Upload file - $HTTP_POST_FILES empty (thinking in harakiri)

Hi guys!.. i'm really grief-stricken. I had spend all the morning looking for solution to my problem, PLEASE.. Could somebody help me? ' -(. I tried the example from http://www.php.net/manual/en/features.file-upload.php but i get the message "Possible file upload attack", I notice that this message is because $HTTP_POST_FILES was absolutely empty.. BUT i don't know WHY is empty!!!!!!! - My form.php file are: <form enctype="multipart/form-data" action="upload.php" method="post"> <input type="hidden" name="MAX_FILE_SIZE" value="2000000"> Send this file: <input name="userfile" type="file"> <input type="submit" value="Send File"> </form> - My upload.php file are: <?php // In PHP earlier then 4.1.0, $HTTP_POST_FILES should be used instead of $_FILES. if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {

    copy($_FILES['userfile']['tmp_name'], "/home/juque/public_html/VI_eaf/upload/");

} else {

    echo "Possible file upload attack. Filename: " . $_FILES['userfile']['name'];

} /* ...or... */ move_uploaded_file($_FILES['userfile']['tmp_name'], "/home/juque/public_html/VI_eaf/upload/"); ?> - My php.ini file_uploads = On - My upload directory had 777 permission. - My upload file is a simple .txt of 32 Bytes. - PHP 4.1.2 / Apache 1.3.23 - I have changed HTTP_POST_FILES for $_FILES Please GUYS.. any idea will be really appreciate. --jp
