Hi,

I have an upload application written in PHP and Flash. The PHP page
gets the file information via $_POST. Moreover, the user never
actually visits the PHP page, rather Flash sends the information to
the
PHP page and then loads the result, all in the background. Right
now,
the php page cannot access the $_SESSION. Is there anyway that I can
conitnue the PHP session when doing this or does the user have to
visit
the PHP page?

Thanks.

Steve


Looks like your flash isn't sending the session cookie along with the
rest of the request.

Do you have an idea how I can get flash to send the session cookie?


I think you're going to have to ask that in a Flash newsgroup. We're
PHP programmers here.

I definitely know how to pass the session_id via flash. I guess I
should have asked how do I manually set the session_id value in PHP?
In other words how do I populate the session_id variable?


You don't. PHP does, based on the session id passed back by the
browser - which is stored in a cookie.

I beg to differ:

Do something like:

<?php
ini_set('session.use_cookies', '0');
session_start();
?>

Put your flash movie in the same page and echo the SID behind it (old
school style):

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0";
width="32" height="32">
<param name="movie" value="whatever.swf?<?php echo SID ?>">
<param name="quality" value="high">
<embed src="whatever.swf?<?php echo SID ?>" width="32" height="32"
quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer";
type="application/x-shockwave-flash" sid=""></embed></object>

This will give you access to the variable PHPSESSID in flash. Make sure
you append this to every GET request to php.

Notice though that appending session ID's to GET request are often
considered a security risk. But since you are using flash and thus
requests are made in the background (not through addressbar requests),
it's somewhat safer to use IMO.

Ooops I didn't thoroughly read the whole thread. I didn't read that a
session was already started.

Forget about the ini_set('session.use_cookies', '0'); part.

And do (untested):

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0";
width="32" height="32">
<param name="movie" value="whatever.swf?PHPSESSID=<?php echo session_id()
?>">
<param name="quality" value="high">
<embed src="whatever.swf?PHPSESSID=<?php echo session_id() ?>" width="32"
height="32" quality="high"
pluginspage="http://www.macromedia.com/go/getflashplayer";
type="application/x-shockwave-flash" sid=""></embed></object>

Then in the php page that handles flash requests:

<?php
session_id($_GET['PHPSESSID']);
session_start();
?>

Should do the trick. But maybe I'm overlooking something here.
