well, hard mods will be able to solve those "spammers" ^^

Stefan, is there a way to have this go by the user's timezone time instead of the server time? I noticed a user doubler-posted the other day and the time was 2 hours behind the actual double-post (the server is set at PST and I am in CST).

as posts are stored in server timezone as well as the timenow variable which is used for the hack, it's not possible.

Or better, wouldn't make sense, because if you would base it on usetimezone, then it would be possible that one user can post every minute while the other must have to wait nearly a whole day until...

But shouldn't it at least be ahead of the post time itself? This was almost 2 hours before the actual post time of the message.

i think either you or me is confused now.

everything has to be based on TIMENOW as that's the value stored in the DB, and used by the phpscript.

so the hack works absolutelly correct.

if you get wierd behaviours, that could mean, that you have another hack, which manipulates the times or, a slight server problem with different times on different servers..

Great hack!

Well since i don't (sorry enough) have mods online 24/7 ....

Could you please do the code change or look at it if it's not too much trouble.

If one wanted to incorporate checking of the title to validate double posting, how do you compare the title from the last post to the new post.

I want to prevent users from posting two books of the same title (the book title is part of the post title).

Thanks

the value is stored in $post[title]

@leeman: sorry, i'm very very busy and cannot help you right now.

Great hack, thank you!
By the way, does this hack update New Posts list when someone is doubleposting?
