Add this before the function
global $bp;

[@shanebp Moderator 15 years ago]

It’s just a hack, across various php files

Add a block/unblock button on profile pages
When clicked either add or remove a row from a blocked_users db table via function in bp-custom
Check that table in bp-messages when sending messages & notifications
Check that table in bp-friends when a friend request is made

Works fine except for the initial “Friendship could not be requested” issue.

So any update can only have one link in it?

I don’t have a function for you, but I’d say you need to count the number of hrefs.
For anything over 1, remove everything between and including the href open and close tags.
Of course, the resulting update may not make sense, english-wise.

[@shanebp Moderator 15 years ago]

Got this to work by setting add_filter priority to 12

Remember to also filter on bp_get_activity_latest_update to handle links in member-header

[@shanebp Moderator 15 years ago]

I think this is the right approach, but it’s not working…

In bp-custom –

function add_target_func_callback($matches){
if ( (parse_url($matches[1], PHP_URL_HOST) != 'my.com') && (parse_url($matches[1], PHP_URL_HOST) != 'www.my.com') ){
$matches[0] = 'target="_blank" ' . $matches[0];
}
return $matches[0];
}

function add_target_blank($content) {
$content = preg_replace_callback('#href=['"]([^'"]*)['"]#i', 'add_target_func_callback', $content);
return $content;
}

add_filter('bp_get_activity_content_body', 'add_target_blank', 1, 1 );

I’m not sure that $content is being passed to add_target_blank

[@shanebp Moderator 15 years ago]

Simple typo ? Should be:

$username = $bp->loggedin_user->id;

[@shanebp Moderator 15 years ago]

Glad you got it working.

I’d love to see an example of this using an ajax call, about which I know little.
Please post your working example when you get there, thanks.

[@shanebp Moderator 15 years ago]

The link just goes to the page that it is on.
That’s what this does: bp_core_redirect( wp_get_referer() ) in bp_send_private_bzzt()

So a 404 indicates some other problem that I can’t diagnose, unless…

Did you try putting the code in bp-custom.php, per the instructions, instead of functions.php ?

[@shanebp Moderator 15 years ago]

You have to roll your own.
I got thru it awhile back with help from @r-a-y

https://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/send-private-static-message/

[@shanebp Moderator 15 years ago]

You’d have to use action or filter hooks if you put it in bp-custom

Try putting it in a template file, like member-header

[@shanebp Moderator 15 years ago]

My fix –

In bp-xprofile.php
In function xprofile_set_field_data

I changed this line
`if ( $is_required && ( empty( $value ) || !strlen( trim( $value ) ) ) ) { `

to
`if ( $is_required && ( empty( $value ) ) ) { `

And changes are now saved.
I do not know why the strlen check was causing a problem.

[@shanebp Moderator 15 years ago]

I use a version of this on profile pages (member-header.php) – it’s faster than the code in the url above because it only checks one user.

`
function check_is_user_online($user_id){
if ( bp_has_members( ‘type=online&include=’.$user_id) ) return true;
else return false;
}
$this_id = $bp->displayed_user->id;
$is_online = check_is_user_online($this_id);
if ($is_online) echo “NOW ONLINE”;
else bp_last_activity( $this_id );
`

[@shanebp Moderator 15 years ago]

Bit of a drag that we have to loop thru all members, but this works and I couldn’t figure out a better way

[@shanebp Moderator 15 years, 1 month ago]

The problem lay somewhere in memcache or varnish conditionals

The fix was to comment out this line in wp_includes/registration, function wp_update_user
wp_clear_auth_cookie();

[@shanebp Moderator 15 years, 1 month ago]

I’d use xprofile_get_field_data

Like so:
xprofile_get_field_data(‘your field name’, member_id);

[@shanebp Moderator 15 years, 1 month ago]

I tried Bowe’s method using W3 Total cache and Rackspace CDN (CloudFiles) for a 3 dedicated servers setup – 1 db, 2 frontend.
It failed at the crop avatar step. Everything else was fine.
We had to use NFS instead to sync avatars across the frontend servers – ugh.
Still using W3 Total cache for CDN for other files.

@Pisanojm: did MaxCDN allow use of CDN for avatars for you ?

[@shanebp Moderator 15 years, 1 month ago]

This is all new to me, but I think what is happening is that all file uploads are sent to CDN (Cloud Files). But BP does file operations (copying and creating thumbs, etc), on the file in the uploads dir, but the new files are not uploaded to CDN. The original file is deleted as it should be but on a display call the avatar shown is the default avatar because the call looks in CDN for a file that was never uploaded.

One approach might be to do the operations and then, in bp-core-avatars.php, upload to CDN.
But this isn’t just about avatars, it’s everything in the uploads folder.
So any subsequent operations would require getting the file from CDN rather than uploads, doing operations and then putting it back into the CDN. Not sure if this would work and if it did wouldn’t it waste bandwidth and increase time significantly.

Paul – any info you have re avatars to S3 would be appreciated, especially re GD operations on avatars.

[@shanebp Moderator 15 years, 1 month ago]

The cronjob approach didn’t work either.

So, the basic issue is still trying to keep the uploads folder synced across multiple servers.

If anyone has encountered this, please advise.

Rackspace server support is now suggesting
-local replication with rsync with persistence on the load balancer
or
-NFS (real-time synchronization)

[@shanebp Moderator 15 years, 1 month ago]

We were using a symlink – but it doesn’t support renaming files.
So we went with a every 1 minute cronjob instead.

The reason for all this was trying to keep the uploads folder synced across multiple servers.
So image processing will stay on server X, cronjob will pull all files to CDN, and all display calls will be routed to CDN.

This can search on custom profile fields
http://www.blogsweek.com/category/bp-profile-search/

[@shanebp Moderator 15 years, 1 month ago]

Thanks for the tip – works here.

[@shanebp Moderator 15 years, 1 month ago]

Adjustable ~Line 141 in bp-core-classes.php
`
if ( ‘online’ == $type )
$sql = “AND DATE_ADD( um.meta_value, INTERVAL 10 MINUTE ) >= UTC_TIMESTAMP()”;
`

[@shanebp Moderator 15 years, 1 month ago]

Solution
`
function user_nav_add_anchor() {
global $bp;
$bp->bp_nav .= “#your-anchor”;
$bp->bp_nav .= “#your-anchor”;
//etc
}
add_action( ‘wp_head’, ‘user_nav_add_anchor’,9 );
`
Anyone know of a way to do this with a loop through all the $bp->bp_nav[] fields ?

[@shanebp Moderator 15 years, 1 month ago]

Oops – thanks r-a-y.
I chopped down too much the function that I use.
Perhaps this better explains my approach:

`
function login_intercepts(){
global $bp_unfiltered_uri;

if ( is_user_logged_in() ) {
/* if user logs in at domain name url or logged-out, they are sent to /activity */
if ( ($bp_unfiltered_uri[0] == “”) || ($bp_unfiltered_uri[0] == “logged-out”) ) {
bp_core_redirect( get_option(‘siteurl’).”/activity” );
}

/* if user logs in on activate page, they are sent to /welcome */
if ( $bp_unfiltered_uri[0] == “activate” ) {
bp_core_redirect( get_option(‘siteurl’).”/welcome” );
}

//etc

}
}

add_action( ‘wp’, ‘login_intercepts’, 3 );
`
