突然间我的 php 代码出现了:

注意:索引未定义:在C:\xampp\htdocs\globalautoparts\register.php第36行提交

注意:C:\xampp\htdocs\globalautoparts\register.php 第40行未定义索引:fullname

注意:Undefined index: username in C:\xampp\htdocs\globalautoparts\register.php on line 41

注意:C:\xampp\htdocs\globalautoparts\register.php 第42行未定义索引:密码

注意:Undefined index: repeatpassword in C:\xampp\htdocs\globalautoparts\register.php on line 43

注意:未定义索引:C:\xampp\htdocs\globalautoparts\register.php 第45行中的email

在注册页面上。

我该如何解决？

这是我的代码:
