[solved] get db result

[eluser]kaejiavo[/eluser]
Hi guys,

i have a problem with a db result. My code:

Code:

function get_shop_items($shop_id) {
    $this->db->select('items_id');
    $this->db->where('shops_id', $shop_id);
    $this->db->from('item_shops');
    $query = $this->db->get();

    return $query->result_array();
    }

returns an array:

Code:

Array ( [0] => Array ( [items_id] => 3 ) [1] => Array ( [items_id] => 7 ) )

but i need:

Code:

Array ( [0] =>  3 [1] => 7 )

because i want to use it to select options in a form_multiselect.

Is there any way to return only the values with db library, or do i have to circle the values and build my own array?

TIA
Marco
