Я пробовал все этапы других подобных предыдущих вопросов, но он не работал. Я хочу получить подкатегорию 3-го уровня в верхнем меню Opencart v2.3
Этот ниже код имеет 2levelcategory, мне нужно создать категорию 3 уровня. Это код файла header.php
$categories = $this->model_catalog_category->getCategories(0); foreach ($categories as $category) { if ($category['top']) { // Level 2 $children_data = array(); $children = $this->model_catalog_category->getCategories($category['category_id']); foreach ($children as $child) { $filter_data = array( 'filter_category_id' => $child['category_id'], 'filter_sub_category' => true ); $children_data[] = array( 'name' => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''), 'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id']) ); } // Level 1 $data['categories'][] = array( 'name' => $category['name'], 'children' => $children_data, 'column' => $category['column'] ? $category['column'] : 1, 'href' => $this->url->link('product/category', 'path=' . $category['category_id']) ); } }
Это код файла header.tpl
<ul class="nav navbar-nav"> <?php foreach ($categories as $category) { ?> <?php if ($category['children']) { ?> <li class="dropdown"><a href="<?php echo $category['href']; ?>" class="dropdown-toggle" data-toggle="dropdown"><?php echo $category['name']; ?></a> <div class="dropdown-menu"> <div class="dropdown-inner"> <?php foreach (array_chunk($category['children'], ceil(count($category['children']) / $category['column'])) as $children) { ?> <ul class="list-unstyled"> <?php foreach ($children as $child) { ?> <li><a href="<?php echo $child['href']; ?>"><?php echo $child['name']; ?></a></li> <?php } ?> </ul> <?php } ?> </div> <a href="<?php echo $category['href']; ?>" class="see-all"><?php echo $text_all; ?> <?php echo $category['name']; ?></a> </div> </li> <?php } else { ?> <li><a href="<?php echo $category['href']; ?>"><?php echo $category['name']; ?></a></li> <?php } ?> <?php } ?> </ul>
Вы можете добавить 3-й уровень таких категорий: файл контроллера:
$categories = $this->model_catalog_category->getCategories(0); foreach ($categories as $category) { if ($category['top']) { // Level 2 $children_data = array(); $children = $this->model_catalog_category->getCategories($category['category_id']); foreach ($children as $child) { // Level 3 $grandchildren_data = array(); $grandchildren = $this->model_catalog_category->getCategories($child['category_id']); foreach ($grandchildren as $grandchild) { $grandchild_filter_data = array( 'filter_category_id' => $grandchild['category_id'], 'filter_sub_category' => true ); $grandchildren_data[] = array( 'name' => $grandchild['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($grandchild_filter_data) . ')' : ''), 'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $grandchild['category_id']) ); } $filter_data = array( 'filter_category_id' => $child['category_id'], 'filter_sub_category' => true ); $children_data[] = array( 'name' => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''), 'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id']), 'children' => $grandchildren_data, ); } // Level 1 $data['categories'][] = array( 'name' => $category['name'], 'children' => $children_data, 'column' => $category['column'] ? $category['column'] : 1, 'href' => $this->url->link('product/category', 'path=' . $category['category_id']) ); } }
посмотреть файл:
<ul class="nav navbar-nav"> <?php foreach ($categories as $category) { ?> <?php if ($category['children']) { ?> <li class="dropdown"><a href="<?php echo $category['href']; ?>" class="dropdown-toggle" data-toggle="dropdown"><?php echo $category['name']; ?></a> <div class="dropdown-menu"> <div class="dropdown-inner"> <?php foreach (array_chunk($category['children'], ceil(count($category['children']) / $category['column'])) as $children) { ?> <ul class="list-unstyled"> <?php foreach ($children as $child) { ?> <li> <a href="<?php echo $child['href']; ?>"><?php echo $child['name']; ?></a> <?php if($child['children']){ ?> <ul> <?php foreach ($child['children'] as $child) { ?> <li><a href="<?php echo $child['href']; ?>"><?php echo $child['name']; ?></a></li> <?php } ?> </ul> <?php } ?> </li> <?php } ?> </ul> <?php } ?> </div> <a href="<?php echo $category['href']; ?>" class="see-all"><?php echo $text_all; ?> <?php echo $category['name']; ?></a> </div> </li> <?php } else { ?> <li><a href="<?php echo $category['href']; ?>"><?php echo $category['name']; ?></a></li> <?php } ?> <?php } ?> </ul>
Я тестировал свою работу над opencart 2.3.0.2 с темой по умолчанию:
