这是我的注册页面，表单中的信息会添加到数据库中。

<?php 
$con = mysql_connect("localhost","root",""); 
if (!$con) 
  { 
  die('Could not connect: ' . mysql_error()); 
  } 


mysql_select_db("favnet", $con); 

extract($_POST); 

$sql="INSERT INTO membership (FirstName,LastName,Age,Email,Username,Nickname,TV,Movie,Book) VALUES ('$fname','$lname','$age','$email','$username','$nname','$tv','$movie','$book')";

// Execute query 
if(mysql_query($sql,$con) === false) 
{ 
   echo mysql_error() . "<br />$sql"; 
}  

mysql_close($con); 
print "Record Added"; 
?>

我不知道我做错了什么，有人可以帮忙吗？

Answer 1

将value分配给option作为

    <select align="right" class="select" name="tv">
        <option value="favourite show">Favorite TV Show</option>
         ...
    </select>

Answer 2

通过表单提交select（下拉）数据时，所有标签都需要一个值属性，该属性将通过POST发送。像电影一样为电影和电视选项添加值属性。

将下拉列表数据添加到MySQL数据库中
