Hello all, I'm fairly new to PHP (hence, the post in Newbie Help), and I'm stuck on how to accomplish a particular redirect. I'm trying to view a PDF file, based on an entry by a user. The PHP file is on a local intranet, and the file is located on a networked drive. The user enters an Item # and then a PDF file containing the Vendor information for that Item is displayed. The files are in location: \\serv_1\vendors\ven_info\ The files are all named like [Item #]_vend.pdf (ie. 123456_vend.pdf). The code I've written is as follows: $item_num = $_POST['item_num']; if (is_numeric($item_num) && strlen($item_num) == 6) { $default_filepath = "\\serv_1\vendors\ven_info\"; $default_ext = "_vend.pdf"; $filename = $default_filepath . $item_num . $default_ext; if (file_exists($filename)) { header("Location: " . $filename); exit; } else { $msg = "No Vendor Info can be found for Item # " . $item_num; } } else { $msg = "Item Number must be 6-digit number."; } When I try to run the code, the file_exists function works (ie. it can tell if the file exists or not). But when I try to redirect to the PDF file, I get an error saying "Cannot find server". Is there any way I can get the PDF file to open using a header function, or do I need to use something else? Is the problem caused by the location I'm trying to redirect to? Maybe I can't user \\servername\folder format? Any help is appreciated. Thanks, Jay
