问题
I'm having some trouble trying to get my script to send a file attachment with the information collected from the form. I used PHP Mailer Form with File Attachment and modified to fit my specification. So far it will send the form information without the attached image but when I upload an image it will only send the attachment and no other information from the form. I need it to be able to send the form information with or without an attachment. I'm a beginner with php so I'm not sure why its doing this.
Here is my code
<?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");
}
?>

Here is what I have done to send a mail with an attachment. Some of the code is mine and some of it has been taken from http://php.net/manual/en/function.mail.php. This code has been tried and tested so, it should work. Also see if sendmail is installed. If on linux ubuntu system try sudo apt-get install sendmail to install it.
File Name: 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>
By the way I would like to apologize for using sendmail since it is a bit slow. I will try to post a better solution.
