BuddyPress.org

I think you might find it is the user_login property has the value john.doe. I can’t remember where the hyphenated username is stored but try user_nicename instead.

The Restrict Usernames plugin is pretty cool actually. I’ve used it in the past. Aside from specifying illegal characters, it will let you reserve words you don’t want normal users to register. Site name, admin, help, support all spring to mind.

Settings > Email should do it. Alternatively you can go straight to the page via:

You’re not using the function I gave you right. There’s no need to use server variable or do a string replacement.

I believe bp_is_change_avatar() is what you are looking for.

The best place to learn how BuddyPress works is the codebase. Over the past few years, the inline docs have been improved tremendously and are now at a point where they’re very useful.

HTML

<button id="me">Click this button</button>

JavaScript

document.getElementById('me').addEventListener('click', function() {
alert('Hello');
}, false);

It’s fairly straightforward to do. See this demo. You could also use jQuery if you wanted instead.

I doubt there is a WP hook for that event; instead, you should use JavaScript for that.

That should be the hook to use. See here for it in context:

There’s something causing the registration form not to submit and that’s likely to be either a rogue plugin, theme or custom code you’ve introduced. The usual troubleshooting steps are to deactivate everything and work forward step-by-step, testing as you go. That’s the only way to determine where the problem has been introduced.

If that particular step creates a group, then the same hook (that I provided earlier) will fire.

Do you think Buddypress can support hundreds of thousands, if not millions of users?

In theory, yes, BuddyPress can handle millions of users. BuddyPress will add rows to the database without problem, and that database can scale to a very large size.

In practice, there are things that might have an impact on that. Your hardware will play a big…[Read more]

I’m not sure what you mean by create group form?

You could use a third-party library such as Masonry?

I even wiped my whole functions.php file…

I’m not sure you needed to do that if using TwentyFifteen because only the TwentyFifteen functions.php file will be in force.

Can you try on a test install? It may be the ACF plugin and we need to rule that out.

On your test install, be sure there’s no plugins running aside from BuddyPress and have the TwentyFifteen theme activated. Also, remove any custom code you may have elsewhere such as bp-custom.php

Personally I wouldn’t do that. The number of rows in the activity table can be big without problems. If you’re worried about bloat, you could think about limiting the number of characters accepted by the content field. The field is type LONGTEXT which I think means each item can be ~4GB. Some simple front-end validation limiting that to X…[Read more]

By post do you mean a WordPress post?

Can we search users who are not in the friendlist?

You can in the site search at example.com/members but elsewhere I’m not so sure. If there was a search box on a member’s profile page then I’d expect that to return that member’s friends only. It wouldn’t make sense to return non-friends. But that’s just my personal opinion.

Try disabling all plugins aside from BuddyPress. Sometimes a rogue plugin can interfere with the registration process.
