Question

问题在于这个PHP代码通过AJAX函数并将Form的内容发送到特定的电子邮件。

脚本的基本部分正常工作，但是当电子邮件到达时，某些文本似乎会在收件箱中转换。具体来说，单引号（'）替换为双引号（“）。

搜索网页并浏览SO后，我找不到答案。任何帮助将深表感谢。代码如下。

<?php
require '../config/squareconfig.php';

   if($_POST)
{
//check if ajax request, exit if not
if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {
    die();
} 

//check $_POST vars are set, exit if any missingc
if(!isset($_POST["usercName"]) || !isset($_POST["usercEmail"]) || !isset($_POST["usercMessage"]))
{
    die();
}

//Sanitize input data using PHP filter_var().
$user_cName        = filter_var($_POST["usercName"], FILTER_SANITIZE_STRING);
$user_cEmail       = filter_var($_POST["usercEmail"], FILTER_SANITIZE_EMAIL);
$user_cMessage     = filter_var($_POST["usercMessage"], FILTER_SANITIZE_STRING);
if(strlen($user_cName)<4) // If length is less than 4 it will throw an HTTP error.
{
    header('HTTP/1.1 500 Name is too short or empty!');
    exit();
}
if(!filter_var($user_cEmail, FILTER_VALIDATE_EMAIL)) //email validation
{
    header('HTTP/1.1 500 Please enter a valid email!');
    exit();
}
if(strlen($user_cMessage)<5) //check emtpy message
{
    header('HTTP/1.1 500 Too short message! Please enter something.');
    exit();
}

//proceed with PHP email.
$headers = 'From: '.$user_cEmail.' ';
$templatemail = PHP_EOL . PHP_EOL . 'User E-mail:' . PHP_EOL . $user_cEmail;
@$sentMail = mail($squarecmail, $squarecsubject, $user_cMessage . PHP_EOL . $templatemail, $user_cName);

if(!$sentMail)
{
    header('HTTP/1.1 500 Could not send mail! Sorry..');
    exit();
}else{
    echo $squarectymessage . '<br>' . '<div class="subagain">' . $squarecontagain . '</div>';
    ?>
    <script type="text/javascript">
        $('#contact_form').fadeOut();
    </script>
    <?php

}
}

我不确定“问题”，但合理的建议可能是将电子邮件发送为HTML，因为filter_var()会返回非字母数字字符的html实体。指定电子邮件的内容类型。

$headers = "From: yomama@jokes.com\r\n";
$headers .= "Reply-To: arenot@always.funny\r\n";
$headers .= "CC: yomamasobig@whenshewearsayellowcoatppleyell.taxi\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";

$mail_sent = @mail($sender, $subject, $message, $headers);

上述建议是基于以下事实：FILTER_SANITIZE_STRING会在提到的字符上导致html-unicode编码（或某些此类编码）。

$ php-shell

>> echo filter_var('\' -- "', FILTER_SANITIZE_STRING);
