Upload file in email form

Recommended Posts

I have an email form where the visitor can upload a file as an attachment that then gets emailed. If they choose not to upload a file the email still comes through with an attachment (txt file).
How can I get rid of the attachment if there is no uploaded file?

Here's the code I have for the attachment:[code]  // if the upload succeded, the file will exist
  if (file_exists($tmp_name)){

      // check to make sure that it is an uploaded file and not a system file
      if(is_uploaded_file($tmp_name)){

        // open the file for a binary read
        $file = fopen($tmp_name,'rb');

        // read the file content into a variable
        $data = fread($file,filesize($tmp_name));

        // close the file
        fclose($file);

        // now we encode it and split it into acceptable length lines
        $data = chunk_split(base64_encode($data));
    }
}[/code]
