我在OpenCart中遇到了此問題,我想以自定義方式顯示我的商店類別並計算父類別。在OpenCart中顯示和計算類別
目前,我修改了代碼,到目前爲止,我得到下面的輸出
<ul id="catOpContainer">
<li id="switchCatOp1">Parent Cat 1
<ul id="catOp1">
<li>Child cat 1</li>
Child Cat 2</li>
</ul>
</li>
Parent Cat 2
<ul id="catOp1">
<li>Child cat 1</li>
Child cat 2</li>
</ul>
</li>
Parent Cat 3</li>
</ul>
</ul>
,而不是期望
<ul id="catOpContainer">
<li id="switchCatOp1">Parent Cat 1
<ul id="catOp1">
<li>Child Cat 1</li>
<li>Child Cat 2</li>
</ul>
</li>
<li id="switchCatOp2">Parent Cat 2
<ul id="catOp2">
<li>Child Cat 1</li>
<li>Child Cat 2</li>
<li>Child Cat 3</li>
</ul>
</li>
</ul>
很明顯,有一些缺少的元素,但我不知道有關可能的解決方案。我也不知道如何計算父類別,以便我可以切換子類別。
目前,我有下面的代碼片段:
<?php
class ControllerModuleCategory extends Controller {
protected $category_id = 0;
protected $path = array();
protected function index() {
$this->language->load('module/category');
$this->data['heading_title'] = $this->language->get('heading_title');
$this->load->model('catalog/category');
$this->load->model('tool/seo_url');
if (isset($this->request->get['path'])) {
$this->path = explode('_', $this->request->get['path']);
$this->category_id = end($this->path);
}
$this->data['category'] = $this->getCategories(0);
$this->id = 'category';
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';
}
$this->render();
}
protected function getCategories($parent_id, $current_path = '') {
$category_id = array_shift($this->path);
$output = '';
$results = $this->model_catalog_category->getCategories($parent_id);
if ($results) {
if ($parent_id == 0) {
$output .= '<li id="switchCatOp1">';
} else {
$output .= '<ul id="catOp1"><li>';
}
}
foreach ($results as $result) {
if (!$current_path) {
$new_path = $result['category_id'];
} else {
$new_path = $current_path . '_' . $result['category_id'];
}
$output .= '';
$children = '';
// if ($category_id == $result['category_id']) {
$children = $this->getCategories($result['category_id'], $new_path);
// }
if ($this->category_id == $result['category_id']) {
$output .= '<a href="' . $this->model_tool_seo_url->rewrite(HTTP_SERVER . 'index.php?route=product/category&path=' . $new_path) . '">' . $result['name'] . '</a>';
} else {
$output .= '<a href="' . $this->model_tool_seo_url->rewrite(HTTP_SERVER . 'index.php?route=product/category&path=' . $new_path) . '">' . $result['name'] . '</a>';
}
$output .= $children;
$output .= '</li>';
}
if ($results) {
$output .= '</ul>';
}
return $output;
}
}
?>
我真的希望有人知道的解決方案。
