wp_Mail()中已发送邮件，但未收到附件

Question

我是wordpress的新手。我正在尝试发送一封带有附件的邮件。但每次邮件都在发送，但附件却没有。我在这里搜索了几乎所有与此主题相关的帖子，但所有的解决方案都失败了。我检查了很多次路径，从"上传"文件夹中发现它是正确的。请帮帮我。这是我的代码，

<?php
if(isset($_POST['email'])){
$to = $_POST['email'];
$pdf = $_POST['pdf'];
$subject = "Presidency Alumni Annual Report";
$message = "Please download the attachment.";
$headers = 'From: Presidency Alumni Association Calcutta <[e-mail]>' . "n";
if($pdf == 'a'){
$attachments = array(WP_CONTENT_DIR . 'uploads/2015/01/Coffee-Mug-Banner.jpg');
}
else if($pdf == 'b'){
$attachments = array(WP_CONTENT_DIR . 'uploads/2014/08/Alumni-Autumn-Annual-2014.pdf');
 }
else{
$attachments = array(WP_CONTENT_DIR . 'uploads/2014/08/Autumn-Annual-2012.pdf');
}
wp_mail($to, $subject, $message, $headers, $attachments);
print '<script type="text/javascript">';
print 'alert("Your Mail has been sent successfully")';
print '</script>';  
}
?>

发生这种情况的最可能原因是条件if($pdf == 'a') {...} else if ($pdf == 'b') {...})不成立。检查这个变量pdf是否在您的postHTML表单中设置正确。

还要确保常量WP_CONTENT_DIR包含一些内容，即不是空字符串，因为否则你的附件路径将无效，即最好访问你的上传目录，如下所示：

<?php $upload_dir = wp_upload_dir(); ?>

$upload_dir现在包含如下内容（如果成功）：

Array (
    [path] => C:pathtowordpresswp-contentuploads20105
    [url] => http://example.com/wp-content/uploads/2010/05
    [subdir] => /2010/05
    [basedir] => C:pathtowordpresswp-contentuploads
    [baseurl] => http://example.com/wp-content/uploads
    [error] =>
)

然后，修改您的代码：

$attachments = array($upload_dir['url'] . '/2014/08/Autumn-Annual-2012.pdf');
