how to grab part of current url and pass as variable

[swisslyons]

i am trying to integrate a flash image slider GUI into a dynamic site:

i need to be able to grab the id from a url like this:

index.php?option=com_hotproperty&task=view&id=1&Itemid=40

how can i get the id=1 part into my flash?

my swf will be displaying on this url... and additionally it loads a php file that does a sql select, formats xml and outputs the data back to the swf.

for live example of what I am working on:

the page where the flash WILL eventually be placed:

http://www.musci-immobilien.ch/index.php?option=com_hotproperty&task=view&id=1&Itemid=40


the temporary testing page with the id=1 hardcoded in for now:

http://www.musci-immobilien.ch/index.php?option=com_wrapper&Itemid=46


hope that i explained this clear enough...

can I parse the url of the ppage my swf is embeded on to get the id varaible that i need?

Can i use javascript to do this?

whats the way?

thanks in advance

OK when going on this php page holding the swf just pass the variable to flash using flashvars.
As you get the id already, you could simply do this
<param name="flashvars" value="&id=<?=$id;?>" />

and don't forget to put it inot the embed tag too like
flashvars="&id=<?=$id;?>"
