OpenCart - 显示类别菜单模块的类别说明。 尝试在类别列表上显示类别图像和描述,图像工作正常,但类别的描述不起作用。
此处为目录\ controller \ module \ category.php
<?php
class ControllerModuleCategory extends Controller {
protected function index($setting) {
$this->language->load('module/category');
$this->data['heading_title'] = $this->language->get('heading_title');
if (isset($this->request->get['path'])) {
$parts = explode('_', (string)$this->request->get['path']);
} else {
$parts = array();
}
if (isset($parts[0])) {
$this->data['category_id'] = $parts[0];
} else {
$this->data['category_id'] = 0;
}
if (isset($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) {
$total = $this->model_catalog_product->getTotalProducts(array('filter_category_id' => $category['category_id']));
$children_data = array();
$children = $this->model_catalog_category->getCategories($category['category_id']);
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 . ')' : ''),
'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id'])
);
}
// image cat code
$this->load->model('tool/image');
$image = empty($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 . ')' : ''),
'children' => $children_data,
'thumb' => $thumb,
'href' => $this->url->link('product/category', 'path=' . $category['category_id'])
);
}
if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/module/category.tpl')) {
$this->template = $this->config->get('config_template') . '/template/module/category.tpl';
} else {
$this->template = 'default/template/module/category.tpl';
}
$this->render();
}
}
?>
这里是template \ module \ 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>

有两个问题:
1。您没有在控制器中设置类别说明
2。模板引用了一个空白变量,因为$category_info
变量未在控制器中设置,因此说明不起作用,解决方法如下。
将该行添加到下面显示的控制器中:
$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'])
);
现在在模板中通过字符串声明变量:
<div class="desc">
<?php echo $category['description']; ?>
<div class="img-desc"><img src="<?php echo $category['thumb']; ?>" /></div>
</div>

问题在于缺少html_entity_decode。
替换:
'description' => $category['description'],
使用:
'description' => html_entity_decode($category['description'], ENT_QUOTES, 'UTF-8'),
