit', compact('post'));
}


public function update(Request $request, Post $post)
{
    Post::where('id', $post)->update($request->all());

    return redirect('/home');
}

您正在此处使用，请将其更改为：

public function update(Request $request, Post $post){
    $post->update($request->all());
    return redirect('/home');
}

另外，将URL更改为：

'url' => '/posts/' . $post->id

另外，请删除这些字段，因为

{！！Form:：model（）！！}

会自动为您插入这些字段：

{{ method_field('PATCH') }}
{{ csrf_field() }}

---

更改：

{!! Form::model($post, array('method'=>'PATCH','url'=>'/posts/{post}'.$post->id))  !!}

{{ method_field('PATCH') }}

{{csrf_field()}}

Route::get('/', 'PostsController@index')->name('home');
Route::get('/posts/create', 'PostsController@create');
Route::post('/posts', 'PostsController@store');
Route::get('/posts/{post}', 'PostsController@show');
Route::get('/posts/tags/{tag}', 'TagsController@index');
Route::post('/posts/{post}/comments','CommentsController@store');
Route::get('/posts/{id}/edit', 'PostsController@edit');
Route::get('/edit/{post}', 'PostsController@update');
Route::patch('/post/{post}', 'PostsController@update');
Route::get('/register', 'RegistrationController@create');
Route::post('/register', 'RegistrationController@store');
Route::get('/login', 'SessionsController@create');
Route::post('/login', 'SessionsController@store');
Route::get('/logout', 'SessionsController@destroy');

Post::where('id', $post)->update($request->all());

Post::where('id', $post->id)->update($request->all());

至：

{!! Form::model($post, array('method'=>'PATCH','url'=>'/posts/{post}'.$post->id))  !!}

{{ method_field('PATCH') }}

{{csrf_field()}}

Route::get('/', 'PostsController@index')->name('home');
Route::get('/posts/create', 'PostsController@create');
Route::post('/posts', 'PostsController@store');
Route::get('/posts/{post}', 'PostsController@show');
Route::get('/posts/tags/{tag}', 'TagsController@index');
Route::post('/posts/{post}/comments','CommentsController@store');
Route::get('/posts/{id}/edit', 'PostsController@edit');
Route::get('/edit/{post}', 'PostsController@update');
Route::patch('/post/{post}', 'PostsController@update');
Route::get('/register', 'RegistrationController@create');
Route::post('/register', 'RegistrationController@store');
Route::get('/login', 'SessionsController@create');
Route::post('/login', 'SessionsController@store');
Route::get('/logout', 'SessionsController@destroy');

Post::where('id', $post)->update($request->all());

Post::where('id', $post->id)->update($request->all());

---

新路线：

{!! Form::model($post, array('method'=>'PATCH','url'=>'/posts/{post}'.$post->id))  !!}

{{ method_field('PATCH') }}

{{csrf_field()}}

Route::get('/', 'PostsController@index')->name('home');
Route::get('/posts/create', 'PostsController@create');
Route::post('/posts', 'PostsController@store');
Route::get('/posts/{post}', 'PostsController@show');
Route::get('/posts/tags/{tag}', 'TagsController@index');
Route::post('/posts/{post}/comments','CommentsController@store');
Route::get('/posts/{id}/edit', 'PostsController@edit');
Route::get('/edit/{post}', 'PostsController@update');
Route::patch('/post/{post}', 'PostsController@update');
Route::get('/register', 'RegistrationController@create');
Route::post('/register', 'RegistrationController@store');
Route::get('/login', 'SessionsController@create');
Route::post('/login', 'SessionsController@store');
Route::get('/logout', 'SessionsController@destroy');

Post::where('id', $post)->update($request->all());

Post::where('id', $post->id)->update($request->all());

路由：：patch（'/posts/{id}/edit/{post}'，'UpdateController@update');

{！！Form:：model（$post，array（'method'=>'post'，'url'=>'/posts/{id}/edit'.$post->id））

我认为/posts/{id}/edit不起作用了

好了，现在可以了。。但是不要更新帖子，只要创建一个新的post@Matteo你还没问过这件事。如果您还想创建一个新的帖子（如果它还不存在），请使用其他方法或

updateOrCreate（）

方法。我已经创建了一个帖子，我只想能够重新编辑和更新一个帖子post@Matteo但它无法创建新的帖子。如果您使用的是如我所示的

update（）

方法和

PostsController@update

方法已执行。我知道，但它会创建一个新帖子
