Question

我在http://www.kaimeramedia.com/derek/Website/contact.php有一个联系表单。我在PHPcodechecker.com上检查了我的PHP代码，它说没有语法错误。我认为开始代码是在一些庄园工作，因为每次我按下提交它都会进入下一个验证我留下的位置：“检测到不正确的电子邮件地址。请点击浏览器后退按钮再试一次”。

我只是想知道我是否应该以不同方式编写代码以确保电子邮件验证通过并允许提交消息。我不确定我是否有向后编码的东西。我尝试了很多组合，但是现在这是我没有mailform.php错误的最远的。 mailform.php文件的代码是：

 <?php 
     session_start();
     $dontsendemail = 0;
     $possiblespam = FALSE;
     $strlenmessage = "";
     $email = $_REQUEST['email']; 
     $name = $_REQUEST['name']; 
     $message = $_REQUEST['message']; 
     $subject = "Regarding Your Portfolio";$emailaddress = "me@website.com"; 

     // checks if name field is empty
     function checkname() {
if (empty($name)) {
    die ("You did not enter your name.  Please hit your browser back button and try again.");
return 1;
            }
        }

// checks if the captcha is input correctly
function checkcaptcha() {
            if ($_SESSION["pass"] != $_POST["userpass"]) {
                die("Sorry, you failed the CAPTCHA. Note that the CAPTCHA is case-sensitive. Please hit your browser back button and try again.");
                return 1;
            }
        }

// checks proper syntax 
function checkemail() {
    if(preg_match("/^([a-zA-Z0-9])+([a-zA-Z0-9\._-])*@([a-zA-Z0-9_-])+([a-zA-Z0-9\._-]+)+$/", $email));
    else{
        die("Improper email address detected. Please hit your browser back button and try again."); 
        return 1;
    }
}


function spamcheck($field) {
    if(eregi("to:",$field) || eregi("cc:",$field) || eregi("\r",$field) || eregi("\n",$field) || eregi("%0A",$field)){ 
        $possiblespam = TRUE;
    }else $possiblespam = FALSE;
    if ($possiblespam) {
        die("Possible spam attempt detected. If this is not the case, please edit the content of the contact form and try again.");
        return 1;
    }
}
function strlencheck($field,$minlength,$whichfieldresponse) {
    if (strlen($field) < $minlength){
        die($whichfieldresponse); 
        return 1;
    }



}

        if ($dontsendemail == 0) $dontsendemail = checkcaptcha($email);

if ($dontsendemail == 0) $dontsendemail = checkemail($email);
if ($dontsendemail == 0) $dontsendemail = spamcheck($email);
if ($dontsendemail == 0) $dontsendemail = spamcheck($name);
if ($dontsendemail == 0) $dontsendemail = strlencheck($email,10,"The email address field is too short. Please hit your browser back button and check your entry.<br />");
if ($dontsendemail == 0) $dontsendemail = strlencheck($message,10,"The message field is too short. Please hit your browser back button and check your entry.<br />");
if ($dontsendemail == 0) $dontsendemail = strlencheck($emailaddress,8,"You have not selected a recipient of your message. Please hit your browser back button and check your entry.<br />");
if ($dontsendemail == 0) $dontsendemail = strlencheck($name,3,"The Name field is too short. Please hit your browser back button and check your entry.<br />");
if ($dontsendemail == 0) {mail($emailaddress,"Subject: $subject",$message,"From: $name,$email" ); include "thankyou.php";}
?>

我在这段代码中放了一个虚拟邮件，但真正的邮件是在mailform.php文件中如果有人能看到我出错的地方，我将非常感激。

根据我之前的回答，我全力以赴并清理了你的剧本。我的手上显然有太多时间。没有检查它是否有效。古德勒克！

<?PHP
session_start();
try{
    $check = new check();
    if(!isset($_REQUEST['Email']))
        throw new exception('You did not enter an email address.');

    if(!isset($_REQUEST['message']))
        throw new exception('You did not enter a message.');

    if(!isset($_REQUEST['Name']))
        throw new exception('You did not enter a name');

    $sender = $_REQUEST['Email'];
    $message = $_REQUEST['message'];
    $name = $_REQUEST['Name'];
    $recipient = 'test@test.com';

    $subject = 'Regarding Your Portfolio';

    if($check->captcha('userpass') == FALSE)
        throw new exception('Your captcha is incorrect.');

    if($check->spam($sender) == FALSE)
        throw new exception('Your email field contains spam.');

    if($check->spam($name) == FALSE)
        throw new exception('Your name field contains spam.');

    if($check->length($sender, 10) == FALSE)
        throw new exception('Your email field does not satisfy the minimum character count.');

    if($check->length($message, 8) == FALSE)
        throw new exception('Your message field does not satisfy the minimum character count.');

    if($check->length($name, 3) == FALSE)
        throw new exception('Your name field does not satisfy the minimum character count.');

    mail($recipient, $subject, $message, "From: $name <$sender>" );
    include "thankyou.php";
}catch (Exception $E){
    die($E->getMessage());
}




class check{

    function captcha($field){
        if(isset($_REQUEST[$field])==FALSE){ return false; }
        if($_SESSION['pass'] != $_REQUEST[$field]){ return false; }
        return true;
    }

    function email($email){
        if(!filter_var($email, FILTER_VALIDATE_EMAIL)){ return false;}
        return true;
    }

    function spam($field){
        if(eregi("to:",$field) || eregi("cc:",$field) || eregi("\r",$field) || eregi("\n",$field) || eregi("%0A",$field)){ return false; }
        return true;
    }

    function length($field, $min){
        if(strlen($field) < $min){ return false; }
        return true;
    }
}

您的脚本存在两个问题。

您没有在$ email参数中解析。你忘了把它包括在内。
电子邮件的正则表达式非常挑剔，并不总是包含所有标准。

<强>解决方案：从PHP5开始，您可以使用以下内容验证电子邮件，或者如果您想使用正则表达式，只需添加$ email参数。

function checkemail($email) {
    if(filter_var($email, FILTER_VALIDATE_EMAIL)){
    }else{
        die("Improper email address detected. Please hit your browser back button and try again."); 
        return 1;
    }
}
