未定义的索引 Opencart in home.php.

Opencart 版本 1.5.5.1

我添加了一些代码：在主页中.php然后在 home.tpl 中显示

控制器：

<?php  
class ControllerCommonHome extends Controller {
public function index() {
    $this->document->setTitle($this->config->get('config_title'));
    $this->document->setDescription($this->config->get('config_meta_description'));
    $this->data['heading_title'] = $this->config->get('config_title');
    $this->dell(); // Custom
    if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/common/home.tpl')) {
        $this->template = $this->config->get('config_template') . '/template/common/home.tpl';
    } else {
        $this->template = 'default/template/common/home.tpl';
    }
    $this->children = array(
        'common/column_left',
        'common/column_right',
        'common/content_top',
        'common/content_bottom',
        'common/footer',
        'common/header'
    );
    $this->response->setOutput($this->render());
}
// CUSTOM START HERE -------------------------------
protected function dell() {
    $this->document->setTitle($this->config->get('config_title'));
    $this->document->setDescription($this->config->get('config_meta_description'));
    $this->data['heading_title'] = $this->config->get('config_title');
    $this->load->model('catalog/item');
    for($i=1; $i<=7; $i++)  // START FROM 1
    {
        $menu = array(
            'menu'  => $i,
        );
        $results = $this->model_catalog_item->select_id_dell($menu);
            if(isset($results)){
            $this->data['dell'][] = array(
            $results['show_product_id'],
            $results['head_text'],
            $results['title_text'],
            );
        }
        $this->data['item'] = $this->model_catalog_item->select_item_dell($results);    
        foreach($this->data['item'] as $id){
            $all_data = $this->model_catalog_item->select_description_dll($id);
            if(isset($all_data)){
                $this->data['product_dell'][$i][] = array(
                        $all_data['name'],
                        $all_data['shortDescription'],
                        $all_data['image'],
                        $all_data['price'],
                );
                //var_dump($this->data['product_dell'][1][1]);
            }
        }
    }
}
}
?>

编辑 ： 模型

public function select_description_dll($id){
    $sql = "SELECT * FROM " . DB_PREFIX . "product p LEFT JOIN " . DB_PREFIX . "product_description pd ON (p.product_id = pd.product_id) LEFT JOIN " . DB_PREFIX . "product_to_category p2c ON (p.product_id = p2c.product_id)  WHERE pd.language_id = '" . (int)$this->config->get('config_language_id') . "' && p.product_id = '" . $this->db->escape($id['product_id']) . "' GROUP BY p.product_id";
    //echo $sql; exit;
    $query = $this->db->query($sql);
    return $query->row;
}

我$this->dell();添加代码，我已经尝试var_dump($this->data['product_dell'][1][1])并且它正在工作。

array(1) { [0]=> array(4) { [0]=> string(5) "AAAAA" [1]=> string(2) "aa" [2]=> string(3) "aaa" [3]=> string(2) "00" } } 

但是在显示 home.tpl 中，它是这样的错误http://s1064.photobucket.com/user/blackarch01/media/2016-02-25_14-42-09_zpsqvd3odia.png.html?sort=3&o=0

就我而言，我将数据存储到数组中$product[1][1][1] until $product[7][7][7]

第 1 [1] 组菜单 1-7

子菜单的第 2 [1]（例如 1 个菜单有 5 个孩子）

描述 1 个孩子的第 3 [1]（如姓名、DLL）

然后，我使用for来显示，它的工作是这样的$name = $product_dell[1][$i][0];

它写未定义的索引'name'在控制器$all_data['name'],和另一个中

当我尝试在视图中var_dump($product_dell[1][1]);时，它正在工作（成功传递变量），idwk 为什么它是错误的以及如何修复此???
