【问题描述】:
这里的 PHP 和 MYSQL 新手......现在真的可以使用您的帮助。我在我的脚本中实现了一个 Submodal,最后让它将“用户注释”提交到数据库中。不幸的是,每次新提交时,提交的文本都会覆盖之前提交的文本。有人告诉我使用 CONCAT_WS 来防止这种情况发生......我已经在 Dreamweaver 上尝试了几个小时来实现这一点,但它不起作用。这是我该部分的代码...
出现此错误的新代码:
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 'great'')
WHERE Id=35' at line 1
代码...
