Question

我为OC2.3创建了一个新的简单模块，该模块从OC product_special表中获取了一些数据。

我有点堆积，刷新模块模板时我总是黑屏。我的错误电话是什么，无法从模型查询中获取值？

因此，放置在admin / controller / extension / module中的名为SpecialPrices.php的控制器文件包含以下信息：

    <?php
   class ControllerExtensionModuleSpecialprices extends Controller {
    private $error = array();

   public function index() {

   ..............................

    }

// My new function

   public function myFunction() {

        $this->load->language('extension/module/SpecialPrices');
        $this->document->setTitle($this->language->get('heading_title'));
        $this->load->model('extension/module/SpecialPrices');

        $products = $this->model_extension_module_SpecialPrices->getProductSpecials($data);

            foreach ($products as $product) {
                $data['products'][] = array(
                    'product_id' => $product['product_id'],
                    'price'       => $product_info['price']

                );
            }

        $data['heading_title'] = $this->language->get('heading_title');
        $data['text_edit'] = $this->language->get('text_edit');
        $data['text_title'] = $this->language->get('text_title');
        $data['text_product_id'] = $this->language->get('text_product_id');
        $data['text_price'] = $this->language->get('text_price');

        $data['header'] = $this->load->controller('common/header');
        $data['column_left'] = $this->load->controller('common/column_left');
        $data['footer'] = $this->load->controller('common/footer');


        $this->response->setOutput($this->load->view('extension/module   /SpecialPrices', $data));

    }

   ...........

我在admin / model / extension /模块中名为SpecialPrices.php的模型文件包含...

    public function getProductSpecials($data) {

    $sql = "SELECT * FROM `" . DB_PREFIX ."product_special` ";
    $query = $this->db->query($sql);
    return $query->rows;
    }

在我的模板SpecialPrices.tpl中，该文件在路径admin / view / template / extension / module中创建，试图从上述查询中获取值
```
<?php echo $header; ?><?php echo $column_left; ?>

<div id="content">
<div class="page-header"> 
.......
<?php echo $product_id; ?>
<?php echo $price; ?>
.........
```
1. 在admin / language / zh-CN / extension / module中有SpecialPrices.php

//文字 $ _ ['text_extension'] ='扩展名'; $ _ ['text_success'] ='成功：您已经在产品中插入了批量特惠价！'; $ _ ['text_edit'] ='编辑批量特惠价格模块';

乍看之下，您在module之后留了空格：

$this->response->setOutput($this->load->view('extension/module   /SpecialPrices', $data));

必须是：

$this->response->setOutput($this->load->view('extension/module/SpecialPrices', $data));

您在错误日志中收到哪些错误？在控制器文件中，应将代码放置到public function index() {//your code}或在某个位置调用函数。我看不到您在哪里打电话。如果您有在tpl中调用的数据数组，则应按以下步骤操作：

<?php foreach ($products as $product) { ?>

<?php echo $product['product_id']; ?>
<?php echo $product['price']; ?>
<?php }?>

好。编辑并工作：控制器mymodule.php：

 <?php
class ControllerExtensionModuleMymodule extends Controller {

  public function index() {

        $this->load->language('extension/module/mymodule');
        $this->document->setTitle($this->language->get('heading_title'));
        $this->load->model('extension/module/mymodule');

        $products = $this->model_extension_module_mymodule->getProductSpecials();

            foreach ($products as $product) {
                $data['products'][] = array(
                    'product_id' => $product['product_id'],
                    'price'       => $product['price']

                );
            }

            $data['heading_title'] = $this->language->get('heading_title');
        $data['text_edit'] = $this->language->get('text_edit');
        $data['text_title'] = $this->language->get('text_title');
        $data['text_product_id'] = $this->language->get('text_product_id');
        $data['text_price'] = $this->language->get('text_price');




       $data['header'] = $this->load->controller('common/header');
        $data['column_left'] = $this->load->controller('common/column_left');
        $data['footer'] = $this->load->controller('common/footer');

        $this->response->setOutput($this->load->view('extension/module/mymodule', $data));
    }

 }

模型... mymodule.php：

 <?php
 class ModelExtensionModuleMymodule extends Model {
 public function getProductSpecials() {

    $sql = "SELECT * FROM `" . DB_PREFIX ."product_special` ";
    $query = $this->db->query($sql);
    return $query->rows;
    }
 }

mumodule.tpl：

<?php echo $header; ?><?php echo $column_left; ?>
<div id="content">
  <div class="page-header">
<div class="container-fluid">
<?php foreach ($products as $product) { ?>

<?php echo $product['product_id']; ?>
<?php echo $product['price']; ?>
<?php }?>
</div>
</div>
</div>
<?php echo $footer; ?>

添加文件后，不要忘记在admin> setting> usergroup> Administrator
