好的我是php的新手，我制作了这个脚本
<?php
include ('abcd.php');
echo '<html>
<head>
<title>Amul Eazy Registration</title>
<style type="text/css">
body {
background-color: #22274f;
text-align: center;
}
div.main {
text-align: center;
padding-left: 400px;
}
div.block {
text-align: center;
height: 250px;
width: 468px;
background-color: #14193c;
color: white;
font-family: Tahoma, Geneva, sans-serif;
font-size: 20px;
font-weight: 400;
padding-top: 40px;
}
div {
margin: 10px;
padding-bottom: 10px;
width: 300px;
padding-left: 50px;
}
.title {
float: left;
width: 140px;
text-align: left;
padding-right: 10px;
}
div.header {
height: 50px;
padding-left: 150px;
padding-top: 30px;
}
div.logo {
height: 44px;
width: 199px;
background-image: url("image.png");
background-repeat: no-repeat;
}
div.credits {
height: 100px;
padding-left: 50px;
}
div.image {
float: right;
}
div.captcha{
background-image: url("'.$path.'");
background-repeat: no-repeat;
}
p.cred {
font-size: 30px;
color: #0083aa;
font-family: Georgia, Times, serif;
text-shadow: 2px 2px 7px #111111;
}
input[type=submit] {

background: url("create-account-button.png") no-repeat scroll 0% 0% transparent;
border: 0px none;

font-family: "AccordAlternateBold";

input[type=submit]:hover {

</style>
</head>
<body>
<div class="main">
<center>
<div class="header">
<div class="logo"></div>
</div>
<form action="main.php" method="post">
<div class="block">
<div >
<label for="mn" class="title">Mobile Number</label>
<input type="text" id="mn" name="mn" />
</div>
<div >
<label for="ped" class="title">Password</label>
<input type="text" id="pwd" name="pwd" />
</div>
<div >
<label for="email" class="title">Email</label>
<input type="text" id="email" name="email" />
</div>
<div>
<div class="captcha">
<input type="text" id="cap" name="cap" />
</div>
</div>
<div>
<input type="submit" name="submit" value="submit" />
</div>
</div>
</form>
<div class="credits">
<div class="ll">
<p class="cred">By</p>
<p class="cred">TH3 Undefined variable</p>
</div>
</div>
</center>
</div>
</body>
</html>';
?>
这是显示表单
的主页面这是main.php
形式的动作 <?php
if (isset($_POST['mn'])) $number = $_POST['mn'];
else $number = "(Not entered)";
if (isset($_POST['pwd'])) $pass = $_POST['pwd'];
else $pass = "(Not entered)";
if (isset($_POST['email'])) $mail = $_POST['email'];
else $mail = "(Not entered)";
if (isset($_POST['cap'])) $capt = $_POST['cap'];
else $cap = "(Not entered)";
echo $number;
echo $pass;
echo $mail;
echo $capt;
echo 'Hello';
?>
所以问题是在填写表单并按下提交按钮后没有任何反应。仅显示空白页面。我添加了echo＆＃39; Hello World＆＃39 ;;但这甚至没有回应。尝试了我能想到的所有可能的故障排除，但似乎没有任何效果。有谁能告诉我这是什么问题。
由于
未定义的变量
