Weird upload problem

Hello guys Well, I've been trying to upload a file without much success so far. So I'm trying to find the error but honestly this has become a real puzzle for me. I’ve got the following form: <form enctype=\"multipart/form-data\" name=\"book_add\" method=\"post\" action=".$PHP_SELF."?management=8> <table> <tr><td class=\"nolink\">File to upload:</td> <input type=\"hidden\" name=\"MAX_FILE_SIZE\" value=\"2000\"> <td><input type=\"file\" name=\"formfile\"></td> </tr> </table> The action thing just passes the results to a function for it to process the upload, like this: if ($management) { switch($management) { //Several cases case 8: do_upload_file($_POST, $_FILES) break; } } You may guess what the "do_upload_file" function is for, but all I'm doing at the moment with it is trying to find out what the hell is going on here, so there it is: function do_upload_file($_POST, $_FILES) { if (is_array($_FILES)) echo "$_FILES is ok<br>"; else exit; if (is_array($_POST)) echo "$_POST is ok<br>"; else exit; echo "File tmp_name: ".$_FILES['formfile']['tmp_name']."<br>"; echo "File size: ".$_FILES['formfile']['size']."<br>"; echo "File type: ".$_FILES['formfile']['type']."<br>"; echo "Error: ".$_FILES['formfile']['error']; } The results when trying to upload any kind of file but text/plain ones: $_FILES is ok $_POST is ok File tmp_name: none File size: 0 File type: application/pdf Error: As you can see the file type is being detected (I already tried with the most common types: rtf, doc, xls, zip, ppt, pdf) but I'm getting nothing for name or size. I'm also not getting any error message. If I run the script with a text/plain file it goes through it without a problem. I can't see an error in the way I am handling this upload thing, I also tried not passing the values to a function but doing it directly in the case statement with the same results. Does anyone have a good idea of what's going on here? Hope someone does for I just run out of ideas. Thanks a lot ******************************************************* Wilmar Pérez Network Administrator Library System Tel: ++57(4)2105962 University of Antioquia Medellín - Colombia 2002 *******************************************************
