Question

I’ve seen people use this piece of code and I’m trying to understand what it does because I don’t see it in any of the codeigniter documenation or in the source code for the database class.

$this->db->ar_orderby

Answer 1

This is an array that holds order by columns..

There should be no reason to use this property directly. Instead call $this->db->order_by('column') which appends to the array automatically.

• defined in system/database/DB_active_rec.php Line 42
• appended to in method CI_DB_active_record::order_by Line 856
• used to generate SQL in CI_DB_active_record::_compile_select Line 1781
