我尝试在我的网站上实现以下代码，但是出现了这个错误：
致命错误：未捕获的异常'PDOException'，消息'SQLSTATE [42S22]：未找到列：1054 /home/multive2/public_html/superdonate/ajax/login.php中的'字段列表'中的未知列'usertype' ：63堆栈跟踪：＃0 /home/multive2/public_html/superdonate/ajax/login.php(63）：PDOStatement-＆gt;执行（数组）#main {main}抛出/ home / multive2 / public_html / superdonate / ajax /login.php在第63行“
为什么会这样？ 对不起我的英文/代码。

发布为社区维基。 （不应该有代表）。
错误很明显，usertype列不存在。
您可以创建它，也可以将其从查询中删除。

尝试在包含值usertype的引号（'$ variable'）中编写变量。
