Declaration

<?php

namespace app\models\enums;

use yii2mod\enum\helpers\BaseEnum;

class PostStatus extends BaseEnum
{
    const PENDING = 0;
    const APPROVED = 1;
    const REJECTED = 2;
    const POSTPONED = 3;
    
    /**
     * @var string message category
     * You can set your own message category for translate the values in the $list property
     * Values in the $list property will be automatically translated in the function `listData()`
     */
    public static $messageCategory = 'app';
    
    /**
     * @var array
     */
    public static $list = [
        self::PENDING => 'Pending',
        self::APPROVED => 'Approved',
        self::REJECTED => 'Rejected',
        self::POSTPONED => 'Postponed',
    ];
}

Enum creation

$status = new PostStatus(PostStatus::PENDING);

// or you can use the magic methods

$status = PostStatus::PENDING();

Static methods

PostStatus::getConstantsByValue() // ['PENDING', 'APPROVED', 'REJECTED', 'POSTPONED']
PostStatus::getConstantsByName() // ['PENDING' => 0, 'APPROVED' => 1, 'REJECTED' => 2, 'POSTPONED' => 3]
PostStatus::isValidName(1) // false
PostStatus::isValidName('APPROVED') // true
PostStatus::isValidValue(1) // true
PostStatus::isValidValue('Approved') // false
PostStatus::listData() // ['Pending', 'Approved', 'Rejected', 'Postponed']
PostStatus::getLabel(1) // Approved
PostStatus::getValueByName('Approved') // 1

Type-Hint and Validation Rules

<?php

use models\enums\PostStatus;
use yii\db\ActiveRecord;

class CommentModel extends ActiveRecord
{
    public function rules()
    {
        return [
            ['status', 'default', 'value' => PostStatus::APPROVED],
            ['status', 'in', 'range' => PostStatus::getConstantsByName()],
        ];
    }

    public function setStatus(PostStatus $status)
    {
        $this->status = $status->getValue();
    }

    public function getStatus()
    {
        return $this->status;
    }
}
