If I have a page with url download.php?id=312, which downloads a file from the server, can I somehow find out the absolute path to the file on the server? The filename is 'hidden' since it's downloaded through the file download.php but can the file give a clue where the file was downloaded from or is it completely hidden?
No you can not find that out. That file, might be even generated on the fly, upon http request to url with parameter download.php?id=312 as a response

Is it possible to send file from a local URL?
I need to upload files in php from your local url, eg I open the web page with:
www ... upload.php?url=c://...file.jpg,
from the url GET,I would get the file on the pc and would upload, without using html or anything else that I have to choose, just with the file url.
Important, it can only be this way, it will not be possible to choose the file during the upload, it will only be a POST or GET with the local url.
I researched and found nothing related, if anyone can help
I think it is impossible for server to get a client file by using the file path.
But maybe you can use JS and FileSystemobject to prepare the file, make it to streaming and post to the server.
And you must know FSO need a high security permission and may be disabled on users' browser.
I've got the following situation: I have some files with hashed filename on a cdn. Now I want a php script which redirects to the files (download) and give them another name. Is there a way without using readfile? The problem with readfile is that it doesn't make sense to download the file from cdn to my webserver and then download the file from the webserver to local computer.
Well, I got an API which read binary file from database and store it as "PDF" in windows temp folder, then it sends the path to that file to "PHP" page. What I want is to display that file over the browser.
The API returns the PDF file path: C:\Users\username\APPDATA\Local\Temp\some file.pdf. What I have done is setting that path to an iframe in my page,
but it shows nothing.
What am I missing here?
You should convert that local path to an url one.
Http://www.yourpage.com/folder_where_you_keep_those_files/file.pdf
And give the proper folder and file permissions.
The PDF is on YOUR computer, the user cannot access YOUR C:\ drive.
You cannot exchange your client-side files with someone server-side.
Store your PDF file on the server somewhere and set that path in the iframe.
You need to move that file from you local path (it can be your tmp folder or another folder that is not in your web accessible path) to your web directory so that you can put that in your iframe source.
Eg:
<iframe src="http://yourwebsite.com/somepdf.pdf" width="1000px" height="800px" >
I have a url that downloads a .csv file to my computer like this
http://oi62.tinypic.com/2nh0zzt.jpg
The url is
api.infortisa.com/api/Tarifa/GetFile?user=xxxxxxxxxxxxxxxx
But what I want is to download that file in a folder of the server, or at least open it's content so I can save it where i want.
(upload that file via FTP every time is a pain)
I can't access the direct url of the file, just what the api gives me, and that is just a direct download.
I tried curl and file_get_contents, but nothing seems to work.
How can I download that file in the server instead of my computer?
Any help would be appreciated.
So I am running xampp and wordpress. I have an image uploaded to the uploads directory named "avatar.jpeg". It displays just fine. But when I delete it and upload a new image file named "avatar.jpeg", the server doesn't reflect the change and just shows the old file. But when I open the file in Eclipse or my explorer, then the server starts showing the change and displays the new image.
This is probably something basic which I never learned about. I tried chmod to set the file permissions on the new file but that didn't help.
The file will be cached in your browser. To force a reload, append an arbitrary variable to your file, e.g. <img src="yourfile.jpg?1234567" />
I also guess it's a caching issue like freddy K. does.
I would suggest to configure ETags on your Server.
Simply appending something to the URL may only help you when the appended string is changing on every update of the requested file(using the current timestamp or similar all the time will force the client to download the file on every request and slow down the page).
