php - 尝试了未定义索引的解决方案，但由于相同的错误而失败

Question

我正在尝试解决<mail>未发送的错误。长话短说 - 我已将此错误处理程序添加到联系表单中。它报告以下内容：-

E_NOTICE 第 72 行的“EmailScript.php”文件中的错误：未定义的索引：操作错误出现在第 66 行，但我添加了我认为的解决方案：- 第 65 行到第 70 行。我也尝试同时给出$_request 和 $action 空数组“foo bar”值，以及其他尝试的解决方案。

这超出了我的理解伙计们，有没有一些提示的机会？

但是现在我在填写表格时根本没有收到错误 - 它正在加载一个空白页面。从我阅读的内容来看，虽然不要假装完全理解，但这是某种类型的服务器问题。显然安装 Xamp 可以修复它，但我的服务器是树莓派，所以没有 Xamp 只有 LAMP。明天我将再次开始，伙计们漫长的一天感谢助攻。
