Question

i use Active record for inserting values to DB.

All other type of queries i do with custom query as it’s much easier but the active record insert is quite nice.

So i have this code :

    $comment = array (
'point_id' => $object->id,
'title' => $object->title,
'comment' => $object->comment,
'author_name' => $object->author_name,
'is_temp' => 0,
'parent_id' => $object->parent_id

);
return $this->db->insert('comments', $comment);

Now i want to be able to set is_temp as a subquery result, which is :

(SELECT allow_user_comments from subjects where id='somevalue')

How would one achive that?

I was hoping to avoid using third party libraries.

Well, i doubt the fact that that’s how you’re supposed to do it, but ain’t CI all about that?

This is how i got it to work (removing is_temp from the $comment array ofcourse):

$this->db->set($comment);
$this->db->set('is_temp',
'(SELECT allow_user_comments from subjects where id='.$subject_id.')',FALSE);
$this->db->insert('comments');
