我正在开发表单和表单处理程序。方法是_POST，我使用PHP处理它。现在，当我想处理表单时，它说 $username 未定义。
我的表格:
<html>
<head>
<title>Register</title>
<script type="text/javascript" src="includes/register_form_validator.js" ></script>
</head>
<body>
<form method="post" action="includes/register_form_handler.php" name="register_form" >
<label for="username" >Username :</label><input placeholder="username" type="text" /><br>
<label for="password">Password :</label><input type="password" name="password" /><br>
<label for="cpassword">Confirm Password :</label><input type="password" name="cpassword" /><br>
<label for="email">E-Mail :</label><input type="email" name="email" onChange="" /><br>
<input type="submit" value="Submit" />
</form>
</body>
</html>
处理程序:
<?php
// Do a Form Validation , Makes sure that resource is Valid///////////
$actual_link = "http://$_SERVER[HTTP_HOST]" . "/dcreview/register.php";
if (!isset($_SERVER['HTTP_REFERER'])) {
echo "Invalid Form";
exit;
} else {
if ($_SERVER['HTTP_REFERER'] != $actual_link) {
echo "Invalid Form";
exit;
}
}
///////////////////////////////////////////////////////////////////
// Processes Form //
$user = $_POST["username"];
$pass = $_POST['password'];
$email = $_POST['email'];
password_hash($pass, PASSWORD_BCRYPT);
?>
最佳答案
用此行替换您的用户名 HTML
<label for="username" >Username :</label><input name="username" placeholder="username" type="text" /><br>
