This is part of buddypress. On activity page have meta title description “Side wide Activy – Name of web” a i want change this in bp-custom.php

I tryed to work also with this solution (provided by @shanebp too):
https://buddypress.org/support/topic/creating-a-new-order-by-filter-in-groups-loop-with-custom-sql/
but I do not obtain to order members by rating.. is this the right approach??

function antares_members_filter_options() {
    echo '<option value="rating">rating</option>';
}
add_action( 'bp_members_directory_order_options', 'antares_members_filter_options' );

function antares_ajax_querystring( $query_string, $object ) {

	if ( 'members' != $object ) 
		return $query_string;

	if ( ! bp_is_members_directory() ) 
		return $query_string;
	
	$query_args = wp_parse_args( $query_string, array() );

        $page = $query_args['page'];

	if( isset( $query_args['action'] ) && $query_args['action'] == 'rating' ) {
	
		$query_args = array();
		$query_args['page'] = $page;
		$query_args['orderby'] = 'rating';		
		$query_args['order'] = 'ASC';			
		$query_args['include'] = antares_get_members(); 
		$query_string = http_build_query( $query_args );

Hey, @danbp Thanks for the long and detailed response.

I’m fully aware of what you’re trying to convey the risk factors on this.. But as my requirements are different, I’ve completely disabled the media library and allowed access the users to each individual gallery only (negating the access of other’s files).. I’ve uploaded images hosted on sub-domains that completely separate from the main site.

All the activities that takes place on the site are on the front end.. The back end wp administrator dashboard are disabled for editing ( of course they are enabled for updating plugins & adding pages occasionally) as most of the pages are done in custom-template.. No admin or author level privileges are created on the site – just the subscriber as it’s mainly a networking site.. The idea that attaching the media button gives lots of flexibility to the users to resize the images or review them in the content area itself before they can post the activity.. Unless it’s a forums or community sites, for a networking sites, leaving alone with html codes or text editors may be (perhaps) discouraging impression for the social users.

I’m glad that you pointed out it’s more of a wordpress thing than buddypress.. I’ll have a look at the possibility of getting it work and let you know.

Thanks.

Hi, i put this:

define ( ‘BP_ENABLE_ROOT_PROFILES’, true );

add_filter( ‘bp_core_enable_root_profiles’, ‘__return_true’ );

I try in bp-custom. php and also in my function theme but not work

Every time i click in the activity page on the username (like email) do not work, 404 error

For example, if a username member is alex7@gmail.com and i click do not work, if is only alex7 it work perfect

The path is:

members/alex7@gmail.com/ DO NOT WORK

members/alex7/ WORK

Can you help me?

Thanks a lot
