Error in getting the last inserted ID of a query using batch insert in CodeIgniter

Question

How can I get the last inserted ID of a query using the batch insert in CodeIgniter. I used the code $this->db->insert_id() but it returns the ID of my fi

Answer 1

I think the best way would be to use the batch insert instead of individual inserts in a loop for performance , but to get the last insert id, ADD the First Insert ID & the Affected Rows.

$this->db->insert_batch('po_order', $orders);
$total_affected_rows = $this->db->affected_rows();
$first_insert_id = $this->db->insert_id();

$last_id = ($first_insert_id + $total_affected_rows - 1);
