I just updated to 4.013 and PHP5 HTTP_POST does not work. Verified working fine in 4.012 and Apache. Here's the code: Code: <form method=post action="pictureform.php"> <input type="FILE" name="userpic" size="30"> <input type=submit> </form> PHP: $source = $HTTP_POST_FILES['userpic']['tmp_name']; Under 4.012 and Apache $source will return the temporary file location of the file (e.g. /tmp/adoije) 4.013 returns a null value. It appears the temporary file is not actually created from the upload form. edit: Changing the script to the $_FILES super global solved the issue. Although this might be a problem for older scripts.
