我正在使用 OC 2.2.0，现在一直在努力解决以下问题:
示例:我在标题搜索中输入西门子并单击显示所有结果，我的搜索页面出现了所有结果。问题是 - 结果列表仅包含名称中包含西门子的产品。我需要的是在搜索结果列表中显示属于该制造商的所有 产品，在我们的示例中是西门子制造商。在我的 search.php Controller 文件中，结果在这一行中定义:
$results = $this->model_catalog_product->getProducts($filter_data);
这告诉我 model-catalog-product 中 product.php 文件的 getProducts($filter_data) 函数是我需要定义结果的地方。我尝试调整此函数中的查询，使其在搜索结果中也包含制造商，但没有成功。到目前为止，我的 getProducts($filter_data) 函数如下所示:
public function getProducts($data = array()) {
$sql = "SELECT p.product_id, (SELECT AVG(rating) AS total FROM " . DB_PREFIX . "review r1 WHERE r1.product_id = p.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating, (SELECT price FROM " . DB_PREFIX . "product_discount pd2 WHERE pd2.product_id = p.product_id AND pd2.customer_group_id = '" . (int)$this->config->get('config_customer_group_id') . "' AND pd2.quantity = '1' AND ((pd2.date_start = '0000-00-00' OR pd2.date_start < NOW()) AND (pd2.date_end = '0000-00-00' OR pd2.date_end > NOW())) ORDER BY pd2.priority ASC, pd2.price ASC LIMIT 1) AS discount, (SELECT price FROM " . DB_PREFIX . "product_special ps WHERE ps.product_id = p.product_id AND ps.customer_group_id = '" . (int)$this->config->get('config_customer_group_id') . "' AND ((ps.date_start = '0000-00-00' OR ps.date_start < NOW()) AND (ps.date_end = '0000-00-00' OR ps.date_end > NOW())) ORDER BY ps.priority ASC, ps.price ASC LIMIT 1) AS special";

任何人都可以帮助调整查询，以便它可以显示属于搜索到的制造商的所有产品吗？
提前谢谢你。
最佳答案
所以，我终于意识到缺少的查询是什么。行前
$sql .= " LEFT JOIN " . DB_PREFIX . "product_description pd ON
(p.product_id = pd.product_id) LEFT JOIN " . DB_PREFIX .
"product_to_store p2s
我不得不输入 $sql .= "LEFT JOIN "。数据库前缀。 "制造商 m ON (m.manufacturer_id = p.manufacturer_id) ";
然后就在行之前
$sql .= " OR LCASE(p.model) = '" . $this->db->escape(utf8_strtolower($data['filter_name'])) . "'";
我不得不把
$sql .= " OR LCASE(m.name) = '" . $this->db->escape(utf8_strtolower($data['filter_name'])) . "'";
很明显我遗漏了制造商数据。这样我从制造商表中提取数据并正确处理它。我希望这对某人有帮助，干杯!
