Question

嘿，我正在处理一个简单的注册表单，我已经对它进行了简单的测试。基本上我说如果用户名归档是空的，我们点击提交它将回显'所有提交的都是必需的'否则确定。我的代码看起来很好，否则我会疯了可以有人看看我谢谢你:)

代码：

<?php

  //require 'core.inc.php';



if(isset($_POST['username'])&& isset($_POST['password']) && isset($_POST['passwordAgain'])&& isset($_POST['Firstname'])&& isset($_POST['Lastname'])){

    $username = $_POST['username'];
    $password = $_POST['password'];
    $password_again = $_POST['passwordAgain'];
    $Firstname = $_POST['Firstname'];
    $Lastname = $_POST['Lastname'];

    if(!empty($username)){

        echo 'OK.';

    }else{

   echo 'fill in all details thank you';
     }


}

?>


<form action="join.inc.php" method="POST">


    Username: <input type="text" name="username" /><br />
    Password: <input type="password" type="password" /><br />
    Password Again: <input type="password" type="passwordAgain" /><br />
    FirstName: <input type="text" name ="Firstname"/><br />
    LastName: <input type="text" name ="Lastname" /><br />
    <input type="submit" value="SUBMIT" />
</form>

Answer 1

纠正这个：

 Password: <input type="password" name="password" /><br />
 Password Again: <input type="password" name="passwordAgain" /><br />

Answer 2

您的问题出在您的HTML中：

Password: <input type="password" type="password" /><br />
Password Again: <input type="password" type="passwordAgain" /><br />

您指定的是两次类型字段，而不是名称字段。

Answer 3

如何为提交按钮命名并尝试这样：

<input type="submit" name="sbmtBtn" value="SUBMIT" />

并提交部分：

if(isset($_POST['sbmtBtn']))
{

$username = $_POST['username'];
$password = $_POST['password'];
$password_again = $_POST['passwordAgain'];
$Firstname = $_POST['Firstname'];
$Lastname = $_POST['Lastname'];

if($username && $password && $password_again && $Firstname && $Lastname))
{

    echo 'OK.';

}
else
{

    echo 'all fields are required.';
}


}

这个PHP脚本有什么问题
