“更新注册SET profilepicture = $ target_path WHERE uname='[email protected]'limit 1”;这给了我和error :: UPDATE注册错误SET profilepicture = images/Jellyfish.jpg WHERE uname='[email protected]'限制1 =='未知列'图像'在'字段列表'@Jens – 2014-11-06 12:40:19
@namrata已更新我的答案。你必须在'$ target_path'周围加引号,因为它是一个char字段。 – Jens 2014-11-06 12:42:32
