Question

所以我有这个表格。

这是一个非常简单的邮件/通讯表格。

  <form action="http://localhost/website/subscribe.php" method="POST" id="signup_form">
  <label for="email"><p id = "subText">Subscribe</p></label>
  <input type="text" name="email" size="30" class="required email txtEmail" placeholder = "Enter Email Address">
  <input type="submit" value="Go" name="submit" class = "goButton"/>
  </form>

我有这个subscribe.php文件。

<?php
if(isset($_POST['email']))
{
    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "email@email.com";
    $email_subject = "Subscription";

    function died($error)
    {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }

    // validation expected data exists
    if( !isset($_POST['email']))
    {
        died('We are sorry, but there appears to be a problem with the form you submitted.');       
    }

    $email_from = $_POST['email']; // required
    $error_message = "";
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';

    if(!preg_match($email_exp,$email_from))
    {
        $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
    }

    if(strlen($error_message) > 0)
    {
        died($error_message);
    }

    $email_message = "Form details below.\n\n";

    function clean_string($string)
    {
        $bad = array("content-type","bcc:","to:","cc:","href");
        return str_replace($bad,"",$string);
    }

    $email_message .= "Email: ".clean_string($email_from)."\n";

    // create email headers
    $headers = 'From: '.$email_from."\r\n".
               'Reply-To: '.$email_from."\r\n" .
               'X-Mailer: PHP/' . phpversion();
    @mail($email_to, $email_subject, $email_message, $headers);  
?>
<!-- include your own success html here -->
Thank you for contacting us. We will be in touch with you very soon.
<?php
}
?>

我发现here，我只是编辑了一下以适合我的表格。我是PHP的新手，我还处于练习阶段。

我得到的错误是

PHP Parse error:  syntax error, unexpected T_VARIABLE in /home/techstars05/www/website/subscribe.php on line 6, referer: http://localhost/website/index.html

我使用sublime text 2来编辑代码，我注意到＆＃34; if（isset（$ _ POST [＆＃39; email＆＃39;]））＆＃34;＆＃39; s＆＃39;如果＆＃39;与subscribe.php文件中的其他ifs颜色不同。它的粉红色，而其他的是紫罗兰色。我不太确定这是什么意思，我试着跟踪代码，但对我的新手来说它看起来很好。

TIA

尝试一下：

<?php

if(isset($_POST['email'])) {
    //email is set
    $email_from = $_POST['email'];
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
    if(preg_match($email_exp,$email_from)) {
        //email data
        $email_from = $_POST['email'];
        $email_to = "email@email.com";
        $email_subject = "Subscription"; 
        //create body
        $email_message = "Form details below.\n\n";
        $email_message .= "Email: ".clean_string($email_from)."\n";
        // create email headers
        $headers = 'From: '.$email_from."\r\n".
        $headers .= 'Reply-To: '.$email_from."\r\n" .
        $headers .= 'X-Mailer: PHP/' . phpversion();     
        if(mail($email_to, $email_subject, $email_message, $headers)){
            echo "email sent successfully";
            exit();
        }else{
            echo "email failed to send";
        }   
    }else{
        echo "email is not valid";
    }
}else{
   echo "email is not set";
}


function clean_string($string){
  $bad = array("content-type","bcc:","to:","cc:","href");
  return str_replace($bad,"",$string);
}
?>
