在 opencart 中显示子类别中的图像

2023-12-04

最近我第一次安装了Opencart 1.5.6。一切都很好，除了我试图在子类别中显示图像和文本（其中是“优化搜索文本”）。到目前为止我已经把这个放进去了catalog\controller\module\category.php

$children_data[] = array(
    'category_id' => $child['category_id'],
    'name'        => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $product_total . ')' : ''),
    'image'       => $category['image'],
    'href'        => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id']) 
);      
}

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

新事物是'image' => $category['image'],。我也稍微改变一下catalog\view\theme\MYTHEME\template\product\category.tpl像这样：

<ul>
  <?php foreach ($categories as $category) { ?>

  <li>
      <img src="../../../../../../image/data/models/<?php echo $category['image']; ?>" width="100"/>
      <a href="<?php echo $category['href']; ?>"><?php echo $category['name']; ?></a>
  </li>

  <?php } ?>
</ul>
<ul>
  <?php $j = $i + ceil(count($categories) / 4); ?>
  <?php for (; $i < $j; $i++) { ?>
  <?php if (isset($categories[$i])) { ?>
  <li>
      <img src="../../../../../../image/data/models/<?php echo $categories['image']; ?>" width="100"/>
      <a href="<?php echo $categories[$i]['href']; ?>"><?php echo $categories[$i]['name']; ?></a></li>

    <?php } ?>
  <?php } ?>
</ul>

The result is box with broken image and text under the image. This

我可以从错误中看到它是什么，但不知道如何修复它<img src="../../../../../../image/data/models/Notice: Undefined index: image in ..\catalog\view\theme\mytheme\template\product\category.tpl on line 29" width="100"/>

尝试类似默认 OpenCart 代码的操作。

Step 1

打开文件catalog/view/theme/<your theme>/template/template/category.tpl

Find：细化类别代码。

添加后 <div class="category-list">开始div

<?php $counter = 0; foreach ($categories as $category) {?>  
            <div>
                <?php if ($category['thumb']) { ?>
                <a href="<?php echo $category['href']; ?>"><img src="<?php echo $category['thumb']; ?>" alt="<?php echo $category['name']; ?>" /></a>
                <?php } else { ?>
                <a href="<?php echo $category['href']; ?>"><img src="image/no_image.jpg" alt="<?php echo $category['name']; ?>" /></a>
                <?php } ?>
                <a href="<?php echo $category['href']; ?>"><?php echo $category['name']; ?></a>
            </div>
    <?php $counter++; } ?>

Step 2

打开文件catalog/controller/product/category.php

Find :

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

添加后

$image = $this->model_tool_image->resize($result['image'], $this->config->get('config_image_category_width'), $this->config->get('config_image_category_height'));

Step 3

在同一个文件中catalog/controller/product/category.php

Find :

'href'  => $this->url->link('product/category', 'path=' . $this->request->get['path'] . '_' . $result['category_id'] . $url)

Replace（而不是上面的线）

'href'  => $this->url->link('product/category', 'path=' . $this->request->get['path'] . '_' . $result['category_id'] . $url), 'thumb' => $image

然后检查一下。
