How to add an ORDER BY clause using CodeIgniter's Active Record methods?

Question

I have a very small script to get all records from a database table, the code is below.

$query = $this->db->get($this->table_name);
return $query->         


        

Answer 1

Using this code to multiple order by in single query.

$this->db->from($this->table_name);
$this->db->order_by("column1 asc,column2 desc");
$query = $this->db->get(); 
return $query->result();

Answer 2

Just add the'order_by' clause to your code and modify it to look just like the one below.

$this->db->order_by('name', 'asc');
$result = $this->db->get($table);

There you go.

Answer 3

Simple and easy:

$this->db->order_by("name", "asc");
$query = $this->db->get($this->table_name);
return $query->result();

Answer 4

function getProductionGroupItems($itemId){
     $this->db->select("*");
     $this->db->where("id",$itemId);
     $this->db->or_where("parent_item_id",$itemId);

    /*********** order by *********** */
     $this->db->order_by("id", "asc");

     $q=$this->db->get("recipe_products");
     if($q->num_rows()>0){
         foreach($q->result() as $row){
             $data[]=$row;
         }
         return $data;
     }
    return false;
}

Answer 5

I believe the get() function immediately runs the select query and does not accept ORDER BY conditions as parameters. I think you'll need to separately declare the conditions, then run the query. Give this a try:

$this->db->from($this->table_name);
$this->db->order_by("name", "asc");
$query = $this->db->get(); 
return $query->result();
