Still not worked, but I found out a not too elegant solution. As far as I understand there is an order how the hooks run. There is a hook in class-buddypress.php add_action( 'bp_core_signup_user', array( $this, 'subscribe_from_form' ), 10, 4 ); so I added to my hooks 11, 4 so this is my code now:

function xprofile_sync_wp_profile2( $user_id = 0 ) {	
	
	
	
	// Bail if profile syncing is disabled
	if ( bp_disable_profile_sync() ) {
		return true;
	}

	if ( empty( $user_id ) ) {
		$user_id = bp_loggedin_user_id();
	}

	if ( empty( $user_id ) ) {
		return false;
	}
    
    global $wpdb;
	
    // Get name from x-fields
    $display_name = xprofile_get_field_data('Név',$user_id );
    

    $wpdb->query( $wpdb->prepare( "UPDATE wphu_users SET display_name = '%s' WHERE ID = %d", $display_name,  $user_id ) );
	
	
}
add_action( 'xprofile_updated_profile', 'xprofile_sync_wp_profile2', 11, 4);
add_action( 'bp_core_signup_user',      'xprofile_sync_wp_profile2', 11, 4);
add_action( 'bp_core_activated_user',   'xprofile_sync_wp_profile2', 11, 4);

And fortunately it works now 🙂 I don’t know if this is a correct way, but work, so I’m okay with it.

So, it seems that I’ve done it!
Thanks shanebp for the tip.

Here’s the code of function for changing display-name:

add_action( 'bp_core_activated_user', 'change_user_defaults', 99, 3 ); 
function change_user_defaults($user_id, $key, $user) {

    if (empty($user_id)) {
        $user_id = bp_loggedin_user_id();
    }

    if (empty($user_id)) {
        return false;
    }

    $mv_first_name = xprofile_get_field_data(26, $user_id);
    $mv_last_name = xprofile_get_field_data(11, $user_id); 
    $name = $mv_first_name . ' ' . $mv_last_name; 
    
    
    if ($name !== ' ') {
        $args = array(
            'ID' => $user_id,
            'display_name' => $name
        );       
        wp_update_user($args);
    }
}

update:
hmm i dont know. but it seems like the $user->errors is empty with var_Dump. but with print_r not.

also in the backend the user is activated when he clicks on the activation link. but $user->errors will give an error.

error_Log:

Are you sure I edit this in my theme? Or do I go into this instead? bp-templates/bp-legacy/buddypress/members > activate.php

Hi

Thank you for the quick response.
The question is which plugin?
I tried deactivating a couple starting with Aksimet and when I reached bbforum & buddypress & deactivated both: the pink background of the “Spammer” user disappeared, as well as the link “Extended”. They both do not reappear with bbforum activated. (See screenshot)
That made me assume it’s Buddypress that’s responsible for this pink background and the Extended link.
Moreover it’s under “Extended” edit of User on “wp-admin/users.php”, that one gets the status shown and where one can change from Spammer to Active, which will not work.

So just wondering … Or may be I’m just overlooking something obvious?

Regards

Well, it sort of half works now.

So I already had installed wp mail smtp, got all that setup…
So then I updated the buddypress plugin with the newest version that I think dropped today.
Then I installed wp better emails, reinstalled/reinstated emails in tools->buddypress, and the activation email thing works.

The only issue I’m having now is that I can activate the account, but I can’t login because it says that the password is incorrect, even though it isn’t. So that’s progress anyway.

But I’m not sure what to do now.

So if I go to the login area of my site, I enter my username and password, and then it sends me to a default WordPress login page. So I enter the info again, and it says that it’s the incorrect password. Should I basically be logging in twice like that? Once on my site, then once via the default WordPress login, only to be denied access?

I am reposting the same with the code parts fixed (I hope)

Wordpress Version: 4.9.6
Buddypress version: 3.0.0

Hello,

I’ve been struggling for days with oEmbed, but I’m not a coder nor very experienced in WP so no luck yet. I want to be able to post on the activity stream from almost any source and generate a preview (same as on Facebook, Tumblr etc). First of all, even some major sites (Facebook, Flickr, Tumblr) from the WP whitelist do not generate a preview when posting a link in activity. A bug maybe? Also, Activity Plus and rtMedia are not solutions, because I tried them and both have problems. I should point out that I have multisite and BP Multi Network and have set BP_ENABLE_MULTIBLOG as true.

Two very good plugins are Iframely and Embedly. The problem with the first is that there’s a limit of embeds in the free version and it doesn’t support as many sites as I need. Embedly does, but here’s the problem. When activated, there seems to be a conflict with some of the default embed providers of BP, like Vimeo and Youtube. A preview is still generated, but it is only a dead image of the video. You cannot click play or click on the title and open the video in a new tab. So the plugin becomes essentially useless (nobody could afford to have a social network where users can’t post YouTube videos). There’s a similar problem with Iframely (the YouTube video is OK but there’s a big blank area beneath it), but they have an option “Do not override default embed providers” that solves the problem. Unfortunately Embedly doesn’t have such an option. Does anyone know if I could force it somehow to do the same? (I have already contacted their support days ago but they never answered.)

Then, I thought to remove YouTube from the oEmbed providers list with

<?php wp_oembed_remove_provider( $format ) ?>

hoping that this would eliminate the conflict, since Embedly alone would handle YouTube links. I’m not sure what I did it wrong, because at first I pasted this code as a test:

<?php wp_oembed_remove_provider( 'http://wordpress.tv/*' ); ?>

in the wp-includes/media.php file at the end and it returned syntax error, unexpected ‘<‘. Then I tried:

wp_oembed_remove_provider( 'http://wordpress.tv/*' );

No error this time, but nothing changed. I could still post a link from wordpress.tv and a preview was generated. Can someone explain how to do this correctly? And do you think that if I remove YouTube from the providers it will solve the issue?

Finally, I found out about oEmbed Discovery. The documentation is not very clear, so I’m not even sure what exactly it is supposed to do if enabled. Does it allow content from any site to be embedded? Or does it have limitations too? And what does it mean “you can give unfiltered_html users (Administrators and Editors) the ability to embed”? If I used it, would I have to give every new user editor role so that they could post? Anyway, the thing is I installed the Enable oEmbed Discovery plugin, but absolutely nothing changed. I tried some test posts from various websites and only the link was posted as usual. Any idea what went wrong?

I tried all the above with network activation, per site activation, network and per site together, everything… but to no avail. Any help will be greatly appreciated because this is a huge problem for my site. Sorry for the long post, at least I hope it might help others too with similar issues. Lastly, if anyone proposes a solution which includes some code, please mention where I should paste it (I do have a bp-custom.php file).

Thanks in advance

I have now tried everything except rollback.

I have uninstalled and reinstalled buddypress. I have deactivated every single plugin except buddypress and I have even switched to the twenty-seventeen theme, with no custom code or anything. I am still getting an error when I add a user to a group. The error in my log says this:

Call to undefined function groups_record_activity() in /wp-content/plugins/buddypress/bp-groups/bp-groups-functions.php:588

So it seems the error is certainly to do with buddypress itself, right? Anyone got any suggestions?
