用 php 发送 HTML 电子邮件？

Question

我有一个脚本，可以在成功购买后使用 paypal IPN 发送电子邮件。如何修改脚本以发送 HTML 电子邮件？

<?php

// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';

foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}

// post back to PayPal system to validate

$header = "POST /cgi-bin/webscr HTTP/1.1\r\n";

// If testing on Sandbox use: 
// $header .= "Host: www.sandbox.paypal.com:443\r\n";
$header .= "Host: ipnpb.paypal.com:443\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

// If testing on Sandbox use:
//$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
$fp = fsockopen ('ssl://ipnpb.paypal.com', 443, $errno, $errstr, 30);

// assign posted variables to local variables
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];

//set email variables
$From_email = "From: admin@domain.com";
$Subject_line = "Thanks";

$email_msg = "Thanks for purchasing my item. Your order will be delivered in 3-4 days. We       appreciate your business.";
$email_msg .= "\n\nThe details of your order are as follows:";
$email_msg .= "\n\n" . "Transaction ID: " .  $txn_id ;
$email_msg .= "\n" . "Payment Date: " . $payment_date;

if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
// check the payment_status is Completed
// check that txn_id has not been previously processed
// check that receiver_email is your Primary PayPal email
// check that payment_amount/payment_currency are correct
// process payment

$mail_From = $From_email;
$mail_To = $payer_email;
$mail_Subject = $Subject_line;
$mail_Body = $email_msg;

mail($mail_To, $mail_Subject, $mail_Body, $mail_From);


}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation

$mail_From = $From_email;
$mail_To = $receiver_email;
$mail_Subject = "INVALID IPN POST";
$mail_Body = "INVALID IPN POST. The raw POST string is below.\n\n" . $req;

mail($mail_To, $mail_Subject, $mail_Body, $mail_From);

}
}
fclose ($fp);
}
?>

Answer 1

您需要发送带有内容类型的完整标题，而不仅仅是 mail_from。这是一个例子

$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
$headers .= $mail_From . "\r\n";
mail($mail_To,$mail_Subject,$mail_Body,$headers);

http://www.w3schools.com/php/func_mail_mail.asp

在您的代码中：

$mail_From = $From_email; $mail_To = $payer_email; $mail_Subject = $Subject_line; $mail_Body = $email_msg;

邮件($mail_To, $mail_Subject, $mail_Body, $mail_From);

$mail_From 是第四个参数（标题）。创建一个新字符串，其中包含 html 电子邮件的完整标题以及：$_From

$mail_From = $From_email;
$mail_To = $payer_email;
$mail_Subject = $Subject_line;
$mail_Body = $email_msg;
//start $headers
$headers = "MIME-Version: 1.0" . "\r\n"; 
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n"; //adds content type to headers
$headers .= $mail_From . "\r\n"; //adds the sender details
mail($mail_To,$mail_Subject,$mail_Body,$headers); //sends the email

如果你 echo $headers 会是这样的

MIME-Version:1.0
Content-type:text/html;charset=iso-8859-1
From:email@email.com

Answer 2

只需将 HTML 放入邮件正文中，大多数邮件客户端应该都能识别出来。

更正确的答案还包括邮件中适当的 Content-Type 标头 (text/html)。

一个完整的答案就是我所做的：

<?php
$html = <<<HTML
<!DOCTYPE HTML>
<html>
    <head>
        <meta http-equiv="Content-Type" value="text/html; charset=iso-8859-1" />
        <title>Title here</title>
    </head>
    <body>
        <p>My mail content here.</p>
        <hr />
        <p style="font-size: 8pt; font-style: italic;">Some signature here</p>
    </body>
</html>
HTML;
$text = preg_replace("(\n{2,})","\n",strip_tags(str_replace(Array("\t","<hr />"),Array("","===================="),$html)));
$seperator = uniqid();
mail("user@example.com","Title here",
        "--".$seperator."\r\n"
        ."Content-Type: text/plain\r\n\r\n"
        .$text."\r\n"
        ."--".$seperator."\r\n"
        ."Content-Type: text/html\r\n\r\n"
        .$html."\r\n"
        ."--".$seperator."--",
    "From: My name <me@example.com>\r\n"
    ."MIME-Version: 1.0\r\n"
    ."Content-Type: multipart/alternative; boundary=".$seperator);
?>

这不仅会发送所有正确的标头以免客户端猜测，它还会为不想要 HTML 电子邮件的用户自动生成纯文本版本。

Answer 3

通过 PHP 发送 HTML 电子邮件使用与文本电子邮件完全相同的 ma​​il 功能：

mail($to, $subject, $message, $headers);

$to = 'bob@example.com';

$subject = 'Website Change Reqest';

$headers = "From: " . strip_tags($_POST['req-email']) . "\r\n";
$headers .= "Reply-To: ". strip_tags($_POST['req-email']) . "\r\n";
$headers .= "CC: susan@example.com\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";

$message = '<html><body>';
$message .= '<h1>Hello, World!</h1>';
$message .= '</body></html>';
