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.
