Question

我是php新手。我想在php mysql中登录和注册。为此，我创建一个简单的表单，并测试数据是否插入phpmyadmin。这些值不会保存在db中。我不知道错误在哪里。我已经在下面添加了编码

MY Db连接：

<?php

  $connect = mysql_connect("localhost", "root", "") or die("Unable to connect database".mysql_error());

  mysql_select_db("logindb", $connect) or die ("sorry db connection fail");
?>

我的注册表格：

<?php
include("config.php");
?>
<!DOCTYPE html>
<html>
<head>
    <title>Login screen</title>
    <style type="text/css">
    .register-form{
        width: 500px;
        margin: 0 auto;
        text-align: center;
        padding: 10px;
        padding: 10px;
        background : #c4c4c4;
        border-radius: 10px;
        -webkit-border-radius:10px;
        -moz-border-radius:10px;
    }
    .register-form form input{padding: 5px;}
    .register-form .btn{
        background: #726E6E;
        padding: 7px;
        border-radius: 5px;
        text-decoration: none;
        width: 50px;
        display: inline-block;
        color: #FFF;
    }
    .register-form .register{
        border: 0;
        width: 60px;
        padding: 8px;
    }
    </style>
</head>
<body>
<?php
if(isset($_POST['submit']))
{
$name=mysql_real_escape_string($_POST['username']);
$email=mysql_real_escape_string($_POST['email']);
$password=mysql_real_escape_string($_POST['password']);
$cpassword=mysql_real_escape_string($_POST['confirmpassword']);
$query = mysql_query("inser into register values('', '$name', '$email', '$password',   '$cpassword')");
if($query)
{
    header("location:success.php");
}
}

?>
    <div class="register-form">
        <h1>Register</h1>
        <form action="" method="post">
            <p><label>User Name: </label>
            <input type="text" id="username" name="username" placeholder="Username">
            </p>
            <p><label>E-Mail&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; :</label>
            <input id="email" name="email" type="email">
            </p>
            <p><label>Password&nbsp;&nbsp; :</label>
            <input id="password" name="password" type="password">
            </p>
            <p><label>confirm Password &nbsp;&nbsp; :</label>
            <input id="confirmpassword" name="confirmpassword" type="password">
            </p>
            <input type="submit" name="submit" value="register" class="btn register">
            <a class="btn" href="login.php">Login</a>
        </form>
    </div>
</body>
</html>

在创建新页面成功后，我重定向到success.php

<!DOCTYPE html>
<html>
<head>
    <title>success full</title>
</head>
<body>
    <h1>Successfully registered</h1>
</body>
</html>

输入数据后，我点击提交。我是回声并看到了SQL查询，我正在获得价值，但它没有保存在phpmyadmin数据库中。我是php的新手，请帮我开发更多的php。我再次感谢你。

Answer 1

除非必要，否则请在任何HTML之前保留PHP。另外，在查询中指定列，因为空字符串可能导致查询失败您真的需要将确认密码存储在数据库中吗？我不相信你这样做，并确保你哈希。确认数据库中的所有列都与您要插入的内容相匹配。

<?php
include("config.php");

if(isset($_POST['submit'])) {
    $name=mysql_real_escape_string($_POST['username']);
    $email=mysql_real_escape_string($_POST['email']);
    $password=mysql_real_escape_string($_POST['password']);
    $cpassword=mysql_real_escape_string($_POST['confirmpassword']);
    $query = mysql_query("INSERT INTO register
                          (name_column,email_column,password_column)
                          VALUES('".$name."', '".$email."', '".$password."')");
    if($query) {
        header("location:success.php");
    }

} else {
    echo "no form data received.";
}

?>
<!DOCTYPE html>
//HTML HERE//

Answer 2

更改

$query = mysql_query("insert into register values('', '$name', '$email', '$password', '$cpassword')");

和

// Specify the last parameter to the DB NAME! $connect = mysql_connect("localhost", "root", "logindb")

删除

mysql_select_db("logindb", $connect) or die ("sorry db connection fail");

Answer 3

insert into register values('', '".$name."', '".$email."', '".$password."','".$cpassword."')

插入的数据未保存在phpmyadmin数据库中
