[Flashcoders] Uploading different types files to a PHP script
Hi, sorry if this is a PHP questionI'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!

Re: [Flashcoders] Uploading different types files to a PHP script
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.

Re: [Flashcoders] Uploading different types files to a PHP script
Hi Glen,
I posted this yesterday, and didn't get any flashcoder emails
yesterdayso I was hoping I was ignored!
I figured out my problem, and really it was me being an idiot. I
actually got text and images working, but when I went to the URL where
my text file was at, it just spit out the URL of where my browser was
pointing. I guess I should have actually checked the content of the
file through FTP, because it was working just fine all alongI guess
my browser doesn't understand the file I uploaded to be text...or something.
Anyway, yes, I'm aware of the security risk, and this is for my personal
websitewhich barely even registers in google, so I doubt there will
be any attacks. Once I get my test working and my website online, I'll
probably have some sort of password protection and file filter type of
thing only letting you put up certain types of files.
Thanks!
