home.php中的未定义索引Opencart

[英]Undefined index Opencart in home.php

Opencart版本1.5.5.1

我添加一些代码:在home.php中,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;
}

我添加代码$this->dell(); ,我已经尝试过var_dump($this->data['product_dell'][1][1])并且可以正常使用。

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时出现了这样的错误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$product[1][1][1] until $product[7][7][7]数组, $product[1][1][1] until $product[7][7][7]

组菜单1-7的第一个[1]

子菜单的第二个[1] (例如1个菜单有5个子菜单)

第3个[1]用于描述1个孩子(例如名称,dll)

然后在视图中,我使用for进行显示,其工作方式如下: $name = $product_dell[1][$i][0];

它在'name'写入未定义的索引,这意味着在控制器$all_data['name'],也是另一个。

当我尝试var_dump($product_dell[1][1]); 在视图中,它正在工作(成功传递变量),idwk为什么会出错以及如何解决此问题?

感谢您的评论,我不断尝试后得到了答案。

在像这样将数据传递给变量后,在Open cart (in my case)为例)中

 $all_data = $this->model_catalog_item->select_description_dll($id);

我不能这样传递数据(这样从数据库中获取数据):

 if(isset($all_data)){
    $this->data['product_dell'][$i][] = array(
         $all_data['name'],         // Error undefined index name !!!
         $all_data['shortDescription'], // Error undefined index shoertDescription !!!
         $all_data['image'],        // Error undefined index image !!!
         $all_data['price'],       // Error undefined index price !!!
    );
 }

所以我这样改变variable

if(isset($all_data['name']))
    $name = $all_data['name'];
else
    $name = null;

然后再次存储到array

if(isset($all_data)){
    $this->data['product_dell'][$i][] = array(
        $name,
        $.....,
    );
}

它正在工作:)
