Signup from U.S. ip's only ... Is it possible?

TxFestus - July 9, 2007 - 00:22

Hello all, I have a question about signup limitations/restrictions.

I have been testing Drupal and WordPressMU for my new ".us" site. I'm almost sold on using Drupal at this point. The only question I have is about a plugin. There is a 'widget' for WPMU that restricts a signup based on the users IP country code. Is there such a thing available for Drupal?

In general, if a user comes to the site from an IP that has a U.S. country code then they can sign up. If their IP indicates they are from another country then they get an error message stating that signups are intended for U.S. users and that their IP indicates that they are from "country code ##". The error then instructs them to email admin with information to have account manually added in case of errors or whatever.

I'm setting up a ".US" site for "patriotic bloging" and just wondered if this is possible.

I have nothing against the other users in other countries, but wanted to make this a "U.S." blog portal if possible. At this time I just don't see a lot of users from other coutries wanting to come by and join a U.S. Patriotic blog site, but I may be wrong.

Any ideas, suggestions or comments are appreciated.

Thanks

ps, I'm a Drupal noob so be nice.

Have it converted

If you can get that widget, you can convert it, or have someone else convert it. It may not be terribly complicated.

Who is your target audience?

You may wish to consider who you are filtering out/allowing in with a geographic filter. Not a Drupal thing, more matter of strategy for your site and/or organization.

It is your site, so do as you wish, but there are a "few" people not residing within U.S. borders that may wish to participate in such a "patriotic" site; military, global affiliates, people on long-term assignment, "friends," etc. Granted, if none of your target audience ever leaves the country, then this is a moot point.

Good luck!

Hi, thanks to both of you

Hi, thanks to both of you for replying.

As far as target audience .... open. I understand the need to allow people outside of the us to signup, but that could be done manually if need be using the stock error message the script maker uses.

The plugin (php code / more of a filter actually after I went back and downloaded it) is located here http://mu.wordpress.org/forums/topic.php?id=5508. The download consists of a php page with script and that's it. No real instructions on where to place it. I'm guessing somewhere at the top of the signup page.

If you are not accessing their site from New Zealand then you can go here and see the end results of a "non" country trying to sign up .... http://blogtown.co.nz/wp-signup.php

I'm also including the php code here for reference to make it easier for help.

In searching I also found this site (http://webnet77.com/scripts/geo-ip/index.html) that has an IP to country database that can be used. Don't know if maybe the two together could make what I'm wanting.

In searching the above I found this in their forum about what their scripts would need to capture the IP of a visitor. Thought it might help someone who may be looking into this.

Thanks Nancy for even giving this a shot. I really appreciate the effort.

I'm also open to other ideas if anyone has any.

thanks again

Still working on it

I've had a few problems with the database not wanting to load, but I got past that.

More info for possible helpers ...

TxFestus - July 14, 2007 - 23:05

Here's some more ip to country information (along with a downloadable database file) that I found.
It might help give a new idea or approach to the wanted goal.

thanks to all who takes the time to work on this.

ip2cc module

sugree - July 17, 2007 - 04:39

You may use ip2cc module and below snippet to validate incoming user in registration form.

<?php
$allowed_cc = array("us");
 
$addr = $_SERVER['REMOTE_ADDR'];
$country = module_invoke('ip2cc','get_country',$addr);
if (isset($country)) {
  $cc = strtolower($country->country_code);
  if (!in_array($cc,$avail_cc)) {
    form_set_error('country',t('Your country are not allowed to register on this site.'));
  }
}
?>
