OpenCart - 显示类别菜单模块上的类别描述。尝试在类别列表中显示类别图像和说明，图像正常工作，但该类别的说明不起作用。OpenCart - 显示类别菜单模块上的类别描述

这里目录\控制器\模块\ category.php

<?php 
class ControllerModuleCategory extends Controller { 
    protected function index($setting) { 
     $this->language->load('module/category'); 

     $this->data['heading_title'] = $this->language->get('heading_title');

      $this->data['category_id'] = 0; 
     } 

     if (isset($parts[1])) { 
      $this->data['child_id'] = $parts[1]; 
     } else { 
      $this->data['child_id'] = 0; 
     } 

     $this->load->model('catalog/category'); 

     $this->load->model('catalog/product'); 

     $this->data['categories'] = array(); 

     $categories = $this->model_catalog_category->getCategories(0); 

     foreach ($categories as $category) {

      foreach ($children as $child) { 
       $data = array(
        'filter_category_id' => $child['category_id'], 
        'filter_sub_category' => true 
       ); 

       $product_total = $this->model_catalog_product->getTotalProducts($data); 

       $total += $product_total; 

       $children_data[] = array(
        'category_id' => $child['category_id'], 
        'name'  => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $product_total . ')' : ''),

      // image cat code

      $image = empty($category['image']) ? 'no_image.jpg' : $category['image']; 
      $thumb = $this->model_tool_image->resize($image, 50, 127); 



      $this->data['categories'][] = array(
       'category_id' => $category['category_id'], 
       'name'  => $category['name'] . ($this->config->get('config_product_count') ? ' (' . $total . ')' : ''),

      $this->template = 'default/template/module/category.tpl'; 
     } 

     $this->render(); 
    }

这里模板\模块\ category.tpl

<div class="menu-left"> 
    <div class="title"><?php echo $heading_title; ?></div> 

    <ul> 
     <?php foreach ($categories as $category) { ?> 
     <li class="sub"> 
     <?php if ($category['category_id'] == $category_id) { ?> 
     <span> <a href="<?php echo $category['href']; ?>" class="active"><?php echo $category['name']; ?></a></span> 
     <?php } else { ?> 
     <span><a href="<?php echo $category['href']; ?>"><?php echo $category['name']; ?></a></span> 
     <?php } ?> 
     <?php if ($category['children']) { ?> 
    <div class="panel"> 
     <ul> 
      <?php foreach ($category['children'] as $child) { ?> 
      <li> 
      <?php if ($child['category_id'] == $child_id) { ?> 
      <a href="<?php echo $child['href']; ?>" class="active"> - <?php echo $child['name']; ?></a> 
      <?php } else { ?> 
      <a href="<?php echo $child['href']; ?>"> - <?php echo $child['name']; ?></a> 
      <?php } ?> 
      </li> 
      <?php } ?> 
     </ul> 


    <div class="desc"> 

<?php if(isset($category_info)) { ?> 
<?php echo $category_info['description']; ?> 
<?php } ?> 
    <div class="img-desc"><img src="<?php echo $category['thumb']; ?>" /></div> 


    </div> 



     </div> 
     <?php } ?> 
     </li> 
     <?php } ?> 
    </ul> 

</div>

'但类别的描述并不work'这是什么，你可以提供有关该问题的一些更详细 – 2013-05-12 12:14:28

答

有两个问题：

1。您没有在控制器中设置类别描述。
2.由于$category_info变量没有在控制器中设置，因此该模板引用了空白变量，因此该描述不起作用，解决方案如下。

添加行成下图所示的控制器：

  $this->data['categories'][] = array(
       'category_id' => $category['category_id'], 
       'name'  => $category['name'] . ($this->config->get('config_product_count') ? ' (' . $total . ')' : ''), 
       'children' => $children_data, 
       'thumb'  => $thumb, 
/*THIS IS NEW*/ 'description' => $category['description'], 
       'href'  => $this->url->link('product/category', 'path=' . $category['category_id']) 
      );

现在宣布通过字符串变量在你的模板：

<div class="desc"> 
    <?php echo $category['description']; ?> 
    <div class="img-desc"><img src="<?php echo $category['thumb']; ?>" /></div> 
</div>

答

问题是与缺乏html_entity_decode。

替换：

'description' => $category['description'],

有了：

'description' => html_entity_decode($category['description'], ENT_QUOTES, 'UTF-8'),
