Unset child object static variable from abstract parent class php

Question

I am using Laravel and it's Validators.

I have the following code in my controller:

class ResellerController extends BaseController{

    public function add() {

        //some code before

        $userValidator =  new App\Services\Validators\UserCreateValidator();
        //HERE I WANT TO REMOVE THE company KEY FROM THE RULES IN THE USERS CREATE VALIDATOR
        $userValidator->removeRule('company');      

        //code execution continues      
    }
}

The UserCreateValidator extends a parent Validator class:

namespace App\Services\Validators;

class UserCreateValidator extends Validator {

    public static $rules = array(
        'firstName' => 'required',
        'lastName' => 'required',
        'email' => 'required|email|unique:users',
        'company' => 'required'
    );  
}

And here is the base Validator class:

namespace App\Services\Validators;

abstract class Validator {

    /**
     * Validation rules
     * @var array
     */
    public static $rules;

    //THIS CODE DOES NOT WORK IN THE CONTROLLER UP
    public static function removeRule($ruleKey){

        if(is_array($ruleKey))
        {
            foreach($ruleKey as $key)
            {
                if(!array_key_exists($key, static::$rules)) continue;

                unset(static::$rules[$key]);
            }

            return true;
        }

        if(!array_key_exists($ruleKey, static::$rules)) //return false;

        unset(static::$rules['company']);

        return true;
    }
}

The unsettting of the static::$rules[$key] in ResellerController does not work.

I can see in a XDEBUG session (after this line gets executed) that the static::$rules['company'] is still present in the UserCreateValidator as property.

I thought that Late Static Binding should solve this problem? What is wrong?

Answer 1

The problem is solved. It was in the commented part in the:

if(!array_key_exists($ruleKey, static::$rules)) //return false;

The unsetting is working fine after I uncomment the return false.

Silly mistake :)
