Forms and IP addresses

ironinthesoul

We have a form on our site used by our administrators that contacts another site using an HTTP GET. This site then checks the IP address of the sender, if its OK it processes the request.

Easy so far. However, we have people logging in remotely with all sorts of dynamic IP addresses.

So, how can I get our server to send the request rather than sending a header (Location: ....) back to the client so it sends the server IP rather than the client IP.

Hope this makes sense. I'm confused and I wrote it!

well the code is always easiest to explain when you have code to show it in....

replace the $SERVER['REMOTE_ADDR'] (I believe thats it) with the ip of the server... or possibily $SERVER['HTTP_HOST']

OK, here is the code:
$var_a = $HTTP_POST_VARS["var_a"];
$var_b = $HTTP_POST_VARS["var_b"];
$var_c = $HTTP_POST_VARS["var_c"];
$var_d = "var_d";

header("Location: http://000.000.000.000/action?$var_a=".$var_a."&var_b=".$var_b."&var_c=".$var_c."&var_d=var_d");

Of course, the server sends the page back to the client which then processes the header() sending its own IP address.

I don't want the page sent back to the client. It must get to 000.000.000.000 with the servers IP not the clients.

Hope this helps.

Maybe I dont quite understand... but you want a website that say I load... and submit a form on to appear on another IP's monitor? (or by how do you mean "back to the servers IP" Database?)

I guess being a bit out of my depth here doesn't help, but here goes:

Joe, who is at home dialling into an ISP that dynamically assigns IP addresses, goes to a form on our website, fills it in and sends it. The process page sits on our web server. It takes the variable and send the result on to a third party site which does some stuff. But the third party site requires a pre-determined IP address to validate the request.

If my code (see above) does the work, the request is not sent directly to the third party site with my (valid) web server IP. The form is sent back to the client with the modified header which then sends the request on to the third party with the client's (unvalid) IP.

So, rather than using the header() function which sends the form results back to the client and so uses the wrong IP, I want the

http://000.000.000.000/action?$var_a=$var_a&var_b=$var_b&var_c=$var_c&var_d=$var_d

to come directly from my webserver with its valid IP address.

Hope this makes more sense. If not, I'll try to be clearer.

Hmm...sounds like you need to be looking into the CURL library.
