I do not think this is ever going to work because you will have problems retrieving posts that are related to the groups with the SQL query. Anyway, the file you should look at is at the following locations:

Group Blog App model file
/media/com_easysocial/apps/group/blog/views/groups/view.html.php

Editor
/components/com_easyblog/themes/wireframe/composer/panels/post/author/default.php

Kindly please do take note that we are unable to assist you any further as this is beyond the scope of our support. Thanks for understanding!

I see.
Thank you for your extremely quick response Mark.

Technically, for this to work, is that it would be complex to implement ?
With a lot or a few code customizations ?

Often times, you may think it is fairly easy but here are some of the complications that I can think of based on what you are trying to achieve:

1. For instance, how do you get posts from a group with the id of 10 if the value on the column is comma separated?

2. What about privacy of the group? Consider that you have Group A which is closed and Group B which is open. What if the post is posted on Group A and Group B with the idea that the post should only be viewable by group members only?

3. What if Group A is deleted? How are you going to handle the comma separated values?

Indeed, the constraints are numerous.
About that, I already mentioned a similar topic here :

I would like to have your opinion on this Mark, please.
The publication since the User's Story form in several Groups simultaneously, is it a realistic project ?

Because Irwin answered me this: "We will consider this."
I would like to know if I can hope to see this possible one day...

Thank you again

I do not have the definite answer for this right now but I really don't see it being feasible to post a blog post into multiple groups unless they all share the same privacy

In this case, the conditions would be that only Public Groups could be selected in the new Story Form.
The same publication/same id (Article, Photos, Video, Poll, etc.) would be displayed in the Journal of each selected group.

EasySocial 3.2 and EasyBlog 5.3 are probably not yet in development, so it's interesting to discuss this idea now

Facebook is a growing threat to us as independent social networks.
Facebook will allow soon to select the Group in which you wish to publish.

The simultaneous publication on several Groups would be a way to offer a feature that Facebook users do not have.
Thereby increasing the reach of their content and the interactions, through different Groups of different themes.


Philippe

There is a reason why Facebook does not have simultaneous publishing and it is probably because of these shortcomings that I have already provided.

Anyhoo, please feel free to post it under the feature requests area
