How to get data from database by using an array of ids in codeigniter?

I have an id array in my controller that has checkbox input in a form in views. $toppings = $this->input->get('topping');

Array
(
  [0] => 1
  [1] => 3
  [2] => 4
)

I'm trying to get the information relevant to each id in the array from the database.

    $toppings = $this->input->get('topping');
    foreach ($toppings as $topping ) {
        $id = $topping;
        $toppinglist = $this->toppingmodel->find_topping($id);
        echo'<pre>'; print_r($toppinglist); die();

    }

Model Class -

function find_topping($id)
{
    $query = $this->db->get_where('Topping', array('id' => $id));
    return $query->row_array(); }

}

The output array i'm getting is only the data for the first id

Array
(
  [id] => 1
  [slug] => mushroom
  [toppingName] => Mushrooms
  [price] => 50.00
)

How can i get all the data relevant to each id in an array. (nested array) Thank you.

Controller:-

$toppings = $this->input->post('topping');    //Array         
$toppinglist = $this->toppingmodel->find_topping($toppings);

model:-

function find_topping($idArr = array()){         //Array  
 $query = $this->db->where_in("Topping", $idArr)->get("tablename");
     return $query->result_array();
}

Note:- $idArr = array() means

make the function have a default value of array otherwise if something else is passed you'll get an error in your query.

You need to make your SQL query with WHERE IN().

In Codeignitor you can use $this->db->where_in($tableName, $arrayOfVales). Learn more here

Code Example

function find_topping(array $ids)
{
    $query = $this->db->where_in('Topping', $ids);
    return $query->result_array(); 
}
