I'm trying to do a realtime commenting system.
I have this place for comments in posts, and I want the new comments
to display automatically in the comments area, with reloading the
page.
I have this that check if there are new posts after the page is loaded
every ten seconds:
setInterval("ajax('{{=URL(r=request, f='last_comments',
args=post_id)}}/{{=time()}}', ['comment'], ':eval');", 10000);
I then use request.args(1) to query the db if there are post created
after the load.
But if it finds a new post, i have to save in the session the new time
for cheking..
It works well, but i need to have the post_id in the session variable,
because if the user as 2 posts loaded, I want the correct comments to
be displayed in the correct posts.
I don't know if this is the best way, if you any other option please
let me know.
