Question

我对opencart很新，我想知道如何通过选项或价格修改搜索功能来搜索产品。我有一个项目为我的大学，我需要创建这样的功能。

你能告诉我怎么样吗？我需要一个例子。

Thanx！

我在本例中使用Opencart 1.5.3.1

您需要修改getProducts（）函数。构建时，搜索查询如下所示：

SELECT p.product_id, (SELECT AVG(rating) AS total FROM review r1 WHERE r1.product_id =
p.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating FROM product p LEFT
JOIN product_description pd ON (p.product_id = pd.product_id) LEFT JOIN product_to_store  
p2s ON (p.product_id = p2s.product_id) LEFT JOIN product_tag pt ON (p.product_id = 
pt.product_id) WHERE pd.language_id = '1' AND p.status = '1' AND p.date_available <= NOW  
() AND p2s.store_id = '0' AND ( LCASE(pd.name) LIKE '%large%' OR LCASE(pt.tag) LIKE 
'%large%' AND pt.language_id = '1') GROUP BY p.product_id ORDER BY p.sort_order ASC, LCASE
(pd.name) ASC LIMIT 0,15

您需要向查询添加选项值描述以及向WHERE子句添加参数：

SELECT p.product_id, (SELECT AVG(rating) AS total FROM review r1 WHERE r1.product_id = 
p.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating FROM product p LEFT 
JOIN product_description pd ON (p.product_id = pd.product_id) LEFT JOIN 
product_to_store p2s ON (p.product_id = p2s.product_id) LEFT JOIN product_option_value 
pov ON (p.product_id = pov.product_id) LEFT JOIN option_value_description ovd ON 
(pov.option_value_id = ovd.option_value_id) LEFT JOIN product_tag pt ON (p.product_id 
= pt.product_id) WHERE pd.language_id = '1' AND p.status = '1' AND p.date_available <= 
NOW() AND p2s.store_id = '0' AND ( LCASE(pd.name) LIKE '%large%' OR LCASE(ovd.name) 
LIKE '%large%' OR LCASE(pt.tag) LIKE '%large%' AND pt.language_id = '1') GROUP BY  
p.product_id ORDER BY p.sort_order ASC, LCASE(pd.name) ASC LIMIT 0,15

为此，请编辑catalog / model / catalog / product.php。找到第37,38行：

        if (!$product_data) {
        $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 FROM " . DB_PREFIX . "product p LEFT JOIN " . 
DB_PREFIX . "product_description pd ON (p.product_id = pd.product_id) LEFT JOIN " . 
DB_PREFIX . "product_to_store p2s ON (p.product_id = p2s.product_id)";

之后添加：

            //add option values to search query
        $sql.= " LEFT JOIN " . DB_PREFIX . "product_option_value pov ON (p.product_id = pov.product_id)";   
        $sql.= " LEFT JOIN " . DB_PREFIX . "option_value_description ovd ON (pov.option_value_id = ovd.option_value_id)";       
        // - - - - - - - - - - - - -

查找第70行：

$implode[] = "LCASE(pd.name) LIKE '%" . $this->db->escape(utf8_strtolower($word)) . "%'";

将其更改为：

$implode[] = "LCASE(pd.name) LIKE '%" . $this->db->escape(utf8_strtolower($word)) . "%'
OR LCASE(ovd.name) LIKE '%" . $this->db->escape(utf8_strtolower($word)) . "%'";

现在搜索将“看到”产品选项值名称，如“大”，“红色”等。

要搜索价格要容易得多，只需在WHERE子句中包含参数即可完全匹配使用：

"pd.price = '" . $this->db->escape(utf8_strtolower($word)) . "'

for，比方说，价格值达到一定值，使用：

"pd.price <= '" . $this->db->escape(utf8_strtolower($word)) . "'

希望，你明白了。

现在，这只是一个快速而又肮脏的例子，旨在让您前进。

我不是提出这个作为最终解决方案。

您需要考虑添加新的GET变量来控制是否在搜索中包含选项和/或价格。此外，搜索价格范围而不是价格。添加变量来控制是否使用AND或OR运算符 - 即查找'red'和'XL'或两者中的任何一个。

祝你好运。
