Recently, I was dealing with a rather dumb issue between various browsers and how they display\/download PDF files. What was dumb was that one browser would display an error when the file originates from a CDN, while when locally available on the same server, no issues. Let’s not forget, visa versa for the other browser.
\n
\nFirst thing I managed to do was reach out to the browser and CDN in question on twitter, hoping this was a known issue. With my luck, no go. So, let’s just force a file download and avoid the headache all in all. We’ll call this getfile.php.<\/p>\n
You first need to create a page that will be referenced, which will initiate the file download. In this example, we pass in the name of the file without the extension.<\/p>\n
http:\/\/domain.com\/downloads\/getfile.php?file=(name_of_file)<\/p>\n
\r\n<?php\r\n header("Content-Type: application\/octet-stream");\r\n\r\n $file = "http:\/\/domain.com\/downloads\/".$_GET["file"].".pdf";\r\n $name = $_GET["file"].".pdf";\r\n header("Content-Disposition: attachment; filename=".urlencode($name));\r\n header("Content-Type: application\/force-download");\r\n header("Content-Type: application\/octet-stream");\r\n header("Content-Type: application\/download");\r\n header("Content-Description: File Transfer"); \r\n header("Content-Length: ".filesize($file));\r\n\r\n flush();\r\n\r\n $fp = fopen($file, "r");\r\n while (!feof($fp)) {\r\n echo fread($fp, 65536);\r\n flush();\r\n }\r\n\r\n fclose($fp);\r\n?>\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"Recently, I was dealing with a rather dumb issue between various browsers and how they display\/download PDF files.
