我尝试过这个代码，侧！尝试utf8编码您的文本，表单输入名称等...
< input type ='text'name = '名称' >

$ myemail =tresorunikin@gmail.com;
$ name = check_input（$ _ POST ['name']，输入你的名字）;
$ company = check_input（$ _ POST ['company']，输入您的公司名称）;

$ address = check_input（$ _ POST ['address']，输入你的地址）;

$ number = check_input（$ _ POST ['number']，输入你的号码）;
$ mobile = check_input（$ _ POST ['mobile']，输入您的手机号码）;
$ email = check_input（$ _ POST ['email']，输入有效的电子邮件地址）;
$ client = check_input（$ _ POST ['client']，你是客户吗？请让我们知道）;
$ method = check_input（$ _ POST ['method']，选择您喜欢的联系方式）;
$ message = check_input（$ _ POST ['message']，输入您的评论或描述）;
$ date = check_input（$ _ POST ['date']，告诉我们您的活动何时发生）;

I'm pretty new to form validation and processing, in fact, this is my first attempt, and I've created a simple contact form with required text fields, comments text area and two radio buttons. I've gone through many basic tuts and have put together script using PHP. The problem I have is that when i click submit if the form is unfilled, I am directed to a new page that has an error message saying i need to fill in my name. But if I fill in my name and click submit, I get the same message instead of the error message specified for the next field. I even get that message when all fields are filed in. Here is my code:
<?php
$myemail = "ysjostar072@gmail.com";
$name = check_input($_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( "ysjostar072@gmail.com", "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!

mail($myemail, $subject, $enquiry);

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)
{
?>

<body>

<?php echo $myError; ?>
</body>
</html>
<?php
exit();
}
?>
Please help me out. I don't know what I'm doing wrong. Thanks in advance :)

解决方案
I've tried this code and it works on my side! try to utf8 encode your text, the form inputs name and so on...
<input type='text' name='name'>
<?php
$myemail = "tresorunikin@gmail.com";
$name = check_input($_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( "ysjostar072@gmail.com", "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!

mail($myemail, $subject, $enquiry);

exit();
function check_input($data, $problem='')

if (strlen($data) == 0)
{

}
$data = stripslashes($data);

return $data;
}
function show_error($myError)
{
