Answer 1

The database LIKE function only creates a LIKE in the SQL statement. You'll still need to call the GET mothod afterwards; Like this;
$this->db->like('name', $id);
$q = $this->db->get();

Answer 2

You are using $this->db_like() incorrectly.
$this->db->like('title', 'match');
// Produces: WHERE title LIKE '%match%'
(from documentation)
In your case the usage would be
$this->db->like('name', 'rice')

Answer 3

public function fetchdeal_products($id)
{
$query = $this->db->query("Select products.* From products Where (products.name Like '%$id%')");
$result = $query->result_array();
return $result;
}

Answer 4

you have to write it as bellow.
public function fetchdeal_products($id) {
$this->db->like("name", $id);
$q = $this->db->get('products');
if ($q->num_rows() > 0) {
foreach (($q->result()) as $row) {
$data[] = $row;
}
return $data;
}
}
