如何在opencart的结帐购物车中获取类别？

Question

首先感谢您的帮助...我是 opencart 的新手，希望有人能帮助我...

我疯狂地试图在 google 中找到我的问题的答案...

我想在checkout/cart中添加类别名称

<a href="<?php echo $product['href']; ?>"><?php echo $category['name']; ?></a>

我尝试在 cart.pl 的控制器中添加一个新变量，但这是不可能的，因为我在互联网上找到的答案不起作用...

顺便说一句，我在 Opencart 2.2.0 上工作...

这是我的模板 cart.pl 中的内容：

<?php foreach ($products as $product) { ?>      

                <div class="gry_part">
                        <div class="width1">

                        <a href="<?php echo $product['href']; ?>"><?php echo $category['name']; ?></a> - 
                        <a href="<?php echo $product['href']; ?>"><?php echo $product['name']; ?></a>

                        <?php if (!$product['stock']) { ?>
                          <span class="stock">***</span>
                        <?php } ?>

                        <div>
                            <?php foreach ($product['option'] as $option) { ?>
                            - <small><?php echo $option['name']; ?>: <?php echo $option['value']; ?></small><br />
                            <?php } ?>
                            <?php if($product['recurring']): ?>
                            - <small><?php echo $text_payment_profile ?>: <?php echo $product['profile_name'] ?></small>
                            <?php endif; ?>
                          </div>
                          <?php if ($product['reward']) { ?>
                          <small><?php echo $product['reward']; ?></small>
                          <?php } ?>
                        </div>
                        <div class="width2 quantity">
                            <input type="text" name="quantity[<?php echo $product['cart_id']; ?>]" value="<?php echo $product['quantity']; ?>" size="1" />
                            <input type="image" src="catalog/view/theme/amishop/image/update.png" alt="<?php echo $button_update; ?>" title="<?php echo $button_update; ?>" />
                        </div>
                        <div class="width3"><?php echo $product['price']; ?></div>
                        <div class="width4">
                        <button type="button" data-toggle="tooltip" title="<?php echo $button_remove; ?>" class="add_to99" onclick="cart.remove('<?php echo $product['cart_id']; ?>');">Delete</button>
                        </div>
                    </div>

        <?php } ?>

这就是我尝试在控制器中添加的内容 cart.pl

$categories = $this->model_catalog_product->getCategories($product_id);
        if ($categories)
            $categories_info = $this->model_catalog_category->getCategory($categories[0]['category_id']);
        $this->data['category_title'] = $categories_info['name'];

很抱歉，如果这个问题很愚蠢，但我是新手...

谢谢大家..

Create an OCMOD file - category_on_cart.ocmod.xml

复制以下代码并保存

Create catalog/model/catalog/custom.php

在此文件中添加以下代码。

<?php
class ModelCatalogCustom extends Model {
    public function getproductcategory($product_id){
        $query = $this->db->query("SELECT * FROM " . DB_PREFIX . "product_to_category WHERE product_id = '" . (int)$product_id . "'");
        $category = $this->getCategory($query->row['category_id']);
        return $category['name'];
    }

    public function getCategory($category_id) {
        $query = $this->db->query("SELECT DISTINCT *, (SELECT GROUP_CONCAT(cd1.name ORDER BY level SEPARATOR '&nbsp;&nbsp;&gt;&nbsp;&nbsp;') FROM " . DB_PREFIX . "category_path cp LEFT JOIN " . DB_PREFIX . "category_description cd1 ON (cp.path_id = cd1.category_id AND cp.category_id != cp.path_id) WHERE cp.category_id = c.category_id AND cd1.language_id = '" . (int)$this->config->get('config_language_id') . "' GROUP BY cp.category_id) AS path, (SELECT DISTINCT keyword FROM " . DB_PREFIX . "url_alias WHERE query = 'category_id=" . (int)$category_id . "') AS keyword FROM " . DB_PREFIX . "category c LEFT JOIN " . DB_PREFIX . "category_description cd2 ON (c.category_id = cd2.category_id) WHERE c.category_id = '" . (int)$category_id . "' AND cd2.language_id = '" . (int)$this->config->get('config_language_id') . "'");

        return $query->row;
    }
}

现在转到 Admin dashboard -> Extensions -> Extension installer 安装 category_on_Cart.ocmod.xml 文件。

之后去Admin dashboard-> Extensions->Modifications刷新缓存。点击右上角的刷新按钮第一个按钮。
