hacker Posted October 5, 2011 Share Posted October 5, 2011 Larry, If an attempt is made to upload a file with a file size > post_max_size, add_pdf.php produces "undefined index" error messages with respect to the 'pdf' index referenced by $_FILES; and, the variable state messages indicate $_FILES is empty. Under these conditions, how does the switch contained under elseif(!isset($_SESSION['pdf'])) manage to work since $_FILES is empty? Will a default switch condition always work if the variable being tested is NULL? I'm also curious why you changed the line of code in your book just above switch($_FILES['pdf']['error']) from simply else to elseif(!isset($_SESSION['pdf'])) before you made the script available for download.
