i have a problem in my search form. In my database all data is in upper case , so when i input lower case letter in search field it do not gives any result. So i trying to find out how to make my form insensitive.
This is the model:
// chassis
    public function chassis($chassis)
    {
        return $this->builder->where('model_type_en', 'LIKE', "%$chassis%");
    }
Do you have any ideas how i can use upper(model_type_en) in this function?
