我正在尝试创建一个简单的 PHP 注册和登录表单。在向 register.php 文件添加样式和 HTML 之前，一切都按预期工作。现在，当单击注册时，没有说谢谢您注册，没有任何反应。

    <html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<div id="wrapper">
<div class="form">

<?php
echo "<h1>Register</h1>";

$submit = $_POST['submit'];

// form data

$fullname = STRIP_TAGS($_POST['fullname']);
$username = STRIP_TAGS($_POST['username']);
$password = STRIP_TAGS($_POST['password']);
$repeatpassword = STRIP_TAGS($_POST['repeatpassword']);
$date = date("Y-m-d");

if ($submit)
{   
    if($fullname&&$username&&password&&$repeatpassword)
    {


    if ($password==$repeatpassword)
    {
        //check char length of username and fullname
        if(strlen($username)>25||strlen($fullname)>25)
        {
            echo "Length of username or fullname is too long!";
        }
        else
        {   //check password length

            if (strlen($password)>25||strlen($password)<6)
            {
            echo "Password must be between 6 and 25 characters";
            }
            else 
            {   //register the user!
                // encrypt password
            $password = md5($password);
            $repeatpassword = md5($repeatpassword);

                //open database

            $connect = mysql_connect("localhost", "Matt", "password123");
            mysql_select_db("phpsignin");

            $queryreg = mysql_query("
            INSERT INTO users VALUES ('','$fullname','$username','$password','$date')`

            ");

            die ("Thankyou for registering! <a href='index.php'> Return to login page</a>");
            }
        }


    }   
    else
        echo "Your passwords do not match!";
    }
    else
        echo "Please fill in <b>all</b> fields!";

}

?>
<form id="login" action='register.php' method='POST'>
    <fieldset>
            <ol>
            <li>
            <label>Your Full Name:
            <input type="text" name='fullname' value='<?php echo $fullname; ?>'>
            </label>
            </li>

            <li>
            <label>Choose a username:
            <input type="text" name='username' value='<?php echo $username;?>'>
            </label>
            </li>

            <li>
            <label>Choose a password:
            <input type="password" name='password'>
            </label>
            </li>

            <li>
            <label>Confirm Your Password:
            <input type="password" name='repeatpassword'>
            </label>
            </li>
    </fieldset>
    <div id="buttonHolder">
    <button type="submit" name="submit">Register</button>
    </div>
</form>

</div>
</div>

您的提交按钮没有value，因此if ($submit)永远不会是真正的值，并且您的逻辑分支将永远不会运行。

改变：

$submit = $_POST['submit'];

到：

$submit = $_POST;
