Question

以下代码功能正常，我可以在数据库的表中添加一行。但是，当我运行它时，我会在页面上收到通知

注意：未定义的索引：在第49行的C：\ xampp \ htdocs \ PHP_RESUME_AD \ php \ ED_A.php中提交

我不确定为什么。

<html id="education" lang = "en-US">
    <head>
     <link rel="stylesheet" type="text/css" href="../css/index.css">
 <meta charset = "UTF-8">
 <title>Education</title>
 <style type = "text/css">
  table, th, td {border: 1px solid black};
 </style>
 </head>
    <body>
        <form method="post">
            Enter your Class<input type="text" name="Class"><br>
            Enter your Discipline<input type="text" name="Discipline"><br>
            Enter your Description<input type="text" name="Description"><br>
            Enter your Term<input type="text" name="Term"><br>


            <input type="submit" name="submit" value="Save">
        </form>

        <style>
ul {
list-style-type: none;
margin: 0;
padding: 0;
}

li {
display: inline;
}
</style>
<body>

 <ul
  <li><a href="../html/welcome.html">Back to Home page</a></li>
  <li><a href="../php/ED_D.php">Education </a></li>
  <li><a href="../php/SK_D.php">Skills</a></li>
  <li><a href="../php/SK_A.php">Skills Add</a></li>
  <li><a href="../php/HB_D.php">Hobbies</a></li>
  <li><a href="../php/HB_A.php">Hobbies Add</a></li>
  <li><a href="../php/PWE_D.php">Work Experience</a></li>
  <li><a href="../php/PWE_A.php">Work Experience Add  </a></li>
  <li><a href="../php/email.php">Contact Me!</a></li>
</ul>
    </body>
</html>

<?php
   if(!empty($_POST["submit"]=="Save"))
   {
       $Class = $_POST["Class"];
       $Discipline = $_POST["Discipline"];
       $Description = $_POST["Description"];
       $Term = $_POST["Term"];

       mysql_connect("localhost", "root", "HAPPY3");
       mysql_select_db("cs266ad_db1");

       $s="insert into education(Class,Discipline,Description,Term)   values('".$Class."','".$Discipline."','".$Description."','".$Term."')";

       mysql_query($s);
   }
   ?>

php mysql添加代码工作...注意：未定义的索引
