DESCRIPTION

A complete invites system for your vBulletin board.

STATISTICS

File Uploads: 3
Template Changes: 4
Products to Install: 1


FEATURES

Configuration Options:

• The system can be turned on and off.
• Registration can be set to either require invite code to sign up or to continue allowing regular registrations when the system is on.
• Invite Expiration Period.
• Minimal Posts Required to Receive Changes in Number of Invites.
• Minimal Reputation Required to Receive Changes in Number of Invites.
• Number of Posts Required to Get One (1) Invite.
• Number of Invites Received or Subtracted per Reputation (+ for positive, - for negative).
• Initial Number of Invites Given on Registration (Sign Up).
• Usergroups that May Not Use Invite Manager.
• Usergroups that May Use Invite Manager (Optional Override).
• Initial Registration Usergroup (only pertaining to registration by invites).
• Do or Do Not make users linked by an invite mutual buddies after the completion of registration of the person invited.
• Single / Multiple Address Line Field.
• If Multiple, Number of Fields to Show.

Miscellaneous Features:

• Upon invite-based registration, the person who issued the invite is set up as a referrer of the person invited. Therefore, free specification of a referrer is restricted during such registration.
• Image (GD) Verification.
• Administrator can manually edit any user's invite count.
• If a user is permitted to issue invites (based on both the number of unused invites and the system permissions), that user has a link to invites of usercp home (says "Click here to invite new users!"). When a user has no invites left, the link does not show up. Nevertheless, as long as system permissions allow access to the Invite Manager, the usercp navlink continues to show up, so that the user would have access to his/her invite history, which is available just below the "Issue New Invite" form.
• If registration is set to require invite code to sign up, the navbar register link becomes hidden.
• If registration is set to continue allowing non-invited sign ups, the number of invites available to any single user is unlimited. Therefore, the number of invites left does not show up.
• Invite History in UserCP, on the bottom of the invite manager.
• Single-Line AddressField, with Unlimited # Of Simultaneous Recipients, within the bounds of invite tokens.
• Multiple-Line AddressField, with Limited Configurable # Of Simultaneous Recipients, within the bounds of invite tokens.
• Unregistered Users, Banned Users and Users with No Forumview Permissions cannot use invite manager. Therefore, you do not have to specify those usergroups in the list of usergroups that may not use the invite manager.
• Invite counts are automatically updated once a week, based on the admincp-configured settings.
• Per-user invite usage restriction.
• Inactive users, who do not post anything new, will gradually lose all of their invites.

IF YOU LIKE MY HACK, PLEASE CLICK INSTALL

[cat_aclysm]

I'm new to vbulletin, so please be gentle with me if I did something stupid here. I installed this exactly as specified, but I hit "run now" for the update invites count" in the scheduled task manager, and got this error:

Warning: Division by zero in /includes/cron/update_invitecounts.php on line 79

It hasn't given any invites out at all. What did I do?

[opteek]

download the hack again and reupload the file update_invitecounts.php

Thanks, but I allready did that twice and got the same error. :disappointed:

[opteek]

Do you have 0 set for number of posts to recieve 1 invite? That would do it.

That would be a really stupid mistake, wouldn't it?

That is exactly what I did. :speechless: Thank you for helping.

Edit, oops, I made sure nothing is set to zero anymore, and I am still getting the same error. Apparently, that wasn't the fix I needed.

[IrPr]

works on 3.5.3 ?

[IrPr]

i upgrade my testboard to 3.5.3 and mail function is working
but invite mails not working
i donno maybe im too newbie here and need surfing forum more

Edit: works fine on 3.5.3

[opteek]

Is no one else having this problem with people getting too many or negative invitations?

[akanevsky]

Negative invitations are by design
As for too many, you need to set up the minimum amount of reputations and/or posts to receive new invitations.

[opteek]

Look man, I do have the settings configured properly. My settings are:

Invite System: Enabled
Registration by Inivites Only: Enabled
Mutual Buddies: Enabled
Image Verification: Enabled
Invite Expiration: 7
Min Posts to recieve changes in invites: 24
Min Reputation to Recieve Invites: -1
Invite Changes on Reputation: 1
Posts required to recieve One invite: 50

Now, people who have more than 24 posts are recieving 7 invites, when they should be recieving zero. This is due to your code, which starts invite_increment at 7 and subtracts 1 for every day inactive. So people that are active every day, yet make no posts or have any reputation changes are recieving 7 invites!!

Also, the user who recieved -11 invites had 3 posts in the last week and had NO reputation changes.

This is obviously not right; I have redownloaded your update_invitecounts.php file and verified that I am using the exact same file...
