在我编写的代码中，我在135-154行得到了多个未定义的索引错误...我很确定我已经在第125-130行定义了必要的变量。我已经检查了与此问题有关的其他问题，但我找不到任何相关信息。任何人都可以解释为什么我仍然得到这个错误，即使我定义了这些变量？非常感谢任何帮助。
编辑：我得到的错误信息是：注意：未定义的索引： 第133行的C：\ xamppnew \ htdocs \ loginSignup \ teachersPage.php中的语法
注意：未定义的索引：读入 第134行的C：\ xamppnew \ htdocs \ loginSignup \ teachersPage.php

答案 0 :(得分：0)
您的问题是使用非存在变量。
Ex：135-140行
$ _ POST不存在于initial =＆gt;未定义的错误
修改代码如下： 在将其设置为值
之前确保变量存在$_SESSION["grammar"] = isset($_POST["grammar"]) ? $_POST["grammar"] : '';
