单击opencart上的标记时SQL语法错误是什么？

Question

点击我的Opencart 2.3.0.2商店产品页面上的标签时出现此错误

PHP Fatal error:  Uncaught exception 'Exception' with message 'Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'OR man.name LIKE '%%' pd.tag LIKE '%conjunto%' AND pd.tag LIKE '%infantil%' AND ' at line 1<br />Error No: 1064<br />SELECT p.product_id, (SELECT AVG(rating) AS total FROM oc_review r1 WHERE r1.product_id = p.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating, (SELECT price FROM oc_product_discount pd2 WHERE pd2.product_id = p.product_id AND pd2.customer_group_id = '1' 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 oc_product_special ps WHERE ps.product_id = p.product_id AND ps.customer_group_id = '1' 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.priori in C:\inetpub\wwwroot\cabanins\system\library\db\mysqli.php on line 40

我不知道这个错误的原因是因为我的localhost版本正常工作。

Answer 1

你的问题就在这里：

man.name LIKE '%%' pd.tag

您需要包含这样的AND标记

man.name LIKE '%%' AND pd.tag

虽然没有理由

man.name LIKE '%%'

因为%%将匹配一切。

所以你可以做到：

OR pd.tag LIKE '%conjunto%' 

Answer 2

谢谢你的帮助。我不明白为什么代码只有在线版本错误，并在localhost上正常工作。我使用相同的代码。那是代码
