Hi,
I have not worked with RAW_POST data - just the $_FILES array in
PHP, but allowing people to set the path that a file is uploaded to is a
huge security risk - imagine someone uploaded a dodgy PHP script that
was inside your webroot and then called that script??? File upload is a
dodgy game and I would recommend posting text in a request variable,
along with a relative path, then saving that to a known file outside
your http root - you can always have an admin script to approve images
and stuff like this later.

Hi, sorry if this is a PHP question....I'm trying to work with this
more on the Flash side, so I hope its a Flash question.
I have a PHP script online that serves to write binary image data from
my Flex/AIR app:
$f = fopen($path,"w"); fwrite($f, $GLOBALS[ 'HTTP_RAW_POST_DATA' ] );
fclose($f);
On the Flash side:
var jpgtosave:JPGEncoder = new JPGEncoder();
var rawdata:ByteArray = jpgtosave.encode(bitmap);
var header:URLRequestHeader = new URLRequestHeader
("Content-type", "application/octet-stream");
var myRequest:URLRequest = new URLRequest (path);
myRequest.requestHeaders.push (header);
myRequest.method = URLRequestMethod.POST;
myRequest.data = rawdata;
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.BINARY;
loader.load(myRequest);
This works great, but now I want to use that same PHP script to upload
a text file. The reason I want to keep the PHP script the same is
because the end user actually sets the upload location, and I think it
would be overly complicated to have them choose two different upload
script locations.
Anyway, no matter what I try, the text file that's written to the
server is done correctly, except the contents of it are always the
file's URL instead of the text that I wanted. I realize there are
better ways to upload text through PHP, but as I said, I'd like to use
the same script as my JPG uploads.
Here's some things I tried:
1. Changing the request header to "Content-type", "text/plain"
2. Changing the URLLoaderDataFormat to TEXT
3. Writing out my text's string to binary through ByteArray.writeObj
4. Taking my binary data directly from a FileStream
So, as you guys can see I'm stabbing in the dark! I assume that I'm
somehow encoding the data wrong to get to the server. Maybe I need a
file header as the com.adobe JPGEncoder gives the JPG a header,
likewise I should give my text file a header. Does it have to be
binary data to use with my PHP script?
Thanks!
