我是非常新的表单验证和处理，事实上，这是我的第一次尝试，并且我创建了一个包含所需文本字段，注释文本区域的简单联系表单和两个单选按钮。我已经经历了许多基本的工作，并且使用PHP将脚本放在一起。我遇到的问题是，当我单击提交如果窗体是空的，我被导向到一个新的页面，有一个错误消息说我需要填写我的名字。但是，如果填写我的姓名并点击提交，我会得到相同的消息，而不是为下一个字段指定的错误消息。我甚至在收到所有字段时都会收到此消息。以下是我的代码：表单错误信息无法正常工作，表单不会提交
<?php
$myemail = "[email protected]";
$name = check_input($_POST['name'], "Enter your name");
$company = check_input($_POST['company'], "Enter your company name");
$function = check_input($_POST['function'], "Provide an occassion");
$address = check_input($_POST['address'], "Enter your address");
$place = check_input($_POST['place'], "Enter your area code");
$number = check_input($_POST['number'], "Enter your number");
$mobile = check_input($_POST['mobile'], "Enter your mobile number");
$email = check_input($_POST['email'], "Enter a valid E-Mail address");
$client = check_input($_POST['client'], "Are you a client already? Please let us know");
$method = check_input($_POST['method'], "Choose your preferred method of contact");
$message = check_input($_POST['message'], "Enter your comments or description");
$date = check_input($_POST['date'], "Tell us when your event takes place");
$size = check_input($_POST['size'], "Tell us how big your presentation is going to be");
$subject = "Client from website";
$subject = striplashes($subject);
if(isset($_POST['button-submit'])) {
if (!isset($_REQUEST['email'])) {
header("Location: index.html");
}
else {
mail("[email protected]", "Feedback Form Results",
$message, "From: $email");
header("Location: thanks.html");
}
}
if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/", $email))
{
show_error("E-mail address not valid");
}
$enquiry = "Hello!
Your contact form has been submitted by:
Name: $name

Contact number: $number

End of message";
mail($myemail, $subject, $enquiry);
header('Location: thanks.html');
exit();
function check_input($data, $problem='')
{
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
if ($problem && strlen($data) == 0)
{
show_error($problem);
}
return $data;
}
function show_error($myError)
{
?>
<html>
<body>
<b>Please correct the following error:</b><br />
<?php echo $myError; ?>
</body>
</html>
<?php
exit();
}
?>
请帮我解决。我不知道我做错了什么。感谢提前:)
下面是HTML表单：

</ul>
</form>
如何调用check_input函数，我认为我们在这里丢失了一些代码。 – RageZ 2011-12-22 09:33:03
