在sql数据库中输入用户输入？

Question

我正在尝试创建一个注册表单,但我无法将用户的电子邮件发送到sql数据库.

这是我的HTML表单代码

<form class="form-login" action="register.php" method="POST">
    <h2 class="form-login-heading">sign up now</h2>
    <div class="login-wrap">
        <input type="text" class="form-control" placeholder="First Name" name="first" autofocus>
        <br>
        <input type="text" class="form-control" placeholder="Last Name" name="last">
        <br>
        <input type="text" class="form-control" placeholder="Email" name="email">
        <br>
        <input type="text" class="form-control" placeholder="Username" name="username">
        <br>
        <input type="password" class="form-control" placeholder="Password" name="password">
        <label class="checkbox">
            <span class="pull-right">
                <a href="resetpassword.html"> Forgot Password?</a>

            </span>
        </label>
        <button class="btn btn-theme btn-block" type="submit"><i class="fa fa-lock"></i> SIGN UP</button>
        <hr>

        <div class="login-social-link centered">
            <p>or you can sign in via your social network</p>
            <button class="btn btn-facebook" type="submit"><i class="fa fa-facebook"></i> Facebook</button>
            <button class="btn btn-twitter" type="submit"><i class="fa fa-twitter"></i> Twitter</button>
        </div>
        <div class="registration">
            Don't have an account yet?<br/>
            <a class="" href="#">
                Create an account
            </a>
        </div>

    </div>

    <!-- Modal -->
    <div aria-hidden="true" aria-labelledby="myModalLabel" role="dialog" tabindex="-1" id="myModal" class="modal fade">
        <div class="modal-dialog">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                    <h4 class="modal-title">Forgot Password ?</h4>
                </div>
                <div class="modal-body">
                    <p>Enter your e-mail address below to reset your password.</p>
                    <input type="text" name="email" placeholder="Email" autocomplete="off" class="form-control placeholder-no-fix">

                </div>
                <div class="modal-footer">
                    <button data-dismiss="modal" class="btn btn-default" type="button">Cancel</button>
                    <button class="btn btn-theme" type="button">Submit</button>
                </div>
            </div>
        </div>
    </div>
    <!-- modal -->

</form>

这是我正在使用的PHP代码,以下php代码只能插入名字,姓氏,用户名和密码,但电子邮件被遗漏了.我在另一个表单上尝试了相同的PHP代码,这似乎工作正常.有人能解释我哪里错了吗？

$first = $_POST['first'];
$last = $_POST['last'];
$email = $_POST['email'];
$username = $_POST['username'];
$password = $_POST['password'];

以下是我的sql代码,用于将数据插入数据库,其余代码建立连接,一切似乎都正常.那么有人能告诉我哪里出错了吗？

$sql = "INSERT INTO registeredusers (FirstName,LastName,UserName,Email,Password) 
VALUES ('$first','$last','$username_lower','$email','$encryptedPWD')";

这是sql结构

CREATE TABLE 'registeredusers' (
    'id' int(11) NOT NULL,
    'FirstName' varchar(50) NOT NULL,
    'LastName' varchar(50) NOT NULL,
    'UserName' varchar(50) NOT NULL,
    'Email' varchar(50) NOT NULL,
    'Password' varchar(255) NOT NULL,
    'ResetPassword' int(7) DEFAULT NULL,
    'friends' int(255) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

我看到你name="email"在单个form标签内有2个输入(在注册表单和忘记密码表单中).这是唯一的原因.

作为建议,您应该使用单独的表单标记或使用不同的email输入名称.
