Question

I am trying to delete multiple record(s) by using codeigniter

$this->db->delete() and $this->db->where()

I want to delete record(s) with an array like

$id =array(
  0=>'13',   //13 is the id
  1=>'4',    //4 is the id
  2=>'2'     //2 is the id
); 

The array was generated by the users so it will be dynamic.
I just want to know if codeigniter can take the array as a option in delete method.

According to this. http://codeigniter.com/user_guide/database/active_record.html

array won’t work in the following method.

$this->db->delete()
$this->db->where('id', $id); //I don't think I can do this. 

I could use foreach to loop but it seems to me there are better ways. I was wondering if anyone could help me about it. Thanks a lot.

Not really familiar with codeigniters active record but I believe the stmt you would like is:

$sql = "DELETE FROM tbl WHERE id IN (".implode(',',$idsToDelete.");";
$this->db->query($sql);

This might work better with active record:

$this->db->where('IN ('.implode(',',$idsToDelete).')', NULL, FALSE);
$this->db->delete();
