I'm looking for a BETA testing invitation script. Basically so some people can register and test the site.

Example:
1. You give email
2. We might send an email back saying congratulations, click this link (www.domain.com/invite/accept?j343g4hn454j5b) or whatever.)

Preferably Open source but I'm up for anything right now. Heard PHPList could do it but not to the extend I need.

Thanks in advance

If you're just looking for a pre-built script, try google. Terms like "PHP eMail verification" or "PHP user registration system" will work.

If you want help with code, you'll have to be more specific. The best I could give you is the basic logic of the sytem:

A. Request user's eMail address via form
** 1. Validate eMail address is in proper format
** 2. Validate that domain name as a responsive MX record
** 3. If either fails, return to [A] with error
** (Note) A CAPTCHA would be good to have here.
B. Display verification instructions (send email, ask user to check eMail)
** 1. Store random string, with eMail address request in database or similar
** 2. Send eMail to user including randomized code. A simple link makes life easy.
** 3. This page could also host a form requesting the user to enter the verification code you just sent via eMail if they opt to copy/paste the code instead of clicking the link you provided via eMail -- the form would be submitted to [C] (below)
C. Auto-click verification script.
** 1. If both eMail addres and random code are supplied, ensure they match in the database, then grant access.
** 2. Otherwise, provide further instructions / error message.

Well I would prefer something to integrate with Joomla! CMS. On another note, believe me, I've tried google
Thanks for the logic though.

Thing with google is it's all about picking the correct keywords (Most of the good stuff is SEO'ed badly).

Have you ever considered getting it custom coded? I assume something like the above should be under £50.

I have but I would prefer to see it online, learn from it and then put it to practice. I've done a lot of scripts in my time. I created one or two, but sending out a random code for their specific email and then linking it with a joomla! CBME was the tricky part. I currently just have an email system in place and I'm generating them by hand :P

Thanks for the reply.
