Route::post('/editposts', array('uses'=>'PostController#Update'));
Controller :
public function Update($id)
{
$Posts = Posts::find($id);
$Posts->Title = 10;
$Posts->Content = 10;
$Posts->save();
//return Redirect()->back(); Input::get('Title')
}

#foreach($showpost as $showpost)
<h1>Edit Posts :</h1>
{{ Form::open(array('url'=>'editposts', 'method'=>'post')) }}
Title : {{ Form::text('Title', $showpost->Title) }} <br> Content : {{ Form::text('Content', $showpost->Content ) }} <br> {{ Form::submit('Update') }}
{{ Form::close() }}
#endforeach
but when I want to Update my data i receive an error :
http://localhost:8000/editposts/1
Missing argument 1 for App\Http\Controllers\PostController::Update()

Answer 1

You need to change route:
Route::post('editposts/{id}', 'PostController#Update');
Then the form to:
{{ Form::open(['url' => 'editposts/' . $showpost->id, 'method'=>'post']) }}

Answer 2

Change your post route to:
Route::post('/editposts/{id}', 'PostController#Update');
Done!

Answer 3

Correct the route,specify a parameter
Route::post('editposts/{id}', 'PostController#Update');
Pass the post'id as paramater
{{ Form::open(array('url'=>'editposts/'.$post->id, 'method'=>'post')) }}
Title : {{ Form::text('Title', $showpost->Title) }} <br> Content : {{ Form::text('Content', $showpost->Content ) }} <br> {{
Form::submit('Update') }}
{{ Form::close() }}
Notice $post->id

Answer 4

First declare your route:
Route::post('/editposts/{id}', array('uses'=>'PostController#Update'));
Then update your form url:
{{ Form::open(['url' => url()->action('PostController#Update', [ "id" => $showpost->id ]), 'method'=>'post']) }}
This is assuming your model's id column is id
(Optional) You can also use implicit model binding :
public function Update(Posts $id) {
//No need to find it Laravel will do that
$id->Title = 10;
$id->Content = 10;
$id->save();
}
