$user = User::find($id);
$user->update($input);

// can be joined on one line

$user = User::find($id)->update($input);

Other than that I don't see anything wrong. You can also use

$user = User::find(1);
$use->username = 'john';
$user->email = '[email protected]';
$user->save();

Did you set

['method' => 'PATCH']

on your form?

Yes I did use the ['method' => 'PATCH']. I tried the code you gave and I got a "Whoops, looks like something went wrong."

Here is my edit

@extends('users.scaffold')
@section('main')

<h1>Edit User</h1>

{{ Form::model($user, array('method' => 'PATCH', 'route' => array('users.update', $user->id))) }}

<ul>
	<li>
		{{ Form::label('username', 'Username:') }}
		{{ Form::text('username') }}
	</li>

	<li>
		{{ Form::label('password', 'Password:') }}
		{{ Form::text('password') }}
	</li>

	<li>
		{{ Form::label('email', 'Email:') }}
		{{ Form::text('email') }}
	</li>

	<li>
		{{ Form::label('phone', 'Phone:') }}
		{{ Form:: text('phone') }}
	</li>

	<li>
		{{ Form::label('name', 'Name:') }}
		{{ Form::text('name') }}
	</li>

	<li>
		{{ Form::submit('Update', array('class' => 'btn btn-info')) }}
		{{ link_to_route('users.show', 'Cancel', $user->id, array('class' => 'btn')) }}
	</li>
</ul>

{{ Form::close() }}

@if($errors->any())
	<ul>
		{{ implode('', $errors->all('<li class="error">:message</li>')) }}
	</ul>
@endif	

My model

<?php

use Illuminate\Auth\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;

class User extends Eloquent implements UserInterface, RemindableInterface {

	use UserTrait, RemindableTrait;

	/**
	 * The database table used by the model.
	 *
	 * @var string
	 */
	protected $table = 'users';

	/**
	 * The attributes excluded from the model's JSON form.
	 *
	 * @var array
	 */
	protected $hidden = array('password', 'remember_token');

	//ADDING A NEW USER

	protected $guarded = array('id');
	protected $fillable = array('username', 'password', 'email', 'phone', 'name', );

	public static $rules =array(
			'name' => 'required|min:5',
			'email' => 'required|email',
			'password' => 'required'
		);

	//EDITING A USER

	//$user = User::find($id);

	$user = User::find($id)->update($input);

}

Hi pogachar

I added that code to the controller and it worked. Thanks soo much. For some reason I must have misunderstood the tutorial I was busy going through.
