    </div>

</form>

Answer 1

The error is coming from your findOrFail() call. It is not finding a user with the id you're looking for.

This may be due to the order of the parameters in your update method. In the controller methods, the route parameters should be after the injected parameters. The documentation states "If your controller method is also expecting input from a route parameter, simply list your route arguments after your other dependencies." Try changing your update method to:

public function update(Request $request, $id) {
    //
}

Edit

Your POST route requires the user's id as a route parameter, but you have not supplied this when generating the URL for the <form> . The second parameter of the action() function takes an array of values to use as the route parameters. Your form statement should look like:

<form class="form-horizontal" role="form" method="POST" action="{{ action('Admin\UserController@update', ['id' => $user->id]) }}">

The documentation for the action() helper function can be found here .

Answer 2

Just pass a user id to your form like so:

<form class="form-horizontal" role="form" method="POST" action="{{action('Admin\UserController@update', $user->id) }}">

You can also use form builder and do it like so:

{!! Form::open(['method' => 'POST', 'action' => ['UserController@update', $user->id], 'class' => 'form-horizontal']) !!}

if the whole action part is confusing you can do it this other way:

<form class="form-horizontal" role="form" method="POST" action="{{url('user-edit/'.$user->id) }}">
