How can you make a form (outside the forum's directory, but still in the same domain) which can register a user to the forum?

Do you write the sql query on the target page (a page where you'll be redirected to when you clicked submit')?
Or?

the form and queries can be on any page you wish, anywhere in the site, just as long as they query the right database.

I'm still a little confused with what query to enter and how would I make a similar form (other than copying from the HTML source code).

There's a long script (with some queries) in register.php, but I don't understand how to implement such a long script.
Can I use require() or include()?

just include it (and the form to save recreating it)

(moving this to PHP forum)

well, if I include it I think there'll be problems if I include it because register.php also has includes (so I need to change those paths, or else the script wont work, will it?).

And I can't find the registration form HTML code anywhere in the forum folders.

Pretty fustrating.

(so I need to change those paths, or else the script wont work, will it?).

No or is that yes??

Just include it. If the paths are ok now they'll still be ok

Sounds to me like you need to develop an API for the various sites, so they share a user database.

I got it. The solution: IPBWI, JFussion, etc.

To create an external registration you just need to include 'a file' from the Integration package then it'll do its magic.
