Group-based site questions

Hi.

I need to build a group based website.

First question: is it possible to add a Group field to profile, and have the user choose the group he wants to join upon registration? 

Second question: members approval is subject to moderation, and the group admin should be able to approve the user, not only the site admin. Is this possible?

Other than this I need to have group specific applications, like pictures and events, but for these I found some modules on the market which can serve on my purpose.

Any help is welcome.

thanks

The answer to the second question is yes.  Please note that the owner of a group has to join the group as well.

There are some excellent group based modules in the market; I have a few of them on my site.

Answer to the first question is also "Yes" - with a bit of tweaking. If it were me - and this is just a quick thought; not knowing exactly how you are going to set things up. But,

Using the Profiles builder, create a field called Groups on the join and edit profile pages. Then, add a db query (not exactly sure where as the Group Add page is referencing other modules because of the uploads) that would insert the "Title" of the group into the sys_pre_values table. Something like:

INSERT INTO `sys_pre_values` (`Key`, `Value`, `Order`, `LKey`) VALUES ('groups', $Group_Title, '0', $Group_Title);

The goal would be - when a user adds a new Group, it is added to the Predefined Values table so that it can be used on the join form.

Again, I have no clue what your ideas are, but this is just a brief thought on how you can achieve something.

I don't know if I correcly explained myself: system users' join should be approved by group admins. In my Dolphin config I have configured user account to be subject to moderation by an administrator. I'd like to delegate this approval to group admins. 

Is this really possible?

Can you point me to some of the extensions you mentioned? thanks

When creating a group, there is an field called "Join Confirmation". If you select "enabled" for this then the Group Admin has to manually approve fans before they become members of the group.

Regarding modules, you can check out my Premium Groups which is an extension of Groups with many additional functionality such as Group Events, Group News etc.

AndrewP also has a bunch of group related modules.

Hi. Thanks for your suggestion. 

Indeed something like this could work, but I'd have to manually update the sys_pre_values table when a new group is added... But that could be a solution. I was wondering if it was possible to create a field with a direct reference to the groups table, but in some way this could work. thanks

What I need the most is to approve the user on the system, not only the user becoming fan of a group. As I said user subscription to the system is moderated, I'd like groups admin to be able to approve users.

Are saying you want Group Admins to approve new members who join the site ? If this is what you want, it will take some amount of custom coding so you may want to post that request in the jobs section. There is nothing like that in dolphin, neither are there any mods in the market place that will offer such functionality.

You could always get the Multi-Admin module that is in the market. The make the people you want to be group admins into site admins but lock everything out for them except groups using the module???

There is a mod that allows your members to choose the group they want to join upon registration. See http://www.boonex.com/m/auto-join-group
