PHP PDO发送电子邮件代码仅在纯文本时发送-需要发送HTML

Question

我正在执行以下代码：（1）将记录从一个表移动到另一个表（在同一数据库中），（2）将表1的内容发送到预定的电子邮件，以及（3）删除表1的内容。表1-模拟“添加到购物车”功能。

我的问题是，如果未在mail（）上发送$ headers，则下面的代码将仅能成功发送电子邮件。 但是，我需要将表内容发送为HTML或至少允许

用于不同的记录。 如果有可能未发送电子邮件，则也不执行代码的删除部分。 我究竟做错了什么？

提前致谢！

修改后的代码（如果我不发送$headers ）

 <?php include '../config/database.php'; date_default_timezone_set('CET'); $date = date('Ymd H:i:s'); $query = "INSERT INTO claims_archive (t20pctID, total_amount, user_id, sent) SELECT t20pctID, total_amount, user_id, @date FROM cart WHERE t20pctID LIKE '%sony%'"; $stmt = $con->prepare($query); if ($stmt->execute()) { $query = "SELECT t.t20pctID, t.main_artist, t.track_title, t.original_album, c.total_amount FROM cart c LEFT JOIN tblclaims t ON t.t20pctID = c.t20pctID WHERE t.t20pctID LIKE '%sony%' ORDER BY t.main_artist"; $stmt=$con->prepare($query); $stmt->execute(); $to = "testmail2@gmail.com"; $subject = "Test"; $headers = "MIME-Version: 1.0" . "\\r\\n"; $headers .= "Content-type:text/html;charset=UTF-8" . "\\r\\n"; $headers .= "From: Test <testmail1@mail.com>" . "\\r\\n"; $body = "Sent on: ". $date . "-\\r\\n"; while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) { extract($row); $body .= "Track title: ".$row ["track_title"]. "-"; } $success = mail($headers, $to, $subject, $body); if ($success) { $query_delete = "DELETE FROM cart WHERE t20pctID LIKE '%sony%'"; $stmt = $con->prepare($query_delete); $stmt->execute(); header('Location: cart.php?action=sent'); } else { header('Location: cart.php?action=sent_failed'); } } else { header('Location: cart.php?action=sent_failed'); } include 'layout_foot.php'; ?>

Answer 1

在任何情况下都不会执行您的删除代码，因为在此代码运行之前您正在重定向。

1. 删除header('Location: cart.php?action=sent'); 在下面写到if ($stmt->execute()) { 。

2. 将您的删除代码置于标头之前的if($success)条件中。

3. 使用以下代码更新$ headers变量，并将其包含在您的mail函数中：

    $headers = "MIME-Version: 1.0" . "\\r\\n"; $headers .= "Content-type:text/html;charset=UTF-8" . "\\r\\n"; $headers .= 'From: Test <testmail1@mail.com>' . "\\r\\n"; 

Answer 2

这个

$success = mail($headers, $to, $subject, $body);

没有正确的参数顺序...

请参阅http://php.net/manual/de/function.mail.php正确的签名是这样的：

bool mail ( string $to , string $subject , string $message 
         [, string $additional_headers [, string $additional_parameters ]] )

所以

$success = mail($to, $subject, $body, $headers);
