Question

我正在开展一个学校项目，当我试图创建一个具有注册功能的网站时，我在提交表单后会显示此错误：

Answer 1

尝试更改此内容：

bind_param("ssssssii", $username, $password, $tpnumber, $gender, $group, $email, $phoneCode, $phone);

到此：

bind_param($username, $password, $tpnumber, $gender, $group, $email, $phoneCode, $phone);

Answer 2

首先，希望您正在按预期通过XAMPP运行该程序。

通常，由于与数据库关联的代码而发生此问题

也许您在phpmyadmin中创建的列名与您要触发的列名不同，也许错误会与columnNames或tableName的拼写一样少，

尝试检查相同内容或进行一些调整。
