Trapping for PDF Type and file size in a UPLOAD form...

I am trying to create an UPLOAD form and need to figure a way to only allow PDF files to be selected. Something like: <html> <body> <form enctype="multipart/form-data" action="upload.php" method="post"> <input type="hidden" name="MAX_FILE_SIZE" value="1000000" accept="application/pdf" /> Choose a file to upload: <input name="uploaded_file" type="file" /> <input type="submit" value="Upload" /> </form> </body> </html> It is documented online that I can pass a parameter ACCEPT="applaction/pdf", BUT it is not recognized in most browsers. It was suggested by someone that I could trap for this using a JAVASCRIPT. Can someone assist with a snippet of javascript code to trap for this for me? This is the end result I need: If the user selects a file that IS NOT a PDF file, display an javascript alert "You can only upload PDF files. Please try again." If the user selects a PDF file greater than 1MB, display an javascript alert "File uploads may not exceed 1M in file size. Please try again." I appreciate any help that can be offered. Thanks in advanced! Don Wieland
