hi there!.. basic stuff here again
i cant understand this
i just want to read only 1 field of my DB... the content of the Image from some ID

here is what i am doing

Code:
$this->db->select('image');

$this->db->where('id', $id); 

$JustTheImage = $this->db->get('post');

but by the whole things i've try to readit the only one that works is just a forech
a foreach for a single thing has no sense

you have to add

Code:
$result = $this->db->get('post');

$row = $result->row();

$row->image;

in php5 you can do

Code:
$this->db->select('image')->from('post')->where('id', $id)->get()->row()->image;
