Maximum Number of Groups was created by MarlonFungai

I want to implement a maximum number of groups in a specific category of GroupJive groups for a user. The use case is that we have groups that represent students from different universities and each student can only be a member of 1 university at time. How could I go about this?

You want to limit the number of groups they can join within a category or number of groups they can create within a category? There isn't functionality of either out of the box, but both are doable using CB Auto Actions. Will provide examples once you confirm which you're needing.

Ok, the below should be able to do that. It'll interrupt the join process if they've already joined a group in a specific category.

Global
Triggers: gj_onBeforeJoinGroup
Type: Code
User: Automatic
Access: Everybody
Conditions
Field: Custom > Query
Query:

SELECT u.`id`
 FROM `#__groupjive_users` AS u
 INNER JOIN `#__groupjive_groups` AS g
 ON g.`id` = u.`group`
 INNER JOIN `#__groupjive_categories` AS c
 ON c.`id` = g.`category`
 WHERE u.`user_id` = '[user_id]'
 AND c.`id` = CATEGORY_ID_HERE

Operator: Not Empty
Action
Method: PHP
Code:

$variables['var1']->setError( 'You have already joined a group in this category.' );

Replace CATEGORY_ID_HERE in the query condition with the category you want to check against. You can adjust the error message to whatever you'd like it to say. There isn't a way to suppress the display of the join button though. Can consider adding a way of doing that to GJ if necessary.
