send data to a specifi user

abagaglia

Lately I was wondering on how to send a specific message (via browser window) to a logged user.

1) The user logs in my service.
2) I recognize him and get his IP.

I need to send him a new window but i don't want other logged user to get the message.
Does anybody know a way to accomplish this?

Hi Alex,

To send the user to another window, simply send a HTTP header request, such as:

Header: "Location: http://www.domain.com";

You can get the IP address by looking up the REMOTE_ADDR variable (using getenv()). If they're using a proxy server, like most dial-ups, you should test for HTTP_X_FORWARDED_FOR aswell.

Thank Dave, but that way you would send a message (in the shape of a popup window for example) to anybody.

Consider this:

Ten people login to my website and I register their IPs.
At a certain time I want to send a popup window to 1 of those users (the others shouldn't receive the message).

Do you know a way to do this?
(which is to say you decide who gets what)
thanks

Alex,

You'd have to query the user to find if their IP address matched the one you wanted to target, such as:

if ($REMOTE_ADDR = "62.149.146.226") {
}

You can't instruct the browser to deliver a pop-up window using PHP, so it'd be better to set a javascript variable using PHP, like so:

Cheers,

Thanks Dave, guess that would do.
