Question

public function update($id)
{
$input = Input::all();
$validation = Validator::make($input, User::$rules);
if ($validation->passes())
{
$user = User::find($id);
$user->update($input);
return Redirect::route('users.show', $id);
}
return Redirect::route('users.edit', $id)
->withInput()
->withErrors($validation)
->with('message', 'There were validation errors.');
}
this is what the code i am having, when I attempt to update a record it shows the following error message. Access to undeclared static property: User::$rules
the user model as follows
<?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');
}

I imagine you have a property in your User model like this:
<?php
class User extends Eloquent {
public $rules = array(
'email' => 'required|email|unique:users',
'password' => 'required|min:8',
);
}
This is a class instance property, but you’re trying to access it statically (the error messages tells you such).
Simply add the static keyword to the property:
<?php
class User extends Eloquent {
public static $rules = array(
'email' => 'required|email|unique:users',
'password' => 'required|min:8',
);
}
