来自表单的 WP 邮件附件，没有在文件管理器上上传文件答案

【问题标题】：WP mail attachment from form without upload file on filemanager来自表单的 WP 邮件附件，没有在文件管理器上上传文件
【发布时间】：2016-05-22 11:51:50
【问题描述】：

从一个表单，通过 wp_mail 函数，我试图发送一封带有附件的电子邮件，而不是将文件上传到文件管理器。我收到带有附件的电子邮件。但附件名称不正确且没有文件类型。请帮忙解决这个问题。

这是 HTML 表单

<form action="POST" enctype="multipart/form-data">
    <table>
        <input type="file" name="Attached">
        <input type="Submit" name="Submit">
    </table>
</form>

这是我的 PHP 代码

if (isset($_POST['Submit'])) {
    $attachments = $_FILES['Attached']['tmp_name'];

    $recipients = "john@mail.com";
    $SenderName = get_bloginfo('name');
    $SenderEmail = "noreply@domain.com";
    $body   = "How are you what are you doing now. bla bla bla";

    $recipients = array($to);
    $headers[] = "From: $SenderName <$SenderEmail>" . "\r\n";
    $headers[] = "Content-Type: text/html";
    $subj = "This is mail subject";
    $SendMail   = wp_mail( $recipients, $subj, $body, $headers, $attachments );
}

图片转base64
你能把这个代码发给我吗？
先将上传的数值图片通过js转换为base64，并赋值给隐藏字段值，该数值将包含在POST中，然后您可以按照此发送带有附件的电子邮件，webcheatsheet.com/php/…，有很多这里或谷歌的信息，只需搜索它;）

好吧，我不得不为此想出解决方法

我做的是

上传文件到服务器
带有 wp-mail 的电子邮件
邮件成功与否；取消链接上传的图片

1.上传文件到服务器

    /*image upload */
/* GET File Variables */
$target_dir = $_SERVER['DOCUMENT_ROOT']. "/uploads/";
$image_name = $_FILES['YOUR_IMAGE']['name'];
$target_file = $target_dir . basename($_FILES['YOUR_IMAGE']['name']);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image

$check = getimagesize($_FILES["YOUR_IMAGE"]["tmp_name"]);
if($check !== false) {
    echo "File is an image - " . $check["mime"] . ".";
    $uploadOk = 1;
} else {
    echo "File is not an image.";
    $uploadOk = 0;
}


// Check file size
if ($_FILES["YOUR_IMAGE"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
    && $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
    // if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["YOUR_IMAGE"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["YOUR_IMAGE"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}

$attachment = array($target_file);

2.使用 wp-mail 发送电子邮件

    $to = $Email; // put your email here
        $headers = array('Content-Type: text/html; charset=UTF-8','From:' . $name . '<' . $fromEmail . '>');

        // $headers = 'From:' . $name . '<' . $studentEmail . '>' . "\r\n"; // put user's email here or duplicate your email
        $subject = 'Apply Online Form';

        if (wp_mail($to, $subject, $message, $headers, $attachment ) === false) {
            echo "Error";
             unlink($target_file);
        } else {
             unlink($target_file);
            echo "<h3> Mail Sent Successfully</h3>";
        }

3.发邮件成功或不取消上传图片的链接

unlink($target_file);
