使用Laravel提交表格

I am creating an edit page for my posts. I would prefer to create an html form instead of using FORM:: so I can really learn. I am having an issue when I try to submit the data to the right controller method.

The tutorial I am using says to use

{!! Form::open(['action' => ['PostsController@update', $post->id], 'method' => 'POST'])!!}

Using my limited knowledge I tried to recreate this as

<form action="{!! Route::post('/posts', ['PostsController@update', $post->id]) !!}" method="POST">

underneath both I am using <input name="_method" type="hidden" value="PUT">

The error I get is `"

Object of class Illuminate\Routing\Route could not be converted to string (View: /Users/Chris/code/chris/resources/views/posts/edit.blade.php)

My web.php file has Route::resource('posts', 'PostsController'); which as worked for everything else until now. In my contoller, my update method has

public function update(Request $request, $id)
{
     $this->validate($request, [
        'title' => 'required',
        'body' => 'required'
    ]);
    // Create Post
    $post = Post::find($id);
    $post->title = $request->input('title');
    $post->body = $request->input('body');
    $post->save();

    return redirect('/')->with('success', 'Post Updated');
}

What would the correct action be to submit an update for my info?

Thanks so much in advance!

replace the form action with the following: there are many solutions:

1- by using action method :

 <form action=" {!! action('PostsController@update',$post->id) !!}" method="POST">

2- by naming the route

<form action=" {!! route('route-name',$post->id) !!}" method="POST">

3- by using url method

<form action=" {!! url('/posts',$post->id) !!}" method="POST">

As Lagbox pointed out in the comments:

Route::post('/posts', ['PostsController@update', $post->id]) 

Is for defining the route in your routes file. To get the url you can do one of the following:

Hard code the uri

action="/posts/{{ $post->id }}"

Use the url() helper

action="{{ url("posts/$post->id") }}" or action="{{ url("post", $post->id) }}"

Use the route() helper (This will only work if you have given the route a name)

action="{{ route('the-route-name', $post->id) }}"

Use the action helper

action="{{ action('PostsController@update', $post->id) }}"

Here is a link to the various url helpers. My main advice here would be to mainly stick to just using one of them for a project.

Furthermore, your code should work absolutely fine the way it is for now but usually with REST (or the way Laravel uses rest) you would make either a PUT or PATCH request for updating instead of a POST request. However, standard html forms only support GET and POST so Laravel provides a way for you to spoof the form method:

<input type="hidden" name="_method" value="PUT" />

Thank you so much Lagbox. I used

<form action=" {!! route('route-name',$post->id) !!}" method="POST">

and it worked perfectly!
