CodeIgniter数组信息

Question

from print_r

Array (
    [0] => stdClass Object (
        [id] => 2729
        [title] =>
        [image_file] => M6_Black_Back.jpg
        [product] => 2
        [active] => 0
        [created] => 2013-06-19 23:14:51
        [rank] => 1
        [publish] => 0
        [back_photo] => M6_Black_Back.jpg
    )
)

this is in my controller

$data['back'] = $this->global_model->custom_query('
        SELECT *,image_file AS back_photo FROM system_product_photos
        WHERE product = 2 AND rank = 1
        ');

$this->load->view('template', $data);

I can't for the life of me get <?=$back->back_photo?> to output anything. Warning codeignighter rookie alert!

$back, in your view, is an array. You're going to need to access the specific item by index <?=$back[0]->back_photo?>, or change the signature of custom_query to only return one item.
