Flood Protection and Globaling

[Anon]

I'm building php-based flat-file forums and I'm having a couple of problems. First of all, I need a way of preventing a certain IP address from posting within a certain time period of their last post. This way the forums don't get flooded with posts.

My second problem is that I am trying to log the IP address of anyone who posts. I am saving the IP as the variable ${"IP$id$t_id$p_id"} where $id is the forum id, $t_id is the topic id, and $p_id is the post id. This works fine, however when I try to global it, it doesnt work. I dont know how to fix this problem. If anyone has an answer to either of these questions, or a better way of doing the IP logging, please reply. Thanks, Char.

For the first one, you can have a file that has the latest post timestamps. When someone posts, you check in that file if that person is allowed. If he's not, send an error message. If he is, then add him to the file. And after that, delete from the file the entries that passed the timeout.

What do you mean by you try to global it?

thanks for the first response, and for the globaling issue, when i do something like

global ${"IP$id$t_id$p_id"};
echo ${"IP$id$t_id$p_id"};

it displays nothing. The variable is not defined for some reason.

Could it be because
$id
$t_id
$p_id
are not defined in the function? 🙂

try:

global $id, $t_id, $p_id;
global ${"IP..."};
