hi, I have form where administrator has toupload csv file to update dome data in mysql. I was trying to validate entered file but got some crazy stuff I don't understand: for the same uploaded csv file, in different browser I'll get different results: Windows machine and IE: $_FILES['UploadedFile']['type'] = 'text/plain' Windows machine and Firefox: $_FILES['UploadedFile']['type'] = 'application/octet-stream' Windows machine and Opera: $_FILES['UploadedFile']['type'] = 'comma-separated-values' Windows machine and Chrome: $_FILES['UploadedFile']['type'] = '' (doesn't show anything! empty?!?!!??) openSuse machine and Firefox: $_FILES['UploadedFile']['type'] = 'text/csv' openSuse machine and Opera: $_FILES['UploadedFile']['type'] = 'text/comma-separated-values' openSuse machine and Konqueror: $_FILES['UploadedFile']['type'] = 'text/csv' ok. what's CORRECT way to validate uploaded file? thanks. -afan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
