Laravel custom password validation - php

Question

Hi gladly I want to use a custom validation rule for my textfield:
{{Form::label('password', 'Wachtwoord: ', array('class' => 'col-xs-4'))}}
<div class="col-xs-2">{{ Form::password('password', array('class' => 'form-control', 'placeholder'=>'Password')) }}</div>
And I already had followed the instructions on the following link: http://laravel.com/docs/4.2/validation#custom-validation-rules
But I get stuck when I want to use my custom validation.. I think that I have done something wrong in my code.
Gladly I would like to use the validatePassword() method (in validation.php) for my password textfield.
Here is my UserController.php:
public function update($id)
{
$user_old_data = User::find($id);
$input_password = Input::get('password');
Validator::resolver(function($translator, $data, $rules, $messages)
{
return new validation($translator, $data, $rules, $messages);
});
/*Validator::extend('validatePassword', function($input_passwords,$input_passwords){
});*/
/*$validator = Validator::make($data = $thisUser, User::$rules);
if ($validator->passes()) {
if($user_old_data['email'] != $new_email){
$email_exists = User::FindEmailOrFail2(Input::get('email') );
if($email_exists)
return Redirect::back()->withErrors($validator)->withInput();
}
//maak message variabel aan in je user index view.
return Redirect::to('user/users')->with('message', 'Update with new password succesfull');
} */
return Redirect::back()->withErrors($validator)->withInput();
}
Here is my validation.php:
<?php
// app/validators/validation.php
class validation extends Illuminate\Validation\Validator
{
public function validateFoo($attribute, $value, $parameters){
//return $value == 'foo';
echo "this is the: " . $value;
}
//{4,} will match strings of length 4 or more.
protected function validatePassword( $attribute, $value ) {
return (bool) preg_match('/^[a-z]{4,}+$/', $value);
die('test');
}
}

If your code reflects the scope of your project you may not need a custom validator at all. You can use pattern:/^[a-z]{4,}$/ as one of your $rules in your User model.
You can see examples in Laravel's documentation: http://laravel.com/docs/4.2/validation#basic-usage
The pattern you used : /^[a-z]{4,}+$/ can be interpreted as "a string beginning with at least 4 characters matching lowercase a through z and a plus sign at the end of the string". Removing the plus sign (which regex is interpreting literally because of the quantifier before it) should make this work properly.
Remember to artisan optimize after you make changes to make sure the compiled.php is recompiled.
