电子邮件发布数据和 Base 64 编码冗余

尝试使用此函数，请注意我手动获取$mime类型，这是因为 getmimetype 函数在其他 PHP 版本上不起作用。

public static $mime_type = array(
                "doc"       =>    "application/msword",
                "docx"      =>    "application/vnd.openxmlformats-officedocument.wordprocessingml.document",
                "pdf"       =>    "application/pdf",
                "xlsx"      =>    "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
                "gif"       =>    'image/gif',
                "jpg"       =>    'image/jpeg',
                "png"       =>    'image/png',
                "txt"       =>    'text/plain',
                "rtf"       =>    'application/rtf'
);
/*
 * @des    - return mime type base on file extension
 * @notes  - I use this because some of the php function that get the mimetype
 *           is not working on other php version
 * @params string $filename  - full filename of the file e.g. (imat.png)      
 * @return - mime type of the file
 * @requiremetns array $mime_type - an array of file extension with equivalent mime type        
 */
private static function getMimeType($filename)
{
    $filename = basename($filename);
    $ext = explode(".", $filename);
    $ext = $ext[count($ext) - 1];
    return self::$mime_type[$ext];
}

/*
 * @params string $from - this will be the sender of an email
 * @params string $subject - subject of the email
 * @params array $attachments - an array of attachment e.g. array([0] => array("path" => "public_html/imat.com/data/imat.jpg", "filename" => "imat.jpg"))
 * #the attachments["path"] must be an ABSOLUTE PATH
 * @params string $email_message - email message message of the email(can be an html format)
 * @params string $to - this will be the receiver of an email
 * @params string $cc - this will be the carbon copy of the email 
 * @return boolean - return true/false
 */
public static function mail_with_attachment($from, $subject, $attachments, $email_message, $to , $cc = NULL)
{
    $random_hash = sha1(md5(date('r', time()))); 
    //define the headers we want passed. Note that they are separated with 'r'n 
    $headers = array();
    $headers[] = "MIME-Version: 1.0";
    $headers[] = "From: $from";
    $headers[] = "Content-Type: multipart/mixed; boundary='"PHP-mixed-".$random_hash."'""; 
    $headers[] = "X-Mailer: PHP/".phpversion();
    $headers   = implode("'r'n", $headers);
    //define the message
    $message = array();
    $message[] = "--PHP-mixed-$random_hash";        
    $message[] = "Content-Type: multipart/alternative; boundary='"PHP-alt-{$random_hash}'"";
    $message[] = "--PHP-alt-{$random_hash}";
    $message[] = "Content-Type: text/html; charset='"iso-8859-1'"";
    $message[] = "Content-Transfer-Encoding: 7bit";
    $message[] = "'r'n".$email_message."'r'n'r'n";
    foreach($attachments as $attachment)
    {
        $mime_type = self::getMimeType($attachment['filename']);
        $chunk_attachment = chunk_split(base64_encode(file_get_contents($attachment['path'])));
        $message[] = " 'r'n--PHP-mixed-$random_hash";
        $message[] = "Content-Type: $mime_type; name='"{$attachment['filename']}'"";
        $message[] = "Content-Transfer-Encoding: base64";
        $message[] = "Content-Disposition: attachment";
        $message[] = "'r'n".$chunk_attachment."'r'n";
    }
    $message[] = "--PHP-mixed-$random_hash";
    $message   = implode("'r'n", $message);
    //send the email 
    return @mail( $to, $subject, $message, $headers ); 
}

我让它与PHPMailer一起工作。

require '/blahblah/ios/PHPMailer/PHPMailerAutoload.php';
$email = new PHPMailer();
$email->From      = 'limitedwave@gmail.com';
$email->FromName  = 'Store Agent';
$email->Subject   = $_POST['caption'];
$email->Body      = 'the image';
$email->AddAddress( 'limitedwave@gmail.com' );
$file_to_attach = '/blahblah/ios/photos/'.$name.'jpg';
$email->AddAttachment( $file_to_attach , '2014-03-31221.jpg' );
return $email->Send();

但是 - 当与我的其他代码集成时，它似乎不起作用。我怀疑这是因为电子邮件内容在进程有机会解码并将图像保存在服务器上之前运行。

有谁知道我可能会如何延迟运行电子邮件 - 我想我当然会把它放在一个函数中，但是我怎么能等到保存图像后再调用该函数？

完整代码（不附加图像）：

<?php
$con = mysql_connect("blahblah","tpwebdata","blahblah");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
 // get base64 encoded image from iOS pass vai POST 
$base = $_POST['image'];
// set final URL ($path) for image
$date = date("Y-m-d");
$name  = "" . $date.rand(0, 999).".jpg";
$path  = "http://trendypieces.net/ios/photos/" . $name;
 // save image to location this file resides
if (file_exists($name)) {
    echo "File already exists";
} else {
    $binary = base64_decode($base);
    $file = fopen($name, 'wb');
    fwrite($file, $binary);
    fclose($file);
    echo "Image uploaded";
}
// perform database insert for web site use
mysql_select_db("tpwebdata", $con);
$sql="INSERT INTO latest (caption, image)
VALUES
('$_POST[caption]','$path')"; 
echo "OK";
if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
// mail it --------------------
require '/blahblah/ios/PHPMailer/PHPMailerAutoload.php';
$email = new PHPMailer();
$email->From      = 'limitedwave@gmail.com';
$email->FromName  = 'Store Agent';
$email->Subject   = $_POST['caption'];
$email->Body      = 'Trendy images.';
$email->AddAddress( 'limitedwave@gmail.com' );
$file_to_attach = '/blahblah/ios/photos/'.$name.'jpg';

$email->AddAttachment( $file_to_attach , '2014-03-31221.jpg' );
return $email->Send();

mysql_close($con);
