我在尝试让我的脚本使用从表单收集的信息发送文件附件时遇到了一些麻烦。我使用了PHP Mailer Form with File Attachment并进行了修改以符合我的规范。到目前为止，它将发送没有附加图像的表单信息，但是当我上传图像时，它只会发送附件而不会从表单中发送其他信息。我需要它能够发送带有或没有附件的表单信息。我是php的初学者，所以我不确定为什么这样做。
这是我的代码
<?php
if(isset($_POST['submit'])){
$sendTo = '<myemail@somesite.com';
$subject = 'Request';
$from = $_POST['email_address'];
// Allowed file types. add file extensions WITHOUT the dot.
$allowtypes=array("jpg", "png", "gif");
// Require a file to be attached: false = Do not allow attachments true = allow only 1 file to be attached
$requirefile="true";
// Maximum file size for attachments in KB NOT Bytes for simplicity. MAKE SURE your php.ini can handel it,
// post_max_size, upload_max_filesize, file_uploads, max_execution_time!
// 2048kb = 2MB, 1024kb = 1MB, 512kb = 1/2MB etc..
$max_file_size="5120";
$errors = array(); //Initialize error array
//Check if the file type uploaded is a valid file type.
if((!empty($_FILES["attachment"])) && ($_FILES['attachment']['error'] == 0)) {
// basename -- Returns filename component of path
$filename = basename($_FILES['attachment']['name']);
$ext = substr($filename, strrpos($filename, '.') + 1);
$filesize=$_FILES['attachment']['size'];
$max_bytes=$max_file_size*5120;
//Check if the file type uploaded is a valid file type.
if (!in_array($ext, $allowtypes)) {
$errors[]="Invalid extension for your file: <strong>".$filename."</strong>";
// check the size of each file
} elseif($filesize > $max_bytes) {
$errors[]= "Your file: <strong>".$filename."</strong> is to big. Max file size is ".$max_file_size."kb.";
}
} // if !empty FILES
// send an email
// Obtain file upload vars
$fileatt = $_FILES['attachment']['tmp_name'];
$fileatt_type = $_FILES['attachment']['type'];
$fileatt_name = $_FILES['attachment']['name'];
// Headers
$headers = 'From: '.$from = $_POST['email_address'];
// create a boundary string. It must be unique
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
// Add the headers for a file attachment
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
// Add a multipart boundary above the plain message
$message ="This is a multi-part message in MIME format.\n\n";
$message.="--{$mime_boundary}\n";
$message.="Content-Type: text/plain; charset=\"iso-8859-1\"\n";
$message.="Content-Transfer-Encoding: 7bit\n\n";
$message .= "Name: \t\t".$_POST['name']."\n";
$message .= "Email: \t\t".$_POST['email_address']."\n";
if($_POST['phone_number'] != ""){
$message .= "Phone: \t\t".$_POST['phone']."\n";
$message .= "Date: \t\t".$_POST['full_date']."\n";
}
$message .= "\n";
if($_POST['additional_info'] != ""){
$message .= "Additional Information: \n".$_POST['additional_info']."\n";
}
if (is_uploaded_file($fileatt)) {
// Read the file to be attached ('rb' = read binary)
$file = fopen($fileatt,'rb');
$data = fread($file,filesize($fileatt));
fclose($file);
// Base64 encode the file data
$data = chunk_split(base64_encode($data));
// Add file attachment to the message
$message .= "--{$mime_boundary}\n" .
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
//"Content-Disposition: attachment;\n" .
//" filename=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" .
"--{$mime_boundary}--\n";
}
// Send the completed message
mail($sendTo, $subject, $message, $headers);
header("Location: complete.php");
}
?>

以下是我发送带附件的邮件的方法。一些代码是我的，其中一些代码来自http://php.net/manual/en/function.mail.php。此代码已经过试用和测试，因此应该可以使用。另请参阅sendmail是否已安装。如果在linux上ubuntu系统尝试sudo apt-get install sendmail来安装它。
文件名：index.php
<?php
if( $_POST || $_FILES )
{
// email fields: to, from, subject, and so on
// Here
$from = "someone@somewhere.com";
$to = "someone_else@somewhere_else.com";
$subject = "Mail with Attachment";
$message = "This is the message body and to it I will append the attachments.";
$headers = "From: $from";
// boundary
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
// headers for attachment
$headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\"";
// multipart boundary
$message = "--{$mime_boundary}\n" . "Content-Type: text/plain; charset=\"iso-8859-1\"\n"."Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n";
fixFilesArray($_FILES['attachment']);
foreach ($_FILES['attachment'] as $position => $file)
{
// should output array with indices name, type, tmp_name, error, size
$message .= "--{$mime_boundary}\n";
$fp = @fopen($file['tmp_name'],"rb");
$data = @fread($fp,filesize($file['tmp_name']));
@fclose($fp);
$data = chunk_split(base64_encode($data));
$message .= "Content-Type: application/octet-stream; name=\"".$file['name']."\"\n"."Content-Description: ".$file['name']."\n" ."Content-Disposition: attachment;\n" . " filename=\"".$file['name']."\";size=".$file['size'].";\n"."Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
}
$message .= "--{$mime_boundary}--";
$returnpath = "-f" . $from;
$ok = @mail($to, $subject, $message, $headers, $returnpath);
if($ok){ return 1; } else { return 0; }
}
//This function will correct file array from $_FILES[[file][position]] to $_FILES[[position][file]] .. Very important
function fixFilesArray(&$files)
{
$names = array( 'name' => 1, 'type' => 1, 'tmp_name' => 1, 'error' => 1, 'size' => 1);
foreach ($files as $key => $part) {
// only deal with valid keys and multiple files
$key = (string) $key;
if (isset($names[$key]) && is_array($part)) {
foreach ($part as $position => $value) {
$files[$position][$key] = $value;
}
// remove old key reference
unset($files[$key]);
}
}
}
?>
<html>
<body>
<form method="POST" action="index.php" enctype="multipart/form-data">
<input type="file" name="attachment[]"><br/>
<input type="submit">
</form>
</body>
</html>
顺便说一下，我想为使用sendmail道歉，因为它有点慢。我会尝试发布一个更好的解决方案。
