所以我有这个注册脚本:

HTML:

<form action="register.php" method="POST">
    <label>Username:</label> <input type="text" name="username" /><br />
    <label>Password:</label> <input type="text" name="password" /><br />

    <label>Gender:</label>
    <select name="gender">
      <optgroup label="genderset">
        <option value="Male">Male</option>
        <option value="Female">Female</option>
        <option value="Hermaphrodite">Hermaphrodite</option>
        <option value="Not Sure!!!">Not Sure!!!</option>
      </optgroup>
    </select><br />
<input type="submit" value="Register" />
</form>

PHP/SQL:

<?php

$username = $_POST['username'];
$password = $_POST['password'];
$gender = $_POST['gender'];

mysql_query("INSERT INTO registration_info (username, password, gender) VALUES ('$username', '$password', '$gender')
")  

?>

问题是,用户名和密码插入"registration_info"表就好了.但是,选择下拉菜单中的性别输入不会.有人可以告诉我如何解决这个问题,谢谢.
