Php – Get info after fileReference upload

actionscript-3file uploadflashPHPupload

Normally when I send information to PHP scripts via URLLoader, I have the PHP return various success codes so I can have my Flash files respond according to whatever success code the PHP returns (0 is a failure, 1 a success, 2 is some other error code, etc.).

Now I'm trying to submit a form with a bunch of data in it (name, email, birthday, etc.) as well as upload a file. I'm using fileReference to upload the file and send the additional variables along with the upload request. The information is making it to my PHP file fine. However, I can't find any way to get information BACK from the PHP file. That is to say, I want the PHP to echo "success=1" if the file is successfully loaded, "success=2" if there was an error inserting the data into the MySQL database, etc., but currently I can't figure out how to get info from the PHP. Normally I could just look at _myURLLoader.data but in this instance I need to reference _fileReference.data which is actually the bitmap data of the file.

Anybody have any ideas?

Thanks!

You can use the http status to tell flash what happens when you upload a file.

On the php side, to tell flash the file was not received I do the following:

if(!isset($_FILES['Filedata']['name']))
{
header("HTTP/1.x 500");
print "RESULTS=FAIL";
exit();
}

If the file is larger than what I want:

if(!isset($_FILES['Filedata']['size']) > $maximumuploadsize)
{
header("HTTP/1.x 406");
print "RESULTS=FAIL";
exit();
}

Etc.

Then on the flash side I'll setup an .onHTTPError listener such as:

photo.onHTTPError = function(file:FileReference, httpError:Number)
{
switch (httpError)
{
case 500:
// Handle missing file
break;
case 406:
// Handle file too large
break;
}
}
