我是php的新手，我创建了一个用户注册表单。但是每当我提交表单时，页面的一部分无法加载。我看到了"成功注册"消息，但没有看到右侧栏、页脚或包装器div。在搜索了一整天的互联网后，我得出结论，这是exit()函数。但是，如果我在退出函数中离开并提交表单，我的所有页面都会加载，但是原始注册表单仍然显示在"成功注册"消息的下面。有人能帮帮我吗?

您不需要exit()，只需要if ... else块:
if ((/* form submitted */) && (/* everything is OK */))
{
// do stuff
}
else
{
// show form
}
有两种解决方案。
- 您可以在提交时将表单重定向到另一个包含表单处理和感谢信息的逻辑页面。
- 您可以将初始表单和感谢消息/处理包装在有条件的if块中，以确定要显示哪些内容。
