Unable to set upload_tmp_value

Hi, I'm writing this email because I'm unable to find a solution for my problem. I'm creating an email with enable user to send attachment in the email but the file is not attached to the email successfully. $fileatt = $_FILES['fileUpload']['tmp_name']; $fileatt_type = $_FILES['fileUpload']['type']; $fileatt_name = $_FILES['ffileUpload']['name']; $headers = "From: $from"; if (is_uploaded_file($fileatt)) { // Read the file to be attached ('rb' = read binary) $file = fopen($fileatt,'rb'); $data = fread($file,filesize($fileatt)); fclose($file); // Generate a boundary string $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}\""; // 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"; } mail($to, $subject, $message, $headers); What I discover is the program unable to retrieve information of the uploaded file. The following values are null: - $fileatt - $fileatt_type - $fileatt_name In my php.ini, I have configured the path for upload_tmp_dir ; Whether to allow HTTP file uploads. file_uploads = On ; Temporary directory for HTTP uploaded files (will use system default if not ; specified). upload_tmp_dir = "C:\TEMP" ; Maximum allowed size for uploaded files. upload_max_filesize = 2M but when I view the php info in html, the upload_tmp_dir = no value My questions are: 1. To create an email with attachment, setting value for upload_tmp_dir is it a compulsory? Is there any additional parameters that need to be set in php.ini? 2. After setting the value for upload_tmp_dir in php.ini, why it is not reflected in info.html? 3. Do we need to provide the full file path for upload_tmp_dir? I'm using IIS v5.1, php 5.2.9, OS Win XP. Hope you can help me resolve my problem. Thanks in advance. Regards, Brian Teh The information contained in this email inclusive of all attachments may be confidential and /or legally privileged.
