Behavior for language attributes for Yii2

Behavior LanguageAttributes is adding possibility to localize ActiveRecord model. It is finding a model field for application language.

E.g. we have table with language fields: name_en, name_ru, name_zh_cn where we store values for each language (en, ru, zh-CN).

When we try to get object field $model->name;, if current language of an application is en-US the behavior will try to find field name_en_us then name_en. If current language is de and source language is en the behavior will try to find field name_de then name and after the field for source language name_en.

When we try to get object field $model->nameList;, it will try to get all name values for current language. $model->nameList; returns array of values.

Using

By default attribute list consist of an attribute name

/**
 * @property string $name_en
 * @property string $name_ru
 * @property string $name_zh_cn
 */
class Model extends ActiveRecord {
    ...
    public function behaviors()
    {
        return [
            'languageAttribute' => LanguageAttributes::class,
        ];
    }
    ...
}

// this will try to find a value for the current language of an application.
$model->name;

Extended example

/**
 * @property string $name_en
 * @property string $name_ru
 * @property string $name_zh_cn
 * @property string $field_en
 * @property string $field_ru
 * @property string $field_zh_cn
 * @property string $status
 */
class Model extends ActiveRecord {
    ...
    public function behaviors()
    {
        return [
            'languageAttribute' => [
                'class' => LanguageAttributes::class,
                'attributes' => ['name', 'field'],
                'languages' => ['en', 'ru', 'zh_cn'],
                'query' => ['where' => ['status' => 'active']],
                'sort' => true,
            ]
        ];
    }
    ...
}

// Try to find values for the current language of an application.
$model->name;
$model->field;

// Get list of all values from a model table for the current language
$model->nameList;
$model->fieldList;

// Copy all language values from $model2->name to $model->name
$model->copyValue($model2, 'name');

// Copy all language values from $model2->field2 to $model->field
$model->copyValue($model2, 'field2', 'field');
