The preferred way to install this extension is through composer.

or add

"folkpro/yii2-many-has-many-behaviors" : "*"

Usage

• In your model, add the behavior and configure it

public function behaviors()
{
    return [
        [
            'class' => \folkpro\manyhasmanybehaviors\ManyHasManyBehavior::className(),
            'relations' => [
                 'tags' => 'tag_items',                  
             ],
        ],
    ];
}

• In your model, add the relation, for example:

public function getTags()
{
    return $this->hasMany(Tag::className(), ['id' => 'tag_id'])
        ->viaTable('post_has_tag', ['post_id' => 'id']);
}

• In your model, add validation rules for the attributes created by the behavior, for example:

public function rules()
{
    return [
        [['tag_list'], 'safe']
    ];
}

• In your view, create form fields for the attributes
