Fetch featured product only from product table in Api

Product Table

where i want to fetch only featured product. I have defined a column in database product_type in which four types of products(hot deals, newly listed, deals of the day and featured product)strong text can be listed which is optional.

Blockquote

   Here is my model|query code in codeigniter
    

 public function featured_product()
 {
    $arrResult = array();
    
    $this->db->select('*');
    $this->db->from('product');
    $this->db->where("product_type","featured");
    $result = $this->db->get()->result_array();
    if(!empty($result))
    {
        $arrResult['result'] = $result;
    }
    else
    {
        $arrResult['result'] = '';
    }
    return $arrResult ;
  }

When i try to fetch whole product list in api i get the result but i want to show only featured product.

Answer

As I have changed my database to separate table with product_id matching with product_type. Still I find the solution to my question with a function FIND_IN_SET().

Here is my updated modal query:

public function featured_product()
{
    $arrResponse = array();
    $data = 'featured';
    $this->db->select('*');
    $this->db->where('find_in_set("'.$data.'", product_type) <> 0');
    $this->db->from('product');
    $result = $this->db->get()->result_array();
    if(!empty($result))
    {
        $arrResponse['result'] = $result;
    }
    else
    {
        $arrResponse['result'] = '';
    }
    return $arrResponse ;
 }
