Share only to one specific blog

I think your use case would be best solved not giving users access to each others blogs, and some code snippets. Like these two, for example:

https://broadcast.plainviewplugins.com/snippet/add-access-to-a-blog/
https://broadcast.plainviewplugins.com/snippet/remove-access-to-a-blog/

Removing the user’s write access to other blogs you can do without any add-ons. ??

Thank you very much for the quick answer!

This seems to be exactly what I need thanks. But I seem to have trouble when I want to remove more than one blog (since I only want to show my “main-blog”).

I tried something like this so it would remove new blogs automatically.

$blog_count = get_blog_count();
for ($i = 2; $i <= $blog_count; $i++){
     $action->blogs->forget( $i );
}

I also tried to just remove them individually like this

$action->blogs->forget( 2 );
$action->blogs->forget( 3 );

But with either solution I don’t get to broadcast anything anymore. So sorry for the bother but how would I go about to remove all blogs but the first for every user?

First, is no “first” blog for any user. Blogs are not ordered at all, other than by date of creation.

Second, you can’t just forgot 2 or 3 if those are not the blog ID numbers. You have to forget the exact blog IDs in order for them to disappear.

Try foreaching the $action->blogs array and removing the IDs found in there.

Thank you for the answer. I’m aware of that but my test-blogs do have the ID’s 1, 2 and 3 (see the screenshot here)

So I can try with the array but the result in terms of ID’s should be the same. I write tomorrow as soon as I have tested it.

Thanks very much for the support =)

Sorry for the late return. I was a bit occupied the last days but tried several things – unfortunately none of which worked. I’m pretty sure it’s my error but I have no idea what I am doing wrong and I would hate to search for a different solution as broadcast would be perfect in any other way.

So I’m just hoping for a bit of help from anybody =)

I have a test-site with four blogs (ID’s 1, 2, 3 and 5). The users from blog 2, 3 and 5 are only allowed to broadcast/share their posts to blog 1.
So I tried removing the access to blog. For example the following:

function my_threewp_broadcast_get_user_writable_blogs( $action ) {
$action->blogs->forget( 2 );
$action->blogs->forget( 3 );
add_action( 'threewp_broadcast_get_user_writable_blogs', 'my_threewp_broadcast_get_user_writable_blogs', 200 );

It works perfectly. From each blog-backend I can only choose blog 1 and 5 to broadcast. But as soon as I add the last blog to forget:
$action->blogs->forget( 5 );

It doesn’t work anymore. I’m unable to broadcast any post from any blog-backend. Does anybody have an idea why that is or how I could work around that?

Hm. Very weird. The broadcast box not appearing is due to the user not having any access to any blogs, but all users from 2 3 and 5 should have access to 1, right?

If the users of blogs 2 3 and 5 have access to at least 1, then the Broadcast meta box should be visible.

Exactly my “final” code ist just this:

$action->blogs->forget( 2 );
$action->blogs->forget( 3 );
$action->blogs->forget( 5 );

This should have left blog 1 open to everybody but the broadcast box is not appearing. I also tried to add access specifically for 1 but it doesn’t change anything.

Weird. Could you e-mail me at [email protected] so I can take a look for myself?
