Extending Custom Validation-Class

问题:

I've been experimenting with Laravel 4 recently and am trying to get a custom validation-class to work.

Validation-Class

<?php

class CountdownEventValidator extends Validator {

    public function validateNotFalse($attribute, $value, $parameters) {
        return $value != false;
    }

    public function validateTimezone($attribute, $value, $parameters) {
        return !empty(Timezones::$timezones[$value]);
    }

}

My rules are setup like this:

protected $rules = [
    'title' => 'required',
    'timezone' => 'timezone',
    'date' => 'not_false',
    'utc_date' => 'not_false'
];

I call the Validator inside my model like this:

$validation = CountdownEventValidator::make($this->attributes, $this->rules);

I get the following error:

BadMethodCallException

Method [validateTimezone] does not exist.

I've looked up quite a few tutorials but I couldn't find out what's wrong with my code.

Thank you for your help

When you call Validator::make you're actually calling Illuminate\Validation\Factory::make although the method itself is non-static. When you hit the Validator class you're going through the facade and in the background the call looks something like this.

App::make('validator')->make($this->attributes, $this->rules);

It then returns an instance of Illuminate\Validation\Validator.

You can register your own rules with Validator::extend or you can register your own resolver. I recommend, for now, you just extend the validator with your own rules using Validator::extend.

Validator::extend('not_false', function($attribute, $value, $parameters)
{
    return $value != false;
});

You can read more on this and on how to register your own resolver over on the official documentation.

Is that function supposed to be static? What if you remove static?

public function validateTimezone($attribute, $value, $parameters) {
    return !empty(Timezones::$timezones[$value]);
}
