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
    )
)

这在我的控制器中

$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);

我一辈子都不能让<?=$back->back_photo?>输出任何东西。警告代码识别更高的新手警报！

$back在您的视图中是一个数组。您将需要通过索引<?=$back[0]->back_photo?>访问特定项，或者将custom_query的签名更改为只返回一个项。
