How to add IP address & hostname to admin registration notify email

[f150guy]

I know that I have to edit the "email_newuser" template, but what variables should I use to have the new users ip address & hostname included in this message. I find this information very helpful when troublesome users insist on re-registering after they have had their posting rights revoked.

$REMOTE_ADDR and I can't remember the hostname variable (if there is one) -- you might have to gethostbyaddr() the $REMOTE_ADDR to get it.

That did it...

Thanks Ed.

Since my server is set up to resolve host names, the two variables are:

$REMOTE_ADDR and $REMOTE_HOST

Does that mean that I can use any environmental variable in vB templates in this manner?

[Mike Sullivan]

In most. You might have to use $GLOBALS[REMOTE_ADDR] and $GLOBALS[REMOTE_HOST] in a few. (Not 100% if those work -- haven't tested them).

My server is set not to reverse-lookup (it's supposed to add extra strain to the server, so I didn't enable that bit).

If yours is like mine, then don't worry - follow these steps to hack this functionality in. Don't forget to take a backup of register.php before you edit it.

1. Open register.php
2. Search for eval("\$message = \"".gettemplate("email_newuser",1,0)."\";");
3. In the line immediately above it, add:
$hostaddress=gethostbyaddr($ipaddress);
4. Save, close and upload register.php
5. Go into your control panel's templates and edit email_newuser
6. Add the following lines where you want them to appear:
IP address: $REMOTE_ADDR
IP host: $hostaddress
7. Hit "Save changes".

Hey presto; you'll now get the IP address and the hostname in your registration e-mails.

I've documented this here primarily so that I don't fall into the trap of hacking code and then having awful problems putting undocumented hacks back into the upgrade, but I hope others find it useful (and that I've not broken any rules!)
