Allow ability to NOT attach file in PHP mail form
spastickyle replied to spastickyle's topic in PHP Coding Help
Yes, that's correct. When i attach a file, it worked great, no problems. But when i choose to not attach a file, I get the error. I want the ability to submit my contact information without having to attach a file if I don't have one. Attach1 is the name of the first attachment input. There is UPLOAD_ERR_NO_FILE because there is no file by choice. -
Allow ability to NOT attach file in PHP mail form

Thanks Mac_gyver. The code in example 3 requires an upload path which I'm trying to avoid. My reasoning may seem frivolous but I want this to be as idiot proof as possible and directory structures and permissions seem like another element for my client to screw up. -
Allow ability to NOT attach file in PHP mail form
spastickyle replied to spastickyle's topic in PHP Coding Help
Thanks for the suggestion. I got the following output which confirms what I suspected. null is in the array and null is not one of the accepted files. Which got me to test a rather dirty fix. I added "" to $allowedExtensions and now it works when I choose not to attach a file. The obvious issue with this is malicious files with no extensions. -
I am trying to create a simple mail form with multiple attachments for our HR department. When I choose not to attach a file, or in the case of allowing multiple attachments, not attaching a second file, I get the following error. I'm assuming that the foreach is looking for the file extension and seeing null in the array (hense the blank when displaying the $ext in the error message when die is called). The HR department wants to have multiple attachments in case an applicant wants to submit a cover letter and resume. But my code so far won't allow an applicant to submit a resume without a cover letter. I'm not a proficient PHP programmer, but I want to expand my knowledge. How can I prevent null values (in this case, no file attachment) from adding to the array? Thanks in advance. Here's the php code: <?php error_reporting(E_ALL); ini_set('display_errors', 1); ini_set("SMTP","123.456.789.123"); ini_set("smtp_port","25"); if(isset($_FILES) && (bool) $_FILES) { $allowedExtensions = array("pdf","doc","docx","gif","jpeg","jpg","png","rtf","txt"); $files = array(); foreach($_FILES as $name=>$file) { $file_name = $file['name']; $temp_name = $file['tmp_name']; $file_type = $file['type']; $path_parts = pathinfo($file_name); $ext = $path_parts['extension']; if(!in_array($ext,$allowedExtensions)) { die("File $file_name has the extensions $ext which is not allowed"); } array_push($files,$file); } // email fields: to, from, subject, and so on $to = "mail@example.com"; $from = "webmaster@example.com"; $subject ="test attachment"; $message = "this is a simple test message"; $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 $message = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/plain; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n"; $message .= "--{$mime_boundary}\n"; // preparing attachments for($x=0;$x<count($files);$x++){ $file = fopen($files[$x]['tmp_name'],"rb"); $data = fread($file,filesize($files[$x]['tmp_name'])); fclose($file); $data = chunk_split(base64_encode($data)); $name = $files[$x]['name']; $message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$name\"\n" . "Content-Disposition: attachment;\n" . " filename=\"$name\"\n" . "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n"; $message .= "--{$mime_boundary}\n"; } // send $ok = mail($to, $subject, $message, $headers); if ($ok) { echo "<p>mail sent to $to!</p>"; } else { echo "<p>mail could not be sent!</p>"; } } ?> <html> <body> <form method="post" action="MultipleEmailAttachments.php" enctype="multipart/form-data"> <input type="file" name="attach1"/> <input type="file" name="attach2"/> <input type="submit" value="submit"/> </form> </body> </html>
